Transpacific (North Pacific)
A great-circle route across the North Pacific, exposed to hurricane-force winter storms from October to April.
North America · sea freight from Lianyungang
Lianyungang to Valdez
Yellow Sea · Korea Strait · Sea of Japan · Tsugaru Strait · Aleutians · Gulf of Alaska
This route runs through Lianyungang port, then follows the open North Pacific, where weather is the main risk; at the far end is the port of Valdez.
The US side starts with two filings due before loading and ends with a road leg that must carry a live emergency number. The 5 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
A great-circle route across the North Pacific, exposed to hurricane-force winter storms from October to April.
Two filings before loading, a Section 301 line set by classification, UFLPA supply-chain questions and a 15-day General Order clock after discharge.


Where this route gets difficult
In the order the cargo meets them: at the loading port, at sea, at Valdez and at customs in United States.
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.
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 Valdez 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.
US rules want a numeric emergency response telephone number on the shipping paper for battery cargo that leaves Valdez by road, monitored for as long as the goods are in transport and answered by a person with the emergency information for UN3480 or UN3090. A call-back service fails the test (49 CFR 172.604); only the IMDG waiver for cargo that never touches a public highway avoids it.
What Anxin does: Before sailing we confirm who provides the 24-hour number for the US leg, usually the importer's emergency response provider, and put it with the contract reference on the DG documents we send to the trucker.
Battery containers held for DG checks or paperwork can run up demurrage and detention at Valdez. Under the FMC's billing rule, in force since May 2024, carriers and terminals must invoice within 30 days with accurate, complete information, or the charge is not payable, and the billed party has at least 30 days to ask for a waiver or refund. A 2025 court ruling set aside only the section on who may be billed.
What Anxin does: We keep the dates of discharge, availability and any DG hold for each container, so the importer can check invoices against them and dispute charges inside the FMC time limits.

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.

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 Valdez.
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 |
| Truck stopped without a monitored emergency number | Road leg from the port | Emergency response provider confirmed before sailing | Importer, checked by 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 → Valdez before any booking, and ask for missing battery documents first.
