Lithium batteries for Churchill 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 long voyage ending in the North Atlantic or the Gulf of St Lawrence, and they arrive at the port of Churchill.
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

The Shenzhen → Churchill route in brief
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
5 points to plan for on the Shenzhen → Churchill route
Loading port first, then the sea leg, then Churchill and the Canada market.
- 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.
- Origin port
Typhoon season squeezes Shenzhen cut-offs
The Hong Kong Observatory puts the regional tropical cyclone season from June to October, busiest July to September. DG containers need their MSA filings approved and a signed packing certificate before loading, so a closed gate or a rolled vessel in typhoon weeks can push the whole document chain to a new sailing.
What Anxin does: From June to October we build slack into the stuffing date, confirm the DG cut-off with the carrier the week before loading, and resubmit filings promptly if the vessel changes.
- Sea corridor
Late-summer hurricanes on the Atlantic approach
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 Churchill.
What Anxin does: For August–October arrivals we plan slack and pass the carrier's revised arrival to your consignee.
- Import country
Release before payment needs security posted in CARM
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 Churchill, 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.
- 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: Shenzhen to Churchill
Test reports, safety data sheets and import certificates come from the shipper, factory and importer, not from Anxin; our part is to review them before booking.
Before loading in Shenzhen

- 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)
- Container packing certificate signed by a certified packing inspector after supervised stuffing
For the shipping line
- Final cargo data with the carrier before the eManifest cut-off; no amendments after filing
- Condition statement: new, used, damaged/defective (SP376) or for recycling (SP377)
- UN 38.3 test summary for every cell and battery type
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
Send the file once, complete
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 Shenzhen 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
What could go wrong from Shenzhen to Churchill, and who acts
| Risk | Where | Mitigation | Who acts |
|---|---|---|---|
| Typhoon closes terminals or delays the vessel after filings are made | Yantian / Shekou, Jun–Oct | Slack in stuffing date; refile quickly on vessel change | Anxin with the declarant |
| Packaging certificate and MSA filing disagree; shipment flagged | Dongguan → Yantian | Line-by-line comparison before filing | Anxin with the declarant |
| Goods held at release until duties and taxes are paid | Canadian port of discharge | CARM security checked at quotation | Importer / broker |
Questions
Common questions on the Shenzhen → Churchill 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.
NOAA's storm study found hurricane-force winter storms from October to April, most often in January.
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.
