An Ocean Shipment Is First a Paper Trail
The container travels, but it's the documentation that determines whether it will be released, cleared and delivered. Perfect cargo with inconsistent documents stays at the port. Conversely, a clean file lets a shipment move through without special intervention.
Here are the documents that come up in almost every shipment leaving Canada.
1. The Commercial Invoice
This is the transaction's foundational document. It states:
- seller and buyer (legal names, addresses);
- description of the goods;
- quantities and unit prices;
- total value and currency;
- Incoterm and place;
- payment terms.
Customs in the arrival country rely on this document to determine the declared value. A vague description ("assorted goods") is one of the most common causes of questions and delays.
2. The Packing List
This describes what is physically inside the container: number of packages, bales or pallets, contents of each, gross and net weight, dimensions.
It must be consistent with the invoice. If the invoice lists 500 units and the packing list shows 480, the discrepancy will need to be explained.
3. The Bill of Lading
The central document of ocean transport. It serves three functions:
- Receipt for the goods taken into custody;
- Evidence of the contract of carriage;
- Document of title to the goods, whose presentation allows delivery to be claimed.
For this last reason, a bill of lading must be handled carefully: depending on its form, an original may be required at destination to release the container.
Always verify, before final issuance: exact name of the consignee, port of loading and discharge, description of the goods, number of packages, weight, container and seal numbers.
4. The Export Declaration
Depending on the nature, value and destination of the goods, an export declaration may be required when leaving Canada. It is filed before the vessel departs; leaving it to the last minute risks delaying loading.
5. The Certificate of Origin
Required by many countries, it certifies the country of origin of the goods. It can affect the duty rate applied on arrival. It is generally issued or certified by a chamber of commerce.
6. Specific Certificates and Inspections
Depending on the product and destination, you may need:
- a pre-shipment inspection certificate, required by certain countries;
- sanitary or phytosanitary documents for certain categories;
- specific documents for vehicles (see Vehicle Export Documents in Canada);
- requirements specific to used textiles in certain countries.
This should be checked at the time of booking, not after.
7. The Cargo Insurance Certificate
If the goods are insured, the insurance certificate or attestation is part of the file. See our article Marine Cargo Insurance: What It Covers.
Who Issues What
- Seller / exporter: commercial invoice, packing list, certificate of origin (via the relevant body).
- Forwarder / shipping line: bill of lading, booking confirmation.
- Inspection body: inspection certificate.
- Insurer: insurance certificate.
- Buyer / consignee: local import documents, customs broker authorization.
The Most Costly Mistakes
- Inconsistent descriptions across invoice, packing list and bill of lading.
- Incomplete consignee name, or one that differs from their official registration.
- Approximate declared weight: a source of disputes and correction fees.
- Original bill of lading sent too late: the container waits, and storage fees pile up.
- A required certificate discovered after loading.
Best Practice: Cross-Checking Before Departure
Before loading, review the invoice, packing list and draft bill of lading side by side. Confirm that the same five pieces of information appear everywhere: description, quantity, weight, consignee, destination. Five minutes of review can prevent weeks of delay.
Our team handles this stage directly: see our container booking service in Montreal for how the service works from Montreal.
FAQ
How far ahead of departure should documents be finalized? Bill of lading instructions and weight data are due by specific deadlines before departure. It's wise to finalize everything several days ahead, not the night before.
Do I need an original bill of lading or an electronic version? That depends on the type of bill of lading chosen and requirements at destination. We discuss this at the time of booking.
What happens if there's an error on the bill of lading? Corrections are possible, but the closer the vessel is to departure or arrival, the more complex and costly they become. Checking beforehand remains the best solution.
