From Xiamen to Washington DC, cargo moves from Fujian's battery makers through Xiamen port, crosses a corridor through the Panama Canal, and is discharged at the port of Washington DC.
Washington DC means US customs filings that are due while the container is still in Xiamen, and a supply chain CBP may ask to see. 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
Route profile
A Panama Canal corridor whose Neopanamax draft depends on Gatun Lake levels, followed by the Caribbean during hurricane season.
US entry hinges on filings made in China (ISF and AMS), a traceable lithium supply chain and a road leg that is regulated as a hazmat move.


Where this route gets difficult
Listed from loading in Xiamen to import into United States, each with what we do about it.
Xiamen Customs now issues the packaging use-appraisal certificate for lithium batteries through the single window after automatic pre-review matching: about 10 minutes in the case reported in August 2026, against roughly half a day for the old on-site inspection. The fast path is only for products that pass pre-review as compliant and valid; anything that does not match goes back to inspection.
What Anxin does: We check the product data, UN38.3 summary and packaging codes against the application before it is submitted, so the certificate comes through pre-review rather than falling back to an on-site check.
The last leg north to Washington DC 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.
US customs rules give an unentered container 15 calendar days at the place of unlading. After that the carrier hands it to a bonded general order warehouse, with transport and storage at the consignee's risk and expense, and for DG cargo that needs specialized storage the port director decides where it is kept (19 CFR 4.37).
What Anxin does: We check with the importer's broker that the entry can be filed before arrival at Washington DC, and chase any missing invoice or HTS detail while the ship is still at sea.
US importers, like manufacturers and retailers, must tell CPSC within 24 hours once they have information reasonably suggesting that a consumer product fails a safety rule or has a defect that could create a substantial hazard. Battery overheating reports from customers can trigger that duty, and CPSC expects any investigation to take no more than about 10 working days.
What Anxin does: We keep the manufacturer's batch records, UN 38.3 summaries and packing photos for each shipment to Washington DC, so the importer can answer CPSC questions quickly.
Battery containers held for DG checks or paperwork can run up demurrage and detention at Washington DC. Under the FMC's billing rule, in force since May 2024, carriers and terminals must invoice within 30 days with accurate, complete information, or the charge is not payable, and the billed party has at least 30 days to ask for a waiver or refund. A 2025 court ruling set aside only the section on who may be billed.
What Anxin does: We keep the dates of discharge, availability and any DG hold for each container, so the importer can check invoices against them and dispute charges inside the FMC time limits.

Documents & compliance
These documents come from the shipper, the manufacturer and the importer. Anxin checks them against each other; it does not issue test reports, safety data sheets or import certificates.

We line up UN numbers, model names and package counts across the Xiamen filings, the booking with the carrier and the documents for United States before the booking is confirmed, so that a mismatch is fixed at origin rather than discovered at Washington DC.
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 | Where | Mitigation | Who acts |
|---|---|---|---|
| Application fails pre-review and falls back to on-site inspection | Xiamen Customs | Data checked against the application first | Anxin with the manufacturer |
Questions
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.
It can. In September 2026 the Panama Canal Authority postponed a planned draft cut in the Neopanamax locks because of Gatun Lake levels (advisory A-33-2026). We check the advisory in force when quoting.
For products that pass automatic pre-review, Xiamen Customs issues it through the single window; the case reported in August 2026 took about 10 minutes, against about half a day for the old on-site inspection. Products that do not pass pre-review still need inspection.
