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.

From Shenzhen to Valdez, cargo moves from Dongguan and Shenzhen factories via Yantian, crosses a North Pacific corridor with no canal or chokepoint, and is discharged at the port of Valdez.
The United States applies Section 301 and UFLPA scrutiny to Chinese lithium batteries and wants its manifest data before loading. The 5 points below are particular to this lane; each comes with what we do and the paperwork it touches.
What we need to start
- Typhoon season Jun–Oct
- Yantian / Shekou export
- Supply-chain tracing file
- HTS code 8507.60
- ISF filer
Route profile
The Shenzhen → Valdez route in brief
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
What to watch between Shenzhen and Valdez: 5 points
Listed from loading in Shenzhen to import into United States, each with what we do about it.
- Origin port
Typhoon season squeezes Shenzhen cut-offs
The Hong Kong Observatory puts the regional tropical cyclone season from June to October, busiest July to September. DG containers need their MSA filings approved and a signed packing certificate before loading, so a closed gate or a rolled vessel in typhoon weeks can push the whole document chain to a new sailing.
What Anxin does: From June to October we build slack into the stuffing date, confirm the DG cut-off with the carrier the week before loading, and resubmit filings promptly if the vessel changes.
- Sea corridor
No chokepoint, but North Pacific storms
The drawn corridor from Shenzhen crosses the North Pacific, with no canal and no Red Sea exposure. Weather is the risk instead. In November 2020 the ONE Apus, sailing from Yantian to Long Beach, suffered a stack collapse in a storm about 1,600 nautical miles north-west of Hawaii; its owners reported that more than 1,900 containers could be lost or damaged, including up to 40 hazmat boxes.
What Anxin does: For winter sailings especially, we review blocking and bracing on stuffing photos against the CINS points before sealing, and make sure the DG declaration is complete, so a damaged box can be identified and handled correctly.
- Import country
Section 301 at 25% on lithium-ion non-EV batteries from January 2026
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.
- Import country
ISF closes 24 hours before loading in Shenzhen
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 Shenzhen, ahead of the vessel's loading window.
- Import country
CPSC eFiling for certified consumer products
Consumer products that need a CPSC certificate have had their certificate data filed electronically at entry since 8 July 2026 (goods from a Foreign Trade Zone from 8 January 2027). A battery-powered product falls under it through the product's own rules, which the importer should settle before the goods reach Valdez.
What Anxin does: We ask whether the goods are consumer products that need a CPSC certificate and, if so, who files it, so that the question is settled before the goods arrive.
Documents & compliance
Documents to line up for Shenzhen → Valdez
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.
In Shenzhen, before the box is loaded
- Confirmation from the carrier of the DG cut-off at Yantian or Shekou, rechecked in typhoon weeks
- '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
Carrier and voyage
- Stuffing photos before, during and after packing, checked for blocking and bracing
- Dangerous goods declaration with UN number (3480 / 3481 / 3090 / 3091), proper shipping name and packing instruction (P903, or P908/P911 for damaged)
- Lithium battery mark (SP188 cargo) or class 9 labels and placards
For import into United States
- ISF filer named; stuffing location and consolidator sent right after packing
- CPSC certificate data and eFiling arrangement, if the product is subject to certification
- 24-hour emergency response number (and provider reference) for the US road leg
Before you book
Match the details first
We line up UN numbers, model names and package counts across the Shenzhen 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 Valdez.
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 table for Shenzhen → Valdez
| Risk | Where | Mitigation | Who acts |
|---|---|---|---|
| Typhoon closes terminals or delays the vessel after filings are made | Yantian / Shekou, Jun–Oct | Slack in stuffing date; refile quickly on vessel change | Anxin with the declarant |
| Stack collapse or cargo shift in a North Pacific storm | Mid-Pacific | Blocking and bracing checked before sealing; complete DG data for incident response | Packing site / carrier, checked by Anxin |
| 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
Common questions on the Shenzhen → Valdez route
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.
Since September 2026 Dongguan Customs and Dongguan MSA share dangerous-goods packaging certificate data and act jointly against false declarations, so the packaging certificate and the MSA filing should match exactly.
