# [Understanding rules of origin when importing into Canada](https://blog.coleintl.com/import-foundations/understanding-rules-of-origin-when-importing-into-canada)

Getting rules of origin wrong, even unintentionally, may result in reassessments, unexpected duty costs, and AMPS penalties.

When importing goods into Canada, **rules of origin** determine where a product is considered to originate for customs purposes. This can directly affect the duty rate you pay and whether you qualify for preferential tariff treatment under a free trade agreement.

Rules of origin are not always based on where the goods were shipped from or purchased, which is where many importers run into trouble.

When origin is declared incorrectly, it can lead to reassessments by the Canada Border Services Agency (CBSA), additional duties, [AMPS penalties](https://blog.coleintl.com/import-foundations/avoiding-amps-penalties-when-importing-into-canada), and compliance issues.

In this article, we explain what rules of origin are and five common mistakes to avoid.

## **What rules of origin are and how they work**

Rules of origin are the criteria used to establish the [economic nationality of goods](https://www.wto.org/english/tratop_e/roi_e/roi_e.htm). In Canada, rules of origin determine which tariff treatment you can claim on imported goods.

Because each [tariff treatment](https://blog.coleintl.com/import-foundations/understanding-canadas-tariff-treatments-for-imported-goods) is linked to specific rules of origin, goods must first be classified according to the Harmonized Commodity Description and Coding System.

There are two types of rules of origin:

1. **Non-preferential:** applies to most imports and determines the [country of origin](https://blog.coleintl.com/import-foundations/what-country-of-origin-means-and-how-its-determined) for general customs purposes, including which [MFN](https://blog.coleintl.com/import-foundations/what-is-the-most-favoured-nation-mfn-tariff-rate-in-canada) duty rate applies and whether anti-dumping or countervailing duties ([AD/CVD](https://blog.coleintl.com/import-foundations/what-are-anti-dumping-and-countervailing-duties)) are owed.
2. **Preferential:** applies under Canada's free trade agreements and must be satisfied to claim a reduced or zero duty rate.

For goods produced using materials from more than one country, origin depends on whether the applicable rule of origin is met.

Depending on the tariff treatment being claimed, this may involve a change in tariff classification, a regional value content requirement, or another product-specific rule set out in the applicable agreement or regulation.

## **5 common rules of origin mistakes**

As the [importer of record](https://blog.coleintl.com/import-foundations/what-it-means-to-be-the-importer-of-record-in-canada), you are responsible for ensuring the origin claim is accurate and can be supported. Here are five common mistakes that can put that claim at risk:

### 1. Relying only on supplier declarations

A supplier certificate of origin or origin declaration is only the starting point. This is especially important when claiming [preferential tariff treatment](https://blog.coleintl.com/import-foundations/how-to-claim-preferential-tariff-treatment-with-a-certificate-of-origin), where the goods must meet the rule of origin in the applicable FTA. Always verify that the claim is accurate and supportable before using it.

### 2. Overlooking the link between tariff classification and origin

The rule of origin that applies to your goods is tied to the tariff item, so an incorrect tariff classification can lead you to apply the wrong rule. Confirm the [HS code](https://blog.coleintl.com/import-foundations/importing-into-canada-heres-how-to-find-your-hs-code) first to ensure the tariff treatment claim is based on the correct rule.

### 3. Confusing shipping origin with country of origin

Goods shipped from a particular country are not necessarily originating from that country. Determine origin based on the applicable rules, not the country of shipment or [transshipment](https://blog.coleintl.com/freight-fundamentals/understanding-transshipment-in-global-shipping).

### 4. Assuming preferential treatment applies automatically

Preferential tariff treatment is not applied automatically. You must declare the origin of your goods on the [CAD](https://blog.coleintl.com/import-foundations/how-to-account-for-your-imports-using-the-commercial-accounting-declaration-cad)<https://blog.coleintl.com/import-foundations/how-to-account-for-your-imports-using-the-commercial-accounting-declaration-cad><https://blog.coleintl.com/import-foundations/how-to-account-for-your-imports-using-the-commercial-accounting-declaration-cad>using the relevant two-digit [tariff treatment code](https://blog.coleintl.com/import-foundations/understanding-canadas-tariff-treatments-for-imported-goods). If no claim is made at the time of accounting, MFN duties apply by default.

### 5. Failing to retain supporting documentation

Even when the origin claim is correct, missing documentation can leave you unable to support it during a CBSA verification. Origin records and supporting documents must be [retained for six years](https://blog.coleintl.com/blog/how-long-should-you-keep-your-import-records).
