On May 18, 2026, the United States International Trade Commission (ITC) delivered a report investigating the impact of imports of quartz surface products (QSP) under section 202 of the Trade Act of 1974. The ITC determined that imports of QSP are arriving in the United States in such increased quantities that they cause serious injury to the domestic industry producing like or directly competitive goods.
The ITC made negative findings regarding imports from Canada and Mexico, concluding that neither individually accounts for a substantial share of total imports or importantly contributes to the serious injury.
According to the ITC report, imports of QSP from Australia; the countries of the Dominican Republic-Central America-United States Free Trade Agreement (Costa Rica, the Dominican Republic, El Salvador, Guatemala, Honduras, and Nicaragua); as well as Colombia, Jordan, South Korea, Panama, Peru, and Singapore were also found not to be substantial causes of serious injury or threat thereof.
The ITC further established that the serious injury caused by imports does not result from the reduction or elimination of any duty under the United States-Israel Free Trade Agreement. It also stated that duty-free treatment under the Caribbean Basin Economic Recovery Act provisions or the Generalized System of Preferences is not responsible for the harm to the domestic industry producing quartz surface products.
Commissioners who voted affirmatively on the serious injury findings provided individual conclusions supporting recommendations to mitigate the injury. These recommendations aim to help the domestic industry adjust to increased competition from imports.
