From Lianyungang to Baytown, cargo moves from northern Jiangsu through Lianyungang on the Yellow Sea, crosses a Panama Canal corridor whose draft limit depends on Gatun Lake, and is discharged at the port of Baytown.
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
Route profile
Jiangsu's Yellow Sea port, with a simplified document list for 'new three' cargo since 2024 and its own guide for energy-storage units on break-bulk ships.
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
They run from the Lianyungang terminal through the voyage to Baytown and the United States import file.
Under Lianyungang MSA's Notice No. 1 of 2024 the cargo side of a 'new three' filing needs four items: safe-carriage declaration, packing certificate signed by an inspector, packaging inspection certificate where the goods are packaged, and a power of attorney. A shorter list puts more weight on each paper, and the packing certificate still requires a certified inspector after supervised stuffing.
What Anxin does: We prepare the four cargo-side documents together and check that the packing certificate, the packaging certificate and the declaration describe the same UN numbers and quantities.
The Panama Canal Authority sets the maximum draft in the Neopanamax locks according to Gatun Lake levels. In September 2026 it postponed a planned cut from 14.63 m to 14.48 m that was due on 1 October (advisory A-33-2026). A lower limit means ships transiting the new locks can load less.
What Anxin does: We check the canal advisory in force when we quote for Baytown and ask carriers to confirm that the booked vessel's routing and any canal surcharge will not change before sailing.
DHS added lithium to the Uyghur Forced Labor Prevention Act high-priority sectors in August 2025. By then CBP had stopped more than 16,700 shipments for UFLPA examination. For battery importers the practical effect is that CBP can ask where cells, cathode and lithium compounds came from, and a shipment waits while the importer answers.
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.
Small cells and batteries shipped under IMDG special provision 188 do not need a dangerous goods declaration at sea, but 49 CFR 171.25(b)(3) adds a US condition: each package of UN3480 or UN3090 must carry the 'FORBIDDEN FOR TRANSPORT ABOARD PASSENGER AIRCRAFT' marking or a Cargo Aircraft Only label, and so must packages of batteries with or in equipment above 5 kg net. Cartons printed for other markets often lack it.
What Anxin does: When the shipper declares SP188 for a Baytown booking, we check the carton photos for the US marking or CAO label before stuffing, not after discharge.
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 Baytown includes products with button or coin cells, we ask for the certificate and photos of the battery compartment warnings before booking.

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

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 Lianyungang 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.
Risk & mitigation
| Risk | Where | Mitigation | Who acts |
|---|---|---|---|
| One of the four documents inconsistent with the others | Lianyungang MSA filing | Cross-check before submission | 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 |
| SP188 cartons without the US marking | Discharge and onward trucking | Marking or CAO label checked on carton photos before stuffing | Shipper, checked by Anxin |
Questions
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.
Under its Notice No. 1 of 2024, the cargo side submits the DG safe-carriage declaration, the inspector-signed packing certificate, the packaging inspection certificate where the goods are packaged, and a power of attorney.
