Shenzhen (Yantian / Shekou)
Pearl River Delta battery cargo, often stuffed at factories in Dongguan or Huizhou, exported through Yantian or Shekou, with a typhoon season from June to October.

Lithium batteries for Coos Bay go out of Shenzhen's Yantian and Shekou terminals. On the way they face a great-circle crossing of the North Pacific, and they arrive at the port of Coos Bay.
US entry is decided as much by paperwork filed in China as by anything at the port. 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
- Typhoon season Jun–Oct
- Yantian / Shekou export
- ISF filer
- Supply-chain tracing file
- HTS code 8507.60
Route profile
How Shenzhen → Coos Bay differs from other lanes
United States
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
5 pain points from Shenzhen to Coos Bay
Loading port first, then the sea leg, then Coos Bay and the United States market.
- Origin port
Dongguan's packaging certificate data is shared
Dongguan, home to more than 500 battery companies, supplies much of the cargo leaving Shenzhen. Since September 2026 Dongguan Customs and Dongguan MSA share dangerous-goods packaging certificate data, described as a first in China, and act jointly against concealed and false declarations; the one-box route to Yantian, 409 containers by then, relies on the same record.
What Anxin does: We compare the packaging certificate with the MSA cargo report (UN number, packaging code, number of packages) before either goes in, so the shared data shows no gap.
- Sea corridor
Hurricane-force winter storms, October to April
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.
- Import country
CPSC certificate data now filed at entry
Since 8 July 2026, importers of consumer products that are subject to a CPSC certification requirement must electronically file the certificate data at entry; goods entered from a Foreign Trade Zone follow on 8 January 2027. Whether a battery-powered product is caught depends on the rules that apply to that product, not on the battery alone.
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.
- Import country
AMS: the manifest CBP sees before the ship leaves Shenzhen
Under 19 CFR 4.7 the carrier's cargo declaration must be in CBP's Automated Manifest System 24 hours before loading abroad. Without it, or with inaccurate data, the permit to unlade the container at Coos Bay can be delayed or refused.
What Anxin does: We give the carrier or NVOCC the final cargo description, HS code, UN number and package count before the documentation cut-off in Shenzhen, so the AMS filing and the DG manifest say the same thing.
- Import country
Day 15 at the terminal: the General Order deadline
US customs rules give an unentered container 15 calendar days at the place of unlading. After that the carrier hands it to a bonded general order warehouse, with transport and storage at the consignee's risk and expense, and for DG cargo that needs specialized storage the port director decides where it is kept (19 CFR 4.37).
What Anxin does: We check with the importer's broker that the entry can be filed before arrival at Coos Bay, and chase any missing invoice or HTS detail while the ship is still at sea.
Documents & compliance
Documents to line up for Shenzhen → Coos Bay
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.
Before loading in Shenzhen
- 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
For the carrier and the 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 the importer in United States
- CPSC certificate data and eFiling arrangement, if the product is subject to certification
- Supply-chain tracing file for cells and lithium inputs, in case of a UFLPA request
- 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 Coos Bay.
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 |
|---|---|---|---|
| Packaging certificate and MSA filing disagree; shipment flagged | Dongguan → Yantian | Line-by-line comparison 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 |
| Permit to unlade delayed for a late or inaccurate AMS manifest | Port of discharge | Final cargo data given to the carrier before the cut-off | Carrier / NVOCC, with data from Anxin |
Questions
Shenzhen → Coos Bay: questions we are asked
No. The carrier must also send its cargo declaration through AMS 24 hours before loading, and CBP will not issue the permit to unlade without it.
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.
