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.

Lithium batteries for Coal Harbour go through Tianjin, with its Beijiang and Dongjiang terminals on the Bohai Bay. On the way they face the open North Pacific, where weather is the main risk, and they arrive at the port of Coal Harbour.
On the Canadian side the carrier's eManifest is due before loading and the road leg follows TDG conditions. 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
Route profile
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.
No canal or Red Sea passage, but a North Pacific crossing where winter storms have collapsed container stacks.


Where this route gets difficult
Listed from loading in Tianjin to import into Canada, each with what we do about it.
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.
Tianjin MSA itself said in July 2026 that, under the traditional review model, long document reviews often made firms miss the vessel's document cut-off, leaving cargo in port to be re-allocated to another ship. Its new fast-track green channel (appointment-based, more than 50% faster, with a fixed document list) is for new-energy-vehicle cargo; battery shipments should not assume they qualify.
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.
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.
British Columbia's 2025 recycling amendments bring products that contain or use batteries of 5 kg or less, portable power stations and separately sold replacement batteries under producer responsibility. Producers must file an EPR plan by 15 December 2026 and run the program from 1 October 2027.
What Anxin does: For goods sold in British Columbia after landing at Coal Harbour, we flag the 2026 plan deadline to the importer so the brand owner's EPR membership is settled before the program starts.
Under s. 14 of the Canada Consumer Product Safety Act, an importer that learns of a health or safety incident involving a consumer product must tell Health Canada and its supplier within two days, and file a written report within ten. For battery products sold in Canada, the Chinese supplier's test and batch data are needed quickly.
What Anxin does: We make sure the importer has the manufacturer's contact, batch identifiers and test reports on file with each shipment, so an incident report can be made on time.

Documents & compliance
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.

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 Canada 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 | 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 |
| 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 |
| Heavy-weather damage in a winter storm | North Pacific, Oct–Apr | CINS stuffing checks | Packing site, checked by Anxin |
Questions
Yes. TDG s. 9.3 allows IMDG documentation and marks for an international consignment going to or from a port, provided the document is legible in English or French and carries a 24-hour number.
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.

We check carrier acceptance for Tianjin → Coal Harbour before any booking, and ask for missing battery documents first.
