Section 201 safeguard on quartz surface products
Quartz safeguard tariff (Section 201)
What it is
A four-year safeguard on quartz surface products (engineered quartz slabs, countertops and similar surfaces), from Aug 15, 2026 through Aug 14, 2030. It is a tariff-rate quota: imports within the quarterly quota (3,251,606 square meters a quarter in the first year, unused amounts carried forward) pay 25% on top of the base rate; imports beyond it pay 50%. The rates fall each year: 23% and 49% from Aug 15, 2027, 21% and 48% from Aug 15, 2028, 19% and 47% from Aug 15, 2029. Products of Canada, Mexico, 13 free-trade partners, 100 listed developing countries and 17 Caribbean Basin beneficiaries are excluded and don't count against the quota.
Legal authority: Sections 201 and 203 of the Trade Act of 1974, as amended; Proclamation 11051 of Jul 31, 2026. Section 201 of the Trade Act of 1974 lets the President put temporary safeguard measures on imports that the U.S. International Trade Commission finds are a substantial cause of serious injury to a U.S. industry.
It reaches 3 listed tariff codes or code groups (a listed heading or subheading covers every code under it).

How it combines with other duties
Charged on top of the base rate of chapters 68 and 70; antidumping, countervailing and other duties and charges still apply (note 41(b)). Note 41 doesn't exempt goods from other chapter 99 duties, and the forced-labor tariff's exemption for goods under other programs (note 52(f)) lists only Section 232 headings, so both tariffs apply.
