Tianjin (Xingang)
North China's main container gateway, where Tianjin Customs lets DG containers be inspected at the factory and loaded on arrival within a booked port slot, and where the Bohai Bay freezes at its edges in mid-winter.

This route runs from North China through Tianjin Xingang, then follows a great-circle crossing of the North Pacific; at the far end is the port of Humboldt Bay.
The US side starts with two filings due before loading and ends with a road leg that must carry a live emergency number. This page sets out 5 points specific to this route, how Anxin handles each one and which documents to prepare.
What we need to start
- Bohai Bay winter ice
- Tianjin Xingang export
- Supply-chain tracing file
- HTS code 8507.60
- ISF filer
Route profile
How Tianjin → Humboldt Bay differs from other lanes
United States
A duty line set by the exact 8507.60 code, lithium supply-chain questions under UFLPA, and ISF and AMS filings that are due before the box is loaded.
Where this route gets difficult
What to watch between Tianjin and Humboldt Bay: 5 points
In the order the cargo meets them: at the loading port, at sea, at Humboldt Bay and at customs in United States.
- Origin port
Document review time at Tianjin and the cut-off
In July 2026 Tianjin MSA acknowledged that long document reviews under its traditional model often caused firms to miss the vessel's document cut-off, leaving cargo in port for another ship. The new appointment-based green channel, more than 50% faster with a fixed document list, is for new-energy-vehicle cargo; battery shipments should not count on it.
What Anxin does: We submit the cargo report with the full document set (safe-carriage declaration, SDS, packing certificate, packaging certificate) days before the cut-off rather than on the day, and treat any MSA query as same-day work.
- 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
Where the lithium came from: UFLPA questions at entry
Since August 2025 lithium has been a high-priority sector under the Uyghur Forced Labor Prevention Act, and CBP had by then stopped more than 16,700 shipments for UFLPA review. A container for Humboldt Bay can be held while the importer shows where the cells, cathode material and lithium compounds were sourced.
What Anxin does: We tell the importer at quotation stage that supply-chain tracing may be requested, and keep manufacturer names and addresses consistent across invoice, packing list and ISF so the paper trail does not contradict itself.
- Import country
Brand and chemistry labels on built-in-battery products
California has added battery-embedded products to its electronic-waste program: from 1 January 2026 buyers pay a recycling fee at purchase, and each covered product must show the manufacturer's name or brand and the battery chemistry (or put it on the maker's website), with an annual product notice to CalRecycle and retailers.
What Anxin does: If the goods landing at Humboldt Bay are devices with built-in batteries for sale in California, we ask the brand owner to confirm the chemistry labelling and the CalRecycle notice before shipping.
- 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 Humboldt Bay, and chase any missing invoice or HTS detail while the ship is still at sea.
Documents & compliance
Documents to line up for Tianjin → Humboldt Bay
Anxin reviews documents supplied by the shipper, manufacturer and importer; it does not issue test reports, safety data sheets or import certificates.
In Tianjin, before the box is loaded
- '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
- Transport-condition classification report where applicable
Carrier and voyage
- Stuffing photos before, during and after packing, checked for blocking and bracing
- 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
- Supply-chain tracing file for cells and lithium inputs, in case of a UFLPA request
- Importer of record and the licensed customs broker who will file the entry
- ISF filer named; stuffing location and consolidator sent right after packing
Before you book
Send the file once, complete
Most delays on this route start with a document that exists but does not match: a UN number, a model name or a package count that differs between the Tianjin filings, the carrier booking and the United States import file. We check the three against each other before the booking is confirmed.
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 |
|---|---|---|---|
| Document review runs past the vessel cut-off; cargo re-allocated to a later ship | Tianjin MSA review | Complete document set filed days before cut-off | Anxin with the declarant |
| Heavy-weather damage in a winter storm | North Pacific, Oct–Apr | CINS stuffing checks | Packing site, checked by Anxin |
| UFLPA detention pending supply-chain evidence | CBP at entry | Importer prepares tracing documents before shipping; consistent manufacturer data on all documents | Importer |
Questions
Common questions on the Tianjin → Humboldt Bay route
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.
The green channel Tianjin MSA announced in July 2026 is for new-energy-vehicle cargo. For battery containers we plan on the normal review and file early, because Tianjin MSA has said long reviews under the traditional model often cost firms their vessel cut-off.
