This route runs from the Pearl River Delta via Nansha, then follows a long voyage ending in the North Atlantic or the Gulf of St Lawrence; at the far end is the port of Milwaukee.

US entry is decided as much by paperwork filed in China as by anything at the port. This page sets out 5 points specific to this route, how Anxin handles each one and which documents to prepare.

What we need to start

  • Dongguan–Nansha one-box
  • Typhoon season Jun–Oct
  • HTS code 8507.60
  • ISF filer
  • Supply-chain tracing file

Route profile

How Guangzhou → Milwaukee differs from other lanes

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.

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

What to watch between Guangzhou and Milwaukee: 5 points

Listed from loading in Guangzhou to import into United States, each with what we do about it.

  1. Origin port

    Typhoon weeks at the Pearl River mouth

    The Hong Kong Observatory puts the region's tropical cyclone season from June to October, busiest July to September. Nansha sits at the mouth of the Pearl River; a closed gate or a changed vessel means the DG filings and the packing certificate have to follow the box to a new sailing.

    What Anxin does: From June to October we leave slack between stuffing and the DG cut-off at Nansha and refile quickly if the vessel changes.

  2. Sea corridor

    Panama draft or Suez routing decides the first half

    Services to Milwaukee 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

    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 Milwaukee.

    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

    Where the lithium came from: UFLPA questions at entry

    Since August 2025 lithium has been a high-priority sector under the Uyghur Forced Labor Prevention Act, and CBP had by then stopped more than 16,700 shipments for UFLPA review. A container for Milwaukee can be held while the importer shows where the cells, cathode material and lithium compounds were sourced.

    What Anxin does: We tell the importer at quotation stage that supply-chain tracing may be requested, and keep manufacturer names and addresses consistent across invoice, packing list and ISF so the paper trail does not contradict itself.

  5. Import country

    A monitored US emergency number for the truck leg

    The IMDG waiver in 49 CFR 171.25(d)(2) spares the emergency telephone number only when cargo stays on the ship or moves between vessels without using a public highway. Once the container is trucked out of Milwaukee, the shipping paper needs a numeric emergency response number that is monitored at all times and answered by someone who knows the material; an answering service that calls back does not count. Goods shipped as 'Battery powered equipment' are exempt.

    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.

Documents & compliance

Documents to line up for Guangzhou → Milwaukee

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.

In Guangzhou, before the box is loaded

  • 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
  • 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
  • Dangerous goods declaration with UN number (3480 / 3481 / 3090 / 3091), proper shipping name and packing instruction (P903, or P908/P911 for damaged)
  • Lithium battery mark (SP188 cargo) or class 9 labels and placards

For the importer in United States

  • HTSUS classification from the broker (8507.60.0010 vs .0020 decides the Section 301 line)
  • ISF filer named; stuffing location and consolidator sent right after packing
  • CPSC certificate data and eFiling arrangement, if the product is subject to certification

Before you book

One consistent file

A document that is present but inconsistent holds a booking as surely as a missing one: the UN number, model name or carton count reads differently in the Guangzhou export filings, the carrier booking and the United States import papers. We compare all three before confirming space.

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 Guangzhou to Milwaukee

Yes. Under 49 CFR 171.25(b)(3), SP188 packages of UN3480 or UN3090 need the 'FORBIDDEN FOR TRANSPORT ABOARD PASSENGER AIRCRAFT' marking or a Cargo Aircraft Only label, and so do packages of batteries packed with or contained in equipment above 5 kg net. We check for it on carton photos before stuffing.

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.

Both now have a one-box arrangement with Dongguan MSA: Yantian since May 2026 and Nansha since 22 September 2026, so a container inspected at the factory need not be reopened at the terminal unless necessary. The choice then comes down to the carrier's service to your destination and the cut-offs; we compare both when you book.
