On April 24, 2020, the United States publicly announced that the Canada-United States- Mexico Agreement (CUSMA) (or USMCA under US terminology) will enter into effect to replace the North America Free Trade Agreement (NAFTA) on July 1, 2020.  It is time to get prepared and ensure that your businesses processes in place to comply with the new CUSMA rules.

It is important to note that Canada, United States and Mexico must now negotiate and publish Uniform Regulations relating to customs matters.  There will be additional  regulatory changes announcements over the next weeks that may require further adjustments to business practices.  That being said, do not leave your consideration of the necessary changes and steps that should be taken until the last minute.

What you might need to do you prepare for CUSMA?

Canadian businesses, exporters, importers, etc. have a little over 2 months to get ready and the clock is ticking.  What a company must do will depend upon the particular circumstances of the company.  We cannot list all the steps to get ready.  However, we set out a number of suggestions below:

  1. Inform your customs broker that they should update their customs tariff codes to be used with respect to imports from United States (UST) and Mexico (MXT) and to stop using the MUST tariff code.  See Certification of Origin Requirements under CUSMA not the same as NAFTA;
  2. Contact exporters from Mexico and the United States to ensure that the goods that they have reviewed the new rules of origin and have applied the NAFTA 2.0 rules of origin to the goods and have verified that preferential treatment is appropriate. Review the rules of origin to determine whether the test for preferential treatment (duty free treatment or reduced customs duties) under CUSMA have changed;
  3. Contact exporters from Mexico and the United States and ask that they update their computerized systems to ensure that all invoices contain the appropriate Certification of Origin (the blanket NAFTA Certificates of Origin cannot be used).  See – Certification of Origin Requirements under CUSMA not the same as NAFTA;
  4. Update your computerized systems to ensure that all invoices contain the appropriate Certification of Origin (the blanket NAFTA Certificates of Origin cannot be used);
  5. Seek updated advanced rulings relating to origin issues – Update: When CUSMA enters into effect, NAFTA advance rulings are no longer valid;
  6. Review the rules of origin (some rules are very complex) to determine whether goods that you export that were subject to customs duties under NAFTA are no longer subject to customs duties under CUSMA;
    1. Ensure you start with the right tariff classification for the good – this online tool might be helpful;
    2. Review the rule of origin for that good to determine if the rule is a tariff shift rule or a regional value content rule or another rule;
    3. Review your Bill of Materials and update the Bill of Materials if the components or ingredients have changed;
    4. List the origin of each item in the Bill of Materials;
    5. List the tariff classification number for each item that was not manufactured in Canada;
    6. If you must a apply a tariff shift rule of origin, ensure that the tariff shift has occurred for each item in the Bill of Materials; and
    7. If you must apply a regional value content rule, perform the calculations to determine if the rule of origin is satisfied;
  7. If you will be importing or exporting vehicles or parts, review Are you ready for the new CUSMA/USMCA/NAFTA 2.0 Auto Rules of Origin?;
  8. Determine whether the changes to transshipment rules affect your imports into Canada see Article 4.18 of Chapter 4 of the CUSMA and the associated documentation requirements are contained in Article 5.4(3) of Chapter 5 of the CUSMA;
  9. If you import “specially defined mixtures”, determine if the changes to the definition affect your imports and/or exports – See Customs Notice 20-13;
  10. Importers of record in Canada might be entitled to duty savings as the low value shipment thresholds increase – The CBSA announced new LVS threshold for use after CUSMA implementation;
  11. Direct selling companies and other e-tailers (stores that sell over the internet) should update their computerized records to reflect that the online shopping duty-free threshold for Canadian consumers buying U.S. origin goods will be increased from $20 to $150 when the goods was shipped by mail or courier; and
  12. Importers of U.S. dairy, poultry and egg products should watch Global Affairs website for information about applying for new quota – more U.S. dairy, poultry and eggs will be entitled to enter Canada and you will need quota to take advantage of this benefit.
