This route runs out of Nansha, at the mouth of the Pearl River, then follows a corridor through the Panama Canal; at the far end is the port of Gulfport.
US entry is decided as much by paperwork filed in China as by anything at the port. 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
What sets Guangzhou → Gulfport apart
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 Gulfport: 5 points
In the order the cargo meets them: at the loading port, at sea, at Gulfport and at customs in United States.
- 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.
- Sea corridor
Gatun Lake sets the Neopanamax draft
How deep ships can load through Panama's new locks depends on Gatun Lake. In September 2026 the Canal Authority's advisory A-33-2026 postponed a cut in the Neopanamax draft from 14.63 m to 14.48 m that had been due on 1 October, citing lake levels; a lower limit reduces what a ship bound for Gulfport can carry.
What Anxin does: We check the canal advisory in force when we quote for Gulfport and ask carriers to confirm that the booked vessel's routing and any canal surcharge will not change before sailing.
- Import country
Unentered battery containers go to General Order after 15 days
A container landed at Gulfport without a release permit may stay at the terminal only until the 15th calendar day. The carrier must then notify CBP and a bonded general order warehouse, which moves and stores the goods at the consignee's risk and expense (19 CFR 4.37). Not every general order warehouse can take Class 9 battery cargo, and where specialized storage is missing the port director decides where it goes.
What Anxin does: We check with the importer's broker that the entry can be filed before arrival at Gulfport, and chase any missing invoice or HTS detail while the ship is still at sea.
- Import country
Where the lithium came from: UFLPA questions at entry
Since August 2025 lithium has been a high-priority sector under the Uyghur Forced Labor Prevention Act, and CBP had by then stopped more than 16,700 shipments for UFLPA review. A container for Gulfport can be held while the importer shows where the cells, cathode material and lithium compounds were sourced.
What Anxin does: We tell the importer at quotation stage that supply-chain tracing may be requested, and keep manufacturer names and addresses consistent across invoice, packing list and ISF so the paper trail does not contradict itself.
- 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 Gulfport includes products with button or coin cells, we ask for the certificate and photos of the battery compartment warnings before booking.
Documents & compliance
What to have ready: Guangzhou to Gulfport
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
- 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
- Load plan showing even weight distribution (no more than 60% of the cargo weight in either half of the container length)
For the carrier and the voyage
- Canal routing and any canal-related surcharge confirmed for the booked vessel
- SP188 cartons: US 'forbidden aboard passenger aircraft' marking or CAO label
- UN 38.3 test summary for every cell and battery type
For import into United States
- Supply-chain tracing file for cells and lithium inputs, in case of a UFLPA request
- 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
Send the file once, complete
Most delays on this route start with a document that exists but does not match: a UN number, a model name or a package count that differs between the Guangzhou filings, the carrier booking and the United States import file. We check the three against each other before the booking is confirmed.
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
What could go wrong from Guangzhou to Gulfport, and who acts
| Risk | Where | Mitigation | Who acts |
|---|---|---|---|
| Typhoon closure after filings are made | Nansha, Jun–Oct | Slack in stuffing date; prompt refiling | Anxin with the declarant |
| Draft cut reduces capacity or adds surcharges | Panama Canal | Advisory checked at quotation; carrier confirmation | Carrier, checked by Anxin |
| UFLPA detention pending supply-chain evidence | CBP at entry | Importer prepares tracing documents before shipping; consistent manufacturer data on all documents | Importer |
Questions
Questions about shipping from Guangzhou to Gulfport
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.
1 June to 30 November, peaking around 10 September, according to the US National Hurricane Center.
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.
