This route runs out of Shanghai, where MSA spot-checks battery containers during and after filing, then follows a long voyage ending in the North Atlantic or the Gulf of St Lawrence; at the far end is the port of Detroit.

The United States applies Section 301 and UFLPA scrutiny to Chinese lithium batteries and wants its manifest data before loading. The 6 points below are particular to this lane; each comes with what we do and the paperwork it touches.

What we need to start

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

Route profile

What sets Shanghai → Detroit apart

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

6 points to plan for on the Shanghai → Detroit route

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

  1. 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.

  2. 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.

  3. Sea corridor

    Panama or Suez: the routing question for Detroit

    The first half of a voyage to Detroit goes either through Panama, where Gatun Lake sets the Neopanamax draft (a planned cut was postponed in September 2026), or through 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.

  4. Import country

    ISF closes 24 hours before loading in Shanghai

    The Importer Security Filing must reach CBP no later than 24 hours before the container is laden aboard the vessel abroad. CBP's liquidated damages guidelines provide for a claim per violation for late, inaccurate or incomplete filings. Two of the data elements, the container stuffing location and the consolidator, only exist once the box is packed.

    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.

  5. Import country

    A US-only carton mark for SP188 shipments

    Packages of UN3480 or UN3090 moving under IMDG special provision 188 skip the DG declaration at sea, yet 49 CFR 171.25(b)(3) still wants the 'FORBIDDEN FOR TRANSPORT ABOARD PASSENGER AIRCRAFT' mark or a Cargo Aircraft Only label on each one, and on packages of batteries with or in equipment over 5 kg net.

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

  6. Import country

    The FMC's 30-day rules on demurrage and detention bills

    If a battery container waits at Detroit, the demurrage or detention invoice has to arrive within 30 days and carry accurate and sufficient information, or the charge is not owed (46 CFR part 541). The billed party then has at least 30 days to dispute it; in 2025 the D.C. Circuit struck down only the rule on who may be invoiced.

    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

What to have ready: Shanghai to Detroit

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

At the Shanghai end

  • Stuffing site registered and geo-verified with Shanghai MSA; fire-safety proof for lithium DG warehouses
  • 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

For the shipping line

  • 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

  • ISF filer named; stuffing location and consolidator sent right after packing
  • 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

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 Shanghai 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

Shanghai → Detroit: questions we are asked

No. The carrier must also send its cargo declaration through AMS 24 hours before loading, and CBP will not issue the permit to unlade without it.

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.

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.
