Episode notes
Alternate Tariff Authorities Require Process
- Other statutory routes like Section 232 (national security) and Section 301 (unfair trade) remain available but require investigations and public processes.
- These pathways limit immediate, unconstrained presidential tariff actions compared with IEPA.
Section 338 Is Unclear And Litigious
- Section 338 exists as an older, less-procedural tariff authority but is untested in modern courts and requires proving discrimination against U.S. exports.
- Its legal ambiguity makes it a risky, litigious option for broad tariffs.
Tariffs Create Investment Uncertainty
- Tariffs have been used largely as a revenue source and create uncertainty that deters large manufacturing investments.
- Firms delay multibillion-dollar decisions while awaiting clarity on which tariff authority will govern imports and inputs.
