Lithium Battery Transport — Air and Sea Shipping Checks
Interlink編集部What Is Lithium Battery Transportation?
Lithium battery transportation involves the handling of cargo containing lithium-ion or lithium metal batteries according to hazardous materials regulations for air and maritime transport.
Lithium batteries are used in many products, including smartphones, laptops, mobile batteries, power tools, medical devices, measurement instruments, automotive equipment, storage batteries, and electric bicycle components.
In freight forwarder operations, it is important to verify not only whether batteries are included but also the battery type, whether they are transported alone, packed with equipment, or built into equipment, rated watt-hour capacity, lithium content, quantity, packaging condition, mode of transport, and acceptance conditions of airlines, shipping lines, and CFS.
Lithium battery cargo may appear as ordinary electronic devices or parts but could require hazardous materials handling confirmation. Especially in air transport, these shipments often face restrictions such as non-acceptance, cargo aircraft only, additional documentation, labeling and marking requirements, and packaging conditions.

Overview of Lithium Battery Transportation
Lithium batteries pose risks such as heat generation, fire, short-circuiting, and fire hazards in case of damage, and therefore they may be classified as dangerous goods in international transport.
In air transport, safety restrictions are particularly strict. It is necessary to verify whether the battery can be carried on passenger aircraft, if cargo-only aircraft must be used, packaging instructions, markings, labels, and whether a dangerous goods declaration is required.
In maritime transport, lithium batteries may also be handled as dangerous goods under the IMDG Code. This requires checks on container stuffing, mixed loading, CFS in-gate, shipping line bookings, dangerous goods manifest, markings, and stowage conditions.
An important point in lithium battery transport is not simply whether batteries are present. The UN number, packaging, markings, documentation, and acceptance depend on the battery type, whether batteries are shipped alone, with equipment, or installed within equipment.
How to Verify the Shipper’s Claim of "Not Dangerous Goods"
In lithium battery shipments, shippers may state, "This is not a dangerous good," "The batteries are only installed in equipment," or "The quantity is small."
However, for cargo containing lithium batteries, shipping should not proceed based solely on this explanation. Freight forwarders need to cross-check documentation against the actual cargo.
| Step | What to Verify | Guidance for Decision | Common Points of Delay |
|---|---|---|---|
| 1. Confirm presence of batteries | Check if the product contains lithium batteries, spare or replacement batteries, or battery packs. | If batteries are present, treat the cargo as subject to dangerous goods verification. | Battery presence may not be clear from invoice item descriptions alone. |
| 2. Confirm battery type | Determine whether the batteries are lithium-ion or lithium metal type. | The applicable UN number and required documentation will vary. | Shippers may only say "lithium battery" without specifying the type. |
| 3. Confirm battery configuration | Verify if the batteries are packed alone, with equipment, or installed within equipment. | Shipping conditions differ even for the same battery based on its configuration. | It is easy to confuse batteries packed with equipment and batteries built into equipment. |
| 4. Confirm battery specifications | Check watt-hour rating, lithium content, quantity, weight, and model numbers. | Packing, labeling, and acceptance requirements vary depending on quantity and performance values. | Product specification sheets may lack sufficient battery-specific details. |
| 5. Verify UN38.3-related documentation | Review UN38.3 test summaries, product specifications, and manufacturer materials. | Confirm that the necessary transport testing requirements are met. | Document model numbers may not match the actual cargo. |
| 6. Confirm cargo is not abnormal | Check that the cargo is not damaged, defective, recalled, returned, or a repair return. | More stringent checks are required compared to regular lithium batteries. | Condition verification often lacks sufficient detail for returned or repaired items. |
| 7. Confirm by mode of transport | Identify whether transport is by air, sea, or courier service. | Check IATA Dangerous Goods Regulations, IMDG Code, and carrier-specific conditions separately. | Decisions for sea transport are sometimes mistakenly applied to air transport. |
| 8. Confirm acceptance conditions | Check conditions set by airlines, shipping lines, CFS, warehouses, and courier companies. | Even if regulations allow, the actual carrier may refuse acceptance. | Acceptance may be halted due to airline or courier company-specific restrictions. |
Major UN Numbers
The following UN numbers are commonly used for lithium battery transport.
| UN Number | Applicable Cargo | Practical Interpretation | Documents and Contacts for Verification |
|---|---|---|---|
| UN3480 | Lithium-ion batteries alone. | Handled as standalone batteries. Special attention should be paid to acceptance conditions for air transport. | Battery specifications, UN38.3 documentation, airlines, shipping lines |
| UN3481 | Lithium-ion batteries packed with, or contained in, equipment. | Confirm packaging, labeling, and documentation requirements depending on whether batteries are packed with equipment or contained in equipment. | Product specifications, packing list, battery documents, photos of actual cargo |
| UN3090 | Lithium metal batteries alone. | Confirm lithium content, quantity, packaging, and acceptance conditions of airlines and shipping lines. | Battery specifications, manufacturer documents, carrier responses |
| UN3091 | Lithium metal batteries packed with, or contained in, equipment. | Confirm relationship to equipment, battery quantity, packaging, and labeling requirements. | Product specifications, packing list, battery documents, photos of actual cargo |
The UN number alone does not determine transport eligibility. It is necessary to verify the battery type, form, watt-hour rating, lithium content, quantity, packaging, transport mode, and carrier conditions in combination.
Differences Between Standalone Batteries, Batteries Included with Equipment, and Batteries Built into Equipment
When transporting lithium batteries, it is crucial to understand in what state the battery is included in the cargo.
| Form | Meaning | Representative Examples | Practical Considerations |
|---|---|---|---|
| Standalone Battery | The battery is shipped as cargo by itself. | Mobile power banks, replacement batteries, spare batteries, battery packs. | Pay special attention to short-circuit prevention, packaging, quantity, and airline acceptance conditions. |
| Batteries Included with Equipment | Batteries are packed in the same package as the equipment but are not installed or built into the equipment. | Including spare batteries in the same box as power tools or replacement batteries with the equipment. | Confirm the relationship between the equipment and batteries, the quantity of batteries, packaging, short-circuit prevention, and labeling requirements. |
| Batteries Built into Equipment | Batteries are transported installed or incorporated within the equipment. | Laptops, smartphones, measuring devices, medical devices, in-vehicle equipment. | Verify whether the battery is protected inside the equipment, misoperation prevention, quantity, and labeling requirements. |
Even when dealing with the same lithium-ion batteries, the UN number and shipping conditions differ depending on whether the batteries are standalone, included with equipment, or built into equipment. If the shipper describes the cargo only as a "battery-containing product," the specific form must be confirmed without fail.
Classification by Battery Type and Form
For lithium battery transport, the battery type and form are confirmed in combination.
| Battery Type | Battery Alone | With Equipment Included | Installed in Equipment |
|---|---|---|---|
| Lithium-ion Battery | UN3480. Confirm watt-hour rating, quantity, charge state, packaging, and airline acceptance conditions. | UN3481. Confirm relationship with equipment, battery quantity, short-circuit prevention, and packaging conditions. | UN3481. Confirm secure installation in equipment, prevention of malfunction, quantity, and necessity of markings and documentation. |
| Lithium Metal Battery | UN3090. Confirm lithium content, quantity, packaging, and acceptance eligibility. | UN3091. Confirm relationship between battery and equipment, quantity, short-circuit prevention, and packaging conditions. | UN3091. Confirm installation status in equipment, battery quantity, and necessity of markings and documentation. |
This table is used for the initial classification in lithium battery transport. Actual acceptance eligibility should be confirmed based on the latest regulations, airline and shipping line conditions, packaging, quantity, and documentation.
Meaning of Rated Watt-Hour, Lithium Content, and Quantity
For lithium battery transport, the rated watt-hour, lithium content, number of units, and weight are critical factors.
Since specific numerical thresholds may change due to regulatory revisions or transport modes, this article organizes the practical confirmation framework rather than fixed numerical values.
| Item to Check | Applicable Battery Type | Practical Significance | Documents to Confirm |
|---|---|---|---|
| Rated Watt-Hour | Lithium-ion batteries. | Packaging, labeling, documentation, and acceptance conditions may differ depending on whether the rating exceeds a certain threshold. | Battery specification sheet, product specifications, manufacturer confirmation documents |
| Lithium Content | Lithium metal batteries. | Key information for deciding battery classification and transport conditions. | Battery specification sheet, manufacturer confirmation documents |
| Number of Batteries | Lithium-ion and lithium metal batteries. | Affects device inclusion, device integration, outer packaging units, and labeling and documentation requirements. | Packing list, packaging details, photos of actual cargo |
| Battery Weight | Individual batteries, battery packs, storage batteries. | Impacts packaging, cargo handling, and acceptance conditions by airlines and shipping lines. | Battery specification sheet, packaging details, weight breakdown |
| Charge State | Mainly lithium-ion batteries in air transport. | May affect airline acceptance conditions and require additional verification. | Manufacturer confirmation letter, shipper confirmation, airline response |
If the shipper does not provide sufficient battery information, the freight forwarder should request product specification sheets, battery specification documents, manufacturer confirmations, UN38.3 test summaries, and similar supporting materials.
Verification of UN38.3
It is crucial that lithium batteries comply with the testing requirements outlined in UN38.3 of the United Nations Manual of Tests and Criteria.
In practice, freight forwarders obtain the UN38.3 test summary, product specifications, safety data sheets, and dangerous goods classification documents from manufacturers or exporters to confirm transport eligibility.
Rather than conducting technical assessments of batteries themselves, freight forwarders should acquire supporting documents from the shipper, manufacturer, or specialized dangerous goods experts. These documents should then be reviewed against acceptance criteria of airlines, shipping lines, and warehouses.
Handling of UN38.3 Documentation by Status
Simply stating that UN38.3-related documents are "available" is insufficient. It is essential to verify whether the documents correspond to the actual cargo in terms of the product, battery model, manufacturer, revision date, and tested items.
| Document Status | Issues | Recommended Actions | Parties to Confirm With |
|---|---|---|---|
| UN38.3 Test Summary Submitted | Needs confirmation that the battery matches the actual cargo. | Verify battery model, manufacturer, product name, and revision date. | Shipper, Manufacturer |
| Test Summary Available but Model Number Differs | Documents may relate to a different battery. | Request resubmission of documents corresponding to the actual battery. | Shipper, Manufacturer, Exporter |
| Only Product Specifications Available, No UN38.3 Documentation | Cannot determine if the testing requirements are met. | Request UN38.3 Test Summary or manufacturer confirmation documents. | Shipper, Manufacturer, Dangerous Goods Specialist |
| Only Overseas Manufacturer’s Documentation Available | Limited personnel able to verify the content. | Request translation, shipper explanation, or manufacturer confirmation as needed. | Shipper, Importer, Manufacturer |
| Documents Are Outdated | Battery specifications or regulatory conditions may have changed. | Check if newer versions of the documents are available. | Shipper, Manufacturer |
| Shipper Unable to Provide Documents | High risk that airlines or shipping lines cannot decide on acceptance. | Confirm with dangerous goods specialists, manufacturers, and exporters, and withhold acceptance decision. | Shipper, Manufacturer, Dangerous Goods Specialist, Carrier |
Damaged, Defective, Recalled, and Returned Lithium Batteries
In lithium battery transport, it is critical to identify whether the shipment involves damaged goods, defective items, recalled products, or repair returns.
If any of these apply, more stringent verification is required compared to regular new or normally used batteries. Acceptance for both air and sea transport may be restricted.
| Cargo Condition | Considerations | Response Approach | Parties and Documents to Confirm |
|---|---|---|---|
| New | Handled as regular lithium battery transport. | Verify UN number, UN38.3 compliance, packaging, quantity, and transport mode-specific conditions. | Shipper, Manufacturer, Carrier |
| Used or Repair Return | Usage history and condition may be unknown. | Check for damage, swelling, overheating, leakage, or modifications. | Shipper, Repair Provider, Manufacturer |
| Damaged | High risk of fire, short circuit, or leakage; may not be handled as regular cargo. | Do not arrange as normal cargo; confirm in advance with airlines, shipping lines, and dangerous goods specialists. | Shipper, Manufacturer, Dangerous Goods Specialist, Carrier |
| Defective | If there are safety-related defects, acceptance restrictions may apply. | Confirm defect details, manufacturer’s position, and transport eligibility. | Manufacturer, Shipper, Dangerous Goods Specialist |
| Recalled | Market recalls or returns may result in a mix of batteries with unknown condition. | Check individual condition, packaging, reason for recall, and transport conditions. | Shipper, Manufacturer, Recall Agent |
| Recalled (Safety-Related) | If recalled for safety reasons, handling may differ from normal transport. | Verify recall reason, hazards, manufacturer instructions, and carrier acceptance. | Manufacturer, Shipper, Airlines, Shipping Lines |
For repair returns and recalled products, do not assume “since it was transportable before, it is acceptable this time.” The condition may have changed, so verify separately from normal cargo.
Differences Between Air Transport and Sea Transport
Lithium battery cargo handling varies between air and sea transport in terms of confirmation points and acceptance conditions.
| Confirmation Item | Air Transport | Sea Transport | Practical Points for Freight Forwarders |
|---|---|---|---|
| Applicable Regulations | Check the IATA Dangerous Goods Regulations. | Check the IMDG Code. | When the mode of transport changes, reconfirm the conditions. |
| Points of Confirmation | Airlines, courier companies, airport warehouses, and dangerous goods specialists. | Shipping lines, NVOCCs, CFS, dangerous goods warehouses, and trucking companies. | Even if regulations allow, carriers or facilities may refuse acceptance. |
| Main Confirmation Items | Check whether carriage on passenger aircraft is allowed, conditions for cargo aircraft only, charge state, short circuit prevention, packaging, and quantity limits. | Check shipping line acceptance, CFS in-gate conditions, eligibility for LCL consolidation, warehouse storage, and container stuffing. | Operational conditions differ between sea and air transport even for the same UN number. |
| Common Points of Delay | Delays often occur during airline confirmation, courier acceptance checks, and airport warehouse in-gate. | Delays frequently happen at shipping line dangerous goods approval, CFS in-gate, acceptance of consolidation, and warehouse receipt. | Verify battery information and UN 38.3 documentation from the quotation stage. |
| Handling of Abnormal Goods | Damaged, defective, and recalled products are subject to particularly stringent checks. | With sea transport, abnormal goods may not be treated the same as regular products. | Abnormal condition cargo should be treated separately from standard new batteries during confirmation. |
| Lead Time | Prior approval and document checks require more time than usual cargo. | Dangerous goods booking, CFS in-gate coordination, and warehouse confirmation also take additional time. | Avoid proceeding with the same deadline as regular cargo. |
Precautions for Air Transportation
For air transportation, cargo consisting solely of lithium batteries, especially standalone lithium-ion batteries, may be restricted to cargo aircraft only or subject to specific limitations on passenger aircraft.
Additionally, detailed checks are required for charge state, packaging, short-circuit prevention, drop and crush protection, labeling, markings, and the necessity of a dangerous goods declaration.
| Check Item | What to Confirm | Points to Note | Actions if Issues Arise |
|---|---|---|---|
| Passenger Aircraft Carriage Eligibility | Verify whether the cargo can be carried on passenger aircraft or is limited to cargo aircraft only. | Booking on regular passenger flights may not be possible. | Consider switching to cargo flights, another airline, or sea transport. |
| Carrier-Specific Restrictions | Confirm whether the airline or consolidator imposes any additional restrictions on lithium batteries. | Even if regulations permit, the carrier may refuse acceptance. | Make prior inquiries with airlines or consolidators. |
| Charge State | Check if there are specific requirements for the battery’s charge state during air transport. | Additional confirmation is often necessary for standalone batteries. | Refer to manufacturer documentation and airline conditions. |
| Short-Circuit Prevention | Confirm that terminal protection, individual packaging, or securing inside equipment is in place. | Inadequate short-circuit prevention can lead to acceptance refusal. | Consider repackaging, terminal protection, or individual packaging. |
| Packaging | Ensure packaging prevents drops, crushing, and damage. | Standard packaging for general goods may be insufficient. | Use dangerous goods packaging, reinforced packaging, or repackage as needed. |
| Marking and Labeling | Confirm presence of required marks, labels, and external container markings. | Inadequate markings may cause delays or rejection at airport warehouses or by airlines. | Correct markings before in-gate. |
| Dangerous Goods Declaration | Check whether a dangerous goods declaration is required. | Requirements vary depending on conditions; confirm with the airline. | Prepare necessary documents before booking and in-gate. |
Some airlines may refuse shipments of standalone lithium batteries or certain lithium battery configurations even if IATA Dangerous Goods Regulations allow them. Therefore, before booking air transport, it is critical to present cargo details, UN numbers, packaging conditions, quantities, and documents to the airline or consolidator to confirm acceptance eligibility.
Points to Note in Maritime Transport
In maritime transport, lithium batteries may be classified as dangerous goods under the IMDG Code.
When booking with the shipping line, confirm the UN number, proper shipping name, class, packaging type, quantity, emergency response information, and submit dangerous goods details or related documents as required.
| Check Item | What to Confirm | Points of Caution | Actions if Issues Arise |
|---|---|---|---|
| Shipping Line Acceptance | Confirm whether the shipping line will accept the lithium battery cargo. | Conditions may vary depending on the shipping line, route, and transshipment ports. | Consider alternative shipping lines, routes, or direct shipment paths. |
| CFS Receipt Conditions | Confirm whether the CFS can accept the cargo. | The CFS may refuse cargo even if the shipping line accepts it. | Consider alternative CFS locations, dangerous goods warehouses, or converting to FCL. |
| LCL Consolidation Permissibility | Confirm whether the cargo can be consolidated with other goods. | Mixing may be prohibited due to dangerous goods combinations or CFS conditions. | Review consolidation eligibility, segregation conditions, converting to FCL, or separate shipments. |
| Warehouse Storage | Confirm dangerous goods warehouse availability, general warehouse access, temperature, and storage conditions. | General warehouses may refuse acceptance. | Consider using a dangerous goods facility, direct delivery to port, or adjusting receipt dates. |
| Outer Packaging Markings | Confirm required marks, labels, and dangerous goods markings. | Incomplete or missing markings could lead to rejection of receipt or shipment delays. | Make corrections to markings before in-gate. |
| Container Loading | Confirm stowage, securing methods, damage prevention, and compatibility with other cargo. | Prevent damage to batteries and short circuits. | Verify loading requirements, securing procedures, and consolidation conditions. |
For LCL consolidation at a CFS, confirm in advance the cut-off dates for dangerous goods receipt, allowable receipt days, label compliance, compatibility with other cargo, and warehouse acceptance conditions. Cargo containing lithium batteries handled at the last minute with the same approach as general cargo may be refused acceptance or experience shipment delays.
Relation to Non-Dangerous Goods Certificates
Even when a non-dangerous goods certificate is submitted by the shipper, judgment should not be made solely based on that document for cargo containing lithium batteries.
When lithium batteries are included, it is necessary to verify, in addition to the non-dangerous goods certificate, the product specifications, battery information, UN38.3 test documentation, packaging condition, and applicable conditions depending on the mode of transport.
| Item to Verify | Details to Confirm | Action When Inconsistencies Are Found | Responsible Party |
|---|---|---|---|
| Non-Dangerous Goods Certificate | Confirm the basis for non-dangerous classification, applicable products, date of issuance, and issuer. | Verify that it matches the cargo concerned. | Shipper, Manufacturer |
| Product Specifications | Confirm presence or absence of batteries, battery type, model number, capacity, and quantity. | Check for inconsistencies with battery information on the non-dangerous goods certificate. | Shipper, Manufacturer |
| UN38.3 Documentation | Verify documentation regarding the test requirements for the batteries involved. | If documentation is missing, hold off on acceptance decision and seek confirmation. | Shipper, Manufacturer, Dangerous Goods Specialist |
| Actual Cargo Information | Confirm presence of spare batteries, replacement batteries, battery packs, and goods returned for repair. | Ensure no batteries not listed in documentation are included. | Shipper, Warehouse, Delivery Company |
| Mode of Transport | Confirm whether the shipment is by air, sea, or courier transport. | Verify that the basis for non-dangerous classification is applicable for the relevant transport mode. | Airlines, Shipping Lines, CFS, Courier Companies |
Special care is needed to confirm whether mobile batteries, batteries for power tools, storage batteries, spare batteries, replacement batteries, samples, repair returns, and recall items can be handled as regular cargo.
Common Product Name Omissions on Invoices
Lithium battery cargo may be listed under product names on invoices that do not clearly indicate the presence of dangerous goods.
| Example Invoice Entry | Why It Is Easily Overlooked | Recommended Approach | Documents to Verify |
|---|---|---|---|
| parts | Listed simply as parts, making it unclear if battery packs or spare batteries are included. | Check parts details, photos, and product specifications to confirm the presence of batteries. | Parts list, photos, product specifications |
| accessory | Described as accessories, which may include replacement batteries. | Verify set contents, presence of spare batteries, and battery model numbers. | Set content list, packing details, battery specifications |
| electronic goods | General term for electronic devices, obscuring whether batteries are built into the equipment. | Confirm product lists, model numbers, and presence of internal batteries. | Product list, model information, product specifications |
| toy | May contain batteries embedded within the toy. | Confirm if batteries are built-in, included in the package, or if spares are present. | Product descriptions, photos of the actual item, battery information |
| gift | Gift items can include mobile batteries or devices with batteries. | Verify detailed set contents. | Set content list, item photos, SDS |
| promotional item | Promotional products might include LED devices, rechargeable equipment, or mobile batteries. | Check product specifications and battery details. | Product specifications, battery documentation, photos of actual items |
| sample | Treated as samples, dangerous goods verification is often skipped. | Even for small quantities, confirm battery presence and transport conditions. | Product list, battery details, SDS |
| repair goods | Returned repair items may contain degraded or damaged batteries. | Check for damage, swelling, heat generation, or recall status. | Repair details, photos of the actual item, manufacturer confirmation |
Freight forwarders should verify the product name, usage, presence of batteries, spare batteries, and battery packs, and request additional documentation from the shipper as necessary.
Comparison Table of Freight Forwarder Involvement
| Category | What Can Be Supported | What Should Not Be Determined | Practical Response |
|---|---|---|---|
| When Receiving Product Names at the Quotation Stage | Confirm whether lithium batteries, spare batteries, or battery packs are included. | Assuming regular cargo based solely on product names such as parts, accessory, or sample. | Request detailed product descriptions, photos, product specifications, and battery information. |
| When the Shipper States “Not Dangerous Goods” | Verify supporting documents such as SDS, product specifications, UN38.3 test reports, and non-dangerous goods certificates. | Concluding it is regular cargo based only on the shipper’s explanation. | Cross-check documents with the actual cargo to make a judgment. |
| When Confirming Battery Type | Identify if the battery is lithium-ion or lithium metal. | Determining the UN number based only on the explanation “lithium battery.” | Check battery specifications, manufacturer data, and UN38.3 test reports. |

| When Reviewing UN38.3 Test Documentation | Verify that the battery, model number, manufacturer, revision date, and test target match. | Assuming mere presence of the document is sufficient. | Cross-check the documentation details against the actual cargo. |
| When Arranging Air Transport | Confirm IATA Dangerous Goods Regulations and the conditions of airlines and courier companies. | Assuming approval for maritime transport automatically allows air transport. | Check passenger aircraft allowance, cargo-only aircraft restrictions, quantity, packaging, and charge status. |
| When Arranging Sea LCL Consolidation | Confirm conditions with shipping lines, CFS, consolidators, and dangerous goods warehouses. | Assuming that if the shipping line accepts it, the CFS also accepts it. | Verify CFS in-gate conditions, consolidatability, and warehouse acceptance requirements. |
| When Handling Damaged or Returned Repair Items | Check for damage, swelling, heat generation, leakage, and recall status. | Assuming that returned goods can be treated the same as new goods simply because new goods shipped successfully before. | Confirm separately with the manufacturer, dangerous goods specialists, and the carrier. |
Common Practical Issues
| Case | Issue | Documents / Parties to Check | Suggested Response |
|---|---|---|---|
| Cargo declared as electronic components included spare batteries | Battery confirmation as standalone or packed with equipment was overlooked. | Product details, photos, battery information, shipper | Reconfirm UN number, battery type, packaging, and short-circuit prevention. |
| Airline refused acceptance of lithium batteries as standalone cargo | Airline-specific conditions or loading restrictions may not have been checked. | Airline response, SDS, battery specifications, quantity details | Consider alternative airlines, dedicated freighter aircraft, or sea transport. |
| UN38.3 documentation model number did not match actual cargo | There may be use of documentation for a different battery. | UN38.3 test summary, battery model number, manufacturer confirmation | Obtain a test summary corresponding to the actual battery. |
| Returned repair goods included swollen batteries | May not be handled as regular lithium battery cargo. | Photos of actual cargo, repair details, manufacturer’s opinion, dangerous goods specialist | Pre-check with airline, shipping company, and dangerous goods specialist. |
| CFS stopped bonded receipt confirmation for lithium battery cargo | Insufficient CFS acceptance conditions or hazardous cargo information. | SDS, UN number, battery information, UN38.3 documentation, CFS response | Submit required documents and confirm acceptance possibility. |
| Confused between batteries packed with equipment and batteries installed inside equipment | UN number, packaging, and labeling requirements could differ. | Packing contents, battery installation status, presence of spare batteries | Verify packing list and photos, then correct classification as needed. |

| Non-dangerous goods certificate was present but battery information was insufficient | Basis for non-dangerous status cannot be matched with actual battery information. | Non-dangerous goods certificate, product specifications, battery documentation, UN38.3 documentation | Hold shipping as regular cargo and reconfirm with shipper and manufacturer. |
4-Column Verification Checklist
| Verification Scenario | Party to Confirm With | Items to Confirm | Actions if Issues Are Found |
|---|---|---|---|
| When the inquiry states electronic devices, parts, or samples | Shipper / Manufacturer | Confirm presence of lithium batteries, spare batteries, replacement batteries, or battery packs. | If unclear, request product specifications, actual photos, or product datasheets. |
| When confirming battery type | Shipper / Manufacturer | Confirm whether the battery is lithium-ion or lithium metal. | If unknown, request battery specifications or manufacturer’s confirmation documents. |
| When confirming battery form | Shipper / Warehouse / Manufacturer | Confirm whether it is a standalone battery, included with equipment, or built into equipment. | Check packing details, actual photos, and battery installation status. |
| When confirming the UN number | Shipper / Manufacturer / Dangerous Goods Specialist | Confirm whether it corresponds to UN3480, UN3481, UN3090, or UN3091. | If uncertain, do not proceed as general cargo; request classification documents. |
| When verifying UN38.3 documentation | Shipper / Manufacturer | Confirm test summary, battery model, manufacturer, revision date, and match with the cargo. | If model numbers do not match or documents are incomplete, request resubmission of documentation appropriate for the battery. |
| When arranging air transport | Airline / Courier / Air Agent | Confirm handling under IATA Dangerous Goods Regulations, passenger aircraft carriage eligibility, cargo-only aircraft, packaging, quantity, and charge state. | If refused, consider a different airline, cargo aircraft services, or sea transport. |
| When arranging maritime LCL consolidation | Shipping Line / NVOCC / CFS / Consolidator | Confirm treatment under the IMDG Code, CFS acceptance, consolidation eligibility, outer packaging markings, and warehouse conditions. | If refused, consider FCL shipment, different CFS, dangerous goods warehouse, or next vessel. |
| When handling damaged, repair-returned, or recalled products | Shipper / Manufacturer / Dangerous Goods Specialist / Carrier | Confirm damage, swelling, heat generation, leakage, defects, reason for collection, and recall reason. | Do not handle as regular cargo; obtain prior confirmation from carrier and specialists. |
Example 1: Cargo Declared as Electronic Components Containing Spare Batteries
The invoice simply listed "parts," and a request for an air transport quotation was received treating the shipment as regular cargo.
However, on reviewing the product details, spare batteries were included separately from the main device. In this case, the shipment is not just electronic components but must be treated as lithium battery cargo, requiring confirmation of the UN number, battery type, battery form, quantity, packaging, and short-circuit prevention measures.
The freight forwarder checks the product specifications, battery datasheets, packing details, actual photos, and UN38.3 test documentation.
For air transport, the freight forwarder contacts the airline or courier company to confirm whether the batteries are shipped alone or installed in equipment and checks acceptance eligibility accordingly.
Example 2: Case Where the UN38.3 Document Battery Model Number Does Not Match the Actual Cargo
This occurs when the shipper submits a UN38.3 test summary, but the battery model number listed in the document does not match the battery model installed in the actual cargo.
In such cases, there is a possibility that documentation for a different battery has been submitted, making it difficult for airlines or shipping lines to decide on acceptance.
The freight forwarder cross-checks the product specifications, battery model number, manufacturer name, the battery covered by the UN38.3 document, and the revision date.
If the model numbers do not match, the shipper should be asked to resubmit the correct UN38.3 test summary or a manufacturer’s confirmation letter corresponding to the actual battery, and acceptance eligibility must be reverified.
Example 3: Attempt to Switch Lithium Battery Cargo Received by Sea to Air Transport
This case involves a shipper’s request to switch lithium battery cargo initially received via sea transport to air transport in order to shorten the delivery time.
Lithium battery cargo accepted by sea may not automatically be accepted for air transport. Key issues in air transport include whether the cargo can be carried on passenger aircraft, requirement for cargo-only aircraft, charge state, packaging standards, quantity limitations, and airline-specific conditions.
The freight forwarder confirms the UN number, battery type, battery form, quantity, rated watt-hour capacity or lithium content, UN38.3 documentation, and packaging condition, then consults with the airline regarding acceptance.
If air acceptance is denied, options such as maintaining sea transport, using cargo-only flights, selecting a different airline, splitting the shipment quantity, or postponing shipment are presented to the shipper.
Example 4: Case of Swollen Batteries Included in Returned Repair Items
This involves electronic devices returned for repair that contained swollen lithium batteries.
In such cases, the cargo may not be handled as regular lithium batteries embedded in equipment. It is necessary to verify swelling, heat generation, leakage, damage, and recall status, and to assess these separately from standard items.
The freight forwarder confirms the battery condition, reason for repair, recall status, and manufacturer’s opinion with the shipper, manufacturer, and repair service.
Based on this, the freight forwarder consults in advance with airlines, shipping lines, and dangerous goods specialists, and explains to the shipper the possibility of refusal of acceptance, special packaging requirements, separate arrangements, or shipment suspension.
Points to Confirm with the Shipper
For cargo containing lithium batteries, it is important to obtain specific information from the shipper at an early stage.
- Whether the battery is a lithium-ion battery or a lithium metal battery.
- Whether the battery is standalone, packed with equipment, or installed in equipment.
- Which UN number applies: UN3480, UN3481, UN3090, or UN3091.
- Whether the watt-hour rating or lithium content has been confirmed.
- Whether the number of batteries, battery weight, and total quantity have been confirmed.
- Whether a UN38.3 test summary is available.
- Whether the model number, manufacturer, and battery referenced in the UN38.3 documentation correspond to the actual cargo.
- Whether the batteries are damaged, defective, recalled, returned for repair, or subject to any recovery.
- Whether acceptance for air and sea transport is possible.
- Whether the cargo meets the acceptance criteria of the airline, shipping carrier, CFS, warehouse, and courier company.
- If a non-dangerous goods certificate is provided, whether it is consistent with the battery information.
Common Misconceptions
In lithium battery transport, the cargo often appears to be electronic devices or components, which can lead to skipping hazardous goods verification.
| Misconception | Practical Consideration | What Should Be Confirmed |
|---|---|---|
| Not a dangerous good because it is just built into the device | Even when embedded in a device, lithium battery cargo may require confirmation as hazardous goods. | Confirm the UN number, battery type, quantity, and protection status within the device. |
| Spare batteries can be treated the same as those in the main device | Spare batteries may be handled differently whether shipped alone or packed with devices. | Confirm spare battery quantity, packaging, short-circuit prevention, and UN number. |
| Small size means it is not hazardous | Even small batteries require confirmation depending on battery type, quantity, and transport mode. | Check watt-hour rating, lithium content, number of units, and packaging conditions. |
| Since it was shipped before, the same applies this time | Transport mode, airline, shipping line, quantity, packaging, and regulation updates may affect conditions. | Reconfirm based on the current shipment’s conditions. |
| Repair returns can be treated the same as regular product returns | For repair returns, checking for damage, deterioration, swelling, or overheating is crucial. | Confirm presence of damage, defects, or recall status. |
| A non-dangerous goods certificate is sufficient | It is necessary to verify consistency with battery details and UN38.3 documentation. | Cross-check product specifications, battery details, and UN38.3 reports. |
| Having UN38.3 documentation is enough | Confirm that the battery model, manufacturer, and revision date match the actual cargo. | Compare UN38.3 test summaries, battery model, and product specifications. |
| If accepted for sea transport, the battery cargo can also be accepted for air transport | In air transport, issues include passenger plane carriage eligibility, cargo aircraft only, charge status, and airline-specific requirements. | Confirm IATA Dangerous Goods Regulations, airline conditions, quantity, and packaging. |
Key Points Freight Forwarders Should Note
Transporting lithium batteries is a very common hazardous goods check item in modern international logistics.
- Do not rely solely on the product name for classification.
- Verify the presence of batteries, including spare batteries, replacement batteries, and battery packs.
- Distinguish between lithium-ion batteries and lithium metal batteries.
- Confirm whether batteries are shipped as standalone items, included with equipment, or installed within equipment.
- Cross-check the UN number, battery details, UN38.3 documentation, and packaging condition.
- Verify air transport and sea transport conditions separately.
- Check requirements specific to airlines, shipping lines, CFS, warehouses, and courier companies.
- Damaged, defective, recalled, or returned batteries should not be treated as regular cargo.
- If there is any uncertainty, confirm in advance with the shipper, manufacturer, hazardous goods specialists, airlines, and shipping lines.
Summary
Lithium battery transport involves the practical handling of cargo containing lithium-ion and lithium metal batteries according to hazardous materials regulations for air and sea transportation.
For lithium battery cargo, it is necessary to verify the battery type, whether the battery is shipped alone, with equipment, or built into equipment, the appropriate use of UN3480, UN3481, UN3090, and UN3091, watt-hour rating, lithium content, quantity, compliance with UN38.3, and the packaging condition.
In particular, for air transport, careful confirmation is required of airline-specific acceptance conditions, passenger aircraft carriage eligibility, dedicated cargo aircraft requirements, short-circuit prevention, packaging, marking, and the need for a dangerous goods declaration. For sea transport, confirmation covers carrier acceptance, CFS in-gate conditions, eligibility for LCL consolidation, and warehouse storage criteria.
Lithium battery transport is not just a matter of hazardous goods knowledge; it is a critical practical topic for freight forwarders that directly relates to preventing rejection of loading, shipment delays, warehouse in-gate refusals, and serious accident prevention. The fundamental practice is to obtain documentation from the shipper at an early stage and prepare the cargo in a condition that can be safely transported under the chosen transport mode and carrier conditions.
The key point of this article is to treat lithium battery transport as a practical matter to be verified by combining factors including battery presence, battery type, form, UN number, UN38.3 documentation, cargo condition, packaging, transport mode, and carrier acceptance conditions, rather than deciding solely on whether batteries are included.
