USMCA Rules of Origin: Qualifying for Preferential Rates

Why USMCA Rules of Origin Matter

The United States-Mexico-Canada Agreement (USMCA) provides duty-free or reduced-duty access for goods that qualify as originating in North America. For US importers, this means potentially saving thousands or millions of dollars in duties on goods from Mexico and Canada — but only if you can prove the goods meet the agreement’s rules of origin.

Rules of origin are the criteria used to determine where a product was “made” for trade purposes. A product assembled in Mexico using components from China and Germany is not automatically “Mexican” under USMCA. The product must undergo sufficient processing or contain sufficient North American content to qualify.

Three Methods of Qualification

USMCA provides three main methods to determine if a product qualifies as originating. The applicable method depends on the specific product and its HTS classification. The product-specific rules are listed in Annex 4-B of the agreement.

1. Tariff Shift: The product must undergo a change in tariff classification (at the chapter, heading, or subheading level) from its non-originating materials. For example, raw steel (Chapter 72) manufactured into steel tools (Chapter 82) in Mexico satisfies a chapter-level tariff shift.
2. Regional Value Content (RVC): The product must contain a minimum percentage of North American value, calculated using either the Transaction Value method (typically 50-60%) or the Net Cost method (typically 40-50%). The formula is: RVC = ((AV - VNM) / AV) x 100, where AV is the adjusted value and VNM is the value of non-originating materials.
3. Wholly Obtained or Produced: The product is entirely grown, harvested, extracted, or manufactured in North America using only originating materials. This applies to agricultural products, minerals, and goods made entirely from originating inputs.

Automotive Rules: The Most Stringent

USMCA’s automotive rules of origin are the most demanding of any trade agreement in the world. Passenger vehicles must meet 75% RVC (up from 62.5% under NAFTA). Core parts like engines, transmissions, and body/chassis must also individually meet 75% RVC. Additionally, 70% of the steel and aluminum used must be sourced from North America, and 40-45% of the vehicle content must be produced by workers earning at least $16/hour (the Labor Value Content requirement).

How to Certify Origin Under USMCA

USMCA replaced the formal Certificate of Origin form used under NAFTA with a more flexible certification system. Any of three parties can certify origin: the importer, the exporter, or the producer. The certification must include nine minimum data elements defined in Annex 5-A of the agreement, including the certifier’s identity, the goods description, the HTS code, the origin criterion, and a blanket period if applicable.

Certifications can cover a single shipment or a blanket period of up to 12 months for identical goods. The importer must have the certification in their possession at the time of entry or within a reasonable period after. CBP can request verification at any time within five years of entry.

Common Pitfalls

• Assuming that assembly in Mexico = USMCA origin (many products require tariff shift or RVC)
• Using the wrong RVC calculation method (Transaction Value vs. Net Cost)
• Not tracking non-originating materials through the supply chain
• Missing the blanket certification period and importing without valid certification
• Claiming preference on goods that use Chinese inputs exceeding the de minimis threshold (typically 10% of transaction value)

How Camtom Streamlines USMCA Compliance

Camtom’s classification engine automatically identifies whether USMCA preference is available for your HTS code and origin country. The system flags the applicable rule of origin (tariff shift, RVC, or wholly obtained), calculates preliminary RVC based on your inputs, and generates the certification data elements required under Annex 5-A.
