President imposes 4-year safeguard quota on quartz surface product imports
The safeguard tariff-rate quota applies to all quartz surface product imports beginning July 31 2026, with exclusions for Canada, Mexico and other specified partners.
Proclamation 11051, dated July 31, 2026, announces a safeguard measure for quartz surface products (QSP) classified under HTSUS subheadings 6810.99.0020, 6810.99.0040, and 7020.00.6000. The President determines that a tariff-rate quota is appropriate and feasible, to be in effect for a period of 4 years.
The quota will feature annual increases in the within-quota quantities and corresponding reductions in duty rates for goods entered within and in excess of those quantities during the second, third, and fourth years, as set forth in the proclamation's annex.
The measure excludes imports of QSP from Canada and Mexico, as well as from Australia, each CAFTA-DR country (Costa Rica, Dominican Republic, El Salvador, Guatemala, Honduras, Nicaragua), Colombia, Jordan, the Republic of Korea, Panama, Peru, Singapore, Israel, and products benefiting from the Caribbean Basin Initiative or Generalized System of Preferences.
Products from developing countries are exempt provided a single country's share of total QSP imports does not exceed 3 percent and the aggregate share of all such countries does not exceed 9 percent. If a WTO-member developing country's share exceeds either threshold, the exemption is withdrawn for that country.
The action relies on sections 202 and 203 of the Trade Act of 1974, the USMCA Implementation Act, and the relevant free-trade agreement implementation statutes cited in the proclamation. The ITC report dated May 18, 2026, and its supplemental report of July 2, 2026, form the factual basis for the determination.
