As eCommerce continues to transform global trade, online sellers are increasingly looking to import products into Canada. Whether you run a Shopify store, sell through Amazon, or operate a niche direct-to-consumer site, customs compliance is a key part of the fulfillment process.
One of the most critical aspects of successful importing is document accuracy. Incomplete or incorrect paperwork can lead to delays, penalties, and even shipment seizures by the Canada Border Services Agency (CBSA). This article outlines the essential customs documents that every eCommerce business must prepare when importing goods into Canada.
1. Commercial Invoice
The commercial invoice is the backbone of your import documentation. It provides CBSA with a detailed breakdown of the transaction and helps determine the appropriate duties and taxes. A complete invoice should include:
- Seller and buyer contact information
- Detailed description of goods
- Quantity, unit price, and total value
- Currency of transaction
- Country of origin
- Incoterms (e.g., FOB, CIF)
To ensure smooth processing, the information on your commercial invoice must match the details declared in your customs entry.
2. Packing List
While not always mandatory, a packing list is highly recommended. It supports the commercial invoice by listing:
- Package contents and item breakdown
- Weight and dimensions
- Number of cartons or pallets
- Marks and numbers for each package
Customs officers may use the packing list to verify the physical contents of a shipment, especially during inspections.
3. Canada Customs Invoice (CCI)
For commercial shipments valued over CAD $2,500, importers are often required to submit a Canada Customs Invoice (CCI) or a commercial invoice containing all equivalent data points. The CCI helps CBSA assess the shipment for duty and tax calculation.
A CCI includes additional fields like:
- Terms of delivery and payment
- Vendor’s reference or invoice number
- Name and address of the purchaser and consignee
- Net and gross weight
More details can be found directly on the CBSA official website.
4. Import Declaration and B3 Form
Every commercial import must be declared to CBSA through the B3 Canada Customs Coding Form, either manually or electronically. This form details:
- HS codes and tariff classification
- Duty rates and applicable taxes (GST)
- Total value for duty
- Broker identification and transaction number
This document is usually prepared by a licensed Canadian customs broker, especially when shipments involve multiple tariff lines or complex valuation.

5. Other Supporting Documents
Depending on the nature of your eCommerce goods, you may also need:
- Certificates of Origin for free trade agreements (e.g., CUSMA/USMCA)
- Product compliance certificates (e.g., Health Canada, CFIA)
- Bill of Lading or Air Waybill from the carrier
- NAFTA/CUSMA Certificate if claiming preferential tariff treatment
In certain categories, such as cosmetics or food, additional regulatory filings may be required. It’s always wise to check with your customs broker or legal advisor ahead of time.
Conclusion
In the fast-paced world of eCommerce, failing to prepare the correct import documents can slow down your business and hurt your reputation with customers. Understanding what each document represents—and how it contributes to CBSA’s clearance process—is essential to ensuring seamless cross-border trade.
