What changed

The USITC made an affirmative injury determination in Investigation No. TA-201-79, finding that quartz surface products are being imported into the United States in increased quantities that are a substantial cause of serious injury to domestic producers. Chair Amy A. Karpel and Commissioner Jason E. Kearns voted in the affirmative while Commissioner David S. Johanson dissented. The Commission also made findings under FTA implementing statutes, determining that imports from Canada, Mexico, and other FTA partners do not individually account for a substantial share of total imports or contribute importantly to the serious injury.

The remedy phase will begin with a public hearing on April 14, 2026. The Commission will submit its report with injury determination, remedy recommendations, and additional findings to the President by May 18, 2026. However, the President—not the Commission—will make the final decision on whether to provide relief and what form such relief will take, including with respect to imports from FTA countries. Domestic manufacturers should prepare testimony for the April 14 remedy hearing. Importers and investors should monitor developments as any presidential action could result in tariffs or quotas affecting quartz surface product imports.

Contact: Jennifer Andberg, 202-205-1819 USITC Determines Increased Imports of Quartz Surface Products Injure U.S. Industry

The U.S. International Trade Commission (Commission or USITC) today determined that quartz surface products are being imported into the United States in such increased quantities as to be a substantial cause of serious injury to the domestic industry producing products like or directly competitive with the imported products.

The determination was made in the context of an investigation initiated on November 17, 2025, under section 202 of the Trade Act of 1974 (19 U.S.C. § 2252) in response to a petition filed by

Quartz Manufacturing Alliance of America (QMAA). Information about this investigation and global safeguard investigations is available in the fact sheet.

The Commission’s determination resulted from a 2-1 vote. Chair Amy A. Karpel and Commissioner Jason E. Kearns voted in the affirmative. Commissioner David S. Johanson voted in the negative.

As a result of today’s vote, the Commission will proceed to the remedy phase of the investigation. The Commission will hold a public hearing on remedy on April 14, 2026. The Commission will submit its report containing its injury determination, remedy recommendations, certain additional findings, and the basis for them to the President by May 18, 2026.

When the Commission makes an affirmative injury determination in a global safeguard investigation, it is required to make certain additional findings under the statutes implementing certain free trade agreements (FTAs).

Pursuant to these statutes, the Commission finds that imports of quartz surface products from neither Canada nor Mexico account for a substantial share of total imports or contribute importantly to the serious injury caused by imports. It also finds that imports of quartz surface products from each other FTA partner country, individually, are not a substantial cause of serious injury or threat thereof.

These findings will be forwarded to the President as part of the Commission’s report.

The President, not the Commission, will make the final decision concerning whether to provide relief to the U.S. industry and the kind of relief to provide, including with respect to imports from FTA countries.

A public report concerning this investigation will be available after the Commission submits its findings and recommendations to the President; when available, it may be accessed on the USITC website at the Commission’s Publications Library.
