Lithium batteries for Oakland go out of Nansha, at the mouth of the Pearl River. On the way they face a North Pacific corridor with no canal or chokepoint, and they arrive at the port of Oakland.

Oakland means US customs filings that are due while the container is still in Guangzhou, and a supply chain CBP may ask to see. 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
  • Supply-chain tracing file
  • HTS code 8507.60
  • ISF filer

Route profile

The Guangzhou → Oakland 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

From ISF and AMS in China to a monitored emergency number on the US truck leg, with Section 301 and UFLPA shaping what arrives.

Where this route gets difficult

5 points to plan for on the Guangzhou → Oakland route

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

  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

    Hurricane-force winter storms, October to April

    NOAA's Ocean Prediction Center has recorded hurricane-force winds (64 knots or more) in mid-latitude North Pacific storms in every month from October to April, most often in December, with 15 to 23 such storms a season in its 2001–2004 study. These are not tropical systems, so they arrive outside typhoon season.

    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.

  3. Import country

    California's battery-embedded product rules since January 2026

    Under California SB 1215, consumers have paid a recycling fee on covered battery-embedded products since 1 January 2026, and those products must be labelled with the maker's name or brand and the battery chemistry, or give that information on the maker's website. Manufacturers must also list covered and exempt products in an annual notice to retailers and CalRecycle.

    What Anxin does: If the goods landing at Oakland are devices with built-in batteries for sale in California, we ask the brand owner to confirm the chemistry labelling and the CalRecycle notice before shipping.

  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 Oakland 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

    CPSC eFiling for certified consumer products

    Consumer products that need a CPSC certificate have had their certificate data filed electronically at entry since 8 July 2026 (goods from a Foreign Trade Zone from 8 January 2027). A battery-powered product falls under it through the product's own rules, which the importer should settle before the goods reach Oakland.

    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 Guangzhou → Oakland

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.

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 carrier and the voyage

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

  • 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
  • Importer of record and the licensed customs broker who will file the entry

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 Oakland

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.
