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 Savannah go through Guangzhou's Nansha terminals, which since September 2026 accept Dongguan-inspected battery boxes without a second check. On the way they face a Pacific crossing and a Panama Canal transit, and they arrive at the port of Savannah.
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. 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
- ISF filer
Route profile
How Guangzhou → Savannah differs from other lanes
United States
US entry hinges on filings made in China (ISF and AMS), a traceable lithium supply chain and a road leg that is regulated as a hazmat move.
Where this route gets difficult
What to watch between Guangzhou and Savannah: 5 points
Loading port first, then the sea leg, then Savannah and the United States market.
- Origin port
Dongguan factory to Nansha: the new one-box route
On 22 September 2026 Dongguan and Guangzhou MSA agreed to extend the one-box model to Nansha: Guangzhou MSA recognises Dongguan MSA's factory inspection and does not re-inspect unless necessary. The first box was stuffed in Dongguan that day and sailed from Nansha to Singapore on 24 September. The model is new at Nansha, so the factory record has to be right first time.
What Anxin does: We ask at booking whether your Dongguan factory can use the Nansha one-box arrangement and make sure the stuffing photos, packing certificate and DG declaration match, because a mismatch is the 'necessary' case that brings the second inspection back.
- Origin port
Nansha MSA's state-of-charge advice for energy storage
At a July 2024 meeting on energy-storage carriage, Nansha MSA recommended shipping ESS batteries at a state of charge of around 25% and preventing accidental activation. It is a recommendation rather than a fixed rule, but it is the figure the local authority has put on 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.
- Sea corridor
North Pacific winter storms before the canal
NOAA's Ocean Prediction Center has recorded hurricane-force North Pacific storms in every month from October to April, most often in December. The Pacific leg to Panama crosses that ocean.
What Anxin does: For October–April sailings we check blocking and bracing on stuffing photos before sealing.

Georgia Ports: no terminal storage for UN3536 battery systems
Georgia Ports Authority rules effective 1 October 2025 treat battery energy storage systems (UN3536) like explosives: at least 96 hours' written notice, no storage on any Authority facility, no receipt by rail, and at Garden City discharge or loading directly shipside. Packed cells and modules under UN3480 are not caught, so the UN number decides how the container is handled at Savannah.
What Anxin does: We confirm the UN number with the shipper before booking. For a containerised energy storage system, we make sure the carrier gives the 96-hour notice and the consignee has trucks ready at the ship.
- 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 Savannah 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.
Documents & compliance
Documents to line up for Guangzhou → Savannah
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
- For ESS: written shipping state of charge and anti-activation measures from the manufacturer
- 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)
- '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
For the carrier and the voyage
- Canal routing and any canal-related surcharge confirmed for the booked vessel
- Condition statement: new, used, damaged/defective (SP376) or for recycling (SP377)
- SP188 cartons: US 'forbidden aboard passenger aircraft' marking or CAO label
For the importer in United States
- Importer of record and the licensed customs broker who will file the entry
- ISF filer named; stuffing location and consolidator sent right after packing
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 Savannah.
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
Risks on this route and who deals with them
| Risk | Where | Mitigation | Who acts |
|---|---|---|---|
| Second inspection at Nansha because factory records are incomplete | Dongguan factory → Nansha | Photos, packing certificate and declaration matched before trucking | Anxin |
| Permit to unlade delayed for a late or inaccurate AMS manifest | Port of discharge | Final cargo data given to the carrier before the cut-off | Carrier / NVOCC, with data from Anxin |
Questions
Questions about shipping from Guangzhou to Savannah
Yes, if the container moves on a public highway. The IMDG waiver in 49 CFR 171.25(d)(2) only covers cargo that stays on the ship or moves between vessels; otherwise 49 CFR 172.604 requires a monitored number answered by someone with the emergency information. Goods shipped as 'Battery powered equipment' are exempt.
It can. In September 2026 the Panama Canal Authority postponed a planned draft cut in the Neopanamax locks because of Gatun Lake levels (advisory A-33-2026). We check the advisory in force when quoting.
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.
