This route runs from northern Jiangsu through Lianyungang on the Yellow Sea, then follows a great-circle crossing of the North Pacific; at the far end is the port of Bremerton.
US entry is decided as much by paperwork filed in China as by anything at the port. Below are 6 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
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 North Pacific crossing with no canal or chokepoint risk, but with a record of winter storms strong enough to collapse container stacks.


Where this route gets difficult
Listed from loading in Lianyungang to import into United States, each with what we do about it.
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.
Lianyungang MSA's Notice No. 1 of 2024 cut the materials for 'new three' cargo to four on the cargo side: the safe-carriage declaration, the inspector-signed packing certificate, the packaging inspection certificate where packaged, and a power of attorney. Fewer papers means each one carries more weight; the packing certificate still has to be signed by a certified inspector after supervised stuffing.
What Anxin does: We prepare the four cargo-side documents together and check that the packing certificate, the packaging certificate and the declaration describe the same UN numbers and quantities.
NOAA's Ocean Prediction Center has recorded hurricane-force winds (64 knots or more) in mid-latitude North Pacific storms in every month from October to April, most often in December, with 15 to 23 such storms a season in its 2001–2004 study. These are not tropical systems, so they arrive outside typhoon season.
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.
A container landed at Bremerton without a release permit may stay at the terminal only until the 15th calendar day. The carrier must then notify CBP and a bonded general order warehouse, which moves and stores the goods at the consignee's risk and expense (19 CFR 4.37). Not every general order warehouse can take Class 9 battery cargo, and where specialized storage is missing the port director decides where it goes.
What Anxin does: We check with the importer's broker that the entry can be filed before arrival at Bremerton, and chase any missing invoice or HTS detail while the ship is still at sea.
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 Lianyungang, ahead of the vessel's loading window.
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 Bremerton 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
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 Bremerton.
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 |
| One of the four documents inconsistent with the others | Lianyungang MSA filing | Cross-check before submission | Anxin with the declarant |
| Heavy-weather damage in a winter storm | North Pacific, Oct–Apr | CINS stuffing checks | Packing site, 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
Yes, if the container moves on a public highway. The IMDG waiver in 49 CFR 171.25(d)(2) only covers cargo that stays on the ship or moves between vessels; otherwise 49 CFR 172.604 requires a monitored number answered by someone with the emergency information. Goods shipped as 'Battery powered equipment' are exempt.
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 → Bremerton before any booking, and ask for missing battery documents first.
