Lithium batteries for Montreal go through Yangshan or Waigaoqiao under Shanghai MSA's photo-verified packing rules. On the way they face a corridor into Atlantic Canada's waters, and they arrive at the port of Montreal.
Canadian clearance depends on eManifest data filed before loading and on the importer's CARM set-up. 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
Route profile
Yangshan and Waigaoqiao exports under Shanghai MSA's photo-verified packing system, where a mismatch between photos and EDI data keeps a DG box off the ship.
Canada checks the carrier's eManifest before loading, the importer's CARM security at release and, for consumer goods, bilingual labels.


Where this route gets difficult
They run from the Shanghai terminal through the voyage to Montreal and the Canada import file.
At Shanghai the packing inspector must upload photos taken before, during and after stuffing through the MSA's remote system, with face recognition and phone location on, before the electronic packing certificate goes out by EDI. A container is not loaded if the photos are missing, uploaded late, taken outside the verified stuffing site, or do not match the EDI cargo data. Stuffing sites outside Shanghai must be registered with Shanghai MSA.
What Anxin does: We confirm that the stuffing site (including factory sites in Jiangsu or Zhejiang) is registered for Shanghai's remote system, and we check the photo upload against the EDI data before the packing certificate is sent.
Shanghai MSA's Notice No. 4 of 2024 accepts either an inspector-signed packing certificate or a packing declaration from the stuffing company, but places the burden on the shipper: the batteries must meet the UN tests and be protected against damage, short circuit and accidental activation, and MSA runs spot checks during and after the process, with proof to be produced on request.
What Anxin does: We keep a file per container (UN38.3 summary, SDS, packing photos, terminal protection details) so that proof can be produced the same day if Shanghai MSA asks for it after sailing.
The Atlantic hurricane season runs from 1 June to 30 November, peaking around 10 September, with most activity from mid-August to mid-October.
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 Montreal 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 Shanghai and avoid amendments after the filing.
Canada accepts IMDG marking and documentation for the truck move out of Montreal (TDG s. 9.3), provided the shipping document is legible in English or French, gives a 24-hour number and the container is placarded under TDG Part 4 or the IMDG Code.
What Anxin does: We check that the DG declaration is in English, carries a 24-hour number that the consignee has arranged and matches the container's placards before the documents go to the Canadian trucker.
Since 1 June 2025, Québec lets recognised non-French trademarks stay untranslated on products, but any generic or descriptive words in them must appear in French on the product or a permanently attached medium. Stock made before that date can be sold until 1 June 2027.
What Anxin does: We check product and packaging artwork for goods going to Montreal for French versions of descriptive wording before the order is packed.

Documents & compliance
Anxin reviews documents supplied by the shipper, manufacturer and importer; 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 Shanghai 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 |
|---|---|---|---|
| Container refused for loading: photos late, off-site or not matching EDI data | Yangshan / Waigaoqiao | Photo upload checked against EDI data before the certificate is sent | Packing inspector, checked by Anxin |
| Post-event spot check finds missing proof | Shanghai MSA | Evidence file kept per container | Shipper with Anxin |
| Container rolled after a late eManifest amendment | Loading port | Data final before filing | Carrier, with data from 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.
Yes, but the Coast Guard's icebreaking season on the Gulf of St Lawrence and the river typically runs from December to May, and vessels must report their ice class to ECAREG CANADA. We confirm the vessel's ice capability when booking.
Shanghai MSA's Notice No. 4 of 2024 accepts either an inspector-signed packing certificate or a packing declaration issued by the stuffing company. Either way, the shipper remains responsible and must provide proof if MSA spot-checks.
