Federal Government News
Presidential Proclamation: US Import Ban on Select Canadian Products in Ongoing Auto Trade Dispute
On September 8, 2026, President Trump issued a proclamation barring the importation of certain Canadian products, effective September 29, 2026. The action follows a series of tariff escalations prompted by Canada's motor vehicle tariff regime, with the ban and 50% duties targeting a specific list of Canadian goods. US Customs and Border Protection and relevant agencies have been authorized to enforce the ban and update the Harmonized Tariff Schedule. This development follows prior temporary tariff suspensions and renewed commitments from Canadian officials that were deemed unfulfilled by the US executive branch.

White House Response to Canada’s Retaliatory Tariffs: Section 338 Actions and Procurement Restrictions
President Trump signed five proclamations on September 8, 2026, invoking Section 338 of the Tariff Act of 1930 to respond to Canada’s retaliatory tariffs on $20 billion worth of US exports, such as steel, dairy, and agricultural machinery. The proclamations implement new import bans on Canadian-origin alcoholic beverages, dairy products, and other goods previously subject to 50% tariffs, while altering the tariff schedule to remove some products and add all-terrain vehicles and expanded dairy categories. The restrictions take effect between September 15–29 and supplement existing Section 232 tariffs. US agencies have also been directed to remove Canadian-origin products from federal procurement, with the White House citing incentives to reshore manufacturing investments.

EPA Announces Contractor and Subcontractor Access to Confidential Business Information under Air, Marine, and AIM Rules
The US Environmental Protection Agency (EPA) Office of Enforcement and Compliance Assurance issued a notice of intent on September 9, 2026, to allow Eastern Research Group, Inc., along with subcontractors, to access confidential business information (CBI) submitted under the Clean Air Act, Act to Prevent Pollution from Ships, and American Innovation and Manufacturing Act. Contractors will have access to confidential enforcement data for inspection, audits, and regulatory support, in accordance with EPA security procedures and subject to nondisclosure agreements. Access for enforcement support under contract 68HERL26A0022 is scheduled to begin September 15, 2026, and last through June 26, 2031.

PHMSA Preempts California Reusability Mandate for Propane Cylinders
On September 10, 2026, the Pipeline and Hazardous Materials Safety Administration issued an administrative ruling preempting California’s Public Resources Code, Sections 42395-42395.2, which mandates that only reusable or refillable propane cylinders may be sold in California after January 1, 2028. The agency determined that California’s law imposes design and manufacturing requirements not substantively the same as federal DOT-39 specification cylinder rules, and that the state mandate creates a regulatory obstacle to nationwide hazardous materials transportation uniformity. PHMSA’s decision becomes final unless a petition for reconsideration or judicial review is filed. The decision references input from manufacturers, state agencies, and trade stakeholders.

USITC: Final Phase of Countervailing Duty and Antidumping Investigations on Citric Acid and Certain Citrate Salts from Canada and India
The US International Trade Commission announced on September 11, 2026, the scheduling of the final phase in antidumping and countervailing duty investigations on citric acid and certain citrate salts from Canada, India, and China. For Canadian imports, Commerce Department preliminary findings indicate no less-than-fair-value sales, but a finding of subsidy provision. The Commission's staff report will be available December 28, 2026, with a public hearing set for January 12, 2027. Written submissions are due prior to the hearing. These proceedings address imports classified under HTS subheadings 2918.14.00, 2918.15.10, 2918.15.50, and 3824.99.93 and involve participation from major agricultural producers such as Archer-Daniels-Midland and Cargill.
