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 out of Tianjin's Xingang terminals, where customs can supervise stuffing at the factory and the box goes straight to the ship on a booked slot, then follows a North Pacific crossing with no chokepoint but real winter-storm exposure; at the far end is the port of Vancouver (Washington).
US entry is decided as much by paperwork filed in China as by anything at the port. Below are 6 route-specific points to plan for, what we do about each, and the documents to have ready before booking.
What we need to start
- Factory-supervised loading
- Bohai Bay winter ice
- Supply-chain tracing file
- HTS code 8507.60
- ISF filer
Route profile
What sets Tianjin → Vancouver (Washington) apart
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
What to watch between Tianjin and Vancouver (Washington): 6 points
Loading port first, then the sea leg, then Vancouver (Washington) and the United States market.
- Origin port
Winter ice at the Haihe mouth
Sea ice forms every winter in the Bohai Sea, and the Haihe estuary at Tianjin is among the severe areas. In winter 2021/22 China's national marine forecast centre expected the peak ice period from mid-January to mid-February, with floating ice reaching about 5 nautical miles out in Bohai Bay. Ice and cold spells slow port operations around the Chinese New Year shipping peak.
What Anxin does: For January and February sailings from Tianjin we add slack between stuffing and the DG cut-off and confirm the vessel's berthing window with the carrier the week before loading.
- Origin port
Packaging appraisal comes first, even with Tianjin's quicker release
China requires use appraisal of export dangerous-goods packaging before the goods may be exported. Tianjin port's 2025 facilitation measures shortened packaging appraisal time for lithium battery exports through quick release, and Tianjin Port Group provides port services for lithium DG containers, but the appraisal certificate is still a precondition for the rest of the filing.
What Anxin does: We check at quotation that the packaging maker has its performance appraisal and apply for the use appraisal as soon as the packing is fixed, so the certificate is in hand before the MSA filing.
- Sea corridor
No chokepoint, but North Pacific storms
The drawn corridor from Tianjin 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
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 Vancouver (Washington) 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
Washington battery stewardship starts in 2027
From 1 January 2027 producers selling covered batteries or battery-containing products in or into Washington must be in an approved stewardship plan through a battery stewardship organization, or they may not sell there (RCW 70A.555). From 1 July 2027 retailers may not stock portable batteries unless the producer certifies it participates.
What Anxin does: When cargo through Vancouver (Washington) is sold in Washington, we flag the 2027 stewardship requirement to the importer at quotation so that retailer certification is in place in time.
- Import country
Product defects must be reported to CPSC within 24 hours
US importers, like manufacturers and retailers, must tell CPSC within 24 hours once they have information reasonably suggesting that a consumer product fails a safety rule or has a defect that could create a substantial hazard. Battery overheating reports from customers can trigger that duty, and CPSC expects any investigation to take no more than about 10 working days.
What Anxin does: We keep the manufacturer's batch records, UN 38.3 summaries and packing photos for each shipment to Vancouver (Washington), so the importer can answer CPSC questions quickly.
Documents & compliance
What to have ready: Tianjin to Vancouver (Washington)
These documents come from the shipper, the manufacturer and the importer. Anxin checks them against each other; it does not issue test reports, safety data sheets or import certificates.
In Tianjin, before the box is loaded
- Packaging use-appraisal certificate issued before the MSA cargo report is filed
- Load plan showing even weight distribution (no more than 60% of the cargo weight in either half of the container length)
- '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)
For the shipping line
- Stuffing photos before, during and after packing, checked for blocking and bracing
- Lithium battery mark (SP188 cargo) or class 9 labels and placards
- Condition statement: new, used, damaged/defective (SP376) or for recycling (SP377)
For the importer in United States
- Supply-chain tracing file for cells and lithium inputs, in case of a UFLPA request
- ISF filer named; stuffing location and consolidator sent right after packing
- HTSUS classification from the broker (8507.60.0010 vs .0020 decides the Section 301 line)
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
Risk table for Tianjin → Vancouver (Washington)
| Risk | Where | Mitigation | Who acts |
|---|---|---|---|
| Ice or cold spell slows berthing in mid-winter | Bohai Bay, Jan–Feb | Slack between stuffing and cut-off; berthing window reconfirmed | Carrier, monitored by Anxin |
| 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 |
| UFLPA detention pending supply-chain evidence | CBP at entry | Importer prepares tracing documents before shipping; consistent manufacturer data on all documents | Importer |
Questions
Tianjin → Vancouver (Washington): questions we are asked
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.
Tianjin Customs offers a 'supervised factory loading, direct loading on port arrival' model: stuffing is supervised at the factory, the box enters the port in a booked slot and is loaded directly. Whether a given shipment can use it depends on the customs arrangement for the exporter and the port slot; we check both when you book.
