This message is to inform the trade community of the release of the USMCA Interim Implementing Instructions.


These Interim Implementing Instructions are informational and provide early guidance on the new requirements under the USMCA, including information on claiming USMCA preferential treatment for goods.


The Final Implementing Instructions will be released prior to the date the USMCA enters into force and will provide the Trade and Field with additional details on the USMCA entry, compliance, and other requirements.


To support the USMCA implementation, Title 19, Code of Federal Regulations 182 (19 CFR 182) is being developed to include the USMCA Uniform Regulations, USMCA Domestic Regulations, and Appendix. Further, the Harmonized Tariff Schedule of the United States is to be amended to include General Note 11 with information on the USMCA rules of origin. As such, these Interim Implementing Instructions are subject to change pending the issuance of GN11 and 19 CFR 182 regulations.


Until the USMCA enters into force, the North American Free Trade Agreement (NAFTA) requirements remains in effect.
