Lithium batteries for Digby go from Dongguan and Shenzhen factories via Yantian, where the one-box route had moved 409 battery containers by September 2026. On the way they face a corridor through the Panama Canal, and they arrive at the port of Digby.
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
- Typhoon season Jun–Oct
- Yantian / Shekou export
- Bilingual labels
- eManifest cut-off
- CARM account

Where this route gets difficult
5 points to plan for on the Shenzhen → Digby route
Listed from loading in Shenzhen to import into Canada, each with what we do about it.
- Origin port
Packaging certificates are now visible to both customs and MSA
Much of Shenzhen's battery cargo is made in Dongguan, home to more than 500 battery firms. In September 2026 Dongguan Customs and Dongguan MSA began sharing dangerous-goods packaging certificate data, described as a first in China, and committed to joint action against concealed and false declarations. The one-box route to Yantian, which had moved 409 containers by then, rests on that same record.
What Anxin does: We compare the packaging certificate with the MSA cargo report (UN number, packaging code, number of packages) before either goes in, so the shared data shows no gap.
- Sea corridor
Panama's draft limit depends on the lake
The Panama Canal Authority sets the maximum draft in the Neopanamax locks according to Gatun Lake levels. In September 2026 it postponed a planned cut from 14.63 m to 14.48 m that was due on 1 October (advisory A-33-2026). A lower limit means ships transiting the new locks can load less.
What Anxin does: We check the canal advisory in force when we quote for Digby and ask carriers to confirm that the booked vessel's routing and any canal surcharge will not change before sailing.
- 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.
- 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 Shenzhen 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 Shenzhen and avoid amendments after the filing.
- Import country
A 24-hour number and English or French documents for the Canadian road leg
Canada accepts IMDG marking and documentation for the truck move out of Digby (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.

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 Shenzhen 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
What could go wrong from Shenzhen to Digby, and who acts
| Risk | Where | Mitigation | Who acts |
|---|---|---|---|
| Packaging certificate and MSA filing disagree; shipment flagged | Dongguan → Yantian | Line-by-line comparison before filing | Anxin with the declarant |
| Draft cut reduces capacity or adds surcharges | Panama Canal | Advisory checked at quotation; carrier confirmation | Carrier, checked by Anxin |
| Container rolled after a late eManifest amendment | Loading port | Data final before filing | Carrier, with data from Anxin |
Questions
Common questions on the Shenzhen → Digby route
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.
1 June to 30 November, peaking around 10 September, according to the US National Hurricane Center.
Since September 2026 Dongguan Customs and Dongguan MSA share dangerous-goods packaging certificate data and act jointly against false declarations, so the packaging certificate and the MSA filing should match exactly.
