US CBP Provides Updated Guidance on Canada and Mexico Tariffs

White House Delays Some Canada and Mexico Tariffs

On March 6, 2025, the White House issued two Executive Orders (EO) delaying the 25 percent tariff on some products of Canada and Mexico effective March 7, 2025, at 12:01 a.m. Eastern Time. The EO’s do not specify an ending date to this action. Products of Canada and Mexico that qualify for the United States Mexico Canada Agreement (USMCA) including Chapter 98 and 99 will not be subject to the 25 percent additional tariffs as directed in EO 14193 or EO 14194. Lowers the additional tariff for potash from 25 percent to 10 percent for those products that do not qualify for USMCA.

Additionally, U.S. Customs and Border Protection (CBP) provided additional guidance in Cargo Systems Messaging Service (CSMS) CSMS # 64336037 Imports from Canada and CSMS # 64335789 Imports from Mexico (see links below). The new classifications to be filed at the time of entry include:

Canada
9903.01.14 – Articles of Canada eligible for USMCA
9903.01.15 – Potash, per nine specific HTS outlined in the CSMS message

Mexico
9903.01.04 – Articles of Mexico eligible for USMCA
9903.01.05 – Potash, per the nine specific HTS outlined in the CSMS message
For all other Canadian and Mexican imported products that do not meet the eligibility requirements of USMCA General Note 11 of the Harmonized Tariff Schedule of the United States (HTSUS), the 25 percent additional tariff will apply as of March 4, 2025. The import rates for Canadian energy products will remain at 10 percent.
