Shanghai (Yangshan / Waigaoqiao)
Yangshan and Waigaoqiao exports under Shanghai MSA's photo-verified packing system, where a mismatch between photos and EDI data keeps a DG box off the ship.

Lithium batteries for Anchorage go through Yangshan or Waigaoqiao under Shanghai MSA's photo-verified packing rules. On the way they face a great-circle crossing of the North Pacific, and they arrive at the port of Anchorage.
US entry is decided as much by paperwork filed in China as by anything at the port. 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
- Yangshan / Waigaoqiao export
- Photo-verified packing certificate
- Supply-chain tracing file
- HTS code 8507.60
- ISF filer
Route profile
The Shanghai → Anchorage route in brief
Transpacific (North Pacific)
No canal or Red Sea passage, but a North Pacific crossing where winter storms have collapsed container stacks.
Where this route gets difficult
Where Shanghai → Anchorage shipments get held up: 5 points
In the order the cargo meets them: at the loading port, at sea, at Anchorage and at customs in United States.
- 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
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
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 Anchorage 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
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 Anchorage 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
Demurrage and detention invoices must follow FMC rules
Battery containers held for DG checks or paperwork can run up demurrage and detention at Anchorage. 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
Documents to line up for Shanghai → Anchorage
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
- 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
- Transport-condition classification report where applicable
For the shipping line
- Stuffing photos before, during and after packing, checked for blocking and bracing
- Condition statement: new, used, damaged/defective (SP376) or for recycling (SP377)
- SP188 cartons: US 'forbidden aboard passenger aircraft' marking or CAO label
For import into United States
- Supply-chain tracing file for cells and lithium inputs, in case of a UFLPA request
- CPSC certificate data and eFiling arrangement, if the product is subject to certification
- 24-hour emergency response number (and provider reference) for the US road leg
Before you book
One consistent file
A document that is present but inconsistent holds a booking as surely as a missing one: the UN number, model name or carton count reads differently in the Shanghai export filings, the carrier booking and the United States import papers. We compare all three before confirming space.
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 table for Shanghai → Anchorage
| Risk | Where | Mitigation | Who acts |
|---|---|---|---|
| Post-event spot check finds missing proof | Shanghai MSA | Evidence file kept per container | Shipper with Anxin |
| 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
Common questions on the Shanghai → Anchorage route
Yes. Under 49 CFR 171.25(b)(3), SP188 packages of UN3480 or UN3090 need the 'FORBIDDEN FOR TRANSPORT ABOARD PASSENGER AIRCRAFT' marking or a Cargo Aircraft Only label, and so do packages of batteries packed with or contained in equipment above 5 kg net. We check for it on carton photos before stuffing.
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.
