Dalian (Dayaowan)
North-east China's battery gateway at Dayaowan, with a small but growing lithium export flow, a local MSA that has named misdeclaration as its main problem, and both winter ice and spring fog.

This route runs through Dayaowan, where Liaoning's first JT/T 1543 lithium export sailed in May 2025, then follows a Pacific crossing and a Panama Canal transit; at the far end is the port of Brunswick.
The United States applies Section 301 and UFLPA scrutiny to Chinese lithium batteries and wants its manifest data before loading. Below are 5 route-specific points to plan for, what we do about each, and the documents to have ready before booking.
What we need to start
Route profile
North-east China's battery gateway at Dayaowan, with a small but growing lithium export flow, a local MSA that has named misdeclaration as its main problem, and both winter ice and spring fog.
A Pacific crossing, a Panama Canal transit that depends on lake levels, and a Caribbean passage in hurricane season.


Where this route gets difficult
In the order the cargo meets them: at the loading port, at sea, at Brunswick and at customs in United States.
Dalian's battery flow is modest: Dalian MSA recorded 885 TEU of lithium battery exports in the first four months of 2025, and Liaoning's first export under JT/T 1543 left Dayaowan on 4 May 2025. Carriers should refuse batteries that fail JT/T 1543, and a thin flow leaves fewer alternative sailings when a booking is turned down.
What Anxin does: We check JT/T 1543 conformity evidence with the manufacturer before booking and confirm the carrier's acceptance of the UN numbers in writing.
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.
USTR's 2024 review moved lithium-ion batteries of HTSUS 8507.60.0020 (the 'other', non-passenger-EV line) from a 7.5% to a 25% additional duty for entries from 1 January 2026; EV traction batteries under 8507.60.0010 reached 25% in 2024. Other China-specific duties can stack on top and change with little notice, so the landed cost depends on the exact classification and entry date.
What Anxin does: We do not give duty rulings. We make sure the invoice describes chemistry, configuration and application precisely enough for the importer's customs broker to classify it, and we flag the entry date when a vessel's arrival could straddle a duty change.
US rules want a numeric emergency response telephone number on the shipping paper for battery cargo that leaves Brunswick 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.
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 Brunswick.
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.

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 Dalian 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 |
|---|---|---|---|
| Truck stopped without a monitored emergency number | Road leg from the port | Emergency response provider confirmed before sailing | Importer, 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.
Dayaowan MSA reported in 2024 that omissions and misdeclarations of lithium battery cargo were frequent because the rules are complex, and it uses AI document comparison. Consistent data across the declaration, SDS and packing documents is the main defence.
