Lithium batteries for Sept-Îles go from the Pearl River Delta via Nansha. On the way they face a corridor into Atlantic Canada's waters, and they arrive at the port of Sept-Îles.
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 6 points specific to this route, how Anxin handles each one and which documents to prepare.
What we need to start
Route profile
Pearl River Delta battery cargo through Nansha, where a September 2026 agreement lets Dongguan-inspected containers load without a second MSA check, and where typhoon season runs June to October.
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
Loading port first, then the sea leg, then Sept-Îles and the Canada market.
In September 2026 Dongguan Customs and Dongguan MSA started sharing dangerous-goods packaging certificate data, described as a first in China, together with joint action against concealed and false declarations; Huangpu Customs also runs a joint 'lithium batteries going overseas' service against misdeclaration. A packaging certificate that does not match the MSA filing is now visible to both agencies.
What Anxin does: We check that the UN number, packaging code and quantities on the packaging certificate are exactly those on the MSA cargo report before either is submitted.
The tropical cyclone season in the region runs from June to October according to the Hong Kong Observatory, with July to September the busiest months. At Nansha, on the Pearl River mouth, a gate closure or a vessel change sends the DG filings and the packing certificate after the box to its new sailing.
What Anxin does: From June to October we leave slack between stuffing and the DG cut-off at Nansha and refile quickly if the vessel changes.
From December to May the Canadian Coast Guard breaks ice on the Gulf of St Lawrence and the river, and ships must clear with ECAREG CANADA 24 hours before entering, giving their ice class. Whether a winter sailing reaches Sept-Îles on time depends on the ship's ice capability and icebreaker routing.
What Anxin does: For December–May arrivals we ask the carrier whether the vessel or feeder serving Sept-Îles is ice-classed and build slack into delivery.
Canada accepts IMDG marking and documentation for the truck move out of Sept-Îles (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.
The CBSA's CARM transition ended in May 2025. Importer accounts with dutiable goods that had not posted financial security were removed from release prior to payment, and they now pay duties and taxes at release. An importer new to Sept-Îles has to settle this before the first container lands.
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.
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 Sept-Îles for French versions of descriptive wording before the order is packed.

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.

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 Guangzhou 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 |
|---|---|---|---|
| Mismatch between packaging certificate and MSA filing flagged by shared data | Dongguan / Nansha | Line-by-line check before submission | Anxin with the declarant |
| Typhoon closure after filings are made | Nansha, Jun–Oct | Slack in stuffing date; prompt refiling | Anxin with the declarant |
| Ice delays arrival or limits which vessels can call | Gulf of St Lawrence, Dec–May | Ice-classed vessel confirmed; slack in delivery | Carrier |
| Goods held at release until duties and taxes are paid | Canadian port of discharge | CARM security checked at quotation | Importer / broker |
Questions
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.
Both now have a one-box arrangement with Dongguan MSA: Yantian since May 2026 and Nansha since 22 September 2026, so a container inspected at the factory need not be reopened at the terminal unless necessary. The choice then comes down to the carrier's service to your destination and the cut-offs; we compare both when you book.

We check carrier acceptance for Guangzhou → Sept-Îles before any booking, and ask for missing battery documents first.
