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 Panama Canal corridor whose draft limit depends on Gatun Lake; at the far end is the port of Boca Grande.
Boca Grande 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 6 route-specific points to plan for, what we do about each, and the documents to have ready before booking.
What we need to start
- Winter ice & spring fog
- Dalian Dayaowan export
- ISF filer
- Supply-chain tracing file
- HTS code 8507.60
Route profile
What sets Dalian → Boca Grande apart
United States
Two filings before loading, a Section 301 line set by classification, UFLPA supply-chain questions and a 15-day General Order clock after discharge.
Where this route gets difficult
6 points to plan for on the Dalian → Boca Grande route
In the order the cargo meets them: at the loading port, at sea, at Boca Grande and at customs in United States.
- Origin port
Fewer battery sailings from Dalian under JT/T 1543
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.
- Origin port
Winter sea ice near Dayaowan
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.
- Sea corridor
North Pacific winter storms before the canal
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.
- Import country
A monitored US emergency number for the truck leg
The IMDG waiver in 49 CFR 171.25(d)(2) spares the emergency telephone number only when cargo stays on the ship or moves between vessels without using a public highway. Once the container is trucked out of Boca Grande, the shipping paper needs a numeric emergency response number that is monitored at all times and answered by someone who knows the material; an answering service that calls back does not count. Goods shipped as 'Battery powered equipment' are exempt.
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.
- Import country
SP188 packages need an extra US marking
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 Boca Grande booking, we check the carton photos for the US marking or CAO label before stuffing, not after discharge.
- Import country
Unentered battery containers go to General Order after 15 days
A container landed at Boca Grande without a release permit may stay at the terminal only until the 15th calendar day. The carrier must then notify CBP and a bonded general order warehouse, which moves and stores the goods at the consignee's risk and expense (19 CFR 4.37). Not every general order warehouse can take Class 9 battery cargo, and where specialized storage is missing the port director decides where it goes.
What Anxin does: We check with the importer's broker that the entry can be filed before arrival at Boca Grande, and chase any missing invoice or HTS detail while the ship is still at sea.
Documents & compliance
What to have ready: Dalian to Boca Grande
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.
At the Dalian end
- JT/T 1543 conformity evidence from the manufacturer
- 'Made in China' marking on articles or containers checked on photos
- Safety data sheet and dangerous goods safe-carriage declaration for the MSA cargo report
- Customs packaging use-appraisal result for the dangerous goods packaging (with the maker's performance appraisal)
- Container packing certificate signed by a certified packing inspector after supervised stuffing
For the carrier and the voyage
- Canal routing and any canal-related surcharge confirmed for the booked vessel
- SP188 cartons: US 'forbidden aboard passenger aircraft' marking or CAO label
- UN 38.3 test summary for every cell and battery type
For the importer in United States
- 24-hour emergency response number (and provider reference) for the US road leg
- ISF filer named; stuffing location and consolidator sent right after packing
- HTSUS classification from the broker (8507.60.0010 vs .0020 decides the Section 301 line)
Before you book
Match the details first
We line up UN numbers, model names and package counts across the Dalian filings, the booking with the carrier and the documents for United States before the booking is confirmed, so that a mismatch is fixed at origin rather than discovered at Boca Grande.
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
Risks on this route and who deals with them
| 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 |
| SP188 cartons without the US marking | Discharge and onward trucking | Marking or CAO label checked on carton photos before stuffing | Shipper, checked by Anxin |
| Truck stopped without a monitored emergency number | Road leg from the port | Emergency response provider confirmed before sailing | Importer, checked by Anxin |
Questions
Questions about shipping from Dalian to Boca Grande
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.
