Lithium batteries for Trenton go out of Shanghai, where MSA spot-checks battery containers during and after filing. On the way they face a corridor into Atlantic Canada's waters, and they arrive at the port of Trenton.

The United States applies Section 301 and UFLPA scrutiny to Chinese lithium batteries and wants its manifest data before loading. The 5 points below are particular to this lane; each comes with what we do and the paperwork it touches.

What we need to start

  • Photo-verified packing certificate
  • Yangshan / Waigaoqiao export
  • Supply-chain tracing file
  • HTS code 8507.60
  • ISF filer

Route profile

How Shanghai → Trenton differs from other lanes

Origin port

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.

Sea corridor

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

What to watch between Shanghai and Trenton: 5 points

In the order the cargo meets them: at the loading port, at sea, at Trenton and at customs in United States.

  1. Origin port

    Photo evidence before Shanghai issues the packing certificate

    Shanghai's electronic packing certificate goes out by EDI only after the inspector has uploaded before, during and after stuffing photos through the MSA's remote system, with face recognition and phone location switched on. Missing, late or off-site photos, or photos that do not match the EDI cargo data, stop the container from loading. Stuffing sites outside Shanghai need registration with Shanghai MSA.

    What Anxin does: We confirm that the stuffing site (including factory sites in Jiangsu or Zhejiang) is registered for Shanghai's remote system, and we check the photo upload against the EDI data before the packing certificate is sent.

  2. Sea corridor

    Panama draft or Suez routing decides the first half

    Services to Trenton run either via Panama, where the Neopanamax draft depends on Gatun Lake (a planned cut was postponed in September 2026), or via Suez and the Mediterranean, where Mediterranean services used the Red Sea 57% of the time in September 2026.

    What Anxin does: We ask the carrier which routing the service uses and quote the options separately.

  3. Import country

    Section 301 at 25% on lithium-ion non-EV batteries from January 2026

    USTR's 2024 review moved lithium-ion batteries of HTSUS 8507.60.0020 (the 'other', non-passenger-EV line) from a 7.5% to a 25% additional duty for entries from 1 January 2026; EV traction batteries under 8507.60.0010 reached 25% in 2024. Other China-specific duties can stack on top and change with little notice, so the landed cost depends on the exact classification and entry date.

    What Anxin does: We do not give duty rulings. We make sure the invoice describes chemistry, configuration and application precisely enough for the importer's customs broker to classify it, and we flag the entry date when a vessel's arrival could straddle a duty change.

  4. 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.

  5. 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 Trenton. 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

Checklist for Shanghai → Trenton

Anxin reviews documents supplied by the shipper, manufacturer and importer; it does not issue test reports, safety data sheets or import certificates.

In Shanghai, before the box is loaded

  • Stuffing photos (before, during, after) uploaded to Shanghai MSA's remote system before the EDI packing certificate is sent
  • Stuffing site registered and geo-verified with Shanghai MSA; fire-safety proof for lithium DG warehouses
  • Transport-condition classification report where applicable
  • Load plan showing even weight distribution (no more than 60% of the cargo weight in either half of the container length)
  • 'Made in China' marking on articles or containers checked on photos

For the carrier and the voyage

  • In winter: ice capability of the vessel or feeder serving the port confirmed
  • 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)

For the importer in United States

  • HTSUS classification from the broker (8507.60.0010 vs .0020 decides the Section 301 line)
  • 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

Match the details first

We line up UN numbers, model names and package counts across the Shanghai filings, the booking with the carrier and the documents for United States before the booking is confirmed, so that a mismatch is fixed at origin rather than discovered at Trenton.

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

Questions about shipping from Shanghai to Trenton

Yes, if the container moves on a public highway. The IMDG waiver in 49 CFR 171.25(d)(2) only covers cargo that stays on the ship or moves between vessels; otherwise 49 CFR 172.604 requires a monitored number answered by someone with the emergency information. Goods shipped as 'Battery powered equipment' are exempt.

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.

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.
