Tariffs on Canadian and Mexican Imports
February 1, 2025
Executive Orders 14193 and 14194 imposed 25% tariffs on imports from Canada and Mexico using IEEPA emergency authority, citing border security and drug trafficking concerns. The orders raised significant questions about whether IEEPA was designed for trade disputes with neighboring allies and whether border issues constitute the type of economic emergency the statute contemplates. The tariffs strained both constitutional trade authority and existing treaty relationships under USMCA.

Steelman Analysis
IEEPA provides broad emergency authority and border security threats from fentanyl trafficking and illegal immigration constitute genuine emergencies. Economic leverage through tariffs can pressure allies to strengthen their own border enforcement. The President has significant foreign affairs authority to use economic tools for national security objectives.
