The White House says it will impose a sweeping 100% tariff on Chinese goods, raising major stakes for trade and supply chains.

What Happened

On October 10, 2025, the administration announced it would impose a 100% tariff on all Chinese imports beginning November 1, in addition to new export controls on “critical software.” The move comes on top of existing duties and signals a major escalation in U.S.–China trade policy.

Markets responded sharply: the S&P 500 fell about 2.71% and the Nasdaq dropped 3.56% during the trading day following the announcement.

Why It Matters

– Importers, manufacturers, and retailers must rapidly recalculate costs, contracts, and sourcing strategies.
– The tariff could ripple through global supply chains, especially for electronics, machinery, and consumer goods.
– Enforcement, exemptions, and legal challenges will raise compliance risk and burden Customs, USTR, and trade counsel.
