1. Determine the good to be exported
2. Determine the proper H.S. tariff classification number of the good
3. Obtain a Bill of Materials for the good
4. Determine the country of origin of the materials. If the country of origin cannot be determined, or is uncertain, treat as non-originating
5. If all materials are NAFTA originating as being "wholly obtained or produced" in a NAFTA country, then proceed to step 8.
6. If materials originate in countries other than a NAFTA country, refer to the specific rule of origin in annex 401 for the "end" good to be exported. The rule will provide further instructions.
7. If the specific rule asks for a tariff shift - classify all non-originating material on the bill of materials.
   If the specific rule asks for a tariff shift and "Regional Value Content" (RVC) - classify all non-originating material on the bill of materials and calculate the RVC by using either the Transaction Value method or Net Cost method.
   If the specific rule asks for a "Regional Value Content" only - calculate the RVC by using either the Transaction Value method or Net Cost method.
8. If the goods qualify, prepare and sign a NAFTA Certificate of Origin. If the goods do not qualify, consider other options such as De Minimis, accumulation etc.

NOTE:
If using criterion C, obtain a producer's NAFTA certificate or letter from the producer certifying that the material/good qualifies as a NAFTA good. This will allow you to prepare a NAFTA certificate of origin on the good exported and is considered valid documentation to substantiate your NAFTA claim if audited by Customs.

These steps are to serve as a guide only. There are special provisions for electronic equipment, automotive and textiles that need to be taken into account when determining NAFTA eligibility.
