The Rubicon moment
Section *** is unlike any other US tariff tool. It lets the president impose duties of up to ** per cent on any country he finds discriminates against US commerce. There is no investigation. There is no hearing. He acts by proclamation alone. Trade lawyers have described it as the “nuclear option”. Covington & Burling attorneys John Veroneau and Catherine Gibson found no public record of Section *** being invoked since ****, making its **** use the statute**;s first modern invocation. Cato Institute economist Scott Lincicome summed up the shock: “We crossed the Rubicon. The invocation of *** is the nuclear option for Trump tariffs.” The distinction matters. Section *** needs a US Trade Representative (USTR) investigation. Section *** needs a national-security finding. International Emergency Economic Powers Act (IEEPA) emergency tariffs were struck down by the Supreme Court in early ****. Section *** does not require those procedures and applies notwithstanding USMCA tariff preferences.
The landed-cost math
For apparel buyers, the financial impact is immediate. Until now, garments meeting USMCA rules of origin entered the United States duty-free. Under Section ***, those same products will face an additional ** per cent tariff from August **, fundamentally increasing their landed cost. As illustrated in Chart *, a Canadian apparel shipment valued at $*** free on board (FOB) will incur $** in additional duty, raising its landed cost to $*** before freight, insurance, and other import-related expenses. The implications extend beyond apparel. The proclamation annexes explicitly list clothing among the covered products, alongside furniture, wine, cement, and hockey equipment. This confirms that Canadian textile and apparel exports qualifying for duty-free treatment under USMCA are now subject to the new tariff, significantly altering sourcing economics for US importers.
