Yellow Sea · East China Sea · North Pacific
Lithium batteries for Honolulu go out of Dalian, the north-east's gateway on the Yellow Sea. On the way they face the open North Pacific, where weather is the main risk, and they arrive at the port of Honolulu.
Honolulu 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
No canal or Red Sea passage, but a North Pacific crossing where winter storms have collapsed container stacks.
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
Loading port first, then the sea leg, then Honolulu 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.
According to Dayaowan MSA in April 2024, lithium battery cargo was often under-declared or misdeclared because the rules are complicated. It responded with a dedicated desk and hotline, priority for EV batteries, and AI-based document comparison intended to reduce container openings, which means any mismatch between the declaration and its supporting papers gets flagged.
What Anxin does: We reconcile the UN number, classification, packing group, quantity and SDS across every document before filing, which is exactly what an automated comparison will test.
NOAA's Ocean Prediction Center has recorded hurricane-force winds (64 knots or more) in mid-latitude North Pacific storms in every month from October to April, most often in December, with 15 to 23 such storms a season in its 2001–2004 study. These are not tropical systems, so they arrive outside typhoon season.
What Anxin does: For October–April sailings we check blocking and bracing on stuffing photos before sealing and confirm the full DG data are on the manifest.
Packages of UN3480 or UN3090 moving under IMDG special provision 188 skip the DG declaration at sea, yet 49 CFR 171.25(b)(3) still wants the 'FORBIDDEN FOR TRANSPORT ABOARD PASSENGER AIRCRAFT' mark or a Cargo Aircraft Only label on each one, and on packages of batteries with or in equipment over 5 kg net.
What Anxin does: When the shipper declares SP188 for a Honolulu booking, we check the carton photos for the US marking or CAO label before stuffing, not after discharge.
If a battery container waits at Honolulu, the demurrage or detention invoice has to arrive within 30 days and carry accurate and sufficient information, or the charge is not owed (46 CFR part 541). The billed party then has at least 30 days to dispute it; in 2025 the D.C. Circuit struck down only the rule on who may be invoiced.
What Anxin does: We keep the dates of discharge, availability and any DG hold for each container, so the importer can check invoices against them and dispute charges inside the FMC time limits.

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

A document that is present but inconsistent holds a booking as surely as a missing one: the UN number, model name or carton count reads differently in the Dalian export filings, the carrier booking and the United States import papers. We compare all three before confirming space.
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 |
| Declaration flagged by document comparison; container opened | Dayaowan | Cross-document reconciliation before filing | Anxin with the declarant |
| Heavy-weather damage in a winter storm | North Pacific, Oct–Apr | CINS stuffing checks | Packing site, checked 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 |
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.
Weather is the main risk on this crossing: NOAA recorded hurricane-force North Pacific storms from October to April, most often in December. We tighten the packing checks for those sailings.
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.
