This route runs through Lianyungang port, then follows a long voyage ending in the North Atlantic or the Gulf of St Lawrence; at the far end is the port of Cleveland.
US entry is decided as much by paperwork filed in China as by anything at the port. 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
Route profile
A final leg through North Atlantic or St Lawrence waters, with ice from December to May and winter storms that peak in January.
Section 301 duty on Chinese lithium-ion batteries at 25% since January 2026, UFLPA scrutiny of lithium supply chains, ISF 24 hours before loading, and a US-only marking rule for SP188 packages.


Where this route gets difficult
Listed from loading in Lianyungang to import into United States, each with what we do about it.
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 first half of a voyage to Cleveland goes either through Panama, where Gatun Lake sets the Neopanamax draft (a planned cut was postponed in September 2026), or through Suez and the Mediterranean, where Mediterranean services used the Red Sea 57% of the time in September 2026.
What Anxin does: We ask the carrier which routing the service uses and quote the options separately.
Besides the importer's ISF, CBP must receive the carrier's electronic cargo declaration through AMS 24 hours before the container is laden in Lianyungang (19 CFR 4.7). CBP does not issue the permit to unlade at Cleveland 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 Lianyungang, so the AMS filing and the DG manifest say the same thing.
The Importer Security Filing must reach CBP no later than 24 hours before the container is laden aboard the vessel abroad. CBP's liquidated damages guidelines provide for a claim per violation for late, inaccurate or incomplete filings. Two of the data elements, the container stuffing location and the consolidator, only exist once the box is packed.
What Anxin does: We send the importer's ISF filer the stuffing location, consolidator and manufacturer details as soon as the container is packed in Lianyungang, ahead of the vessel's loading window.
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 Cleveland booking, we check the carton photos for the US marking or CAO label before stuffing, not after discharge.

Documents & compliance
These documents come from the shipper, the manufacturer and the importer. Anxin checks them against each other; 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 |
| Late or inaccurate ISF | Before loading abroad | Stuffing and consolidator data sent to the ISF filer immediately after packing | Anxin with the ISF filer |
| SP188 cartons without the US marking | Discharge and onward trucking | Marking or CAO label checked on carton photos before stuffing | Shipper, checked by 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
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.
Yes, but the Coast Guard's icebreaking season on the Gulf of St Lawrence and the river typically runs from December to May, and vessels must report their ice class to ECAREG CANADA. We confirm the vessel's ice capability when booking.
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.
