From Shanghai to Shelburne, cargo moves from the Yangtze River Delta via Shanghai's Yangshan and Waigaoqiao terminals, crosses a corridor through the Panama Canal, and is discharged at the port of Shelburne.
Canada adds an eManifest that closes 24 hours before loading and a CARM account that decides whether goods are released before duty is paid. 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
Route profile
A Pacific crossing, a Panama Canal transit that depends on lake levels, and a Caribbean passage in hurricane season.
An eManifest filed 24 hours before loading, release-before-payment only with CARM security, and TDG conditions on the truck leg.


Where this route gets difficult
In the order the cargo meets them: at the loading port, at sea, at Shelburne 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.
At Shanghai the packing inspector must upload photos taken before, during and after stuffing through the MSA's remote system, with face recognition and phone location on, before the electronic packing certificate goes out by EDI. A container is not loaded if the photos are missing, uploaded late, taken outside the verified stuffing site, or do not match the EDI cargo data. Stuffing sites outside Shanghai must be registered with Shanghai MSA.
What Anxin does: We confirm that the stuffing site (including factory sites in Jiangsu or Zhejiang) is registered for Shanghai's remote system, and we check the photo upload against the EDI data before the packing certificate is sent.
NOAA's Ocean Prediction Center has recorded hurricane-force North Pacific storms in every month from October to April, most often in December. The Pacific leg to Panama crosses that ocean.
What Anxin does: For October–April sailings we check blocking and bracing on stuffing photos before sealing.
Canada accepts IMDG marking and documentation for the truck move out of Shelburne (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.
Nova Scotia requires producers of household batteries under 5 kg to run or join an approved stewardship program. Since 1 July 2024 brand owners fund and manage it, and retailers may not sell batteries from brand owners who are not in a program.
What Anxin does: For household batteries arriving at Shelburne for Nova Scotia retail, we ask whether the brand owner participates in the approved program before booking.

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.

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 Shanghai 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 |
|---|---|---|---|
| Container refused for loading: photos late, off-site or not matching EDI data | Yangshan / Waigaoqiao | Photo upload checked against EDI data before the certificate is sent | Packing inspector, checked by Anxin |
| Post-event spot check finds missing proof | Shanghai MSA | Evidence file kept per container | Shipper with Anxin |
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.
It can. In September 2026 the Panama Canal Authority postponed a planned draft cut in the Neopanamax locks because of Gatun Lake levels (advisory A-33-2026). We check the advisory in force when quoting.
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.

We check carrier acceptance for Shanghai → Shelburne before any booking, and ask for missing battery documents first.
