What the list is
Section 338 of the U.S. Tariff Act of 1930 lets the President add up to 50% on goods from a country found to discriminate against U.S. trade. Three proclamations in July 2026 targeted Canada over vehicle tariffs, provincial alcohol bans and dairy supply management. The duty took effect on August 22, 2026 on 554 lines. On September 15 the U.S. added 122 lines and removed 10, for 666. A proclamation on October 23 adds 100 lines and removes 22 for goods entered from 12:01 a.m. Eastern on October 30, 2026, for 744. The search above shows the list from October 30.
