Shipping Batteries from China: The Complete 2026 Guide
Last updated: June 17, 2026 · Reading time: 18 minutes · Author: Bill Guo, Sales Manager, BAT Logistics
From the BAT desk: This isn’t a regulation manual. It’s the playbook we’ve built over 6 years and 6,500+ battery shipments from China. The rules are the floor — what we’re sharing here is how to walk that floor without tripping.
Table of Contents
Want to ship lithium batteries from China? Three things you absolutely have to understand:
- The three rules that govern everything: Air shipments follow IATA DGR 67th Edition (2026.1.1 in effect). Sea shipments follow IMDG Code 42-24. Then there’s your destination country’s import regulations on top of that.
- The three documents you cannot ship without: UN38.3 test report (proves your battery is safe), MSDS/SDS (the battery’s “chemical ID card”), and the Dangerous Goods Declaration (DGD).
- The 2026 mandatory change: Battery state-of-charge (SoC) must be ≤30% for cargo aircraft. This used to be a recommendation. Starting January 1, 2026, it’s enforced — and airlines will reject anything above that line.
Master those three, and you’ve covered 80% of what you need to know to ship batteries from China in 2026.
What's New in 2026 (And Why It Matters)
2026 is a banner year for battery shipping regulations. Four changes are already affecting how you pack, document, and book your shipments:
1. IATA DGR 67th Edition took effect January 1, 2026. The biggest change: SoC 30% moved from “recommended” to “mandatory” for cargo aircraft. Carriers like Cathay, China Airlines, and PAL Cargo can — and will — reject shipments above 30%.
2. IMDG Code 42-24 has been active since January 1, 2024. The marine rules settled in two years ago, but a lot of shippers are still catching up. The main change: UN38.3 is now mandatory at the booking stage, not just at the documentation stage.
3. UN3551 — Sodium-ion batteries finally have a UN number. This is the first year sodium-ion is being shipped in real commercial volumes. CATL and BYD are leading production. The rules look similar to lithium-ion but the UN number is different — get this wrong and you’ll be rejected.
4. EU 2023/1542 Battery Regulation is now fully enforced. If you ship to the EU, you’ll need a carbon footprint declaration. A digital battery passport is coming in 2027.
In short: the rules are tightening, the documentation burden is increasing, and the operators (airlines, shipping lines, customs) are enforcing more strictly. The good news? Most of it boils down to a few key decisions. Let’s walk through them.
Why Shippers Trust BAT for Battery Freight
In the last six years, we’ve moved 6,500+ battery shipments from China. No major incidents. A few scrapes — call it a learning tuition.
Here’s what that 6,500 has taught us, and what we bring to your shipment:
Our team holds IATA DGR Category 6 certification. That’s the highest level of dangerous goods training in the air freight world — think of it as a PhD-level qualification for shipping hazardous materials. Everyone on the desk, from sales to operations, has it.
We have direct relationships with 6 airlines that actually accept batteries. Not every carrier does. The carriers that matter: Philippine Airlines Cargo, Cathay Cargo, China Airlines, China Eastern, China Southern, and Xiamen Airlines. These are the operators that have invested in dangerous goods handling — they have the trained staff, the right equipment, and the procedures to move your battery shipment safely.
We work across 6 regulatory bodies: CAAC (China’s civil aviation authority), IATA, IMDG/IMO (the maritime side), FAA (US), and the customs agencies of every destination country we serve. Knowing who sets the rules, who enforces them, and what they actually check is half the battle.
We’ve seen the rejections. 8 common ones, actually — we’ll get to those in section 8. We’ve also seen the rescues. The pattern is the same: most battery shipment problems are preventable if you know what to look for.
If you’re shipping batteries for the first time — or if you’ve had a bad experience with a previous forwarder who got your shipment rejected at the airport — that’s exactly the kind of problem we’re built to solve.

Forget chemistry class. In practice, every battery shipment you’ll ever make falls into one of four categories. Each has its own “ID number” — the UN classification — and the rules are different for each.
1.Lithium-Ion (Li-ion) — 95% of What You Ship
This is the workhorse. Phones, laptops, power banks, e-bikes, electric vehicles, solar battery storage. Almost everything with a rechargeable battery is lithium-ion.
- UN3480: Battery only, shipped alone (no equipment with it)
- UN3481: Battery packed with or installed in a device
The single most common confusion: which is it — 3480 or 3481? Get this wrong and the airline will reject your shipment. Quick rule: if you ship a power bank by itself, that’s UN3480. If you ship a power bank still in its retail box, that’s UN3481. If you ship a phone with the battery installed, that’s UN3481 (in equipment, Packing Instruction 967).
2.Lithium Metal (Li-metal) — Mostly Button Cells
Primary cells (non-rechargeable). Think watch batteries, hearing aid batteries, some medical device batteries, the small coin-shaped ones.
- UN3090: Battery only
- UN3091: Battery installed in equipment
Lithium metal is more strictly regulated than lithium-ion. Smaller quantities, stricter packaging. If your shipment contains button cells, read the rules carefully.
3.Sodium-Ion (Na-ion) — The 2026 Newcomer
First commercial shipments in 2026. CATL’s Na-ion cells are starting to ship for two-wheelers and small energy storage. BYD and HiNa Battery are also in production.
- UN3551: New for 2026
The rules look similar to lithium-ion (Class 9, similar packaging, similar documentation) but the UN number is unique. Don’t assume the same carrier that handles your lithium will handle sodium the same way — confirm before booking.
4.Vehicle Batteries (EVs, E-bikes, Whole Vehicles)
This is the most complex category because there are three different UN numbers depending on the situation:
- UN3556: Whole vehicle powered by a battery (e.g., shipping an electric scooter as a complete unit)
- UN3557: Battery already installed in a vehicle
- UN3558: Battery packed with a vehicle (but not installed in it)
If you’re shipping complete e-bikes, electric scooters, or even small EVs from China, you need to figure out which of these three applies to your shipment. The answer changes the packaging, the documentation, and the carrier approval process.
Pick Your Shipping Mode: Air, Sea, or DDP
The mode you pick changes everything — packaging, documentation, cost, speed. Here’s how to think about it.
1.Air Freight — Fast but Picky
The golden rule: battery state-of-charge must be ≤30%. That 30% number sounds low, but it’s the safety line set by ICAO (International Civil Aviation Organization). Lower SoC = lower risk of thermal runaway = safer cargo hold. The math:
- 100% charged battery: thermal runaway temperature around 80°C
- 30% charged battery: thermal runaway temperature above 150°C
- 30% is the highest safe SoC that the cargo hold can naturally dissipate heat from
There’s also a hidden 100Wh threshold that trips up a lot of new shippers:
- ≤100Wh: Can go on passenger aircraft (PAX). Phone power banks, small replacement batteries, most laptop batteries fall in this range.
- >100Wh: Cargo aircraft only (CAO = Cargo Aircraft Only). E-bike batteries, solar BESS systems, EV battery packs — all cargo aircraft only.
Air freight takes 1-3 days and costs $3.54-9.68/kg depending on destination and urgency. It’s the right choice when you need to move fast and your shipment is under 500kg.
2.Sea Freight — Cheapest for Big Volumes
The unique twist with sea freight: we strongly recommend a reefer (refrigerated) container set to 15-25°C. This isn’t about keeping the battery cold — it’s about keeping the temperature stable so the battery’s SoC doesn’t drift during the 15-30 day voyage. Lithium batteries in a tropical port can hit 50-60°C in a dry container. That’s a thermal runaway waiting to happen.
Required markings:
- Class 9 hazard label (the diamond with the “9” — that’s the “miscellaneous dangerous goods” category, which is where batteries live)
- Lithium Battery Handling Label (the rectangular label that says “do not expose to heat” with a 24-hour emergency contact number)
Sea freight takes 15-30 days and costs $1,800-3,500 per 40HQ reefer container. It’s the right choice for anything over 500kg or any shipment that’s not time-critical.
3.DDP Door-to-Door — Easiest for First-Timers
DDP = Delivered Duty Paid. One price covers everything: freight, customs duties, VAT/GST, and final delivery to the consignee’s door. $90-140/CBM by sea or $5-9.68/kg by air, 10-15 days typically.
If you’ve never shipped batteries internationally before, DDP is the safest way to start. We handle all the customs paperwork, duty calculations, destination VAT registration if needed. You get one invoice, one tracking number, one point of contact. It’s more expensive than DDU, but predictability is worth it.
The 8 Documents You Need (And Why Each One Exists)
Eight documents sounds like a lot. But each one exists for a specific reason, and each one is checked at a specific stage. Here’s the breakdown:
① UN38.3 Test Report + Test Summary
The Test Report is the full 8-test battery safety report (we’ll cover the 8 tests in section 5). The Test Summary is a newer, simplified 7-field version that carriers started requiring in 2019-2020. Both are needed. Reports are valid 3-5 years depending on the testing lab. Critical point: the model number on the report must exactly match the model number on the battery you’re shipping. A single digit difference means the report is invalid for your shipment.
② MSDS/SDS (Material Safety Data Sheet)
The battery’s “chemical ID card.” 16 sections covering chemical composition, first aid measures, fire-fighting measures, accidental release measures, handling and storage, exposure controls, and so on. Must include UN number, Class 9 designation, flash point, and emergency response procedures. Both English and Chinese versions are typically required.
③ DGD (Dangerous Goods Declaration)
The formal declaration that your shipment contains dangerous goods. 27 mandatory fields including UN number, proper shipping name, hazard class, packing group, packing instruction (PI 965 or whatever applies), quantity, weight, shipper, consignee, and 24-hour emergency contact. Must be signed by the shipper (or their authorized agent). This is the document that, if wrong, will get your shipment rejected fastest.
④ Class 9 Hazard Label
The diamond-shaped “Class 9 Miscellaneous Dangerous Goods” label. Must be at least 100mm × 100mm. Black and white with the number “9” underlined, on an orange background. Goes on every package, same side.
⑤ Lithium Battery Handling Label
The rectangular label that says “Lithium battery — do not expose to heat” with a 24-hour emergency contact phone number. At least 120mm × 110mm. Newer requirement (2020+) but now universal.
⑥ Battery Summary Document
A newer requirement (post-2020) that lists battery model, capacity in Wh, and quantity. Should match the DGD information exactly. Some carriers will request this in addition to the DGD.
⑦ IMO/ICAO Shipper’s Declaration
Depending on whether you’re going by sea or air, you need either the IMO Dangerous Goods Declaration (sea) or the ICAO Shipper’s Declaration (air). The format is different but the purpose is the same: a signed declaration that the shipment complies with the relevant dangerous goods regulations.
⑧ Commercial Invoice + Packing List
Standard customs paperwork. Commercial invoice shows the value of the goods, packing list shows what’s in each carton. Not dangerous-goods-specific, but still required.
UN38.3 Explained: The 8 Tests Your Battery Must Pass
UN38.3 is the United Nations’ “your battery has to survive these 8 trials before we let it on a plane or a ship” rule. Each test simulates something that could realistically happen during transport. Let me walk you through what each test actually does:
T1: Altitude Simulation. The battery goes into a low-pressure chamber simulating the cargo hold of an aircraft at cruising altitude (around 8,000 meters / 26,000 feet). The test checks whether the battery will swell, leak, or rupture under low pressure. No swelling, no leaks, no ruptures = pass.
T2: Thermal Test. The battery is bounced between -40°C and +75°C for 10 cycles, with each temperature held for 6 hours. This simulates the temperature swings between a winter tarmac in Beijing and a summer cargo hold in Singapore. No leakage, no venting, no rupture = pass.
T3: Vibration Test. The battery is vibrated for 3 hours across a frequency range that simulates truck, train, and ship transport. No mass loss, no leakage, no rupture, no voltage drop below threshold = pass.
T4: Shock Test. The battery is subjected to 18 different shock pulses simulating the jolts of transport handling — drops from forklifts, sudden stops, impacts during loading. No rupture, no fire, no voltage drop below threshold = pass.
T5: External Short Circuit. The battery terminals are deliberately short-circuited (positive to negative through a low-resistance connection) for at least 1 hour. The test passes if the battery doesn’t catch fire, doesn’t vent, doesn’t rupture, and the case temperature doesn’t exceed 150°C.
T6: Impact / Crush. A 9.1kg weight is dropped from 61cm onto the battery, OR a hydraulic press applies 13kN of force (which is roughly equivalent to a small car’s weight on a single point). Tests physical damage scenarios. No fire, no explosion = pass.
T7: Overcharge. The battery is charged to 200% of its rated capacity and held there for 24 hours. Tests what happens if the charging system fails. No fire, no explosion = pass.
T8: Forced Discharge. The battery is discharged below its rated minimum voltage for an extended period. Tests the reverse direction. No fire, no explosion = pass.
Pass all 8 + get a formal test report from a certified lab, and your battery model is cleared for international transport. The test report typically costs USD 3,000-15,000 per battery model and takes 4-6 weeks.

Five destination countries account for the majority of battery shipments from China. Each has its own quirks:
USA — $7B+ Lithium Import Market in 2024
The single largest market for Chinese lithium batteries. E-bikes, power tools, solar BESS, EVs — if it’s battery-powered, it ends up in the US. Main entry ports: Los Angeles / Long Beach, New York / New Jersey, Savannah, Houston. Top retailers carrying Chinese-battery products: Amazon, Best Buy, Home Depot, Walmart.
US-specific requirements: UL2054 (household batteries), UL1973 (stationary BESS), UL1642 (cells), FCC Part 15 (EMC), plus the standard UN38.3 + 49 CFR 173.185.
UK — Post-Brexit CE/UKCA
The UK has its own regulatory system after Brexit. UKCA marking is now required alongside CE. UK VAT is 20%. Main entry ports: Felixstowe, London Gateway, Liverpool. HMRC is the customs authority, and you need an EORI number to import.
EU — 2026 Battery Regulation (EU 2023/1542)
The EU’s 2023/1542 Battery Regulation is now fully in effect. Key requirements: carbon footprint declaration, recycled content documentation, and (coming 2027) the digital battery passport. VAT varies by country: 19% in Germany, 20% in France, 21% in the Netherlands. CE marking is mandatory. Top entry ports: Rotterdam, Hamburg, Antwerp.
Australia — Clean Energy Target
Australia is investing heavily in renewable energy and household battery storage. Clean Energy Target aims for 50% renewables by 2040, which means massive demand for solar BESS. Main entry ports: Sydney (Port Botany), Melbourne, Brisbane. AU GST is 10%. RCM marking is required for electrical products.
Canada — $1B+ Battery Market
Smaller than the US but growing fast. CBSA (Canada Border Services Agency) is the customs authority. GST is 5% federally, plus provincial sales tax (HST up to 15% in some provinces). Main entry ports: Vancouver, Montreal, Halifax. New battery regulation SOR/2024-103 was issued in 2024.
The 4 Products We Move Most Often

Complex DG
4. EV Battery Packs
Large-scale 50kWh to 100kWh automotive packs. Highly complex classification requiring custom carrier approvals and full FCL tracking.
UN Codes: UN 3556 / 3557 / 3558
Logistics: Dedicated FCL Sea / Reefer
Four product categories account for the majority of our battery shipments. Each has its own shipping pattern.
E-Bike Batteries — Most Common
160Wh to 1,000Wh per pack. Most e-bike batteries are 48V 15-20Ah (720-960Wh), which puts them firmly in the “cargo aircraft only / reefer sea freight” category. Typical batch size: 100-500kg. Typical transit: 5-15 days air, 25-35 days sea.
Top markets: Netherlands (€1.5B+ e-bike market), Germany (€1.2B+), USA ($1.5B+), UK (£500M+), France (€700M+).
Solar BESS (Battery Energy Storage Systems) — Fastest Growing
10kWh to 1MWh per system. A single 40HQ reefer container can fit one 1MWh system or multiple smaller units. Demand is driven by the renewable energy transition, household backup power, and off-grid applications. Special handling: reefer temperature monitoring throughout transit, vibration control, and a separate BMMS (Battery Management Monitoring System) check before shipping.
Power Banks (Portable Chargers) — Highest Volume, Smallest Margins
5,000mAh to 50,000mAh. The classic e-commerce product. Small parcels, high volume, low individual weight. Most power banks are 18.5Wh to 185Wh (5,000-50,000mAh at 3.7V). Anything over 100Wh needs cargo aircraft only. Power banks are a high-volume B2C e-commerce play — Amazon FBA, Lazada, Shopee, TikTok Shop.
EV Battery Packs — Most Complex
50kWh to 100kWh per pack. Special handling required: dedicated 40HQ reefer containers, full container load (FCL) only, temperature monitoring throughout, and special carrier approval. UN3556, UN3557, or UN3558 depending on the situation. Transit: 25-40 days sea, 5-10 days air (very expensive, usually only for samples or urgent replacements).
The 8 Mistakes That Get Your Shipment Rejected
In our 6,500+ shipments, these are the 8 most common reasons a battery shipment gets rejected at the airport or port. The first 3 account for about 70% of rejections.
1. Wrong UN number on the DGD. UN3480 (battery only) vs UN3481 (battery in/with equipment) — a one-digit difference that completely changes the rules. Mix them up and your shipment is rejected on the spot. The rule of thumb: if the battery is installed in a device or in its retail packaging with the device, it’s UN3481. If it’s bare batteries in a box, it’s UN3480.
2. UN38.3 report expired or missing. UN38.3 reports are valid 3-5 years depending on the lab. Battery manufacturers forget to renew. Airlines check the report date at booking. Expired report = no booking.
3. State of charge above 30% on air shipments. This is the 2026 mandatory rule. Factory default is 100%. Without a discharge service, your shipment is going to be rejected. The fix: have a SoC verification done 7 days before shipment, keep the certificate with the shipping documents.
4. DGD not filled out or filled out incorrectly. Most common with new shippers who don’t realize dangerous goods paperwork is fundamentally different from regular cargo paperwork. UN number wrong, quantity wrong, Wh number wrong, missing shipper signature — any of these can trigger a rejection.
5. Class 9 hazard label missing or misplaced. Every package needs the Class 9 diamond. Some shippers put it on the bottom of the box, or only on some of the boxes, or use a label that’s too small. All of these will be caught by the carrier or customs.
6. No operator approval obtained in advance. Cargo aircraft (CAO) shipments need 48-72 hours of pre-approval from the airline. Same for some shipping lines. Show up at the warehouse with a booking and no pre-approval, and the carrier will turn you away.
7. Damaged outer packaging shipped anyway. The 1.2m drop test is done at the lab, not at your warehouse. If the box gets banged up by a forklift at the warehouse, it’s no longer compliant. Repack. Don’t ship a damaged box.
8. Lithium and non-dangerous goods mixed in the same outer package. Battery + charger + cable in one box might seem convenient, but if the non-battery items are declared as “not DG,” the whole shipment is now mis-declared. Batteries need their own packaging, their own DGD, their own declaration.
What It Actually Costs (2026 Real Numbers)
Here’s what real shipments cost in 2026. These are actual numbers from our recent bookings, not estimates.
Air Freight Costs (per kg, all-in including DGD handling)
Destination | 100-500kg | 500-2,000kg | 2,000+kg |
|---|---|---|---|
USA (LAX/JFK/ORD) | $6.50-9.68 | $5.50-7.50 | $4.50-6.50 |
UK (LHR/MAN) | $7.00-11.00 | $6.00-8.50 | $5.00-7.50 |
EU (FRA/AMS/CDG) | $7.00-11.00 | $6.00-8.50 | $5.00-7.50 |
Australia (SYD/MEL) | $8.00-12.00 | $7.00-10.00 | $6.00-8.50 |
Canada (YYZ/YVR) | $7.00-11.00 | $6.00-8.50 | $5.00-7.50 |
Sea Freight Costs (per 40HQ Reefer Container, FCL all-in)
Destination | Transit | Cost (USD) | Reefer Surcharge |
|---|---|---|---|
USA West Coast (LA/LB) | 16-22 days | $2,200-3,800 | $400-700 |
USA East Coast (NYC/SAV) | 28-35 days | $2,800-4,200 | $500-800 |
UK (Felixstowe) | 28-35 days | $2,500-4,000 | $500-800 |
EU (Rotterdam) | 28-35 days | $2,500-4,000 | $500-800 |
EU (Hamburg) | 30-38 days | $2,500-4,200 | $500-800 |
Australia (Sydney) | 18-25 days | $2,800-4,000 | $400-700 |
Canada (Vancouver) | 22-30 days | $2,500-3,800 | $400-700 |
DDP Door-to-Door Costs (USD per CBM, sea)
Destination | 1-15 CBM | 15-50 CBM | 50+ CBM |
|---|---|---|---|
USA | $200-350 | $160-260 | $130-200 |
UK | $250-400 | $200-300 | $160-240 |
EU | $250-400 | $200-300 | $160-240 |
Australia | $300-450 | $250-350 | $200-300 |
Canada | $250-400 | $200-300 | $160-240 |
Cost-saving tip: LCL (less than container load) is more expensive per CBM than FCL. The breakeven is usually around 15-20 CBM — below that, the per-unit cost of LCL starts to make sense. Above that, switch to FCL.
FAQ — The 15 Questions We Get Every Week
Q1: I'm a first-time battery shipper. What's the single most important thing to get right?
Your UN classification (UN3480, UN3481, UN3090, etc.). If this is wrong, everything else falls apart. Talk to your battery manufacturer first to confirm whether you're shipping bare batteries or batteries installed in equipment.
Q2: My battery is 50Wh. Can it go on a passenger aircraft?
Yes. Under Packing Instruction 967, lithium-ion batteries ≤100Wh that are installed in equipment can go on passenger aircraft. You still need to comply with SoC 30% and the standard documentation.
Q3: How do I get SoC 30% verified, and who issues the certificate?
Three options: (1) Physical discharge at a certified lab (most accurate); (2) Pre-discharge at the factory + a SoC certificate; (3) Hire a freight forwarder with in-house SoC verification. The lab certificate typically costs USD 800-1,500 for 50-200 batteries. Common labs: CTC, CQC, TUV (all in Shenzhen/Guangzhou).
Q4: How long is a UN38.3 report valid?
3-5 years depending on the lab and the standard. Reports issued in 2024 and later are usually 3 years. Check with your testing lab for the exact validity.
Q5: Can I use a foam box instead of a UN 4G fiberboard box?
No. UN 4G is a specific certification for fiberboard boxes that pass the 1.2m drop test. Foam boxes are not UN-certified and can only be used as inner packaging, not outer.
Q6: How many batteries can I put in one outer box?
Up to 35kg gross weight per box for air (PI 965). For sea, the limit is 30kg. Practical advice: design your packaging for 25kg per box. That gives you margin for the box weight itself and makes handling safer.
Q7: Can I ship batteries by DHL / FedEx / UPS?
Yes, for some UN numbers and some routes. DHL Express has a specific service (DHL IPG) for dangerous goods including lithium batteries. Single-piece limit is 35kg, must be CAO for >100Wh, and price is typically 30-50% higher than regular air freight. But transit is 3-5 days door-to-door, which is fast.
Q8: Do I need cargo insurance?
For shipments over USD 5,000, yes. All-risk marine cargo insurance runs about 0.3-0.5% of cargo value. For air, similar rates. BAT can arrange PICC (China Export & Credit Insurance Corporation) coverage at competitive rates.
Q9: What happens if my shipment is rejected at the destination?
Depends on the terms. DDP (we deliver, you pay): we handle the return. DDU (you deliver, we pay): you handle the return. Return shipping costs run USD 3,000-8,000 depending on the destination port. This is why getting it right the first time is so much cheaper.
Q10: Can I ship damaged or recalled batteries?
Yes, but under Packing Instruction 910 (IMDG sea) or special carrier approval (air). The packaging requirements are significantly more stringent: double-sealed containers, special labeling, carrier pre-approval, and notification of origin and destination customs. Cost is 3-5x normal battery shipping. Most forwarders won't touch this — we do, but it requires a specific process.
Q11: What's the difference between air and sea transit for the same shipment?
Air: 1-3 days, $5-10/kg. Sea: 15-30 days, $1-5/kg. Sea is 60-80% cheaper but 10-20x slower. The decision is usually about urgency vs cost. For 500kg+, sea almost always wins on cost. For under 500kg, air usually wins on speed-to-value.
Q12: Are sodium-ion batteries regulated the same as lithium-ion?
Mostly yes, with one critical difference: the UN number. Sodium-ion uses UN3551, not UN3480/3481. The packaging, Class 9 labeling, and documentation are similar, but the UN number must be correct. New for 2026, so some carriers may not yet have procedures in place — confirm with your carrier before booking.
Q13: What if my battery doesn't have a UN38.3 report?
You cannot legally ship it internationally. The options are: (1) Send samples to a UN38.3 testing lab (4-6 weeks, USD 3,000-15,000), or (2) Find a battery supplier who already has UN38.3 certification for the same cell type. Don't try to ship without it — the carrier will reject it at booking.
Q14: Can I ship a battery with the equipment together?
Yes, and it's actually easier than shipping batteries alone. Packing Instruction 966 (packed with equipment) or 967 (in equipment) typically allows passenger aircraft for ≤100Wh, has fewer documentation requirements, and the packaging can be simpler. If your product is a complete device with a battery inside (a laptop, a phone, a power tool), this is the easiest way to ship.
Q15: What's the most common reason a first-time battery shipper's first shipment gets rejected?
Wrong UN number on the DGD. Specifically, declaring UN3480 when it should be UN3481 (or vice versa). This one mistake will get your shipment stopped at the airline acceptance counter. The second most common: forgetting to discharge the battery to 30% before air shipment. The third: not having a current UN38.3 report.
How to Choose a Battery Freight Forwarder (And What to Ask Them)
Not every freight forwarder is set up to handle batteries. Some will say yes and then bounce your shipment at the airport. Here’s what to look for, and the 6 questions that separate the real battery forwarders from the pretenders.
The 6 Questions to Ask Before Booking
1. What’s your IATA DGR certification level? The answer should be Category 6 — the highest level. Category 4 can do limited battery shipments. Anything below Category 4 is not qualified.
2. How many battery shipments did you handle in the last 12 months? A serious battery forwarder does hundreds. We do 1,000+. If the answer is “a few dozen” or “we’ve done some,” keep looking.
3. Which airlines do you have direct relationships with for CAO cargo? The right answer includes at least 2-3 of: Cathay, China Airlines, China Eastern, China Southern, PAL Cargo, Xiamen Airlines. If they say “we can book any airline,” that means they don’t have direct relationships and you’ll pay more.
4. Can you handle the SoC 30% verification in-house, or do I need to find a lab separately? A good forwarder has a SoC verification partner. The best ones have it in-house. We have a 3-lab partner network in Shenzhen/Guangzhou with 2-3 day turnaround.
5. What’s your rejection rate? Ask directly. If the answer is “I don’t track that,” that’s a red flag. Our rejection rate is under 0.5% — and most of those are force majeure (weather, COVID-era capacity cuts), not documentation errors.
6. Can you give me 2-3 references from battery shippers? A serious forwarder can. We have case studies across Anker alternatives, drone manufacturers, e-bike brands, solar BESS integrators, and more. Ask to see them.
Red Flags to Watch For
- “Batteries are easy, we can handle them.” No, they’re not. If someone tells you that, they haven’t done many.
- “We can ship anything by air, no problem.” The 30% SoC rule and the 100Wh threshold make this statement nonsense.
- “You don’t need UN38.3 for [some product type].” You almost always do.
- “We’ll figure out the documentation as we go.” No. Documentation is pre-flight, not improvisation.
Green Flags to Look For
- They ask about your UN number, Wh rating, and destination BEFORE quoting
- They mention SoC 30% without being prompted
- They have a 24-hour emergency contact (not just office hours)
- They proactively flag risks (e.g., “your battery is 156Wh, that’s CAO only — budget accordingly”)
- They send you a documentation checklist before you book
How BAT Works With You (Our Process)
01
Step 1: Quote Request & Strategy (Day 1)
You provide the battery specs (UN number, Wh, weight). Within 4 business hours, you receive 2-3 tailored multi-modal shipping options with transparent all-in pricing.
02
Step 2: Document Pre-Audit (Day 2-3)
We review your UN38.3 test summaries, MSDS, and factory packing lists. We catch and resolve compliance mismatches before your cargo leaves the warehouse.
03
Step 3: Booking & Carrier Approval (Day 3-5)
We lock in space via our block-space agreements. For air cargo (CAO), we initiate the crucial 48-72 hour carrier dangerous goods pre-approval process.
04
Step 4: Inland Pick-up & Export Clear (Day 5-7)
Secure specialized DG trucking from your factory anywhere in China to our hubs (Shenzhen/Guangzhou/Shanghai). We handle export customs declaration seamlessly.
05
Step 5: Transit & Constant Monitoring (Ongoing)
Real-time milestone tracking for air shipments. For ocean freight, we actively monitor reefer container temperatures to guarantee the stable 15-25°C threshold.
06
Step 6: Destination Customs & Bond (Arrival)
We manage final customs clearance through our destination broker network, handling complex classification reviews, bond processing, and VAT/Duty settlement.
07
Step 7: Last-Mile Delivery & Report (Final Day)
Cargo is delivered directly to your door (or Amazon FBA hub) via DG-certified local couriers. You receive a post-delivery performance and variance report.
When you contact us for a battery shipment quote, here’s what happens. We’re sharing this so you know what “good” looks like — whether you end up working with us or another forwarder.
Step 1: Quote Request (Day 1)
You send us: battery type, UN number, Wh per battery, total quantity, weight and dimensions, origin city, destination country and city, preferred transit time.
Response time: Within 4 business hours, you get 2-3 options (e.g., “Air Standard 5-7 days $X/kg” and “Air Express 3-5 days $Y/kg” and “Sea Reefer 25-30 days $Z/CBM”).
Step 2: Documentation Check (Day 2-3)
Once you confirm the option, we send you a documentation checklist customized to your shipment:
- UN38.3 report (current, model match)
- MSDS/SDS (English + Chinese)
- Battery Summary Document
- Commercial invoice + packing list
- 24-hour emergency contact
- SoC verification (if air)
- Carrier approval timeline
We review your documents and flag issues before the cargo even leaves your factory.
Step 3: Booking + Carrier Approval (Day 3-5)
We book the cargo with the appropriate carrier, submit the dangerous goods declaration, and initiate the carrier pre-approval process (48-72 hours for CAO).
Step 4: Pickup + Export (Day 5-7)
We arrange factory pickup (anywhere in China), transport to the airport/port, export customs clearance, and loading.
Step 5: Transit + Tracking (Day 7-30 depending on mode)
You get real-time tracking updates. For sea, we monitor the reefer temperature throughout the voyage. For air, we monitor the carrier’s milestone updates.
Step 6: Destination + Delivery (Day 8-35 depending on mode)
Destination customs clearance, duty/VAT payment, and final delivery. For DDP, this is all on us. For DDU, we hand off to your nominated broker.
Step 7: Post-Delivery (Ongoing)
We send you a post-shipment report with: actual transit time, cost variance vs quote, any issues encountered, and recommendations for next time. If something went wrong, we tell you upfront and explain how we’ll prevent it next time.
