From Guangzhou to Longview, cargo moves from the Pearl River Delta via Nansha, crosses a North Pacific corridor with no canal or chokepoint, and is discharged at the port of Longview.

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

  • Nansha export
  • Dongguan–Nansha one-box
  • Supply-chain tracing file
  • HTS code 8507.60

Route profile

The Guangzhou → Longview route in brief

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

5 pain points from Guangzhou to Longview

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

  1. Origin port

    A recommended 25% charge for ESS from Nansha

    Nansha MSA told a July 2024 meeting on energy-storage carriage that ESS batteries should travel at roughly 25% state of charge, with accidental activation prevented. It is advice, not a binding rule, yet it is the number the local authority has put on the record.

    What Anxin does: For ESS cargo leaving Nansha we ask the manufacturer to state the shipping state of charge and the anti-activation measures in writing, and put both in the documents the carrier sees.

  2. Sea corridor

    No chokepoint, but North Pacific storms

    The drawn corridor from Guangzhou crosses the North Pacific, with no canal and no Red Sea exposure. Weather is the risk instead. In November 2020 the ONE Apus, sailing from Yantian to Long Beach, suffered a stack collapse in a storm about 1,600 nautical miles north-west of Hawaii; its owners reported that more than 1,900 containers could be lost or damaged, including up to 40 hazmat boxes.

    What Anxin does: For winter sailings especially, we review blocking and bracing on stuffing photos against the CINS points before sealing, and make sure the DG declaration is complete, so a damaged box can be identified and handled correctly.

  3. Import country

    The ISF deadline falls before the box is loaded

    CBP must have the Importer Security Filing 24 hours before the container is laden in Guangzhou, and its liquidated damages guidelines provide for a claim for each late, inaccurate or incomplete filing. The stuffing location and consolidator can only be filled in once the container is packed, which leaves a short window.

    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 Guangzhou, ahead of the vessel's loading window.

  4. Import country

    AMS: the manifest CBP sees before the ship leaves Guangzhou

    Under 19 CFR 4.7 the carrier's cargo declaration must be in CBP's Automated Manifest System 24 hours before loading abroad. Without it, or with inaccurate data, the permit to unlade the container at Longview can be delayed or refused.

    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

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

    If a battery container waits at Longview, 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: Guangzhou to Longview

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

Before loading in Guangzhou

  • For ESS: written shipping state of charge and anti-activation measures from the manufacturer
  • 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
  • Transport-condition classification report where applicable

For the carrier and the voyage

  • Stuffing photos before, during and after packing, checked for blocking and bracing
  • 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 import into United States

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

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 → Longview 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.

Nansha MSA has recommended around 25% for ESS batteries and measures against accidental activation. Treat it as the local authority's recommendation; the carrier's own acceptance conditions also apply.
