From Guangzhou to Prudhoe Bay, cargo moves from the Pearl River Delta via Nansha, crosses a North Pacific crossing with no chokepoint but real winter-storm exposure, and is discharged at the port of Prudhoe Bay.

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

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

Route profile

How Guangzhou → Prudhoe Bay differs from other lanes

Origin port

Guangzhou (Nansha)

Pearl River Delta battery cargo through Nansha, where a September 2026 agreement lets Dongguan-inspected containers load without a second MSA check, and where typhoon season runs June to October.

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 Prudhoe Bay: 6 points

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

  1. Origin port

    Customs and MSA now compare packaging certificates

    In September 2026 Dongguan Customs and Dongguan MSA started sharing dangerous-goods packaging certificate data, described as a first in China, together with joint action against concealed and false declarations; Huangpu Customs also runs a joint 'lithium batteries going overseas' service against misdeclaration. A packaging certificate that does not match the MSA filing is now visible to both agencies.

    What Anxin does: We check that the UN number, packaging code and quantities on the packaging certificate are exactly those on the MSA cargo report before either is submitted.

  2. 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.

  3. Sea corridor

    Winter storms with hurricane-force winds

    NOAA's Ocean Prediction Center found hurricane-force winds (64 knots and above) in North Pacific mid-latitude storms in every month from October to April, peaking in December, with 15 to 23 such storms per season in its 2001–2004 records. They are not typhoons, so they do not follow the tropical calendar.

    What Anxin does: For October–April sailings we check blocking and bracing on stuffing photos before sealing and confirm the full DG data are on the manifest.

  4. Import country

    The carrier's AMS manifest is due 24 hours before loading

    Besides the importer's ISF, CBP must receive the carrier's electronic cargo declaration through AMS 24 hours before the container is laden in Guangzhou (19 CFR 4.7). CBP does not issue the permit to unlade at Prudhoe Bay until it has that declaration, and late, incomplete or inaccurate cargo data can delay or deny it.

    What Anxin does: We give the carrier or NVOCC the final cargo description, HS code, UN number and package count before the documentation cut-off in Guangzhou, so the AMS filing and the DG manifest say the same thing.

  5. Import country

    Day 15 at the terminal: the General Order deadline

    US customs rules give an unentered container 15 calendar days at the place of unlading. After that the carrier hands it to a bonded general order warehouse, with transport and storage at the consignee's risk and expense, and for DG cargo that needs specialized storage the port director decides where it is kept (19 CFR 4.37).

    What Anxin does: We check with the importer's broker that the entry can be filed before arrival at Prudhoe Bay, and chase any missing invoice or HTS detail while the ship is still at sea.

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

Documents & compliance

What to have ready: Guangzhou to Prudhoe Bay

Test reports, safety data sheets and import certificates come from the shipper, factory and importer, not from Anxin; our part is to review them before booking.

At the Guangzhou end

  • Packaging certificate and MSA cargo report cross-checked line by line (UN number, packaging code, quantity)
  • 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
  • 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)

For the shipping line

  • Stuffing photos before, during and after packing, checked for blocking and bracing
  • Condition statement: new, used, damaged/defective (SP376) or for recycling (SP377)
  • SP188 cartons: US 'forbidden aboard passenger aircraft' marking or CAO label

For import into United States

  • Supply-chain tracing file for cells and lithium inputs, in case of a UFLPA request
  • CPSC certificate data and eFiling arrangement, if the product is subject to certification

Before you book

Match the details first

We line up UN numbers, model names and package counts across the Guangzhou 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 Prudhoe Bay.

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 Guangzhou → Prudhoe Bay route

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.

Weather is the main risk on this crossing: NOAA recorded hurricane-force North Pacific storms from October to April, most often in December. We tighten the packing checks for those sailings.

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.
