Asia – Americas via the Panama Canal
A Pacific crossing, a Panama Canal transit that depends on lake levels, and a Caribbean passage in hurricane season.
North America · sea freight from Dalian
Dalian to Baltimore
Yellow Sea · Korea Strait · Tsugaru Strait · Eastern Pacific · Panama Canal · Caribbean Sea · Windward Passage · US East Coast
This route runs out of Dalian, the north-east's gateway on the Yellow Sea, then follows the Pacific, the Panama Canal and the Caribbean; at the far end is the port of Baltimore.
Baltimore means US customs filings that are due while the container is still in Dalian, and a supply chain CBP may ask to see. 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
A Pacific crossing, a Panama Canal transit that depends on lake levels, and a Caribbean passage in hurricane season.
A duty line set by the exact 8507.60 code, lithium supply-chain questions under UFLPA, and ISF and AMS filings that are due before the box is loaded.


Where this route gets difficult
Loading port first, then the sea leg, then Baltimore and the United States market.
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.
How deep ships can load through Panama's new locks depends on Gatun Lake. In September 2026 the Canal Authority's advisory A-33-2026 postponed a cut in the Neopanamax draft from 14.63 m to 14.48 m that had been due on 1 October, citing lake levels; a lower limit reduces what a ship bound for Baltimore can carry.
What Anxin does: We check the canal advisory in force when we quote for Baltimore and ask carriers to confirm that the booked vessel's routing and any canal surcharge will not change before sailing.
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.
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.
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 Dalian, ahead of the vessel's loading window.

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 |
| 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 |
| Late or inaccurate ISF | Before loading abroad | Stuffing and consolidator data sent to the ISF filer immediately after packing | Anxin with the ISF filer |
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.
