How to Calculate Rules of Origin
What is Rules of Origin?
The Rules of Origin Calculator determines whether a product qualifies for preferential tariff treatment under a free trade agreement (like USMCA or CPTPP) by evaluating regional value content, tariff shift, and processing requirements.
Formula
Regional Value Content (RVC) = ((Transaction Value - Non-Originating Materials) / Transaction Value) × 100%
- TV
- Transaction Value ($) — Price actually paid or payable for the good
- VNM
- Value of Non-Originating Materials ($) — Cost of materials that do not originate in the FTA region
- NC
- Net Cost ($) — Total cost minus sales promotion, royalties, and shipping/packing
- RVC
- Regional Value Content (%) — Percentage of value originating within the FTA region
Step-by-Step Guide
- 1Identify the applicable FTA and the specific rule of origin for your product HTS code
- 2Calculate Regional Value Content using either the transaction value or net cost method
- 3Check whether the product meets the required tariff shift (change in HTS chapter/heading)
- 4Verify any product-specific rules such as minimum processing or technical requirements
Worked Examples
Input
Auto part under USMCA, transaction value $500, non-originating materials $200
Result
RVC = ($500 - $200) / $500 × 100 = 60%. USMCA auto parts require 75% RVC — does NOT qualify
Input
Textile under CPTPP, yarn-forward rule, yarn spun in Vietnam, woven and cut in Vietnam
Result
Meets yarn-forward rule — qualifies for CPTPP preferential rate
Common Mistakes to Avoid
- ✕Using transaction value method when net cost method would yield a better RVC
- ✕Not tracking origin of all inputs — even minor components can disqualify the product
- ✕Assuming assembly alone qualifies as sufficient transformation
Frequently Asked Questions
What is the USMCA RVC requirement for automobiles?
USMCA requires 75% regional value content for passenger vehicles and light trucks (phased in from the original NAFTA 62.5%), with additional requirements for core parts, steel, and aluminum sourcing.
What happens if a product fails the origin test?
The product is imported at the MFN (most-favored-nation) duty rate instead of the preferential FTA rate, which can mean significantly higher duties.
