Transpacific (North Pacific)
A North Pacific crossing with no canal or chokepoint risk, but with a record of winter storms strong enough to collapse container stacks.
North America · sea freight from Qingdao
Qingdao to Ketchikan
Yellow Sea · Korea Strait · Sea of Japan · Tsugaru Strait · Gulf of Alaska
This route runs out of Qingdao on the Yellow Sea, where April to July is fog season, then follows a great-circle crossing of the North Pacific; at the far end is the port of Ketchikan.
US entry is decided as much by paperwork filed in China as by anything at the port. This page sets out 6 points specific to this route, how Anxin handles each one and which documents to prepare.
What we need to start
Route profile
A North Pacific crossing with no canal or chokepoint risk, but with a record of winter storms strong enough to collapse container stacks.
Section 301 duty on Chinese lithium-ion batteries at 25% since January 2026, UFLPA scrutiny of lithium supply chains, ISF 24 hours before loading, and a US-only marking rule for SP188 packages.


Where this route gets difficult
In the order the cargo meets them: at the loading port, at sea, at Ketchikan and at customs in United States.
The China Meteorological Administration lists sea fog among the major marine hazards of the Yellow and Bohai Seas, mostly between April and July and with a serious effect on shipping. At Qingdao a fog hold can shift a battery container onto another vessel, and its DG filings must follow.
What Anxin does: In fog season we leave slack between stuffing and the DG cut-off at Qianwan and keep the cargo report ready to amend quickly if the vessel changes.
Qingdao MSA's 'one-document, one-box' pilot has since November 2024 covered water-to-water transhipment of lithium batteries and other 'new three' cargo between Dagang and Qianwan, with one outbound cargo report and no more than one packing inspection within the pilot ports. In the launch case, three cargo and three ship reports became one cargo and two ship reports.
What Anxin does: If your cargo is stuffed at a Dagang yard or reaches Qianwan by water, we check at booking whether it qualifies for the pilot and file once, so the box is not reopened between terminals.
NOAA's Ocean Prediction Center found hurricane-force winds (64 knots and above) in North Pacific mid-latitude storms in every month from October to April, peaking in December, with 15 to 23 such storms per season in its 2001–2004 records. They are not typhoons, so they do not follow the tropical calendar.
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 Ketchikan booking, we check the carton photos for the US marking or CAO label before stuffing, not after discharge.
A container landed at Ketchikan 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 Ketchikan, and chase any missing invoice or HTS detail while the ship is still at sea.
If a battery container waits at Ketchikan, 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 Qingdao 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 |
|---|---|---|---|
| Fog hold forces a vessel change after filing | Qingdao, Apr–Jul | Slack in schedule; amendment-ready filing | Anxin with the declarant |
| Duplicate filing or reopening between Qingdao terminals | Dagang → Qianwan | Pilot eligibility checked at booking; single cargo report | 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
Yes, if the container moves on a public highway. The IMDG waiver in 49 CFR 171.25(d)(2) only covers cargo that stays on the ship or moves between vessels; otherwise 49 CFR 172.604 requires a monitored number answered by someone with the emergency information. Goods shipped as 'Battery powered equipment' are exempt.
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.
Mainly April to July, according to the China Meteorological Administration, which calls sea fog a major hazard for Yellow Sea transport.

We check carrier acceptance for Qingdao → Ketchikan before any booking, and ask for missing battery documents first.
