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.
North America · sea freight from Xiamen
Xiamen to Kalama
Taiwan Strait · East China Sea · North Pacific
This route runs through Xiamen, the port for more than 90% of Fujian's lithium battery exports, then follows a great-circle crossing of the North Pacific; at the far end is the port of Kalama.
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 5 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
They run from the Xiamen terminal through the voyage to Kalama and the United States import file.
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.
NOAA's Ocean Prediction Center found hurricane-force winds (64 knots and above) in North Pacific mid-latitude storms in every month from October to April, peaking in December, with 15 to 23 such storms per season in its 2001–2004 records. They are not typhoons, so they do not follow the tropical calendar.
What Anxin does: For October–April sailings we check blocking and bracing on stuffing photos before sealing and confirm the full DG data are on the manifest.
DHS added lithium to the Uyghur Forced Labor Prevention Act high-priority sectors in August 2025. By then CBP had stopped more than 16,700 shipments for UFLPA examination. For battery importers the practical effect is that CBP can ask where cells, cathode and lithium compounds came from, and a shipment waits while the importer answers.
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.
Under 19 CFR 4.7 the carrier's cargo declaration must be in CBP's Automated Manifest System 24 hours before loading abroad. Without it, or with inaccurate data, the permit to unlade the container at Kalama can be delayed or refused.
What Anxin does: We give the carrier or NVOCC the final cargo description, HS code, UN number and package count before the documentation cut-off in Xiamen, so the AMS filing and the DG manifest say the same thing.
Washington's battery law (RCW 70A.555) closes the market to producers outside an approved stewardship organization from 1 January 2027, and from July 2027 retailers need the producer's certification before selling portable batteries or products that contain them.
What Anxin does: When cargo through Kalama is sold in Washington, we flag the 2027 stewardship requirement to the importer at quotation so that retailer certification is in place in time.

Documents & compliance
Anxin reviews documents supplied by the shipper, manufacturer and importer; it does not issue test reports, safety data sheets or import certificates.

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 |
|---|---|---|---|
| Cargo shift in winter monsoon seas | Taiwan Strait, Oct–Apr | CINS blocking and bracing checked on photos | Packing site, checked by Anxin |
| Heavy-weather damage in a winter storm | North Pacific, Oct–Apr | CINS stuffing checks | Packing site, 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 |
| Permit to unlade delayed for a late or inaccurate AMS manifest | Port of discharge | Final cargo data given to the carrier before the cut-off | Carrier / NVOCC, with data from Anxin |
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.
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.
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.
