Lithium batteries for Texas City go through Xiamen, the port for more than 90% of Fujian's lithium battery exports. On the way they face the Pacific, the Panama Canal and the Caribbean, and they arrive at the port of Texas City.
The US side starts with two filings due before loading and ends with a road leg that must carry a live emergency number. The 5 points below are particular to this lane; each comes with what we do and the paperwork it touches.
What we need to start
Route profile
Gatun Lake levels set how much a ship can load through Panama; the Caribbean leg then crosses hurricane waters from June to November.
From ISF and AMS in China to a monitored emergency number on the US truck leg, with Section 301 and UFLPA shaping what arrives.


Where this route gets difficult
They run from the Xiamen terminal through the voyage to Texas City and the United States import file.
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.
Ships leaving Xiamen enter the Taiwan Strait straight away. A Chinese government weather account notes that the strait's funnel effect makes winds 1–2 Beaufort levels stronger than outside it, and that the winter and spring north-east monsoon brings force 7 or stronger winds on about two-thirds of days. Container ships are advised to secure lashing.
What Anxin does: From October to April we apply the CINS blocking and bracing checks strictly on stuffing photos before sealing.
The Panama Canal Authority sets the maximum draft in the Neopanamax locks according to Gatun Lake levels. In September 2026 it postponed a planned cut from 14.63 m to 14.48 m that was due on 1 October (advisory A-33-2026). A lower limit means ships transiting the new locks can load less.
What Anxin does: We check the canal advisory in force when we quote for Texas City and ask carriers to confirm that the booked vessel's routing and any canal surcharge will not change before sailing.
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 Texas City, so the importer can answer CPSC questions quickly.
Since August 2025 lithium has been a high-priority sector under the Uyghur Forced Labor Prevention Act, and CBP had by then stopped more than 16,700 shipments for UFLPA review. A container for Texas City can be held while the importer shows where the cells, cathode material and lithium compounds were sourced.
What Anxin does: We tell the importer at quotation stage that supply-chain tracing may be requested, and keep manufacturer names and addresses consistent across invoice, packing list and ISF so the paper trail does not contradict itself.

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.

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 Texas City.
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 |
|---|---|---|---|
| Cargo shift in winter monsoon seas | Taiwan Strait, Oct–Apr | CINS blocking and bracing checked on photos | Packing site, checked by Anxin |
| Application fails pre-review and falls back to on-site inspection | Xiamen Customs | Data checked against the application first | Anxin with the manufacturer |
| Draft cut reduces capacity or adds surcharges | Panama Canal | Advisory checked at quotation; carrier confirmation | Carrier, checked by Anxin |
| UFLPA detention pending supply-chain evidence | CBP at entry | Importer prepares tracing documents before shipping; consistent manufacturer data on all documents | Importer |
Questions
No. The carrier must also send its cargo declaration through AMS 24 hours before loading, and CBP will not issue the permit to unlade without it.
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.
