Section 338 authorizes the President to offset the full burden, not merely mirror the offending product. Tariffs on Canadian dairy, alcohol, or autos alone would not equal the damage caused by Canada’s measures, while autos and auto parts are already covered by a separate Section 232 regime. The proclamations therefore extend to additional Canadian goods. The goal is a comparable burden until Ottawa lifts its burden on American producers. This is reciprocal trade enforcement, not economic aggression.
