From Lianyungang to Seattle, cargo moves from northern Jiangsu through Lianyungang on the Yellow Sea, crosses a North Pacific corridor with no canal or chokepoint, and is discharged at the port of Seattle.
US entry is decided as much by paperwork filed in China as by anything at the port. The 6 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
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.
No canal or Red Sea passage, but a North Pacific crossing where winter storms have collapsed container stacks.


Where this route gets difficult
They run from the Lianyungang terminal through the voyage to Seattle and the United States import file.
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.
The China Meteorological Administration describes sea fog as a major marine hazard in the Yellow and Bohai Seas, mainly from April to July. At Lianyungang, as at Qingdao, fog can hold vessels at anchor, and a changed vessel means amended DG filings.
What Anxin does: In fog season we keep slack between stuffing and the DG cut-off and have the filing data ready to amend.
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.
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.
Besides the importer's ISF, CBP must receive the carrier's electronic cargo declaration through AMS 24 hours before the container is laden in Lianyungang (19 CFR 4.7). CBP does not issue the permit to unlade at Seattle until it has that declaration, and late, incomplete or inaccurate cargo data can delay or deny it.
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 Lianyungang, so the AMS filing and the DG manifest say the same thing.
From 1 January 2027 producers selling covered batteries or battery-containing products in or into Washington must be in an approved stewardship plan through a battery stewardship organization, or they may not sell there (RCW 70A.555). From 1 July 2027 retailers may not stock portable batteries unless the producer certifies it participates.
What Anxin does: When cargo through Seattle 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
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.

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 Lianyungang 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 |
|---|---|---|---|
| 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 |
| 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, 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.
Under its Notice No. 1 of 2024, the cargo side submits the DG safe-carriage declaration, the inspector-signed packing certificate, the packaging inspection certificate where the goods are packaged, and a power of attorney.

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