Understanding Canadian Customs and Import Duties
Shipping across borders involves more than just choosing a carrier. Whether you're importing goods into Canada or sending a package from Canada abroad, customs regulations play a major role. This guide explains the key concepts so you can ship with confidence.
What Is a Customs Declaration?
A customs declaration is a form that describes the contents, value, and origin of your shipment. It allows customs authorities to assess whether duties or taxes apply. For international shipments, this document is mandatory — without it, your parcel can be held indefinitely at the border.
Key information required on a customs form:
- Description of contents (be specific — "gift" is not sufficient)
- Quantity and weight of items
- Declared value in Canadian or US dollars
- Country of origin of the goods
- Whether it's a gift, commercial sample, or sold item
When Are Duties and Taxes Applied?
Canada Border Services Agency (CBSA) applies duties and taxes based on the value and type of goods. Here's a general overview:
| Import Value (CAD) | Duty/Tax Treatment |
|---|---|
| Under $20 | Generally duty-free and tax-free (de minimis threshold) |
| $20–$150 (from US/Mexico) | Duty-free under CUSMA; GST/HST may still apply |
| Over $150 (from US/Mexico) | Duties and GST/HST apply based on product category |
| From other countries | Full duties and taxes apply above $20 |
Note: Thresholds and rates can change. Always verify current rules with the CBSA website before shipping.
The Canada–US–Mexico Agreement (CUSMA)
Under CUSMA (formerly NAFTA), many goods traded between Canada, the US, and Mexico qualify for reduced or zero duties — but only if they meet the rules of origin requirements. To claim preferential treatment, you may need to provide a Certificate of Origin or a written declaration on your invoice.
Prohibited and Restricted Items
Not everything can be shipped into or out of Canada. Common restricted or prohibited items include:
- Firearms and weapons (require permits)
- Certain food products, plants, and soil
- Alcohol and tobacco (restricted quantities)
- Counterfeit goods
- Certain chemicals and hazardous materials
Always check the CBSA's prohibited goods list and your carrier's restricted items policy before shipping unfamiliar goods.
Tips to Avoid Customs Delays
- Be accurate and detailed on your customs declaration — vague descriptions cause holds.
- Include a commercial invoice for any goods with a monetary value.
- Use the correct HS (Harmonized System) tariff codes to classify your goods properly.
- Declare the actual value — undervaluing goods is illegal and can result in fines or seizure.
- Work with a licensed customs broker for high-value or complex commercial shipments.
Who Pays Duties — Sender or Recipient?
By default, the recipient pays any applicable duties and taxes when the package is delivered. However, shippers can choose Delivered Duty Paid (DDP) as a shipping option, meaning the sender covers all import costs upfront. DDP creates a better experience for the recipient and avoids surprise charges at the door.
Understanding customs before you ship saves time, money, and frustration. When in doubt, consult the CBSA directly or use a freight broker with customs expertise.
