Xiamen (Haicang / Songyu)
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.

Xiamen to Coos Bay
Taiwan Strait · East China Sea · North Pacific
Lithium batteries for Coos Bay go out of Xiamen's Haicang and Songyu terminals on the Taiwan Strait. On the way they face a great-circle crossing of the North Pacific, and they arrive at the port of Coos Bay.
The US side starts with two filings due before loading and ends with a road leg that must carry a live emergency number. This page sets out 6 points specific to this route, how Anxin handles each one and which documents to prepare.
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.
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
Listed from loading in Xiamen to import into United States, each with what we do about it.
Through the single window, Xiamen Customs now issues the lithium battery packaging use-appraisal certificate after automatic pre-review matching: roughly 10 minutes in a case reported in August 2026, compared with about half a day for the former on-site inspection. Only products that pass pre-review as compliant and valid get the fast path; mismatches return 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.
Leaving Xiamen, ships are in the Taiwan Strait at once. A Chinese government weather account says the strait's funnel effect adds 1–2 Beaufort levels to the wind, and that the north-east monsoon of winter and spring brings force 7 or more on about two days in three. Lashing on container ships should be secured accordingly.
What Anxin does: From October to April we apply the CINS blocking and bracing checks strictly on stuffing photos before sealing.
From Xiamen the drawn corridor to Coos Bay runs across the North Pacific without a canal or Red Sea passage, so weather replaces chokepoints as the risk. The ONE Apus, bound from Yantian to Long Beach in November 2020, had a stack collapse in a storm about 1,600 nautical miles north-west of Hawaii; her owners said more than 1,900 containers could be lost or damaged, up to 40 of them hazmat.
What Anxin does: For winter sailings especially, we review blocking and bracing on stuffing photos against the CINS points before sealing, and make sure the DG declaration is complete, so a damaged box can be identified and handled correctly.
USTR's 2024 review moved lithium-ion batteries of HTSUS 8507.60.0020 (the 'other', non-passenger-EV line) from a 7.5% to a 25% additional duty for entries from 1 January 2026; EV traction batteries under 8507.60.0010 reached 25% in 2024. Other China-specific duties can stack on top and change with little notice, so the landed cost depends on the exact classification and entry date.
What Anxin does: We do not give duty rulings. We make sure the invoice describes chemistry, configuration and application precisely enough for the importer's customs broker to classify it, and we flag the entry date when a vessel's arrival could straddle a duty change.
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.
Since 8 July 2026, importers of consumer products that are subject to a CPSC certification requirement must electronically file the certificate data at entry; goods entered from a Foreign Trade Zone follow on 8 January 2027. Whether a battery-powered product is caught depends on the rules that apply to that product, not on the battery alone.
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
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.

A document that is present but inconsistent holds a booking as surely as a missing one: the UN number, model name or carton count reads differently in the Xiamen export filings, the carrier booking and the United States import papers. We compare all three before confirming space.
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 |
| Stack collapse or cargo shift in a North Pacific storm | Mid-Pacific | Blocking and bracing checked before sealing; complete DG data for incident response | Packing site / carrier, checked by Anxin |
| 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
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.
Weather is the main risk on this crossing: NOAA recorded hurricane-force North Pacific storms from October to April, most often in December. We tighten the packing checks for those sailings.
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.
