From Dalian to Georgetown (South Carolina), cargo moves through Dayaowan, crosses a corridor through the Panama Canal, and is discharged at the port of Georgetown (South Carolina).
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
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.
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
In the order the cargo meets them: at the loading port, at sea, at Georgetown (South Carolina) and at customs in United States.
The Bohai Sea and the northern Yellow Sea freeze every winter. For 2021/22 China's marine forecast centre expected floating ice around 15 nautical miles offshore in the northern Yellow Sea, where Dayaowan is, and around 60 in Liaodong Bay, with the peak between mid-January and mid-February.
What Anxin does: For January–February sailings from Dalian we allow extra time between stuffing and the DG cut-off and reconfirm the vessel schedule the week before loading.
The first half of the voyage crosses the North Pacific, where NOAA has recorded hurricane-force mid-latitude storms from October to April, most often in December.
What Anxin does: For October–April sailings we check blocking and bracing on stuffing photos before sealing.
Under 19 CFR 4.7 the carrier's cargo declaration must be in CBP's Automated Manifest System 24 hours before loading abroad. Without it, or with inaccurate data, the permit to unlade the container at Georgetown (South Carolina) can be delayed or refused.
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 Dalian, so the AMS filing and the DG manifest say the same thing.
19 CFR 134.11 requires every imported article, or its container, to carry the English name of the country of origin in a conspicuous place, as legibly, indelibly and permanently as the article allows, at the time it is imported. Batteries and battery products reaching Georgetown (South Carolina) without it can be held until they are marked.
What Anxin does: We check product and carton photos for a durable 'Made in China' marking before stuffing in Dalian, rather than leaving it for re-marking in a US warehouse.
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 Georgetown (South Carolina) includes products with button or coin cells, we ask for the certificate and photos of the battery compartment warnings before booking.

Documents & compliance
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.

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 |
|---|---|---|---|
| Ice delays berthing in mid-winter | Northern Yellow Sea, Jan–Feb | Extra time before cut-off; schedule reconfirmed | Carrier, monitored 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
For lithium-ion batteries classified in HTSUS 8507.60.0020 and entered from 1 January 2026, USTR set the Section 301 additional duty at 25%; EV traction batteries in 8507.60.0010 have been at 25% since 2024. Other duties can apply on top. The importer's customs broker confirms the classification and total duty; we make sure the invoice gives the broker enough detail to do so.
1 June to 30 November, peaking around 10 September, according to the US National Hurricane Center.
Sea ice forms every winter in the northern Yellow Sea; in 2021/22 it was forecast to reach about 15 nautical miles out there, peaking mid-January to mid-February. We plan extra time for those weeks.
