On July 31, 2026, President Trump issued proclamation “To Facilitate Positive Adjustment to Competition From Imports of Quartz Surface Products,” introducing a tariff-rate quota (“TRQ”) that will go into effect on August 15, 2026 on imports of certain quartz surface products under Section 203 of the Trade Act. The action follows a recommendation from the International Trade Commission in May 2026, which found that increased import volumes of quartz are harming the domestic quartz industry.
