There are currently no specific tariffs or quotas on quartz products.
However, the International Trade Commission initiated a Section 201 investigation on December 1, 2025, into whether these items are being imported in sufficient quantities to be a substantial cause or threat of serious injury to a domestic industry. Comments from interested parties are due by December 22, 2025.
QSP consists of slabs and other surfaces created from a mixture of materials that includes predominately silica (e.g., quartz, quartz powder, cristobalite, glass powder) as well as a resin binder (e.g., an unsaturated polyester). The investigation only includes products where the silica content is greater than any other single material by actual weight.
QSP is typically sold as rectangular slabs with a total surface area of approximately 45 to 60 square feet and a nominal thickness of one, two, or three centimeters. However, the investigation covers (1) QSP of all other sizes, thicknesses, and shapes and (2) surfaces other than slabs such as countertops, backsplashes, vanity tops, bar tops, work tops, tabletops, flooring, wall facing, shower surrounds, fireplace surrounds, mantels, and tiles.
The investigation covers QSP regardless of whether or not it is (1) polished, cut, fabricated, cured, edged, finished, thermoformed, or packaged and (2) imported attached to, or in conjunction with, non-subject merchandise such as sinks, sink bowls, vanities, cabinets, and furniture.
Subject QSP includes material that has been finished, packaged, or otherwise fabricated in a third country, including by cutting, polishing, curing, edging, thermoforming, attaching to or packaging with another product, or any other finishing, packaging, or fabrication that would not otherwise remove it from the scope if performed in the country of manufacture of the QSP.
QSP covered by the investigation is provided for HTSUS subheadings 6810.99.0020, 6810.99.0040, and 7020.00.6000.
The investigation does not cover quarried stone surface products such as granite, marble, soapstone, or quartzite.
