Mondaq's analysis (July 29) provides the most useful structural map of where US tariffs now stand. The current architecture has three layers: Section 301 forced-labor duties (10–12.5%, effective July 24, covering 60 economies); Section 232 national security duties on steel, aluminum, autos, and semiconductors (sector-specific, pre-existing); and active Section 301 investigations into EU digital service tax retaliation, Brazilian imports (25% announced), and a new Canadian 50% tariff on dairy, auto, and alcohol under Section 338 — first use of Section 338 in US history. Mondaq describes this as the administration "demonstrating a rededication to US trade policy" through "continuous legal innovation" in the use of trade statutes. For GCs and trade counsel, the structural implication is that trade compliance now requires monitoring at minimum three statutory frameworks simultaneously, with enforcement postures that can shift — and add — within weeks.
