Customs Clearance for Shipping Lithium Batteries

Define both customs handoffs before the cargo moves.

Lithium battery export customs clearance in China and import clearance at destination are related stages with different parties and responsibilities. The quotation should state what BAT coordinates and what remains with the exporter, importer, customs representative or another appointed party.

China export handoff

Confirm the exporter and supplier details, commercial invoice, packing list, cargo description, quantity, weight, value, origin, proposed HS classification and the transport information required for the selected route.

Destination import handoff

Confirm the importer or consignee, customs representative, tax registration, declaration basis, product eligibility, licences or registrations where applicable, duty and tax responsibility, and the release-to-delivery arrangement.

Quotation boundary

A freight quotation does not override a customs decision. It should identify the included origin work, international movement, import-clearance coordination, duty or tax arrangement, destination handling and delivery scope.

For ordinary commercial cargo and broader export/import coordination, see our customs clearance service from China.

Classify the physical shipment before preparing the declaration.

The words “lithium battery” are not a complete cargo description. Customs and transport parties need to understand what is moving, how it is configured and how that description relates to the commercial documents.

Common lithium battery transport entries include UN3480 and UN3481 for lithium-ion batteries, and UN3090 and UN3091 for lithium metal batteries. Other entries may apply to vehicles, systems or different battery chemistries. The correct entry depends on the actual chemistry and configuration. Do not select a UN number or customs classification from a similar product page without checking the shipment itself.

For a broader preparation overview, read how to ship lithium-ion batteries internationally.

Build one consistent evidence pack—not a pile of unrelated certificates.

The exact document set varies by cargo, mode, route and destination. Some records support transport acceptance, some support customs declaration, and others relate to product-market obligations. One document does not replace all the others.

The test summary includes identifiers such as the manufacturer, test laboratory, report number, test date, battery description, model and test results. It is not a customs release certificate and BAT does not issue it. A full laboratory report and a test summary are also not the same document. The relevant party may request one or both depending on the shipment and process.

Provide package construction, quantities, net battery weight where relevant, marks and labels, photographs, and any mode-specific shipper or carrier documents requested for the chosen service.

Important: the presence of a UN 38.3 test summary, SDS or transport label does not by itself confirm the HS code, customs value, import eligibility or destination product compliance.

Use battery test information for the right purpose.

UN 38.3 sits within the United Nations transport testing framework for cells and batteries. The test summary helps identify the tested battery type and the underlying report. It should be consistent with the manufacturer, model, chemistry, rating and physical cargo.

During a shipment review, check:

1. whether the manufacturer and model match the product being shipped;
2. whether the battery description and rating match the specification;
3. whether the test report number and date are present in the summary;
4. whether the configuration in the transport documents matches the packed cargo; and
5. whether the carrier, declaration party or destination representative requests additional evidence.

Do not describe UN 38.3 as a licence issued by BAT, an automatic customs approval or a guarantee of carrier acceptance.

Treat the customs code as a product decision—not a battery shortcut.

The international Harmonized System provides a shared six-digit foundation, while customs territories may add further digits and measures. The correct classification can depend on whether the shipment is a cell, battery, component, complete device, vehicle or another product.

A code used for a standalone battery may not be correct for equipment containing that battery. The classification also affects duties, taxes, import restrictions, statistical reporting and possible licensing requirements.

Before declaration, align:

• the detailed product description;
• composition, function and intended use;
• battery configuration;
• invoice and transaction value;
• country of origin;
• Incoterm and freight/insurance treatment where relevant;
• any prior ruling or importer instruction; and
• the destination tariff schedule.

BAT can coordinate the information handoff, but the responsible declarant or importer must support the proposed classification, and the customs authority may review or determine the accepted classification and treatment. Where classification is uncertain, the importer should seek advice or a binding decision from the relevant customs authority before dispatch.

Match the customs file to the selected transport mode.

Customs information should not be prepared in isolation from the booking. The physical packing, route and transport documents must support the same cargo description.

Air freight

Air shipments are reviewed against the applicable ICAO/IATA provisions and operator variations. Battery chemistry, configuration, Watt-hour rating, state of charge where applicable, package limits, packing instruction, marks, labels and shipper documentation may affect acceptance.

For China-origin air execution, see lithium battery shipping by air from China.

Sea freight

Packaged dangerous goods carried by sea are reviewed under the applicable IMDG Code provisions, together with carrier, port, terminal, consolidation and destination conditions. FCL and LCL options require different operational handoffs and must be confirmed for the actual cargo and route.

For China-origin ocean execution, see lithium battery shipping by sea from China.

Transport acceptance and customs release remain separate decisions. A customs entry cannot make non-accepted cargo eligible for a carrier, and a confirmed booking cannot make an incomplete import declaration acceptable to customs.

Avoid universal country checklists.

Battery rules differ by destination and by product category. A standalone industrial cell, consumer power bank, e-bike, medical device, vehicle battery and complete energy-storage system may not share the same market-access obligations.

Before shipping, the importer or an appointed specialist should identify:

• whether the product may be imported and sold in the destination;
• the correct importer and customs representative;
• tariff classification and customs valuation method;
• required product registrations, markings or conformity records;
• environmental, producer-responsibility or recycling obligations;
• licence, permit or agency controls for the product’s intended use; and
• record-retention and labelling responsibilities after release.

Do not assume that CE, UKCA, CCC, KC, WEEE, REACH or another marking or programme applies to every battery. Confirm the actual product and jurisdiction. Requirements for Great Britain and Northern Ireland can also differ, just as requirements within and outside the European Union differ.

Resolve inconsistencies before they become border questions.

Generic cargo description

The invoice says “electronic parts,” while the transport documents and physical cargo identify standalone lithium-ion batteries.

Model mismatch

The battery model on the specification, test summary, SDS, labels or product differs from the model being shipped.

Quantity or weight mismatch

The invoice, packing list, transport document and physical pieces do not agree.

Unconfirmed importer

The consignee is named, but no eligible importer, tax registration or customs representative has been confirmed.

Unsupported tariff code

A code was copied from another product or country without checking the actual item and destination schedule.

Missing product requirement

The transport file is complete, but a destination product registration, licence or other market obligation has not been addressed.

Undisclosed condition

Used, prototype, returned, damaged, defective, recalled or end-of-life batteries are presented as ordinary new commercial cargo.

Complete information cannot guarantee that customs will not inspect or request additional documents. It can help the responsible parties answer questions with a consistent shipment record.

Turn shipment facts into a defined customs handoff.

Clear coordination without universal promises.

BAT Logistics can review supplied shipment information and coordinate relevant freight, declaration and destination parties for an eligible route. The exact scope is confirmed in the quotation.

BAT does not automatically act as the exporter, importer of record, customs authority, testing laboratory, certification body or customs broker in every country. We do not issue UN 38.3 test reports or summaries, SDS documents, product certifications, licences or permits.

We cannot guarantee carrier acceptance, a particular tariff classification, duty rate, no inspection, customs release, a fixed clearance time or final regulatory approval. Those outcomes depend on shipment details and the relevant operating parties and authorities.

If a duty-paid structure is being considered, review the separate DDP battery shipping scope. DDP must still define the importer, tax, customs and delivery responsibilities for the destination.

Send the facts needed for a battery customs review.
