This route runs through Xiamen, the port for more than 90% of Fujian's lithium battery exports, then follows a Panama Canal corridor whose draft limit depends on Gatun Lake; at the far end is the port of Searsport.
US entry is decided as much by paperwork filed in China as by anything at the port. This page sets out 5 points specific to this route, how Anxin handles each one and which documents to prepare.
What we need to start
- Taiwan Strait monsoon Oct–Apr
- Xiamen export
- ISF filer
- Supply-chain tracing file
- HTS code 8507.60
Route profile
What sets Xiamen → Searsport apart
United States
Section 301 duty on Chinese lithium-ion batteries at 25% since January 2026, UFLPA scrutiny of lithium supply chains, ISF 24 hours before loading, and a US-only marking rule for SP188 packages.
Where this route gets difficult
Where Xiamen → Searsport shipments get held up: 5 points
They run from the Xiamen terminal through the voyage to Searsport and the United States import file.
- Origin port
Energy-storage units may go on multipurpose ships
Xiamen's energy-storage transport guide 2.0 (August 2026) notes that some ESS containers are carried on multipurpose ships and requires a pre-voyage meeting with the terminal and lashing parties. It also lists the terminals with class 9 qualification: Xiamen Hyundai terminal, Yuanhai Tongda, and Haixiang berths 7–8.
What Anxin does: For ESS units we confirm early whether the carrier offers container-ship or multipurpose carriage, which qualified terminal is used, and who attends the pre-voyage meeting.
- Sea corridor
North Atlantic winter storms off the US East Coast
The last leg north to Searsport runs up the US East Coast in the North Atlantic, where NOAA's Ocean Prediction Center has recorded hurricane-force mid-latitude storms in every month from October to April, most often in January.
What Anxin does: For October–April arrivals we check blocking and bracing on stuffing photos before sealing, and allow slack in the delivery plan.
- Import country
ISF closes 24 hours before loading in Xiamen
The Importer Security Filing must reach CBP no later than 24 hours before the container is laden aboard the vessel abroad. CBP's liquidated damages guidelines provide for a claim per violation for late, inaccurate or incomplete filings. Two of the data elements, the container stuffing location and the consolidator, only exist once the box is packed.
What Anxin does: We send the importer's ISF filer the stuffing location, consolidator and manufacturer details as soon as the container is packed in Xiamen, ahead of the vessel's loading window.
- Import country
The emergency response number has to be answered live
US rules want a numeric emergency response telephone number on the shipping paper for battery cargo that leaves Searsport by road, monitored for as long as the goods are in transport and answered by a person with the emergency information for UN3480 or UN3090. A call-back service fails the test (49 CFR 172.604); only the IMDG waiver for cargo that never touches a public highway avoids it.
What Anxin does: Before sailing we confirm who provides the 24-hour number for the US leg, usually the importer's emergency response provider, and put it with the contract reference on the DG documents we send to the trucker.
- Import country
'China' has to be marked on each article or its container
19 CFR 134.11 requires every imported article, or its container, to carry the English name of the country of origin in a conspicuous place, as legibly, indelibly and permanently as the article allows, at the time it is imported. Batteries and battery products reaching Searsport without it can be held until they are marked.
What Anxin does: We check product and carton photos for a durable 'Made in China' marking before stuffing in Xiamen, rather than leaving it for re-marking in a US warehouse.
Documents & compliance
What to have ready: Xiamen to Searsport
Test reports, safety data sheets and import certificates come from the shipper, factory and importer, not from Anxin; our part is to review them before booking.
At the Xiamen end
- For ESS: carriage type (container ship or multipurpose), class 9 terminal and pre-voyage meeting confirmed
- 'Made in China' marking on articles or containers checked on photos
- Safety data sheet and dangerous goods safe-carriage declaration for the MSA cargo report
- Customs packaging use-appraisal result for the dangerous goods packaging (with the maker's performance appraisal)
- Container packing certificate signed by a certified packing inspector after supervised stuffing
Carrier and voyage
- Canal routing and any canal-related surcharge confirmed for the booked vessel
- Lithium battery mark (SP188 cargo) or class 9 labels and placards
- Condition statement: new, used, damaged/defective (SP376) or for recycling (SP377)
For import into United States
- ISF filer named; stuffing location and consolidator sent right after packing
- HTSUS classification from the broker (8507.60.0010 vs .0020 decides the Section 301 line)
- Supply-chain tracing file for cells and lithium inputs, in case of a UFLPA request
Before you book
Send the file once, complete
Most delays on this route start with a document that exists but does not match: a UN number, a model name or a package count that differs between the Xiamen filings, the carrier booking and the United States import file. We check the three against each other before the booking is confirmed.
Carriers we book with
Our booking panel; availability on this lane and acceptance of the declared UN numbers are confirmed for each booking. It does not mean that a listed carrier runs a direct service on this route. Carrier choice depends on the trade lane, cargo classification and each carrier's dangerous-goods acceptance at booking. The final carrier is confirmed on the booking.
Risk & mitigation
Risk table for Xiamen → Searsport
| Risk | Where | Mitigation | Who acts |
|---|---|---|---|
| ESS unit arrives at a terminal without class 9 qualification | Xiamen port | Qualified terminal confirmed at booking | Anxin with the carrier |
| Late or inaccurate ISF | Before loading abroad | Stuffing and consolidator data sent to the ISF filer immediately after packing | Anxin with the ISF filer |
| Truck stopped without a monitored emergency number | Road leg from the port | Emergency response provider confirmed before sailing | Importer, checked by Anxin |
Questions
Questions about shipping from Xiamen to Searsport
Yes. Under 49 CFR 171.25(b)(3), SP188 packages of UN3480 or UN3090 need the 'FORBIDDEN FOR TRANSPORT ABOARD PASSENGER AIRCRAFT' marking or a Cargo Aircraft Only label, and so do packages of batteries packed with or contained in equipment above 5 kg net. We check for it on carton photos before stuffing.
1 June to 30 November, peaking around 10 September, according to the US National Hurricane Center.
Yes. Xiamen MSA reported 104 ESS containers of 36 tonnes each loaded for Houston in June 2026. Xiamen's ESS guide 2.0 requires a pre-voyage meeting and use of a class 9 qualified terminal.
