Transpacific (North Pacific)
A North Pacific crossing with no canal or chokepoint risk, but with a record of winter storms strong enough to collapse container stacks.

From Shanghai to Valdez, cargo moves through Yangshan or Waigaoqiao under Shanghai MSA's photo-verified packing rules, crosses a North Pacific corridor with no canal or chokepoint, and is discharged at 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
- Photo-verified packing certificate
- Yangshan / Waigaoqiao export
- ISF filer
- Supply-chain tracing file
- HTS code 8507.60
Route profile
The Shanghai → Valdez route in brief
United States
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
Where Shanghai → Valdez shipments get held up: 5 points
Loading port first, then the sea leg, then Valdez and the United States market.
- Origin port
Shanghai checks during and after the voyage filing, not just before
Shanghai MSA's Notice No. 4 of 2024 accepts either an inspector-signed packing certificate or a packing declaration from the stuffing company, but places the burden on the shipper: the batteries must meet the UN tests and be protected against damage, short circuit and accidental activation, and MSA runs spot checks during and after the process, with proof to be produced on request.
What Anxin does: We keep a file per container (UN38.3 summary, SDS, packing photos, terminal protection details) so that proof can be produced the same day if Shanghai MSA asks for it after sailing.
- Sea corridor
An open-ocean crossing where weather is the main risk
From Shanghai the drawn corridor to Valdez runs across the North Pacific without a canal or Red Sea passage, so weather replaces chokepoints as the risk. The ONE Apus, bound from Yantian to Long Beach in November 2020, had a stack collapse in a storm about 1,600 nautical miles north-west of Hawaii; her owners said more than 1,900 containers could be lost or damaged, up to 40 of them hazmat.
What Anxin does: For winter sailings especially, we review blocking and bracing on stuffing photos against the CINS points before sealing, and make sure the DG declaration is complete, so a damaged box can be identified and handled correctly.
- Import country
AMS: the manifest CBP sees before the ship leaves Shanghai
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 Valdez 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 Shanghai, so the AMS filing and the DG manifest say the same thing.
- Import country
Day 15 at the terminal: the General Order deadline
US customs rules give an unentered container 15 calendar days at the place of unlading. After that the carrier hands it to a bonded general order warehouse, with transport and storage at the consignee's risk and expense, and for DG cargo that needs specialized storage the port director decides where it is kept (19 CFR 4.37).
What Anxin does: We check with the importer's broker that the entry can be filed before arrival at Valdez, and chase any missing invoice or HTS detail while the ship is still at sea.
- Import country
Demurrage and detention invoices must follow FMC rules
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
What to have ready: Shanghai to Valdez
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.
At the Shanghai end
- Per-container evidence file (UN38.3 summary, SDS, photos, short-circuit protection) kept for Shanghai MSA spot checks
- 'Made in China' marking on articles or containers checked on photos
- Safety data sheet and dangerous goods safe-carriage declaration for the MSA cargo report
- Customs packaging use-appraisal result for the dangerous goods packaging (with the maker's performance appraisal)
- Container packing certificate signed by a certified packing inspector after supervised stuffing
For the shipping line
- Stuffing photos before, during and after packing, checked for blocking and bracing
- UN 38.3 test summary for every cell and battery type
- Dangerous goods declaration with UN number (3480 / 3481 / 3090 / 3091), proper shipping name and packing instruction (P903, or P908/P911 for damaged)
For import into United States
- Importer of record and the licensed customs broker who will file the entry
- ISF filer named; stuffing location and consolidator sent right after packing
Before you book
Send the file once, complete
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 Shanghai 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
Risks on this route and who deals with them
| Risk | Where | Mitigation | Who acts |
|---|---|---|---|
| Post-event spot check finds missing proof | Shanghai MSA | Evidence file kept per container | Shipper with Anxin |
| Stack collapse or cargo shift in a North Pacific storm | Mid-Pacific | Blocking and bracing checked before sealing; complete DG data for incident response | Packing site / carrier, checked by Anxin |
| 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
Common questions on the Shanghai → Valdez route
For lithium-ion batteries classified in HTSUS 8507.60.0020 and entered from 1 January 2026, USTR set the Section 301 additional duty at 25%; EV traction batteries in 8507.60.0010 have been at 25% since 2024. Other duties can apply on top. The importer's customs broker confirms the classification and total duty; we make sure the invoice gives the broker enough detail to do so.
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.
Shanghai MSA's Notice No. 4 of 2024 accepts either an inspector-signed packing certificate or a packing declaration issued by the stuffing company. Either way, the shipper remains responsible and must provide proof if MSA spot-checks.
