Transpacific (North Pacific)
No canal or Red Sea passage, but a North Pacific crossing where winter storms have collapsed container stacks.

Lithium batteries for Anacortes go through Ningbo-Zhoushan, where Zhejiang MSA's guide sets a 60% weight-balance test for battery containers. On the way they face a great-circle crossing of the North Pacific, and they arrive at the port of Anacortes.
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
- Zhejiang MSA battery guide 2026
- Beilun / Meishan export
- Supply-chain tracing file

Route profile
How Ningbo → Anacortes differs from other lanes
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 Ningbo → Anacortes shipments get held up: 6 points
Listed from loading in Ningbo to import into United States, each with what we do about it.
- Origin port
Weight balance and stowage under Zhejiang's guide
Zhejiang MSA's January 2026 guide gives a measurable loading rule: neither half of the container's length may hold more than 60% of the cargo weight, and packages must be braced. On deck, battery boxes should sit within fire-fighting coverage and out of direct sun; below deck, in holds fitted with temperature probes.
What Anxin does: We ask for the load plan before stuffing and check the 60% split on the stuffing photos, and we pass the shading and away-from-heat stowage request to the carrier on the booking.
- Origin port
River-to-sea feeders into Ningbo: file the cargo report once
For battery cargo moving water-to-water, Zhejiang MSA applies a 'one-document' rule: when the cargo report is filed at the loading port, the transhipment port only needs a ship report. Batteries barged into Ningbo can skip a second cargo report, as long as the first was correct.
What Anxin does: When cargo starts on a feeder or barge, we make sure the cargo report is filed at the first port of loading and carries the ocean routing, so no second cargo report is needed at Ningbo.
- Sea corridor
Winter storms with hurricane-force winds
NOAA's Ocean Prediction Center found hurricane-force winds (64 knots and above) in North Pacific mid-latitude storms in every month from October to April, peaking in December, with 15 to 23 such storms per season in its 2001–2004 records. They are not typhoons, so they do not follow the tropical calendar.
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.
- Import country
The carrier's AMS manifest is due 24 hours before loading
Besides the importer's ISF, CBP must receive the carrier's electronic cargo declaration through AMS 24 hours before the container is laden in Ningbo (19 CFR 4.7). CBP does not issue the permit to unlade at Anacortes 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 Ningbo, so the AMS filing and the DG manifest say the same thing.
- 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
CPSC certificate data now filed at entry
Since 8 July 2026, importers of consumer products that are subject to a CPSC certification requirement must electronically file the certificate data at entry; goods entered from a Foreign Trade Zone follow on 8 January 2027. Whether a battery-powered product is caught depends on the rules that apply to that product, not on the battery alone.
What Anxin does: We ask whether the goods are consumer products that need a CPSC certificate and, if so, who files it, so that the question is settled before the goods arrive.
Documents & compliance
What to have ready: Ningbo to Anacortes
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.
Before loading in Ningbo
- Load plan showing no half of the container carries more than 60% of the weight
- '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 carrier and the voyage
- 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)
At the United States end
- CPSC certificate data and eFiling arrangement, if the product is subject to certification
- Supply-chain tracing file for cells and lithium inputs, in case of a UFLPA request
- 24-hour emergency response number (and provider reference) for the US road leg
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 Ningbo 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 |
|---|---|---|---|
| Uneven load rejected at the Ningbo packing check | Beilun / Meishan stuffing | Load plan checked before stuffing | Packing site, checked by Anxin |
| Heavy-weather damage in a winter storm | North Pacific, Oct–Apr | CINS stuffing checks | Packing site, 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
Questions about shipping from Ningbo to Anacortes
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.
Zhejiang MSA's 2026 guide says the cargo weight in any half of the container's length should not exceed 60% of the total, with every package braced and checked for damage and marks.
