This route runs out of Shanghai, where MSA spot-checks battery containers during and after filing, then follows a corridor into Atlantic Canada's waters; at the far end is the port of Duluth.

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 6 route-specific points to plan for, what we do about each, and the documents to have ready before booking.

What we need to start

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

Route profile

What sets Shanghai → Duluth 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.

Import country

United States

Section 301 duty on Chinese lithium-ion batteries at 25% since January 2026, UFLPA scrutiny of lithium supply chains, ISF 24 hours before loading, and a US-only marking rule for SP188 packages.

Where this route gets difficult

Where Shanghai → Duluth shipments get held up: 6 points

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

  1. 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.

  2. 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.

  3. Sea corridor

    North Atlantic winter storms peak in January

    NOAA's Ocean Prediction Center has recorded hurricane-force mid-latitude storms in the North Atlantic from October to April, most often in January. The final leg to Duluth crosses those waters.

    What Anxin does: For winter sailings we check blocking and bracing on stuffing photos before sealing.

  4. Import country

    Which 8507.60 line decides the Section 301 duty

    For lithium-ion batteries entered from 1 January 2026 USTR set the Section 301 additional duty on HTSUS 8507.60.0020 (the non-EV line) at 25%, the level EV batteries under 8507.60.0010 reached in 2024. Other China-specific duties can be added and change at short notice, so the classification and the entry date both move the landed cost at Duluth.

    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.

  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 Duluth booking, we check the carton photos for the US marking or CAO label before stuffing, not after discharge.

  6. 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.

Documents & compliance

Documents to line up for Shanghai → Duluth

These documents come from the shipper, the manufacturer and the importer. Anxin checks them against each other; it does not issue test reports, safety data sheets or import certificates.

At the Shanghai end

  • 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
  • Per-container evidence file (UN38.3 summary, SDS, photos, short-circuit protection) kept for Shanghai MSA spot checks
  • 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

Carrier and 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)
  • Importer of record and the licensed customs broker who will file the entry
  • ISF filer named; stuffing location and consolidator sent right after packing

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 Duluth.

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 Duluth

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.

Yes, but the Coast Guard's icebreaking season on the Gulf of St Lawrence and the river typically runs from December to May, and vessels must report their ice class to ECAREG CANADA. We confirm the vessel's ice capability when booking.

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.
