[Expert Interpretation: Trump Invoking Section 122 Requires Declaring 'Imminent Significant Dollar Devaluation' or 'Severe Balance of Payments Deficit'] Jin10 News, February 21 – Jennifer Hillman, a professor of international trade law at Georgetown University, stated that if Trump intends to implement an additional 10% tariff under Section 122, he must declare that the U.S. is experiencing a 'severe and significant balance of payments deficit' or is facing a situation of 'imminent significant dollar devaluation.' Section 122 tariffs can only last for 150 days. Any extension would require congressional approval. Section 301 tariffs are long-term but require an investigation targeting specific countries, including holding hearings and allowing affected companies or countries to provide input. Hillman noted that the investigation must ultimately determine that the country has violated trade agreements or engaged in actions that exacerbate the U.S. trade burden.
