Supreme Court Leaves China Section 301 Tariffs Standing

The Supreme Court declined to review the Federal Circuit’s decision upholding List 3 and 4A China Section 301 tariffs, ending the litigation without refunds for tariffs already paid. STR notes the decision may reinforce the administration’s confidence in modifying Section 301 tariffs in future proceedings. For legal and procurement teams, tariff volatility is now a strategic planning assumption. Contracts, sourcing and duty-mitigation strategies need to be designed around continuing China-tariff exposure.
