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.

From Shanghai to Pascagoula, cargo moves out of Shanghai, crosses a corridor through the Panama Canal, and is discharged at the port of Pascagoula.
The United States applies Section 301 and UFLPA scrutiny to Chinese lithium batteries and wants its manifest data before loading. 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

What sets Shanghai → Pascagoula 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
5 points to plan for on the Shanghai → Pascagoula route
They run from the Shanghai terminal through the voyage to Pascagoula and the United States import file.
- Origin port
Fire-rating proof for Shanghai stuffing warehouses
Under Shanghai MSA's 2024 draft reporting guide, a warehouse stuffing lithium battery dangerous goods must hold fire-department proof of its fire hazard class and fire-resistance rating, and keep its details current on the Shanghai single window, which took over MSA account and site records in 2026.
What Anxin does: We only propose stuffing sites that can show the fire-safety documents and are on Shanghai MSA's system; if you use your own warehouse, we check this before booking.
- Sea corridor
Hurricane season on the Caribbean side
The Atlantic hurricane season, covering the Caribbean and the Gulf of America, runs from 1 June to 30 November, peaking around 10 September, with an average of 14 named storms. Ports on the way to Pascagoula close ahead of storms, and ships wait or divert.
What Anxin does: For August–October arrivals we build slack into delivery plans and pass the carrier's revised arrival straight to your consignee.
- Import country
UFLPA: lithium became a high-priority sector in August 2025
DHS added lithium to the Uyghur Forced Labor Prevention Act high-priority sectors in August 2025. By then CBP had stopped more than 16,700 shipments for UFLPA examination. For battery importers the practical effect is that CBP can ask where cells, cathode and lithium compounds came from, and a shipment waits while the importer answers.
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
The ISF deadline falls before the box is loaded
CBP must have the Importer Security Filing 24 hours before the container is laden in Shanghai, and its liquidated damages guidelines provide for a claim for each late, inaccurate or incomplete filing. The stuffing location and consolidator can only be filled in once the container is packed, which leaves a short window.
What Anxin does: We send the importer's ISF filer the stuffing location, consolidator and manufacturer details as soon as the container is packed in Shanghai, ahead of the vessel's loading window.
- Import country
Unentered battery containers go to General Order after 15 days
A container landed at Pascagoula without a release permit may stay at the terminal only until the 15th calendar day. The carrier must then notify CBP and a bonded general order warehouse, which moves and stores the goods at the consignee's risk and expense (19 CFR 4.37). Not every general order warehouse can take Class 9 battery cargo, and where specialized storage is missing the port director decides where it goes.
What Anxin does: We check with the importer's broker that the entry can be filed before arrival at Pascagoula, and chase any missing invoice or HTS detail while the ship is still at sea.

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
Risks on this route and who deals with them

| UFLPA detention pending supply-chain evidence | CBP at entry | Importer prepares tracing documents before shipping; consistent manufacturer data on all documents | Importer |
| Late or inaccurate ISF | Before loading abroad | Stuffing and consolidator data sent to the ISF filer immediately after packing | Anxin with the ISF filer |
Questions
Common questions on the Shanghai → Pascagoula 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.
1 June to 30 November, peaking around 10 September, according to the US National Hurricane Center.
It can, but Shanghai MSA checks the phone location of the packing photos against a verified stuffing site, and sites outside Shanghai must be registered with it. We confirm registration before the stuffing date; otherwise the container can be refused for loading.
