This route runs from the Yangtze River Delta via Shanghai's Yangshan and Waigaoqiao terminals, then follows a corridor into Atlantic Canada's waters; at the far end is the port of Churchill.
Canadian clearance depends on eManifest data filed before loading and on the importer's CARM set-up. 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
- Photo-verified packing certificate
- Yangshan / Waigaoqiao export
- CARM account
- Bilingual labels
- eManifest cut-off
Route profile
How Shanghai → Churchill differs from other lanes
Canada
Container data due 24 hours before loading, CARM security for release before payment, and a road leg that accepts IMDG papers under Canadian conditions.
Where this route gets difficult
What to watch between Shanghai and Churchill: 5 points
Listed from loading in Shanghai to import into Canada, each with what we do about it.
- Origin port
Shanghai checks during and after the voyage filing, not just before
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.
- Origin port
Not every Shanghai warehouse can stuff lithium DG
Shanghai MSA's 2024 draft reporting guide says warehouses that stuff lithium battery dangerous goods must provide fire-department proof of their fire hazard classification and fire-resistance rating. The site's information must also be up to date on the Shanghai single window, which took over MSA account and site records in 2026.
What Anxin does: We only propose stuffing sites that can show the fire-safety documents and are on Shanghai MSA's system; if you use your own warehouse, we check this before booking.
- Sea corridor
January is the peak of North Atlantic winter storms
NOAA's Ocean Prediction Center has logged hurricane-force mid-latitude storms in the North Atlantic from October to April, most frequently in January, on the last leg of the voyage to Churchill.
What Anxin does: For winter sailings we check blocking and bracing on stuffing photos before sealing.
- Import country
A late eManifest correction restarts the 24-hour clock
Canada's advance commercial information rules want container data from the carrier 24 hours before loading abroad. Change the data electronically before the ship sails and the 24 hours run again from the CBSA's acknowledgement, which is how a correction made in Shanghai can cost a container its sailing.
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.
- Import country
Incidents must be reported within two days
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
What to have ready: Shanghai to Churchill
Anxin reviews documents supplied by the shipper, manufacturer and importer; it does not issue test reports, safety data sheets or import certificates.
Before loading in Shanghai
- Stuffing site registered and geo-verified with Shanghai MSA; fire-safety proof for lithium DG warehouses
- Per-container evidence file (UN38.3 summary, SDS, photos, short-circuit protection) kept for Shanghai MSA spot checks
- Bilingual (English/French) retail labelling checked on artwork
- 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)
Carrier and voyage
- Final cargo data with the carrier before the eManifest cut-off; no amendments after filing
- Lithium battery mark (SP188 cargo) or class 9 labels and placards
- Condition statement: new, used, damaged/defective (SP376) or for recycling (SP377)
For import into Canada
- Importer's CARM account and release-prior-to-payment security confirmed
- English DG documents with a 24-hour number for the Canadian road leg
Before you book
One consistent file
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 Shanghai 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.

| 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
Common questions on the Shanghai → Churchill route
At least 24 hours before loading in China. If the data are amended electronically before the ship sails, the 24 hours restart from the CBSA's acknowledgement.
NOAA's storm study found hurricane-force winter storms from October to April, most often in January.
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.
