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.

Lithium batteries for Anchorage go from the Pearl River Delta via Nansha. On the way they face a North Pacific crossing with no chokepoint but real winter-storm exposure, and they arrive at the port of Anchorage.
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
- Nansha export
- Dongguan–Nansha one-box
- ISF filer
- Supply-chain tracing file
- HTS code 8507.60
Route profile
The Guangzhou → Anchorage route in brief
Transpacific (North Pacific)
A North Pacific crossing with no canal or chokepoint risk, but with a record of winter storms strong enough to collapse container stacks.
Where this route gets difficult
What to watch between Guangzhou and Anchorage: 6 points
Listed from loading in Guangzhou to import into United States, each with what we do about it.
- Origin port
Pearl River typhoon season and rolled boxes
The tropical cyclone season in the region runs from June to October according to the Hong Kong Observatory, with July to September the busiest months. At Nansha, on the Pearl River mouth, a gate closure or a vessel change sends the DG filings and the packing certificate after the box to its 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.
- Origin port
Packaging certificate data now shared in Dongguan
Dongguan Customs and Dongguan MSA began sharing dangerous-goods packaging certificate data in September 2026, which they called a first in China, and agreed joint action on concealed and false declarations; Huangpu Customs runs a joint 'lithium batteries going overseas' service against misdeclaration as well. A mismatch between packaging certificate and MSA filing is visible to both.
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.
- 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.
- 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 Anchorage, 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.
- Import country
'China' has to be marked on each article or its container
19 CFR 134.11 requires every imported article, or its container, to carry the English name of the country of origin in a conspicuous place, as legibly, indelibly and permanently as the article allows, at the time it is imported. Batteries and battery products reaching Anchorage without it can be held until they are marked.
What Anxin does: We check product and carton photos for a durable 'Made in China' marking before stuffing in Guangzhou, rather than leaving it for re-marking in a US warehouse.
- Import country
Button and coin cells: Reese's Law
Consumer products containing button or coin cells manufactured or imported after 19 March 2024 must meet the UL 4200A-2023 performance and warning-label rules adopted as 16 CFR part 1263, and battery packaging labels have been mandatory since 21 September 2024. The importer also needs a certificate citing the rule.
What Anxin does: When a shipment for Anchorage includes products with button or coin cells, we ask for the certificate and photos of the battery compartment warnings before booking.
Documents & compliance
Documents to line up for Guangzhou → Anchorage

- Container packing certificate signed by a certified packing inspector after supervised stuffing
- Transport-condition classification report where applicable

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 Anchorage.
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.
Risk & mitigation
Risk table for Guangzhou → Anchorage
| Risk | Where | Mitigation | Who acts |
|---|---|---|---|
| Mismatch between packaging certificate and MSA filing flagged by shared data | Dongguan / Nansha | Line-by-line check before submission | Anxin with the declarant |
| Typhoon closure after filings are made | Nansha, Jun–Oct | Slack in stuffing date; prompt refiling | Anxin with the declarant |
| Heavy-weather damage in a winter storm | North Pacific, Oct–Apr | CINS stuffing checks | Packing site, checked by Anxin |
| Truck stopped without a monitored emergency number | Road leg from the port | Emergency response provider confirmed before sailing | Importer, checked by Anxin |
Questions
Common questions on the Guangzhou → Anchorage 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.
