ການນໍາສະເຫນີ

Lithium batteries are the quiet engine behind almost every fast-growing product category that moves from Chinese factories to American buyers. Power banks, e-bikes, drones, portable power stations, smart home devices, wireless earbuds, vacuum cleaners and power tools all depend on them. The same chemistry that makes these products light, powerful and rechargeable also makes the batteries inside them a regulated hazard in transport. A damaged or defective cell can go into thermal runaway, and on an aircraft or inside a stacked container that is a problem no one wants to meet at 35,000 feet or in the middle of the Pacific.

That is why a lithium battery shipment is never handled like an ordinary carton of consumer goods. Carriers, airlines, ports, customs authorities and warehouses on both sides of the Pacific apply ສິນຄ້າອັນຕະລາຍ rules, and they apply them strictly. A missing test summary, a wrong UN number or a battery charged a few points above the permitted level can mean a refused booking, a rolled container, a fine, or cargo sitting in a bonded warehouse accruing storage charges while the sales calendar keeps moving.

This guide walks through the rules and paperwork that matter in practice for shipments from China to the United States, based on the regulations in force as of late October 2026. It covers classification, the 2026 changes to the IATA Dangerous Goods Regulations, the documents you need on the China side and the US side, packing and labeling, how to choose between air and ocean, duty and tariff considerations, and the mistakes that most often get cargo stopped. Where Topway Shipping fits into the chain, we explain that too. Treat the numbers here as a working reference, and always confirm final requirements with your forwarder and carrier before the cargo is booked, because airline and carrier variations can be stricter than the base regulations.

Why Lithium Batteries Are Regulated as Dangerous Goods

What Class 9 Means for Your Cargo

Under the UN Model Regulations, which feed into the IATA Dangerous Goods Regulations for air, the IMDG Code for sea and 49 CFR for transport within the United States, lithium batteries fall into Class 9, miscellaneous dangerous goods. Class 9 sounds mild next to explosives or flammable liquids, but in practice it brings the full machinery of dangerous goods compliance: a UN number, a proper shipping name, tested packaging, hazard labels, trained personnel and, above certain size thresholds, a signed shipper declaration.

The reason is straightforward. When a lithium cell fails, it releases heat and flammable gas, and it can ignite neighboring cells. Cargo fires on aircraft and container ships have been traced to mis-declared or poorly made batteries often enough that regulators keep tightening the rules year after year. For a shipper, the practical lesson is that compliance is not a formality handled at the airport counter. It begins at the factory, with how the cells were tested and packed, and it ends only when the goods are delivered to the US consignee.

The 2026 Changes You Cannot Ignore

The most important recent change for air shipments is the arrival of the 67th Edition of the IATA Dangerous Goods Regulations, which became mandatory on January 1, 2026. The edition turns a long-running safety recommendation into a hard requirement for some shipments: lithium-ion cells and batteries packed with equipment under Packing Instruction 966 must now be offered at a state of charge not exceeding 30 percent of rated capacity. Lithium-ion batteries shipped on their own under UN 3480 have been subject to the 30 percent limit for several years, and battery-powered vehicles are also tied to a 30 percent limit or an indicated capacity of no more than 25 percent.

There is nuance, and it is where many shippers get caught. For lithium-ion batteries contained in equipment under Packing Instruction 967, the 30 percent figure remains a recommendation rather than a universal mandate in the 2026 edition, and several airlines publish their own variations that go further than IATA. Sodium-ion batteries, which now have their own entries, are treated in parallel. In other words, the safe operating assumption for any lithium-ion product going by air in 2026 is that it will be asked to prove a low state of charge, and factories should be instructed to discharge to 30 percent or below before packing.

Trade policy has also moved sharply this year, and it affects landed cost as much as compliance affects schedule. A 25 percent Section 301 tariff on non-EV lithium-ion batteries from China took effect on January 1, 2026. In February 2026 the US Supreme Court ruled that the International Emergency Economic Powers Act does not authorize tariffs, which removed the IEEPA-based duties, while Section 301 and Section 232 tariffs were left in place. Temporary replacement measures have since come and gone, so the tariff stack on a given battery product should be verified on the day of entry rather than assumed from last quarter’s quote.

Know Your Battery: Classification and UN Numbers

Every compliant shipment starts with correct classification, and correct classification starts with knowing exactly what is in the box. The same product can fall into different UN numbers depending on whether the battery is shipped alone, packed in the same carton as a device, or installed inside the device. Each of those three situations has its own packing instruction, its own limits and its own paperwork consequences.

Table 1. Common lithium battery classifications for air transport

ປະເພດການຂົນສົ່ງ	ເລກສປຊ	ຜະລິດຕະພັນ ທຳ ມະດາ	ຄຳແນະນຳກ່ຽວກັບການຫຸ້ມຫໍ່ດ້ວຍອາກາດ
ແບັດເຕີຣີ Lithium-ion ຈັດສົ່ງໂດຍລຳພັງ	ສປຊ 3480	Power banks, replacement packs, standalone e-bike or tool batteries	IP 965
ຫມໍ້ໄຟ Lithium-ion ບັນຈຸອຸປະກອນ	ສປຊ 3481	Drone with spare battery in the same carton, tool kit with separate pack	IP 966
ຫມໍ້ໄຟ Lithium-ion ທີ່ມີຢູ່ໃນອຸປະກອນ	ສປຊ 3481	Laptops, phones, earbuds, smart watches, tools with battery installed	IP 967
Lithium metal batteries shipped alone	ສປຊ 3090	Primary cells such as CR-type and high-capacity lithium primary packs	IP 968
Lithium metal batteries packed with or in equipment	ສປຊ 3091	Trackers, sensors, devices using lithium primary cells	ປີ 969 / ປີ 970
ລົດທີ່ໃຊ້ແບັດເຕີຣີ Lithium-ion	ສປຊ 3556	E-scooters and similar vehicles where classification as a vehicle applies	Vehicle entry, check current DGR

 

One detail catches sellers out repeatedly: power banks are batteries, not electronic gadgets, and they ship as UN 3480 under Packing Instruction 965. That means they are subject to the standalone battery rules, including the cargo-aircraft-only restriction on many lithium-ion battery shipments, rather than the more forgiving rules that apply to batteries installed in equipment. If your listing is for a power bank, a portable power station or a battery pack that fits into a tool, assume the stricter classification until your forwarder confirms otherwise.

Watt-Hour and Lithium Content Thresholds

Size determines how heavily a shipment is regulated. For lithium-ion products the measure is watt-hours, which you can calculate by multiplying the nominal voltage by the capacity in amp-hours. For lithium metal products the measure is the equivalent lithium content in grams. The thresholds below decide whether a shipment falls into the lightly regulated tiers or the fully regulated tier that requires a shipper declaration and cargo-aircraft-only handling.

Table 2. Simplified watt-hour and lithium content thresholds

ເຄມີສາດແບັດເຕີຣີ	Cell limit	Battery limit	Above the limit
Lithium-ion	20 Wh	100 Wh	Fully regulated tier (Section IA), shipper declaration, cargo aircraft only for standalone batteries
ໂລຫະ Lithium	1 g lithium content	2 g lithium content	Fully regulated tier, shipper declaration, cargo aircraft only
Very small lithium-ion units	2.7 Wh	2.7 Wh	Below this, the least restrictive tier applies; above it, labeling and testing requirements increase

 

These thresholds are simplified, and the regulations contain additional conditions on quantity per package, number of cells per device and package weight. As a rough guide, standalone lithium-ion batteries in the middle tier are limited to 10 kg net per package, while the fully regulated tier on cargo aircraft allows up to 35 kg per package. Batteries packed with equipment are limited to 5 kg net per package. Because the exact conditions shift between editions, factories should always provide the watt-hour rating on the battery label and in the test summary, and your forwarder should check the numbers against the current edition.

What Must Be Ready on the China Side

UN 38.3 Testing and the Test Summary

The UN Manual of Tests and Criteria, section 38.3, is the foundation of battery transport safety. Every lithium cell and battery type must pass a series of tests covering altitude simulation, thermal cycling, vibration, shock, external short circuit, impact or crush, overcharge and forced discharge. Passing is not enough on its own; since 2020 the manufacturer or distributor must make a test summary available to anyone who requests it, and airlines and forwarders now ask for it routinely.

A usable test summary names the manufacturer, the battery model, the test laboratory, the date and the test report number, and it confirms that the tested design matches the battery being shipped. If a factory has changed cells, capacity or circuitry since the test was done, the old summary no longer covers the product. Forwarders see this problem most often with private-label sellers who reuse a certificate that belongs to a different capacity of the same series.

Transport Condition Appraisal and Dangerous Goods Packaging Certificates

China has its own layer of requirements on top of the international rules. For sea shipments, Chinese ports and carriers typically require a goods transport condition appraisal report for lithium batteries, issued by a recognized inspection or testing body, along with the dangerous goods packaging performance inspection certificate and the packaging use appraisal for the cartons or drums that will hold the cargo. For air shipments, airports and airlines in China commonly require an air transport condition appraisal report, again from a qualified third party.

These certificates are not interchangeable. The report issued for air does not automatically satisfy a sea booking, and a packaging certificate covers a specific packaging design, not the factory’s whole product line. Validity periods and acceptance practices also vary by port and by carrier, which is why experienced forwarders ask for the full document set before quoting rather than after the cargo has arrived at the warehouse.

Lead times matter here. A new battery product that has never shipped by sea may need several weeks to obtain the appraisal, and rushing it is rarely possible. Sellers planning a launch should start the certification and packaging work in parallel with production, not after the first units come off the line.

Safety Data Sheet and Product Data

A 16-section Safety Data Sheet for the battery is expected by carriers and warehouses even though it is not a document the US Department of Transportation itself requires for every shipment. The SDS must match the battery being shipped, state the correct UN number and proper shipping name, and list emergency contact information. Along with the SDS, keep product photos, the battery specification sheet, and a clear picture of the label showing watt-hours and voltage, because forwarders use them to verify classification before accepting the booking.

Choosing a Forwarder and a Loading Point

Not every warehouse in Shenzhen, Dongguan or Ningbo is licensed to handle dangerous goods, and not every forwarder will accept lithium cargo on every lane. The factory should deliver the goods to a facility that can inspect packaging, check state of charge, apply labels and prepare the declaration under the supervision of trained staff. Picking up cargo from the factory door with a standard truck and no dangerous goods driver credentials is one of the faster ways to have a shipment rejected before it leaves the province.

This is where an experienced China-US forwarder earns its fee. Topway Shipping, headquartered in Shenzhen and operating since 2010, manages first-leg transportation from the factory to the export point as part of a full-chain service, so the same team that checks the paperwork also controls how the cargo is handled between the factory gate and the airport or port.

The Document Package

A lithium battery shipment travels with more paperwork than a standard cargo movement, and each document answers a different question for a different party. The table below summarizes what most China to US lithium shipments need, with the caveat that the exact set depends on battery size, mode of transport and the carrier.

Table 3. Typical document package for China to US lithium battery shipments

The Shipper’s Declaration for Dangerous Goods deserves particular attention because it is a legal statement. The person who signs it certifies that the consignment is correctly described, classified, packed, marked and labeled, and that it complies with the applicable regulations. That person must be trained and certified for the relevant mode. Many sellers hand this responsibility to the forwarder, which is acceptable as long as the forwarder has qualified staff and the seller supplies accurate information, because the declaration is only as reliable as the data behind it.

For air shipments, the air waybill carries its own notations. Lower-tier lithium battery shipments that do not require a full declaration still need the correct statement on the air waybill identifying the packing instruction and, where applicable, the cargo-aircraft-only status. A missing or incorrect notation is a common reason for cargo to be held at the origin airport.

Additional Documents for Ocean Shipments

Ocean shipments of lithium batteries add a layer of paperwork linked to the container itself. A dangerous goods declaration must be submitted to the carrier ahead of the cut-off, and for full container loads a container packing certificate confirms that the load was secured, that incompatible cargo was not loaded together, and that the container was inspected before sealing. The cut-off for dangerous goods documents is usually earlier than the cut-off for general cargo, sometimes by several days, so the usual last-minute booking habits do not work.

On the US side, importers filing ocean shipments must submit the Importer Security Filing at least 24 hours before the cargo is loaded onto the vessel at the foreign port. Late or inaccurate filings carry penalties, and because dangerous goods cargo already attracts extra scrutiny, an ISF error is a risk worth eliminating.

Packing, Marking and Labeling Rules

Packaging That Passes

Packaging for lithium batteries has to do two jobs: prevent the battery from short-circuiting or being damaged, and contain the consequences if something still goes wrong. Batteries must be protected against short circuit by insulating terminals, using individual inner packaging or separators, and ensuring that cells cannot shift inside the carton. For larger packages, the outer packaging should meet UN specification standards, and in the fully regulated tiers the package must be marked with the UN specification mark and tested accordingly.

Equipment packed with batteries has to be secured so the device cannot be switched on accidentally during transit. This sounds minor, yet an activated drone or heated power tool in a cargo hold is a classic source of incidents. Use switch locks, tape or protective caps, and keep battery packs in inner packaging that prevents contact with metal objects.

Damaged, defective or recalled batteries are a separate category with much stricter conditions, and in most commercial scenarios they should not be shipped through standard channels at all. If you receive a customer return or a suspect pack from a production line, contact your forwarder before attempting to move it.

Marks and Labels

Labeling is the visible signal that the cargo has been classified and is ready for dangerous goods handling. Depending on the tier, packages must display the UN number, the lithium battery hazard label (Class 9A), and for cargo-aircraft-only shipments the Cargo Aircraft Only label. Orientation arrows and the shipper and consignee details are required in some cases, and the overpack marking applies when multiple packages are placed together in an outer container.

Labels must be durable, correctly sized and placed on a contrasting background so they remain readable after rough handling. A faded or half-covered label is as good as no label from the airline’s perspective. Labels should be applied or verified at the dangerous goods warehouse, not left to the factory, because forwarders are held responsible for what actually reaches the carrier.

State of Charge Before Packing

Given the 2026 IATA changes, the factory should discharge batteries to a state of charge not exceeding 30 percent before packing, or to the indicated capacity limit that applies for battery-powered vehicles. A calibrated tester or the battery’s built-in indicator is used to verify the level. Some airlines now ask for a state of charge statement on the commercial documents or a signed declaration from the factory. Charging the batteries just before shipment to impress the end customer is a habit that has to stop in ການ​ຂົນ​ສົ່ງ​ທາງ​ອາ​ກາດ, since over-limit batteries are likely to be rejected at acceptance.

Choosing the Right Mode: Air, Ocean FCL, Ocean LCL or Express

The right mode depends on battery size, product value, urgency and the number of units. Lithium battery shipments have a narrower choice than general cargo because carriers can refuse dangerous goods on specific services, and because the fully regulated tiers restrict some batteries to cargo aircraft only. The table compares the main options at a practical level.

Table 4. Mode comparison for lithium battery shipments, China to US

ຮູບແບບການ	ການຂົນສົ່ງທົ່ວໄປ	ທີ່ດີທີ່ສຸດສໍາລັບ	ຂໍ້ຈຳກັດຫຼັກ
Air freight (general air cargo)	Roughly 5 to 10 days door to door, depending on acceptance and routing	High-value, urgent, smaller volumes	30% SoC rules, cargo-aircraft-only for many standalone batteries, airline acceptance limits
ມະຫາສະໝຸດ FCL	Roughly 14 to 20 days port to port to the US West Coast, 30 to 40 days to the East Coast, plus inland and booking time	Large, regular volumes, heavy batteries, e-bikes and power stations	Carrier acceptance of Class 9, dangerous goods surcharge, earlier document cut-off
Ocean LCL	ຄ້າຍຄືກັນກັບ FCL ບວກກັບເວລາລວມ	ການຂົນສົ່ງທາງທະເລຂະໜາດນ້ອຍກວ່າ	Fewer carriers and consolidators accept dangerous goods LCL, so options are limited
ສົ່ງດ່ວນ	ຫຼາຍ​ມື້	Samples and very small quantities	Many courier services reject standalone lithium batteries or cap quantities heavily

 

Air Freight in Practice

Air is the default for urgent or higher-value goods, and for small-volume consignments such as power banks and electronics. The airlines that accept lithium batteries publish their own acceptance policies, and these can be tighter than IATA. Some carriers do not accept certain UN 3480 shipments from specific origins, and capacity for dangerous goods is lower than general cargo capacity, especially in peak season.

Book early, have documents pre-approved by the airline’s dangerous goods desk when possible, and keep a buffer in the schedule. If a shipment is rejected at the cargo terminal for a labeling or documentation error, the rebooking can cost days or even a week.

Cost is the other consideration. Air freight for dangerous goods carries a handling surcharge and, because lithium cargo takes up more of an aircraft’s limited dangerous goods allowance, rates are typically higher per kilogram than for general electronics.

Ocean Freight in Practice

Ocean is the economical choice for heavier or bulkier battery products, and for regular replenishment of inventory. Shipping full containers keeps the dangerous goods under one shipper’s control, simplifies documentation and avoids the uncertainty of consolidated loads. Carriers publish their own acceptance rules for lithium batteries and can restrict stowage position, for example by requiring that batteries be stowed away from heat sources or accommodation areas.

LCL is possible but limited. Consolidators have to accept the dangerous goods, the cargo has to be segregated from incompatible cargo, and the schedule is tied to consolidation windows. For most sellers who ship battery products regularly, FCL or a shared dangerous-goods-capable service is the more predictable path.

Plan for the extra time. Between the earlier document cut-off, the inspection and certification steps in China and the possibility of rolled bookings on tight services, the actual door-to-door time for a dangerous goods ocean shipment is often longer than the headline transit time on the schedule.

Topway Shipping offers both FCL and LCL ocean freight from China to major ports worldwide, and combines this with overseas ສາງ and last-mile delivery in the US, so that sea shipments of battery products can be consolidated, cleared and delivered as one coordinated service.

US Side: Customs Clearance, Duties and Compliance

Classification and Basic Duties

On arrival, lithium batteries are classified under the Harmonized Tariff Schedule, most commonly in heading 8507 for electric accumulators. Lithium-ion accumulators fall under subheading 8507.60, while products with batteries installed are classified by the product itself, such as a power tool, a vacuum cleaner or a drone, rather than by the battery. The base duty rate for lithium-ion accumulators is relatively low, but the additional China-specific duties are what shape the cost.

Classification errors are expensive. A product that is declared as a general electronic device when it is actually a battery pack can trigger a different duty rate and invite a Customs and Border Protection review. The importer of record is responsible for the declared classification and value, so the commercial invoice should show the exact model, capacity and the description that matches the test summary and the SDS.

The Tariff Landscape for Chinese Batteries

For non-EV lithium-ion batteries of Chinese origin, the additional Section 301 duty rose to 25 percent on January 1, 2026, following the four-year review completed in 2024. For lithium-ion batteries used in electric vehicles, the 25 percent rate has applied since September 2024. These are in addition to the base rate, and they were not affected by the Supreme Court’s February 2026 decision on IEEPA tariffs.

What has changed since is the layer on top. The IEEPA tariffs on China were invalidated, a temporary global surcharge was introduced under Section 122 for 150 days, and the administration has launched new Section 301 investigations as the follow-up. The result is that the stack of additional duties on a battery shipment depends on the product, the date of entry and any exclusions that apply, so sellers should obtain a duty estimate from their customs broker immediately before shipment rather than relying on a quote from several months earlier.

Duty-free de minimis treatment was also suspended for imports from all countries, which means that small parcels that once entered without duty have been dutiable, although sellers should confirm the current position with a broker. For sellers who built a model around low-value direct parcels, that change matters as much as the battery-specific rules.

Table 5. Landed cost elements for lithium battery imports

ມາດຕາ 301 ໜ້າທີ່	China origin, product type, date of entry	25% on non-EV lithium-ion batteries from January 1, 2026
Other tariff layers	Current trade measures, Section 232 where applicable	Check on the date of entry; this layer has changed repeatedly in 2026

Dangerous goods surcharges	Carrier, lane, mode	Vary by carrier and season; ask for them to be quoted separately
ການເກັບຮັກສາແລະ demurrage	Delays, documentation errors, missed pickup	Often the largest avoidable cost on a rejected shipment

 

Customs Bond, ISF and Other Agencies

Commercial imports above the informal entry threshold need a customs bond, either a single-transaction bond or a continuous bond, and the entry has to be filed by the importer of record or a licensed customs broker. For ocean cargo the ISF filing must be completed before loading, as noted earlier.

The product itself can also face requirements from other agencies and marketplaces. Radio-frequency devices need FCC authorization, and safety standards such as UL 2054 for batteries, UL 2056 for power banks and UL 2271 or UL 2849 for light electric vehicle systems are often demanded by retailers and online marketplaces even where they are not a customs matter. Amazon and other platforms usually ask for the UN 38.3 summary and SDS before approving battery listings, and fulfillment centers will refuse to receive batteries that were classified differently than listed.

Last-Mile Delivery for Battery Cargo

Moving the cargo from the port or airport to the final destination remains a regulated activity inside the United States. The Department of Transportation’s hazardous materials rules, found in 49 CFR, apply to ground transport, and the carrier, the warehouse and the people who prepare the shipment all need the right training. Many parcel networks restrict or surcharge shipments containing batteries, and some warehouses refuse them altogether.

Using a warehouse that is set up for lithium batteries avoids a surprising number of delays. Topway Shipping provides overseas warehousing and last-mile delivery in the US as part of its end-to-end service, so cargo that clears customs can move directly to a warehouse or delivery carrier that already knows the product, rather than being re-handled by multiple parties.

Common Mistakes That Get Lithium Shipments Rejected

Most rejected shipments are not rejected because of exotic rules. They are rejected because of ordinary errors that could have been caught before the cargo left the factory. The table summarizes the problems forwarders see most often and how to avoid them.

Table 6. Frequent causes of rejection and how to avoid them

ຂໍ້ຜິດພາດ	ເປັນຫຍັງມັນຈຶ່ງສໍາຄັນ	ວິທີປ້ອງກັນມັນ
Missing or outdated UN 38.3 summary	Carriers cannot verify the battery passed tests	Match the summary to the exact model, capacity and cell supplier
Wrong classification (power bank shipped as equipment)	Wrong packing instruction, wrong labels, wrong airline acceptance	Confirm UN number with the forwarder before production
State of charge above the limit	Rejected at acceptance in air freight	Discharge to 30% or below and keep a record
Incorrect or damaged labels	Airline or port refuses to accept	Apply and check labels at the dangerous goods warehouse
Undeclared batteries in a mixed carton	Serious violation, possible fines and cargo loss	Declare every battery, including spare packs and button cells
Late dangerous goods document submission	Missed cut-off and rolled booking	Submit documents before the dangerous goods cut-off, not the general one
Using a non-qualified loading point	Cargo refused before it leaves China	Use a forwarder with licensed dangerous goods handling

 

The most expensive mistake is the undeclared battery. Sellers sometimes label a carton of earbuds or a wearable as general cargo, forgetting that the device contains a lithium cell. Regulators and carriers treat misdeclaration as a safety violation rather than a clerical error, and penalties can fall on the shipper, the forwarder and the importer.

Another frequent problem is the mismatch between documents. If the invoice says one model, the packing list says another and the test summary refers to a third, the cargo will be held until the discrepancy is resolved. A simple internal rule helps: one model name, one battery capacity and one set of figures everywhere.

How Topway Shipping Handles Lithium Battery Shipments

Since 2010, Topway Shipping, headquartered in Shenzhen, China, has been a professional provider of cross-border e-commerce logistics solutions. The founding team has more than 15 years of experience in international logistics and customs clearance, with a strong focus on China to US transportation, and that experience is built into how battery cargo is planned from the first inquiry.

The service covers the entire logistics chain. First-leg transportation moves goods from the factory to the export point, overseas warehousing holds the stock in the United States, customs clearance handles entry filings and duty management, and last-mile delivery completes the journey to the consignee or the fulfillment center. On the ocean side, Topway Shipping offers flexible full container load and less than container load services from China to major ports worldwide.

For a lithium battery shipment, the first step is a document and classification check: the model, watt-hour rating, test summary, SDS and the intended mode are reviewed together, so that problems such as a wrong UN number or an expired certificate are found before the booking is made. The team then advises on the mode that fits the product, coordinates the packaging and label work at the origin, and prepares the declarations and filings for both sides of the Pacific. Acceptance always depends on the carrier and the specific product, so the earlier the details are shared, the more options remain open.

For sellers who want fewer handoffs, the combined service model is the main advantage. When the origin pickup, the export documents, the ocean or air booking, the US customs entry, the warehouse and the final delivery are managed by one team, the points where lithium shipments usually fail, the gaps between different providers, become much smaller.

A Practical Workflow from Factory to Consignee

A well-run lithium battery shipment follows a predictable sequence. It begins before production, when the seller confirms the classification, the watt-hour rating and the required certificates with the forwarder, and confirms that the factory can supply a current UN 38.3 summary and SDS. Any gaps are fixed at this stage because they cost the least to fix.

Next, the packaging and appraisal work is completed, the factory prepares the goods at the required state of charge, and the cargo is delivered to a dangerous goods capable warehouse. There the forwarder checks the packaging, labels and documents, produces the declaration and books the carrier. After departure, the US customs broker files the entry, confirms the duty estimate against the current tariff position, and arranges delivery with a carrier or warehouse approved for battery cargo.

The point of this sequence is not bureaucracy for its own sake. Each step removes a specific risk, and the cost of skipping one is almost always higher than the cost of doing it. Sellers who treat lithium compliance as part of product planning, rather than as a shipping problem to solve at the last minute, consistently see fewer delays and lower landed costs.

ສະຫຼຸບ

Shipping lithium batteries from China to the US is entirely manageable, but it rewards preparation and punishes improvisation. The core requirements are consistent: classify the battery correctly, hold a current UN 38.3 test summary and SDS, complete the Chinese appraisal and packaging certificates, discharge to the permitted state of charge for air, pack and label to the right tier, and file the correct declarations and customs entries on both sides. In 2026, the mandatory 30 percent state of charge requirement for certain air shipments and the 25 percent Section 301 duty on non-EV lithium-ion batteries have added two more checks to that list.

The most reliable way to avoid rejected bookings and surprise costs is to work with a forwarder that handles the whole chain and checks the details early. Topway Shipping brings together first-leg transportation, FCL and LCL ocean freight, overseas warehousing, customs clearance and last-mile delivery, backed by a team with more than 15 years of China to US experience. If you are planning a battery shipment, send your product details, test documents and target delivery date to Topway Shipping so the route and paperwork can be confirmed before your cargo moves.

ຄໍາ​ຖາມ

Q: Do I need a UN 38.3 test summary for every lithium battery shipment?

A: Yes. Any lithium cell or battery type shipped internationally needs to have passed UN 38.3 testing, and the manufacturer or distributor must be able to provide the test summary on request. Forwarders and airlines usually ask for it before accepting the booking.
