Lithium batteries for Roberts Bank go through Yangshan or Waigaoqiao under Shanghai MSA's photo-verified packing rules. On the way they face the open North Pacific, where weather is the main risk, and they arrive at the port of Roberts Bank.
On the Canadian side the carrier's eManifest is due before loading and the road leg follows TDG conditions. Below are 5 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
A North Pacific crossing with no canal or chokepoint risk, but with a record of winter storms strong enough to collapse container stacks.
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
In the order the cargo meets them: at the loading port, at sea, at Roberts Bank and at customs in Canada.
Shanghai MSA's Notice No. 4 of 2024 lets the shipper use either an inspector-signed packing certificate or a packing declaration from the stuffing company, but the responsibility stays with the shipper: UN-tested batteries, protected against damage, short circuit and accidental activation. MSA spot-checks during and after the process and can ask for proof.
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.
NOAA's Ocean Prediction Center found hurricane-force winds (64 knots and above) in North Pacific mid-latitude storms in every month from October to April, peaking in December, with 15 to 23 such storms per season in its 2001–2004 records. They are not typhoons, so they do not follow the tropical calendar.
What Anxin does: For October–April sailings we check blocking and bracing on stuffing photos before sealing and confirm the full DG data are on the manifest.
The Vancouver Fraser Port Authority, with other agencies, requires pre-notification before dangerous goods move within the port. Applications for dangerous goods acceptance go through its Pacific Gateway Portal, and handling must follow the Canada Shipping Act and the TDG Act.
What Anxin does: We give the carrier and its agent the complete DG data for Roberts Bank early enough for the port authority's acceptance process, and pass the same data to the consignee's 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 Roberts Bank 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.
British Columbia's 2025 recycling amendments bring products that contain or use batteries of 5 kg or less, portable power stations and separately sold replacement batteries under producer responsibility. Producers must file an EPR plan by 15 December 2026 and run the program from 1 October 2027.
What Anxin does: For goods sold in British Columbia after landing at Roberts Bank, we flag the 2026 plan deadline to the importer so the brand owner's EPR membership is settled before the program starts.

Documents & compliance
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.

We line up UN numbers, model names and package counts across the Shanghai filings, the booking with the carrier and the documents for Canada before the booking is confirmed, so that a mismatch is fixed at origin rather than discovered at Roberts Bank.
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 |
|---|---|---|---|
| Post-event spot check finds missing proof | Shanghai MSA | Evidence file kept per container | Shipper with Anxin |
| Heavy-weather damage in a winter storm | North Pacific, Oct–Apr | CINS stuffing checks | Packing site, checked by Anxin |
| 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.
Weather is the main risk on this crossing: NOAA recorded hurricane-force North Pacific storms from October to April, most often in December. We tighten the packing checks for those sailings.
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.
