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.

This route runs out of Shanghai, where MSA spot-checks battery containers during and after filing, then follows a great-circle crossing of the North Pacific; at the far end is the port of Anacortes.
The US side starts with two filings due before loading and ends with a road leg that must carry a live emergency number. 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
- Photo-verified packing certificate
- Yangshan / Waigaoqiao export
- ISF filer
- Supply-chain tracing file
- HTS code 8507.60
Route profile
What sets Shanghai → Anacortes apart
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 → Anacortes shipments get held up: 5 points
Loading port first, then the sea leg, then Anacortes and the United States market.
- Origin port
Shanghai MSA spot-checks after the filing too
Shanghai MSA's Notice No. 4 of 2024 lets the shipper use either an inspector-signed packing certificate or a packing declaration from the stuffing company, but the responsibility stays with the shipper: UN-tested batteries, protected against damage, short circuit and accidental activation. MSA spot-checks during and after the process and can ask for proof.
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
No chokepoint, but North Pacific storms
The drawn corridor from Shanghai crosses the North Pacific, with no canal and no Red Sea exposure. Weather is the risk instead. In November 2020 the ONE Apus, sailing from Yantian to Long Beach, suffered a stack collapse in a storm about 1,600 nautical miles north-west of Hawaii; its owners reported that more than 1,900 containers could be lost or damaged, including up to 40 hazmat boxes.
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
Where the lithium came from: UFLPA questions at entry
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 Anacortes 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.
- Import country
Washington battery stewardship starts in 2027
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 Anacortes is sold in Washington, we flag the 2027 stewardship requirement to the importer at quotation so that retailer certification is in place in time.
- Import country
Product defects must be reported to CPSC within 24 hours
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 Anacortes, so the importer can answer CPSC questions quickly.
Documents & compliance
What to have ready: Shanghai to Anacortes
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.
In Shanghai, before the box is loaded
- 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
- Lithium battery mark (SP188 cargo) or class 9 labels and placards
- Condition statement: new, used, damaged/defective (SP376) or for recycling (SP377)
For the importer in United States
- Supply-chain tracing file for cells and lithium inputs, in case of a UFLPA request
- HTSUS classification from the broker (8507.60.0010 vs .0020 decides the Section 301 line)
- CPSC certificate data and eFiling arrangement, if the product is subject to certification
Before you book
Match the details first
We line up UN numbers, model names and package counts across the Shanghai 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 Anacortes.
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
What could go wrong from Shanghai to Anacortes, and who acts
| 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 |
| UFLPA detention pending supply-chain evidence | CBP at entry | Importer prepares tracing documents before shipping; consistent manufacturer data on all documents | Importer |
Questions
Shanghai → Anacortes: questions we are asked
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.
