Cut Stone & Stone Product Manufacturers

The 2,031 stone products manufacturers in the US cut, shape and finish granite, marble, limestone, slate, and other types of stone for building projects and other uses. Firms may also work with composites, such as engineered stone or solid surface products. Applications for cut stone products include countertops, floors, and walls. Stone fabricators may have in-house staff dedicated to installation, rely on subcontractors, or use a combination.

Competition from Alternatives

Natural and manufactured stone competes with a variety of other materials, depending on the application.

Dependence on Imports

Stone fabricators are highly dependent on foreign suppliers for dimensional stone, with imports accounting for 83% of the US market, according to the US Geological Survey.

Oct 21, 2026 - QMAA Defends Tariffs on Imported Quartz

• US quartz manufacturers are fighting a legal challenge to tariffs on imported quartz surfaces that took effect in August, according to a September announcement from the Quartz Manufacturing Alliance of America (QMAA). The tariffs followed a federal investigation that found surging imports had harmed domestic producers. Quartz slab imports increased 78.3% between 2020 and 2024, while US production declined 17.2% over the past five years, despite growing demand. Domestic manufacturers argue that the tariffs will encourage US production and investment, while importers are seeking to overturn them. For cut stone and stone product manufacturers, particularly countertop fabricators, the tariffs could raise the cost of imported quartz slabs and limit sourcing options, while their domestic suppliers could benefit from reduced foreign competition. Fabricators of quartz countertops and other quartz products used in residential construction may need to adjust purchasing strategies and pricing to protect margins.
• President Trump has imposed a four-year tariff-rate quota (TRQ) on imported quartz surface products effective August 15, 2026, with imports within the annual quota subject to a 25% tariff and higher-volume imports facing a 50% duty, Stone World reports. Trump's action follows a US International Trade Commission finding that increased imports seriously injured the US quartz surface product industry. The TRQ is intended to support domestic quartz manufacturers by limiting lower-priced imports from major suppliers, while Canada, Mexico, and several other countries are exempt. For US cut stone and stone products manufacturers, particularly producers of engineered quartz surfaces, the tariffs could improve competitiveness, encourage domestic investment, and strengthen local production. However, higher import costs may reduce product availability and increase prices for fabricators, contractors and consumers, potentially affecting demand for countertops and other stone products used in residential and commercial construction.
• In July, the Office of the US Trade Representative (USTR) imposed an additional 25% tariff on most goods imported from Brazil, including granite, marble, and slate. The new tariff impacts cut stone and stone product manufacturers that rely on Brazilian materials as Brazil supplied nearly one-quarter of US natural stone import volume and about 41% of import value in 2025. It increases raw material costs, disrupts supply chains, and raise prices for products made with Brazilian granite, marble, and slate. Manufacturers may need to seek alternative suppliers or pass higher costs on to customers.
• Producer prices for cut stone and stone product manufacturers rose 8% in September compared to a year ago, after rising 3.6% in the previous September-to-September annual comparison, according to the latest US Bureau of Labor Statistics data. The industry producer price is at a record high following a prolonged steady climb fueled by a combination of higher input costs, energy inflation, and strong construction demand. Employment by lime, gypsum, and other nonmetallic mineral product manufacturers grew 4.2% year over year in August, while in September the average industry wage rose 1.5% YoY to $29.52 per hour, just $0.10 shy of its record high in June, BLS data show.

Industry size & Structure

The average stone products manufacturer operates out of a single location, employs 17 workers, and generates about $4 million in annual revenue.

• According to the Census Bureau, the cut stone and stone product manufacturing industry comprises about 2,031companies that employ about 33,845 workers and generate $8.1 billion annually.
• According to the industry group the Natural Stone Institute (NSI), there are 9,689 dimension stone firms and 2,223 crushed stone firms in the US, employing about 86,000 and 42,000 workers, respectively. An NSI survey found that automated shops employ an average of 38 workers, while manual shops, which tend to be smaller operators, employ an average of 10 workers. The average sales volume was between $2 million and $3 million.
• The industry is fragmented; the top 50 companies account for about a third of industry revenue.
• Large, vertically-integrated firms, such as Coldspring Granite, extract, cut, and finish stone products. Most firms are small and serve a local market.
