From Lianyungang to Trenton, cargo moves from northern Jiangsu through Lianyungang on the Yellow Sea, crosses a corridor into Atlantic Canada's waters, and is discharged at the port of Trenton.
The US side adds a 25% Section 301 duty line, forced-labour scrutiny of lithium supply chains and an ISF deadline that falls before loading. Below are 5 route-specific points to plan for, what we do about each, and the documents to have ready before booking.

Route profile
What sets Lianyungang → Trenton apart
Asia – Atlantic Canada, the St Lawrence and the North Atlantic
A final leg through North Atlantic or St Lawrence waters, with ice from December to May and winter storms that peak in January.
Where this route gets difficult
Where Lianyungang → Trenton shipments get held up: 5 points
Listed from loading in Lianyungang to import into United States, each with what we do about it.
- Origin port
Fog season at Lianyungang
Between April and July sea fog is a major marine hazard in the Yellow and Bohai Seas, the China Meteorological Administration says. Lianyungang, like Qingdao, can see vessels held at anchor by fog, and moving a box to another vessel means amending its DG filings.
What Anxin does: In fog season we keep slack between stuffing and the DG cut-off and have the filing data ready to amend.
- Sea corridor
Ice in the Gulf of St Lawrence, December to May
The Canadian Coast Guard's icebreaking season on the Gulf of St Lawrence and the St Lawrence River typically runs from December to May, and ships must clear with ECAREG CANADA 24 hours before entering, declaring their ice class. Winter sailings to Trenton depend on the vessel's ice capability and on icebreaker routing.
What Anxin does: For December–May arrivals we ask the carrier whether the vessel or feeder serving Trenton is ice-classed and build slack into delivery.
- Import country
The emergency response number has to be answered live
US rules want a numeric emergency response telephone number on the shipping paper for battery cargo that leaves Trenton by road, monitored for as long as the goods are in transport and answered by a person with the emergency information for UN3480 or UN3090. A call-back service fails the test (49 CFR 172.604); only the IMDG waiver for cargo that never touches a public highway avoids it.
What Anxin does: Before sailing we confirm who provides the 24-hour number for the US leg, usually the importer's emergency response provider, and put it with the contract reference on the DG documents we send to the trucker.
- Import country
AMS: the manifest CBP sees before the ship leaves Lianyungang
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 Trenton 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 Lianyungang, so the AMS filing and the DG manifest say the same thing.
- 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.

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 Lianyungang 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 |
|---|---|---|---|
| Ice delays arrival or limits which vessels can call | Gulf of St Lawrence, Dec–May | Ice-classed vessel confirmed; slack in delivery | Carrier |
| 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 |
| Truck stopped without a monitored emergency number | Road leg from the port | Emergency response provider confirmed before sailing | Importer, checked by Anxin |
Questions
Questions about shipping from Lianyungang to Trenton
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.
Rarely. The Seaway's maximum draft in the Montreal–Lake Ontario section is 8.00 m and it closes in winter (target 5 January 2027 for the 2026 season), so containers usually leave the ocean vessel at a coastal port and continue by smaller ship, rail or truck.
Its June 2025 break-bulk ESS guide recommends 20–50% remaining charge, with converters and monitoring off and circuits disconnected.
