This route runs from northern Jiangsu through Lianyungang on the Yellow Sea, then follows a North Pacific crossing with no chokepoint but real winter-storm exposure; at the far end is the port of Coos Bay.
The US side adds a 25% Section 301 duty line, forced-labour scrutiny of lithium supply chains and an ISF deadline that falls before loading. 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
Jiangsu's Yellow Sea port, with a simplified document list for 'new three' cargo since 2024 and its own guide for energy-storage units on break-bulk ships.
A duty line set by the exact 8507.60 code, lithium supply-chain questions under UFLPA, and ISF and AMS filings that are due before the box is loaded.


Where this route gets difficult
In the order the cargo meets them: at the loading port, at sea, at Coos Bay and at customs in United States.
For energy storage shipped on break-bulk vessels, Lianyungang MSA's June 2025 guide classes ESS cabinets as UN3480 and ESS containers as UN3536, recommends 20–50% remaining charge, and requires converters and monitoring switched off, series and parallel circuits disconnected, packages spread evenly with a low centre of gravity, and a safety meeting before the ship arrives.
What Anxin does: For ESS units we confirm the UN number the unit ships under, get the state of charge and isolation steps in writing from the manufacturer, and join the pre-arrival safety meeting with the stowage details.
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.
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 Coos Bay 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.
For lithium-ion batteries entered from 1 January 2026 USTR set the Section 301 additional duty on HTSUS 8507.60.0020 (the non-EV line) at 25%, the level EV batteries under 8507.60.0010 reached in 2024. Other China-specific duties can be added and change at short notice, so the classification and the entry date both move the landed cost at Coos Bay.
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.
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 Coos Bay, so the importer can answer CPSC questions quickly.

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 Lianyungang 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 Coos Bay.
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 |
|---|---|---|---|
| ESS unit not isolated or poorly distributed in a break-bulk hold | Lianyungang, break-bulk loading | Manufacturer's written isolation steps; safety meeting | Manufacturer / ship, coordinated 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 |
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.
Its June 2025 break-bulk ESS guide recommends 20–50% remaining charge, with converters and monitoring off and circuits disconnected.

We check carrier acceptance for Lianyungang → Coos Bay before any booking, and ask for missing battery documents first.
