From Lianyungang to Key West, cargo moves through Lianyungang port, crosses the Pacific, the Panama Canal and the Caribbean, and is discharged at the port of Key West.
The United States applies Section 301 and UFLPA scrutiny to Chinese lithium batteries and wants its manifest data before loading. The 6 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.
A Panama Canal corridor whose Neopanamax draft depends on Gatun Lake levels, followed by the Caribbean during hurricane season.


Where this route gets difficult
In the order the cargo meets them: at the loading port, at sea, at Key West and at customs in United States.
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.
Between April and July sea fog is a major marine hazard in the Yellow and Bohai Seas, the China Meteorological Administration says. Lianyungang, like Qingdao, can see vessels held at anchor by fog, and moving a box to another vessel means amending its DG filings.
What Anxin does: In fog season we keep slack between stuffing and the DG cut-off and have the filing data ready to amend.
The Atlantic hurricane season, covering the Caribbean and the Gulf of America, runs from 1 June to 30 November, peaking around 10 September, with an average of 14 named storms. Ports on the way to Key West close ahead of storms, and ships wait or divert.
What Anxin does: For August–October arrivals we build slack into delivery plans and pass the carrier's revised arrival straight to your consignee.
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.
US rules want a numeric emergency response telephone number on the shipping paper for battery cargo that leaves Key West by road, monitored for as long as the goods are in transport and answered by a person with the emergency information for UN3480 or UN3090. A call-back service fails the test (49 CFR 172.604); only the IMDG waiver for cargo that never touches a public highway avoids it.
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.
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 Key West booking, we check the carton photos for the US marking or CAO label before stuffing, not after discharge.

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

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 Lianyungang 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
| 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 |
| Hurricane closes ports or diverts the vessel | Caribbean / Gulf, Jun–Nov | Slack in delivery plan | Carrier / consignee |
| 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
No. The carrier must also send its cargo declaration through AMS 24 hours before loading, and CBP will not issue the permit to unlade without it.
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.
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.
