This route runs through Xiamen, the port for more than 90% of Fujian's lithium battery exports, then follows a long voyage ending in the North Atlantic or the Gulf of St Lawrence; at the far end is 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.

What we need to start

  • Xiamen export
  • Online packaging appraisal
  • Supply-chain tracing file

Route profile

What sets Xiamen → Trenton apart

Origin port

Xiamen (Haicang / Songyu)

Fujian's battery gateway, handling more than 90% of the province's lithium battery exports, with 10-minute online packaging appraisal for compliant products and the Taiwan Strait's winter monsoon on the doorstep.

Sea corridor

Asia – Atlantic Canada, the St Lawrence and the North Atlantic

The last leg crosses the North Atlantic or enters the Gulf of St Lawrence, with an icebreaking season from December to May and hurricane-force winter storms peaking in January.

Where this route gets difficult

Where Xiamen → Trenton shipments get held up: 5 points

Loading port first, then the sea leg, then Trenton and the United States market.

  1. Origin port

    Xiamen MSA's 'one ship, one plan' for large battery cargo

    Xiamen MSA offers pre-review of key DG documents, a pre-loading meeting at which ship, cargo owner, terminal and agent agree deck stowage and emergency measures, and a 'one ship, one plan' checklist from gate-in to sailing. In June 2026 it reported 104 energy-storage containers of 36 tonnes each loaded for Houston on a multipurpose ship.

    What Anxin does: We send the key documents for pre-review before the formal filing and bring the stowage and emergency details the meeting will ask for.

  2. Sea corridor

    The St Lawrence icebreaking season, December to May

    From December to May the Canadian Coast Guard breaks ice on the Gulf of St Lawrence and the river, and ships must clear with ECAREG CANADA 24 hours before entering, giving their ice class. Whether a winter sailing reaches Trenton on time depends on the ship's ice capability and 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.

  3. Import country

    SP188 packages need an extra US marking

    Small cells and batteries shipped under IMDG special provision 188 do not need a dangerous goods declaration at sea, but 49 CFR 171.25(b)(3) adds a US condition: each package of UN3480 or UN3090 must carry the 'FORBIDDEN FOR TRANSPORT ABOARD PASSENGER AIRCRAFT' marking or a Cargo Aircraft Only label, and so must packages of batteries with or in equipment above 5 kg net. Cartons printed for other markets often lack it.

    What Anxin does: When the shipper declares SP188 for a Trenton booking, we check the carton photos for the US marking or CAO label before stuffing, not after discharge.

  4. 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 Xiamen, 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 Xiamen, ahead of the vessel's loading window.

  5. Import country

    Unentered battery containers go to General Order after 15 days

    A container landed at Trenton 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 Trenton, and chase any missing invoice or HTS detail while the ship is still at sea.

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 Xiamen 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.

Questions

Common questions on the Xiamen → Trenton 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.

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.

For products that pass automatic pre-review, Xiamen Customs issues it through the single window; the case reported in August 2026 took about 10 minutes, against about half a day for the old on-site inspection. Products that do not pass pre-review still need inspection.
