From Xiamen to Houston, cargo moves out of Xiamen's Haicang and Songyu terminals on the Taiwan Strait, crosses a Pacific crossing and a Panama Canal transit, and is discharged at the port of Houston.
Houston means US customs filings that are due while the container is still in Xiamen, and a supply chain CBP may ask to see. Below are 5 route-specific points to plan for, what we do about each, and the documents to have ready before booking.
What we need to start
Route profile
Fujian's battery gateway, handling more than 90% of the province's lithium battery exports, with 10-minute online packaging appraisal for compliant products and the Taiwan Strait's winter monsoon on the doorstep.
A Pacific crossing, a Panama Canal transit that depends on lake levels, and a Caribbean passage in hurricane season.


Where this route gets difficult
Listed from loading in Xiamen to import into United States, each with what we do about it.
For large battery consignments Xiamen MSA offers pre-review of key DG documents, a pre-loading meeting where ship, cargo owner, terminal and agent agree deck stowage and emergency measures, and a 'one ship, one plan' checklist from gate-in to departure. In June 2026 it reported 104 energy-storage containers of 36 tonnes each loaded on a multipurpose ship for Houston.
What Anxin does: We send the key documents for pre-review before the formal filing and bring the stowage and emergency details the meeting will ask for.
The first half of the voyage crosses the North Pacific, where NOAA has recorded hurricane-force mid-latitude storms from October to April, most often in December.
What Anxin does: For October–April sailings we check blocking and bracing on stuffing photos before sealing.
CBP must have the Importer Security Filing 24 hours before the container is laden in Xiamen, and its liquidated damages guidelines provide for a claim for each late, inaccurate or incomplete filing. The stuffing location and consolidator can only be filled in once the container is packed, which leaves a short window.
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.
Bayport and Barbours Cut use a paperless hazardous pre-advise system. The shipping line submits the DG documents, the trucker's ExpressPass carries a Haz_No_Ingate hold until the hazardous team approves the unit, and papers handed over at the gate are refused.
What Anxin does: We make sure the carrier has the final DG documents for Houston well before arrival and tell the trucker to check that the hold is released in Lynx before sending a driver.
Consumer products that need a CPSC certificate have had their certificate data filed electronically at entry since 8 July 2026 (goods from a Foreign Trade Zone from 8 January 2027). A battery-powered product falls under it through the product's own rules, which the importer should settle before the goods reach Houston.
What Anxin does: We ask whether the goods are consumer products that need a CPSC certificate and, if so, who files it, so that the question is settled before the goods arrive.

Documents & compliance
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.

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 | Where | Mitigation | Who acts |
|---|---|---|---|
| Late or inaccurate ISF | Before loading abroad | Stuffing and consolidator data sent to the ISF filer immediately after packing | Anxin with the ISF filer |
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.
1 June to 30 November, peaking around 10 September, according to the US National Hurricane Center.
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.
