Accurate import documentation allows the carrier, customs professional and receiving warehouse to describe the same goods in the same way. A commercial invoice and packing list are essential starting points, but permits and origin documents can matter for certain products.
Start with the commercial invoice
The invoice should clearly identify parties, goods, price, currency, quantities and the transaction. Descriptions must be specific enough to support classification and valuation. Generic wording such as “samples” or “miscellaneous merchandise” can be inadequate for customs purposes.
Add the packing and transport records
A packing list helps locate goods by carton, pallet or package and usually records quantities, dimensions and weights. Transport documentation—such as an air waybill or bill of lading—identifies carriage details. These documents should match the invoice and shipment instructions closely enough for parties to reconcile them.
Include origin and regulatory evidence
Depending on the product, the importer may need origin support, permits, certificates, inspection documents or other agency-specific records. Freight documents alone do not prove that goods satisfy Canadian admissibility requirements. Confirm requirements against the exact commodity before the supplier dispatches it.
Keep accounting and payment proof
After release and accounting, save customs declaration details, the transaction reference, relevant CARM entries and payment confirmation. Corrections and adjustments should be traceable to the original transaction. CBSA generally requires commercial importers to retain relevant records for six years following importation.
Perform a cross-document validation
Compare item descriptions, quantities, values, currency and trade terms on the invoice with carton counts, marks, weights and dimensions on the packing list. Confirm the importer BN15, transport documents and any required permits or origin statements. Use item codes that are consistent across the purchase order and customs instructions.
An invoice describing goods only as 'parts' may be insufficient for the correct tariff classification. Ask the supplier for actual material, function and model details before pickup. When a shipment changes after documents are prepared, issue corrected versions to every party rather than leaving conflicting copies in circulation.
Practical checklist
- Obtain a detailed commercial invoice.
- Match quantities to the packing list.
- Confirm transport and importer references.
- Collect applicable origin and permit records.
- Preserve customs declarations and payments.
An example in practice
A shipment of imported appliances has ten cartons. The purchase order, invoice and packing list all describe the same ten units, while the transport document records carriage details and the import file contains applicable compliance evidence.
Frequently asked questions
Is a packing list always enough for customs?
No. Importers generally need commercial, transport and any commodity-specific records.
Can I use vague product descriptions?
Avoid them; accurate classification and compliance depend on specific goods information.
Can a packing list replace the commercial invoice?
No. The packing list describes physical packages; the invoice supports the commercial transaction and customs value.
