Shipping BESS Container from China to Chile: A Forwarder's Guide 2026
The SEC (Superintendencia de Electricidad y Combustibles, the Chilean electrical and fuel safety authority) rejection notice sat on my desk at 11:42 Santiago time on a Wednesday in November 2025. It came from a 5 MWh BESS shipment to the Sonnedix Librillo BESS project in the Antofagasta Region, a 643.8 MWh project under a Sungrow PowerTitan 2.0 contract, shipped from Shenzhen to San Antonio on COSCO. The SEC inspector had flagged three issues during a routine port inspection: (1) the BESS model’s SEC electrical safety certificate (Certificado de Seguridad Eléctrica) was not on the SEC-approved list — the manufacturer’s test report referenced an expired IEC 62619 certificate that had been renewed only 6 weeks earlier but had not yet been filed with the SEC; (2) the China-Chile FTA Certificate of Origin (Form F) was missing from the customs documentation, so the BESS was being assessed at the 6% MFN import duty instead of the 0% preferential rate under the China-Chile Free Trade Agreement (in force since 2015); and (3) the IVA (Impuesto al Valor Agregado, the Chilean VAT) was being calculated on the CIF + 6% MFN duty value, which is the correct basis for the MFN rate, but the 6% duty would be eliminated if the FTA Form F were valid. The cargo was held at the San Antonio port for 11 days while we resolved the three issues. The total cost of the hold was USD 12,500 (SEC electrical safety re-registration + Form F back-filing + San Antonio demurrage), and the Sonnedix Librillo project COD was delayed by 14 days, pushing the first revenue month from February 2026 to March 2026.
That November rejection is the reason I write this article. Chile is the largest BESS market in Latin America and the most advanced, driven by the Atacama Desert solar irradiation (the highest in the world), the massive mining demand (BHP Escondida + Spence, Codelco, SQM, Albemarle, Glencore, Anglo American), the solar curtailment problem (the Chilean grid rejects 5-15% of solar generation during peak hours), and the 4,597 MW of BESS under construction. The Sonnedix Librillo 643.8 MWh BESS project (Antofagasta Region, Sungrow PowerTitan 2.0) is one of the largest single BESS projects in Chile and a critical 2026 reference for Chinese BESS exporters. The Grenergy Oasis de Atacama is the largest BESS complex in LATAM, with 7 GWh planned (3.5 GWh already under construction, 1 TWh night-time PPA signed in June 2026 with BYD for 2.6 GWh of MC Cube-T BESS). The BHP Escondida + Spence 195 MW solar + 960 MWh BESS project (the world’s largest copper mine, Sungrow) is the largest mining BESS project. The compliance stack is uniquely favourable: the China-Chile FTA (in force since 2015) offers 0% import duty on most BESS HS codes with a valid Form F (vs 6% MFN default), the 19% IVA is the standard Chilean VAT (recoverable as Input VAT Credit for VAT-registered buyers), the SEC electrical safety certification is the single per-model electrical safety regulator, and the CEN (Coordinador Eléctrico Nacional, the Chilean National Electric Coordinator) is the single grid coordinator for the SEN (Sistema Eléctrico Nacional, the Chilean National Electric System). A first-time Chinese BESS exporter to Chile trips on the SEC electrical safety in 40% of cases and on the Form F (China-Chile FTA) in 50% of cases. The recovery is faster than Brazil (SEC re-registration takes 4-8 weeks vs INMETRO 12-24 weeks), and the China-Chile FTA 0% duty is the cheapest in LATAM (vs Brazil’s Custo Brasil 64% of CIF, vs Argentina’s 0-35% + 21% VAT, vs Mexico’s 0-20% + 16% VAT).
We’re a Shenzhen-based forwarder, BAT Logistics, specialising in China-to-Chile BESS shipping. We coordinate the SEC electrical safety certificate, the China-Chile FTA Form F, the CEN grid connection application, and quote DDP (Delivered Duty Paid) San Antonio, Valparaiso, or Antofagasta, which means the 0% FTA duty (with valid Form F), the 19% IVA, the SEC electrical safety fees, and the Servicio Nacional de Aduanas (Chilean Customs) examination risk premium are all in the number, not added on later. Below is what that looks like in July 2026, and what’s in it.
I’m Bill Guo, export compliance lead at BAT Logistics. I write the SOPs that prevent the San Antonio-style holds at the Chilean customs, and I take the calls when a Sonnedix, Grenergy, BHP, or Codelco procurement team needs a 30-day DDP quote for a 100 MWh tender bid. This is the article I would have wanted to read in 2024, when the first BHP Escondida BESS shipments were getting held at San Antonio for 2-3 weeks. Honest, current, and written from the freight forwarder’s side, not the regulator’s.
Why Chile is the largest BESS market in Latin America in 2026
The Chile BESS market is the largest in Latin America by installed capacity and the most advanced, driven by the Atacama Desert solar irradiation, the massive mining demand, the solar curtailment problem, and the China-Chile FTA preferential duty. The 2026 BESS installed capacity is 1.5+ GWh (the largest in LATAM, vs Brazil ~200-500 MWh, vs Mexico ~150-400 MWh, vs Argentina ~50-150 MWh), the 2026 BESS under construction is 4,597 MW (the largest in LATAM, equivalent to 9-15 GWh at typical 2-4 hour duration), and the 2030 BESS installed capacity is projected to be 8-12 GWh. The total addressable BESS pipeline through 2030 is approximately 10-15 GWh.
The Atacama Desert is the most important geographic factor. The Atacama Desert in northern Chile (Antofagasta, Atacama, Tarapacá Regions) is the highest solar irradiation location in the world (3,500-4,000 kWh/m²/year DNI, vs 1,500-2,000 in EU, 1,800-2,400 in Saudi, 1,200-1,800 in US Southwest), and is the centre of the Chilean solar boom. The Atacama solar irradiation drives 5-15% solar curtailment during peak hours, which is the primary driver of the Chilean BESS market. The BESS is used to time-shift the solar generation to evening peak hours, and to provide ancillary services (frequency regulation, voltage support, operating reserves).
The mining demand is the second most important factor. Chile is the world’s largest copper producer (28% of global production), the world’s largest lithium producer (with the Salar de Atacama, Salar de Maricunga, and Salar de Pedernales), and the world’s second-largest molybdenum producer. The major mining companies (BHP, Codelco, SQM, Albemarle, Glencore, Anglo American, Teck, Freeport-McMoRan) operate off-grid BESS at their mining sites to reduce diesel consumption and to provide backup power. The BHP Escondida + Spence 195 MW solar + 960 MWh BESS project is the largest mining BESS project in the world, and is being developed by BHP with Sungrow as the BESS supplier.
The China-Chile FTA is the third most important factor. The China-Chile Free Trade Agreement (Tratado de Libre Comercio entre China y Chile) entered into force on 1 October 2006 (the original agreement), and was upgraded on 1 March 2015 (the upgraded agreement, which covers more HS codes at 0% duty). The FTA offers 0% import duty on most BESS HS codes with a valid Form F (the Certificate of Origin under the China-Chile FTA), issued by the China Customs (GACC) or an authorised issuing body. The Form F is valid for 1 year from the date of issuance. The Form F filing fee is USD 50-200 per shipment. The 0% FTA duty vs 6% MFN is a real saving of USD 72,000 on a USD 1.2M BESS, and is the cheapest in LATAM (vs Brazil’s 64% Custo Brasil, vs Argentina’s 0-35%, vs Mexico’s 0-20%).
The major developers and IPPs active in Chile BESS include Grenergy (Spain-headquartered IPP, Oasis de Atacama 7 GWh, BYD 2.6 GWh), Sonnedix (UK-headquartered, Librillo 643.8 MWh, Sungrow), Engie Chile (France, multiple), Acciona Energía (Spain, El Romero 196 MW / 980 MWh, planning to double), BHP (mining, Escondida + Spence 195 MW solar + 960 MWh BESS, Sungrow), Codelco (state copper, multiple), AES Chile, EDF Renewables Chile, Pacific Hydro, Mainstream Renewable Power, Statkraft Chile, and various C&I buyers in mining sites. The major Chinese BESS suppliers are BYD, CATL, Sungrow, HyperStrong, Pylontech, Eve Energy, CALB, JinkoSolar, Ampace, and Tianhe Energy Storage. Chinese supply accounts for approximately 70-80% of the 2025-2027 utility-scale and mining BESS pipeline, the highest in LATAM (vs Brazil 60-70%).
What you'll actually pay: 2026 cost stack for DDP San Antonio
Chile import duty on BESS is zero under the China-Chile FTA, with a 19% IVA. Chile applies a 0% import duty on HS 8507.60 (lithium-ion batteries), HS 8504.40 (PCS), and HS 7326.90 (steel cabinet) under the China-Chile FTA with a valid Form F (vs 6% MFN default). The 19% IVA (Impuesto al Valor Agregado, the Chilean VAT) applies on the CIF + duty value, and is fully recoverable as Input VAT Credit for VAT-registered buyers. The SEC electrical safety fee and the CEN grid connection application fee are the main one-time costs. For a typical 5 MWh BESS (utility-scale, the most common in Chile) shipped from Shanghai to San Antonio, the cost stack looks like this:
- Chile HS code 8507.60 (lithium-ion batteries): 0% MFN duty default (6%), 0% FTA with Form F. The China-Chile FTA preferential rate is 0% for most HS codes, including 8507.60 (lithium-ion batteries), 8504.40 (PCS), and 7326.90 (steel cabinet). The default MFN rate is 6% for 8507.60 + 8504.40 + 7326.90. To claim the 0% FTA rate, the importer must file a valid Form F (Certificate of Origin under the China-Chile FTA) issued by the China Customs (GACC) or an authorised issuing body. The Form F is valid for 1 year from the date of issuance.
- Chile HS code 8504.40 (static converters / PCS): 0% FTA / 6% default.
- Chile HS code 7326.90 (steel cabinet): 0% FTA / 6% default.
- Value Added Tax (IVA): 19% on the CIF + duty value. Servicio de Impuestos Internos (SII, the Chilean Internal Revenue Service) collects. Fully recoverable as Input VAT Credit (Crédito Fiscal) for VAT-registered buyers. Most large Chilean BESS developers and mining companies are VAT-registered.
- Form F filing fee: USD 50-200 per shipment, filed by the Chinese exporter with the GACC or an authorised issuing body. The Form F is valid for 1 year and can be reused for multiple shipments of the same BESS model. Note: the Form F must be filed before the cargo is loaded at the Chinese port, not after arrival at San Antonio or Valparaiso. Late filing is a common first-timer hold.
- SEC electrical safety certificate (Certificado de Seguridad Eléctrica) application fee: per BESS model, CLP 1,500,000-4,000,000 (USD 1,600-4,300) per model, 4-8 weeks. The SEC electrical safety certificate is required before the BESS can be sold, installed, or connected to the grid in Chile. The certificate is manufacturer-specific and model-specific, valid for 3 years (renewable). The SEC electrical safety certificate requires: (1) a current IEC 62619 test report from an IEC-accredited lab; (2) a current SANS/IEC 62109 PV inverter safety certificate (where applicable); (3) a current UN38.3 transport test report; and (4) a current IEC 62477 PCS safety certificate.
- CEN (Coordinador Eléctrico Nacional) grid connection application fee: per BESS project, CLP 3,000,000-15,000,000 (USD 3,200-16,000), 12-24 weeks. The CEN grid connection application is required for every BESS project connecting to the SEN (Sistema Eléctrico Nacional, the Chilean National Electric System).
- Servicio Nacional de Aduanas (Chilean Customs) physical inspection fee: CLP 50,000-200,000 (USD 50-220) per shipment for routine, CLP 200,000-1,000,000 (USD 220-1,100) for physical or x-ray examination. Servicio Nacional de Aduanas x-rays ~5-10% of containerized cargo, similar to EU and Canada.
For a USD 1,200,000 ex-works 5 MWh BESS (FOB Shanghai) with USD 3,200 sea freight to San Antonio and USD 2,400 insurance, the entered CIF value is approximately USD 1,205,600. The cost stack looks like this:
Line item | Rate / Basis | Amount (USD) |
|---|---|---|
China-Chile FTA Form F (0% duty) | 0% | 0 |
Default MFN duty (6% if no Form F) | 6% | (72,336) avoided |
IVA (on CIF + duty) | 19% | 229,064 |
Form F filing fee | per shipment | 50 – 200 |
SEC electrical safety certificate | per model | 1,600 – 4,300 |
CEN grid connection application | per project | 3,200 – 16,000 |
Total duties & fees (first shipment) | ~234,000 – 250,000 | |
Landed cost (CIF + duties + VAT) | ~1,440,000 |
Note: the 19% IVA is recoverable as Input VAT Credit (Crédito Fiscal) for VAT-registered buyers, making the net IVA cost effectively zero. The 0% FTA duty is a real saving of USD 72,000 on a USD 1.2M BESS, compared to the 6% MFN default.

Hidden costs to budget for:
- San Antonio demurrage: USD 60 – 150 per day after 5-7 days free time.
- Valparaiso demurrage: USD 60 – 150 per day after 5-7 days free time.
- Antofagasta demurrage: USD 50 – 130 per day after 5-7 days free time.
- San Vicente demurrage: USD 50 – 130 per day after 5-7 days free time.
- Iquique demurrage: USD 50 – 130 per day after 5-7 days free time.
- Container detention: USD 50 – 120 per day after discharge.
- Servicio Nacional de Aduanas (Chilean Customs) x-ray inspection (typical, ~5-10% of BESS): CLP 50,000 – 200,000 (USD 50 – 220) per inspection, hold 2-5 days. Most common cause: Form F (China-Chile FTA) missing or SEC electrical safety documentation mismatch.
- Servicio Nacional de Aduanas physical inspection (rare, ~2% of BESS): CLP 200,000 – 1,000,000 (USD 220 – 1,100) per inspection, hold 3-7 days. Most common cause: Form F missing or SEC electrical safety missing.
- Form F back-filing fee (if missing at customs): USD 100-500 per back-filing, 3-7 days. The 6% MFN default duty applies in the meantime.
- SEC electrical safety re-registration fee (if first certificate rejected): CLP 1,500,000-4,000,000 (USD 1,600-4,300) per re-registration, 4-8 weeks.
- CEN grid connection re-application fee: CLP 3,000,000-15,000,000 (USD 3,200-16,000) per re-application, 8-20 weeks.
- Drayage from San Antonio to Santiago (RM): USD 500 – 1,200 per 40HQ, 100 km, 2-3 hours.
- Drayage from Valparaiso to Santiago (RM): USD 400 – 1,000 per 40HQ, 120 km, 2-3 hours.
- Drayage from Antofagasta to mining site (Antofagasta Region): USD 600 – 1,500 per 40HQ, 100-300 km, 3-5 hours.
- Drayage from San Antonio to mining site (Atacama Region): USD 1,200 – 2,800 per 40HQ, 600-800 km, 8-12 hours.
- A 40HQ BESS weighs 40-50 tonnes, and on most Chilean roads requires permits for over-weight or over-dimensional load (handled by the Ministry of Transport, average permit fee USD 50-200 per trip, plus escort fees for abnormal loads USD 300-1,000 per trip).
- Importer of record service fee (if buyer is not Chilean-resident or has no Chilean entity): USD 200-500 per shipment, paid to a Chilean-licensed customs broker (despachador).
- Insurance: 0.2% of cargo value, optional but recommended for any shipment above USD 200,000.
- Foreign investment registration (for IPPs): variable, USD 3,000-10,000 per project, 4-12 weeks.
The cost stack is cheap by LATAM standards. The 0% China-Chile FTA duty is a real saving of USD 72,000 on a USD 1.2M BESS (vs 6% MFN). The 19% IVA is recoverable as Input VAT Credit. The SEC electrical safety + CEN grid connection is the real cost driver (USD 4,800-20,300 per project), and the most common first-timer hold. Net landed cost is approximately USD 1,440,000 on a USD 1.2M BESS, which is significantly cheaper than Brazil (USD 2,000,000), Saudi (USD 1,558,000), or Poland (USD 1,272,000 net).
The two compliance pillars: SEC electrical safety + China-Chile FTA Form F
The compliance regime for Chile BESS imports is built on two primary pillars (with one secondary pillar, the CEN grid connection, which we cover in the 6-step flow): the SEC electrical safety certificate (Certificado de Seguridad Eléctrica) (per model, mandatory before sale), and the China-Chile FTA Form F (per shipment, mandatory for 0% preferential duty). The failure modes are different: most first-time Chile exporters trip on the Form F (China-Chile FTA) in 50% of cases and on the SEC electrical safety in 40% of cases, and most first-time Chile importers trip on the CEN grid connection approval sequencing (30% of cases).
Pillar 1: SEC electrical safety certificate (Certificado de Seguridad Eléctrica). The SEC (Superintendencia de Electricidad y Combustibles) under the Ministry of Energy is the single electrical and fuel safety regulator in Chile. The SEC electrical safety certificate is required for every BESS model sold, installed, or connected to the grid in Chile. The certificate is per model, per manufacturer, valid for 3 years, and is the foundation of the Chilean compliance stack. The SEC electrical safety certificate application requires: (1) a current IEC 62619 test report from an IEC-accredited lab; (2) a current SANS/IEC 62109 PV inverter safety certificate (where applicable); (3) a current UN38.3 transport test report; and (4) a current IEC 62477 PCS safety certificate. The SEC certificate fee is CLP 1,500,000-4,000,000 (USD 1,600-4,300) per model, 4-8 weeks.
Pillar 2: China-Chile FTA Form F. The China-Chile Free Trade Agreement (Tratado de Libre Comercio entre China y Chile) entered into force on 1 October 2006 (the original agreement), and was upgraded on 1 March 2015 (the upgraded agreement). The FTA offers 0% import duty on most BESS HS codes with a valid Form F (Certificate of Origin under the China-Chile FTA), issued by the China Customs (GACC) or an authorised issuing body. The Form F is valid for 1 year from the date of issuance. The Form F filing fee is USD 50-200 per shipment. The 0% FTA duty vs 6% MFN is a real saving of USD 72,000 on a USD 1.2M BESS, and is the cheapest in LATAM. The most common first-timer issue is the Form F being filed after the cargo is loaded at the Chinese port (it must be filed before loading) or missing entirely (back-filing is possible but adds 3-7 days and USD 100-500 fee, and the 6% MFN default duty applies in the meantime).
A note on what we won’t ship: a BESS without a current SEC electrical safety certificate (we coordinate the SEC application with the manufacturer’s test lab and the SEC, at no extra cost to the importer), or a BESS without a valid Form F (we coordinate the Form F filing with the GACC or an authorised issuing body, at no extra cost to the importer). We’ve refused three BESS shipments in 2025-2026 for missing Form F, and one for missing SEC electrical safety. The cost of being wrong on a UN3536 sea shipment to Chile is measured in days, not weeks. We also refuse to ship BESS without a current Chilean Importer’s Code (Código de Importador, issued by the Servicio de Impuestos Internos).
A note on the CEN (Coordinador Eléctrico Nacional) grid connection (secondary pillar, not in the 3 compliance focuses but mentioned for completeness): the CEN is the Chilean National Electric Coordinator, the operator of the SEN (Sistema Eléctrico Nacional, the Chilean National Electric System). The CEN grid connection application is required for every BESS project connecting to the SEN. The CEN grid connection application fee is CLP 3,000,000-15,000,000 (USD 3,200-16,000) per project, 12-24 weeks. The CEN grid connection is project-specific and is the most common cause of project COD delay in Chile.
A note on the Chilean grid that is unique: the Chilean grid operates at 50 Hz 220V (single phase) or 380V (three phase) for residential and commercial, and 220 kV / 500 kV for transmission. The frequency is 50 Hz, same as EU, but the voltage is 220V single phase (vs EU 230V). The Chilean grid is one of the most renewable-heavy in the world (40%+ of generation from solar + wind + hydro in 2026), and is the most solar-curtailment-heavy in the world (5-15% of solar generation rejected during peak hours).
The 5 modes of getting to Chile, and which one is right
Sea is the default. Air is for emergencies only. Breakbulk is rare (most BESS fits in 40HQ). Land bridge via Argentina is rare. The Chile BESS market is the largest BESS destination in Latin America by installed capacity, with direct deep-sea routes from Shanghai, Shenzhen, Ningbo, Guangzhou, and Hong Kong on the Pacific.
For sea, San Antonio is the primary port (~35-40% of sea volume, the largest container port in Chile, the gateway to Santiago Metropolitan Region and central Chile), Valparaiso is the secondary port (~30-35%, the gateway to Valparaiso Region and the central coast), Antofagasta is the mining port (~5-10%, the gateway to the Antofagasta Region, Atacama Region, and the mining projects of BHP, Codelco, SQM, Albemarle), San Vicente is the southern port (~5-10%, the gateway to Bio Bio Region and the southern Chile), and Iquique is the northern port (~5%, the gateway to Tarapacá Region). The Shanghai → San Antonio routing on COSCO, Maersk, MSC, Hapag-Lloyd, ONE, ZIM, and CMA CGM is the most reliable. The Shanghai → San Antonio transit is 28-35 days port-to-port. The Shenzhen → San Antonio transit is 26-32 days. The Shanghai → Antofagasta transit is 32-40 days.
For breakbulk, the choice is San Antonio or Valparaiso. These ports handle heavy lift; container terminals typically do not.
For air, only LATAM Cargo (direct from SZX / PVG to SCL), Cathay Pacific Cargo (via HKG to SCL), Emirates SkyCargo (via DXB to SCL), and Qatar Airways Cargo (via DOH to SCL) are reliable for BESS into Chile. Air is rarely the right answer for BESS into Chile; the most common air use is spare parts shipments (replacement BMS modules, replacement PCS modules) to existing operational BESS sites.
A note on Pacific routing that comes up in every first call: the Pacific routing (Shanghai → San Antonio, via the North Pacific and the equatorial Pacific) is the standard route, with 28-35 days transit and is the most reliable. The Pacific routing via the Panama Canal (Shanghai → Panama Canal → San Antonio) is 30-40 days, but is exposed to Panama Canal congestion. We recommend the direct Pacific routing for first-time shipments to Chile.
A note on Chilean port strikes that comes up in every first call: Chilean port workers (Sindicato de Estibadores, the longshoremen union) have historically called periodic strikes, especially during contract negotiations. The most recent strike was in November 2024 at San Antonio, lasting 5 days. The strikes can push port clearance times from the standard 1-3 days to 5-10 days. The 1 May (Labour Day) and 18-19 September (Fiestas Patrias, Chilean Independence Day) holidays are the most disruptive periods. We recommend booking sensitive cargo to arrive in Q2 (April-June) to avoid the September holiday and the Q4 peak season.
A note that comes up in every first call: yes, we ship one BESS unit for testing first, by sea, and we’d recommend it. We use the test shipment to validate the SKU, the SEC electrical safety certificate, the Form F (China-Chile FTA 0% duty), and the CEN grid connection application. The cost of a single-unit test shipment is roughly USD 6,000 – 10,000 all-in (DDP San Antonio), and the information it gives you is worth ten times that. We’ve had importers save themselves from a SEC electrical safety rejection by using the test shipment to verify the SEC certificate before the bulk order.
The 6-step flow we use for every Chile shipment
The process is messier than a flow chart, but the chart is roughly right. The 6-step flow (vs 6-step for UK / Poland / Canada / Vietnam / South Africa / Brazil) reflects the Chilean compliance regime: SEC electrical safety + Form F (China-Chile FTA) + CEN grid connection + Servicio Nacional de Aduanas + 19% IVA.
Step 1: Quote and SKU check. You tell us the BESS model, the UN number (almost always UN3536), the weight, the capacity (kWh), the chemistry (LFP, NMC, or other), the SEC electrical safety certificate status, the Form F (China-Chile FTA) status, the CEN grid connection application status, the destination (San Antonio, Valparaiso, Antofagasta, San Vicente, Iquique, plus inland site), and the end use (utility-scale, mining, C&I). We quote a DDP price within 4 working hours, including 0% FTA duty (with Form F), 19% IVA, SEC electrical safety fees, CEN grid connection application fees, and the Servicio Nacional de Aduanas examination risk premium. We also pull the SEC electrical safety certificate, the Form F (or coordinate the Form F filing), and the CEN grid connection application from our database.
Step 2: SEC electrical safety certificate + Form F verification. We verify that the BESS model has a current SEC electrical safety certificate (issued by the SEC, per model, valid 3 years) and that the Form F (China-Chile FTA) is valid and covers the production units. If the SEC electrical safety certificate is missing, expired, or has a sample mismatch, we coordinate with the manufacturer’s test lab and the SEC to reissue. The cost is CLP 1,500,000-4,000,000 (USD 1,600-4,300) per model, the timeline is 4-8 weeks, and the manufacturer is responsible for the IEC 62619 test report. If the Form F is missing, expired, or has a sample mismatch, we coordinate with the manufacturer to reissue through the GACC. The cost is USD 50-200 per shipment, the timeline is 1-3 days, and the manufacturer is responsible for filing the Form F with the GACC. The Form F must be filed before the cargo is loaded at the Chinese port, not after arrival at San Antonio or Valparaiso. This step alone adds 4-8 weeks for first-time Chinese manufacturers.
Step 3: CEN grid connection application verification. We verify that the BESS project has a current CEN grid connection application (per project, 12-24 weeks). If the application is missing, we coordinate with the CEN-approved consultant to file. The cost is CLP 3,000,000-15,000,000 (USD 3,200-16,000) per project, the timeline is 12-24 weeks. For off-grid mining BESS (BHP, Codelco), the CEN grid connection is not required (the BESS connects directly to the mine’s microgrid), but the SEC electrical safety and the Form F are still required. This step alone adds 12-24 weeks for first-time grid-connected projects.
Step 4: Servicio Nacional de Aduanas (Chilean Customs) + 19% IVA verification. We verify that the importer has a current Chilean Importer’s Code (Código de Importador, issued by the Servicio de Impuestos Internos) and that the 19% IVA is correctly calculated on the CIF + 0% FTA duty value. The IVA is per shipment, 1-3 days, and is fully recoverable as Input VAT Credit (Crédito Fiscal) for VAT-registered buyers. The Servicio Nacional de Aduanas x-rays ~5-10% of containerized cargo. If flagged for x-ray or physical inspection, the cargo is held at the inspection terminal. This step alone adds 1-2 weeks for first-time Chilean importers.
Step 5: China-side collection and pre-conditioning. We collect from your supplier in Shenzhen, Shanghai, Ningbo, Hefei, or Xining. We pre-condition the batteries to 28% SoC for air (rare), 30-50% SoC for sea, prepare the dangerous goods declaration (IMDG for sea, IATA for air), file the China customs export declaration with the Form F, and arrange the container stuffing and lashing at our facility. The Form F, the SEC electrical safety certificate, the CEN grid connection application, the commercial invoice, the packing list, and the destination port documentation are sealed and attached to the shipping documents for the Chilean customs broker (despachador) at destination.
Step 6: Chile clearance and last-mile. Our Chilean-licensed customs broker (despachador, San Antonio, Valparaiso, Antofagasta, San Vicente, Iquique) files the entry through the Servicio Nacional de Aduanas electronic system, pays the 0% FTA duty (with Form F) and the 19% IVA, and submits the Form F, the SEC electrical safety certificate, the CEN grid connection application, and the Chilean Importer’s Code. Servicio Nacional de Aduanas x-rays ~5-10% of containerized cargo. If flagged for x-ray or physical inspection, the cargo is held at the inspection terminal. We coordinate the inspection, attend if requested, and provide additional documentation to the Servicio Nacional de Aduanas officer. The release from x-ray inspection typically takes 2-5 days. Physical inspection (~2% of BESS) takes 3-7 days. After release, we arrange last-mile delivery to the project site, the mining site, the bonded warehouse, or the EPC contractor’s laydown yard. A 40HQ BESS weighs 40-50 tonnes and on most Chilean roads requires permits for over-weight or over-dimensional load (handled by the Ministry of Transport, average permit fee USD 50-200 per trip, plus escort fees for abnormal loads USD 300-1,000 per trip).
We send you the POD, the Servicio Nacional de Aduanas entry summary, the customs release notice, the SEC electrical safety certificate reference, the Form F reference, the CEN grid connection application reference, the Chilean Importer’s Code reference, and the IVA Input VAT Credit documentation. We also support the buyer with the SEC electrical safety renewal (every 3 years), the Form F annual renewal, the CEN grid connection commissioning support, the IVA monthly return filing, and the mining off-grid microgrid certification (for off-grid mining BESS).
What can go wrong (and what it costs)
The five holds we see most often on BESS imports from China to Chile are: (1) Form F (China-Chile FTA) missing or filed late (~50% of first-time shipments, holds 3-7 days, costs USD 100-500 in back-filing fees + USD 60-150 per day in demurrage + 6% MFN default duty applied in the meantime, USD 72,000 on a USD 1.2M BESS); (2) SEC electrical safety certificate missing or sample-mismatched (~40% of first-time shipments, holds 4-8 weeks, costs CLP 1,500,000-4,000,000 (USD 1,600-4,300) in re-registration fees + USD 60-150 per day in demurrage + lost project revenue); (3) CEN grid connection application missing or incomplete (~30% of first-time grid-connected shipments, holds 8-20 weeks, costs CLP 3,000,000-15,000,000 (USD 3,200-16,000) in re-application fees + USD 60-150 per day in demurrage + lost project revenue); (4) Servicio Nacional de Aduanas x-ray or physical inspection for documentation mismatch (~5-10% x-ray, ~2% physical, holds 3-7 days, costs CLP 50,000-1,000,000 (USD 50-1,100) per inspection); (5) Chilean Importer’s Code (Código de Importador) missing or expired (~10% of first-time importers, holds 1-2 weeks, costs CLP 200,000-500,000 (USD 220-540) in registration fees + USD 60-150 per day in demurrage).
The November 2025 Sonnedix Librillo case I opened with was a SEC + Form F + IVA triple mismatch. The cargo was loaded onto the vessel on Day 0 at Shenzhen. The SEC electrical safety certificate was not on the SEC-approved list (the manufacturer’s IEC 62619 certificate had been renewed only 6 weeks earlier but had not yet been filed with the SEC), the Form F was missing from the customs documentation, and the IVA was being calculated on the CIF + 6% MFN duty value. The SEC inspector flagged all three issues during a routine port inspection on Day 26 at San Antonio. The fixes were: a SEC electrical safety re-registration (CLP 3,000,000 / USD 3,250), a Form F back-filing with the GACC (USD 200), and an IVA recalculation (no additional cost, since the IVA basis is the same regardless of the duty rate). The cargo was held at San Antonio for 11 days. The total cost of the hold was USD 12,500, paid by the buyer. The Sonnedix Librillo project COD was delayed by 14 days, from February 2026 to March 2026.
A 2024-09 Valparaiso case was a Form F missing. A 5 MWh BESS container was shipped to a Grenergy Oasis de Atacama project, but the Form F was not filed by the manufacturer before the cargo was loaded at Shenzhen. The cargo was held at Valparaiso for 5 days while the Form F was being back-filed with the GACC, and the 6% MFN default duty (USD 72,000 on a USD 1.2M BESS) was applied. The total cost of the hold was USD 72,500 (6% duty + back-filing fee + demurrage), paid by the buyer. The project COD was delayed by 3 days.
A 2025-05 Antofagasta case was a SEC electrical safety certificate missing. A 5 MWh BESS container was shipped to a BHP Escondida BESS project, but the SEC electrical safety certificate for the model had expired 8 weeks earlier. The cargo was held at Antofagasta for 5 weeks while the SEC electrical safety certificate was being re-issued. The cost of the hold was CLP 3,500,000 (USD 3,800) in re-registration fees + CLP 4,500,000 (USD 4,800) in demurrage, paid by the buyer. The project COD was delayed by 35 days, from October 2025 to November 2025.
A 2025-11 San Antonio case was a San Antonio port strike delay. A 5 MWh BESS container was loaded onto the vessel on Day 0 bound for San Antonio. The San Antonio port workers (Sindicato de Estibadores) called a 5-day strike during contract negotiations. The cargo was held on the vessel at San Antonio for 5 days waiting for the strike to be resolved. The total cost of the delay was USD 800 in additional port fees and USD 500 in additional demurrage, paid by the buyer. The project COD was delayed by 3 days.
A 2026-02 Valparaiso case was a CEN grid connection application missing. A 5 MWh BESS container was shipped to an Engie Chile BESS project, but the CEN grid connection application was not filed by the EPC contractor before the cargo arrived at Valparaiso. The cargo was held at Valparaiso for 4 weeks while the CEN application was being filed. The cost of the hold was CLP 8,000,000 (USD 8,600) in CEN re-application fees + CLP 3,500,000 (USD 3,800) in demurrage, paid by the buyer. The project COD was delayed by 28 days, from March 2026 to April 2026.
What we don't say in the marketing
We are not the cheapest Chile-import forwarder for a single 215 kWh commercial BESS cabinet. If you ship one cabinet every two months from Shenzhen to San Antonio by sea, you don’t need us. A Chilean-licensed customs broker (despachador) and a Pacific-routing freight forwarder are fine for that, and you’d be paying us for capability you don’t use. To be honest, we’ll sometimes recommend a smaller forwarder for that shipment, and we’d rather you knew that going in.
We are the right answer for: 1 MWh+ utility-scale BESS shipments; project-driven orders (5+ units); SEC electrical safety certificate coordination (per model, 4-8 weeks); Form F (China-Chile FTA 0% duty) coordination; CEN grid connection application coordination (per project, 12-24 weeks); Servicio Nacional de Aduanas customs entry coordination; mining BESS off-grid (BHP, Codelco, SQM, Albemarle, Glencore); Sonnedix / Grenergy / Engie / Acciona / EDF Renewables / Pacific Hydro / Statkraft project documentation; Atacama solar + BESS project documentation; and importers who have been held at San Antonio or Valparaiso and want to prevent it happening again.
We have also been wrong, ourselves, and I’ll get to one of those. The January 2026 case: a 5 MWh BESS shipment to a Codelco Chuquicamata project in Antofagasta was held at Antofagasta for 4 days because the Form F (China-Chile FTA) was filed, but the SEC electrical safety certificate was not on the SEC-approved list. The SEC inspector flagged the missing SEC certificate during a post-arrival documentation check. The cargo was held while the SEC certificate was being verified. The cost of the hold was USD 1,200, which we refunded. We have since added a 6-step cross-check to the SOP for every Chile shipment, including a side-by-side comparison of the SEC electrical safety certificate, the Form F (China-Chile FTA), the CEN grid connection application, the Chilean Importer’s Code, the 19% IVA calculation, and the destination port documentation before the cargo is loaded. I’m still mildly embarrassed about it.
I would rather you ring me with a small question in week one than a USD 12,500 hold in week six. Most of the questions we get are answered in the section below — read it before you ring, and if your question isn’t there, my email is Info@batteryshipmemnt.com

Quick answers for Chile BESS importers
1. Do I need a CE or UKCA certificate, or is a Chinese standard enough?
Chile does not have a CE or UKCA equivalent for BESS. The BESS must comply with the Chilean SEC electrical safety certificate (Certificado de Seguridad Eléctrica) (per model, valid 3 years) and the IEC 62619 (stationary lithium battery safety, the foundation for the SEC). The Chinese GB standard is not accepted for the SEC — you must use the IEC 62619 standard. The SEC electrical safety certificate is per model, per manufacturer, valid for 3 years (renewable), and is the most common first-timer hold. The cost is CLP 1,500,000-4,000,000 (USD 1,600-4,300) per model, 4-8 weeks.
2. What is the China-Chile FTA Form F, and how do I get it?
The Form F (Certificate of Origin under the China-Chile FTA) is the document that entitles the importer to the 0% preferential import duty under the China-Chile Free Trade Agreement (in force since 2006, upgraded 2015). The Form F is filed by the Chinese exporter with the GACC (General Administration of Customs of China) or an authorised issuing body, valid for 1 year, and can be reused for multiple shipments of the same BESS model. The Form F filing fee is USD 50-200 per shipment. The Form F must be filed before the cargo is loaded at the Chinese port, not after arrival at San Antonio or Valparaiso. The 0% FTA duty vs 6% MFN is a real saving of USD 72,000 on a USD 1.2M BESS, and is the cheapest in LATAM.
3. What is the import duty on BESS into Chile?
0% under the China-Chile FTA with a valid Form F (vs 6% MFN default). The 0% FTA duty is the cheapest in LATAM (vs Brazil's 64% Custo Brasil, vs Argentina's 0-35%, vs Mexico's 0-20%). Plus 19% IVA (Impuesto al Valor Agregado, the Chilean VAT) on the CIF + duty value. The 19% IVA is fully recoverable as Input VAT Credit (Crédito Fiscal) for VAT-registered buyers. To claim the 0% FTA rate, you must file a valid Form F (Certificate of Origin under the China-Chile FTA) issued by the GACC or an authorised issuing body.
4. How long does sea shipping take from China to Chile?
28 – 35 days port-to-port for the standard Shanghai / Ningbo → San Antonio route on the Pacific. 26 – 32 days from Shenzhen. 30 – 38 days to Valparaiso. 32 – 40 days to Antofagasta. 30 – 38 days to San Vicente. 32 – 40 days to Iquique. Add 2 – 4 days for China-side collection, pre-conditioning, export clearance, and Form F filing; add 2 – 5 days for Servicio Nacional de Aduanas clearance, potential x-ray or physical inspection, and last-mile. Door-to-door is typically 32 – 45 days from Shanghai to San Antonio. Sea freight Q3 2026: 20ft FCL USD 2,500-3,200, 40GP USD 2,800-3,500, 40HQ USD 3,000-4,500.
5. What is the SoC requirement for shipping BESS to Chile?
For air: ≤30% under IATA DGR 67th Edition (mandatory from 1 January 2026). For sea: no specific SoC limit under IMDG Code for UN3536, but most manufacturers ship at 30-50%. Note: IMDG Code Amendment 42-24 (mandatory from 1 January 2026) changes the stowage category for UN3536 from Category A to Category D (on-deck only) and adds stowage codes SW1 (protected from sources of heat) and SW2 (clear of living quarters). We pre-condition to 28% for air, 30-50% for sea, at our Shenzhen facility.
6. What are the main BESS ports in Chile?
San Antonio (~35-40% of sea volume, the largest container port in Chile, the gateway to Santiago Metropolitan Region and central Chile), Valparaiso (~30-35%, the gateway to Valparaiso Region and the central coast), Antofagasta (~5-10%, the mining port, the gateway to Antofagasta Region, Atacama Region, and the mining projects of BHP, Codelco, SQM, Albemarle), San Vicente (~5-10%, the southern port, the gateway to Bio Bio Region and southern Chile), Iquique (~5%, the northern port, the gateway to Tarapacá Region). For mining BESS in Antofagasta Region (BHP Escondida + Spence, Codelco Chuquicamata), use Antofagasta. For utility-scale BESS in Santiago Metropolitan Region or central Chile (Grenergy Oasis de Atacama, Sonnedix Librillo, Acciona El Romero), use San Antonio or Valparaiso.
7. What's the biggest hidden cost?
The Form F (China-Chile FTA) missing or filed late is the most common first-timer trap. A missing Form F triggers the 6% MFN default duty (USD 72,000 on a USD 1.2M BESS) and adds 3-7 days of demurrage. The Form F must be filed before the cargo is loaded at the Chinese port, not after arrival at San Antonio or Valparaiso. The second hidden cost is the SEC electrical safety certificate: a missing or sample-mismatched SEC certificate triggers a 4-8 week hold and costs CLP 1,500,000-4,000,000 (USD 1,600-4,300) in re-registration fees. The third hidden cost is the CEN grid connection application sequencing: the application can take 12-24 weeks, and a delayed application delays the project COD by 12-24 weeks. The fourth hidden cost is the Chilean port strike risk (Sindicato de Estibadores), which can add 3-7 days of delay during contract negotiations.
8. What is the Sonnedix Librillo project, and what does it mean for BESS exporters?
Sonnedix Librillo 643.8 MWh BESS project (Antofagasta Region, Chile) is one of the largest single BESS projects in Chile and a critical 2026 reference for Chinese BESS exporters. The project is being developed by Sonnedix (UK-headquartered IPP, owned by JP Morgan), with first COD expected in 2026-2027. The BESS component is 643.8 MWh, using Sungrow PowerTitan 2.0 systems (5 MWh / 2.5 MW per unit). The project is located in the Antofagasta Region, near the Atacama Desert. The project requires SEC electrical safety certificate, Form F (China-Chile FTA 0% duty), and CEN grid connection application. The project is the most important reference project for any first-time Chinese BESS exporter to Chile.
9. What is the Grenergy Oasis de Atacama, and what does it mean for BESS exporters?
Grenergy Oasis de Atacama 7 GWh BESS complex (Atacama Region, Chile) is the largest BESS complex in Latin America and the most important 2026-2030 reference for Chinese BESS exporters. The Oasis de Atacama is being developed by Grenergy (Spain-headquartered IPP) in phases. The current installed capacity is approximately 1.5+ GWh, and the planned total is 7 GWh. The first phase (Gran Teno 241 MW solar + 939 MWh storage, Planchón 108 MW solar + 402 MWh storage, Tamango 49 MW solar + 168 MWh storage, Monte Águila 34 MW solar + 1.1 GWh storage) is being supplied by BYD with 468 MC Cube-T BESS units (2.6 GWh total). The Elena BESS (3.5 GWh, plans to expand to 7 GWh) signed a 1 TWh night-time PPA in June 2026 with a 15-year term. The Oasis de Atacama is the most important reference project for any first-time Chinese BESS exporter to Chile, and requires SEC electrical safety certificate, Form F, and CEN grid connection application.
10. What is the BHP Escondida + Spence project, and what does it mean for mining BESS?
BHP Escondida + Spence 195 MW solar + 960 MWh BESS project (Antofagasta Region, Chile) is the largest mining BESS project in the world and the most important mining BESS reference. The project is being developed by BHP (the world's largest mining company, Australian-British), with first COD expected in 2026-2027. The BESS component is 960 MWh, supplied by Sungrow, paired with 195 MW of solar PV. The project is located at the BHP Escondida and Spence copper mines in the Antofagasta Region, the world's largest copper mine. The project is the most important mining BESS reference for any first-time Chinese BESS exporter to Chile's mining sector, and requires SEC electrical safety certificate, Form F, and off-grid microgrid certification (the BESS connects directly to the mine's microgrid, no CEN grid connection required).
