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 St. John's go through Tianjin, with its Beijiang and Dongjiang terminals on the Bohai Bay. On the way they face a long voyage ending in the North Atlantic or the Gulf of St Lawrence, and they arrive at the port of St. John's.
Canada adds an eManifest that closes 24 hours before loading and a CARM account that decides whether goods are released before duty is paid. 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
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.
A final leg through North Atlantic or St Lawrence waters, with ice from December to May and winter storms that peak in January.


Where this route gets difficult
Loading port first, then the sea leg, then St. John's and the Canada market.
Every winter the Bohai Sea ices over, and the Haihe estuary at Tianjin is one of the harder-hit areas. For 2021/22 the national marine forecast centre put the peak ice period between mid-January and mid-February, with floating ice about 5 nautical miles out in Bohai Bay. Ice and cold slow port work just as the Chinese New Year peak arrives.
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.
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.
Atlantic hurricanes run from 1 June to 30 November, with the peak around 10 September and most storms between mid-August and mid-October, on the approach to St. John's.
What Anxin does: For August–October arrivals we plan slack and pass the carrier's revised arrival to your consignee.
The CBSA requires marine carriers to transmit cargo and conveyance data for containers at least 24 hours before loading at the foreign port, including the estimated loading time. If the data are amended electronically before departure, the 24-hour count starts again from the CBSA's acknowledgement, so a late correction can push a box for St. John's off its vessel.
What Anxin does: We send the carrier the final cargo description, UN number, weights and consignee details before the cut-off in Tianjin and avoid amendments after the filing.
Since the CARM transition ended on 20 May 2025, importers without financial security posted in the CARM Client Portal no longer get release prior to payment; they pay duties and taxes when the goods are released. For a first shipment through St. John's, that decides whether goods can leave the terminal before the duty is settled.
What Anxin does: At quotation we ask the Canada importer whether its CARM account has security posted for release prior to payment, so the broker's release plan is known before the ship arrives.

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.

A document that is present but inconsistent holds a booking as surely as a missing one: the UN number, model name or carton count reads differently in the Tianjin export filings, the carrier booking and the Canada import papers. We compare all three before confirming space.
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 |
|---|---|---|---|
| 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 |
| 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 |
| Container rolled after a late eManifest amendment | Loading port | Data final before filing | Carrier, with data from Anxin |
| Goods held at release until duties and taxes are paid | Canadian port of discharge | CARM security checked at quotation | Importer / broker |
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.
NOAA's storm study found hurricane-force winter storms from October to April, most often in January.
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 → St. John's before any booking, and ask for missing battery documents first.
