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.

Aug 21, 2026 - Trump Imposes TRQ on Imports

• 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.
• A proposed US Trade Representative (USTR) action could impose a 25% tariff on most goods imported from Brazil, including granite, marble, and slate, while exempting quartzite, Stone World reported in June. While no tariff has been imposed yet, if implemented it would impact 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. The tariff would increase raw material costs, disrupt 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. The proposal is currently undergoing a public comment and hearing process, and the final tariff rate and exemption list could change before any duties take effect, per Stone World.
• Brazil’s exports of natural stone jumped by 20% between January and October to $1.24 billion, despite steep US tariffs of up to 50% on granite, marble, and soapstone, according to the Brazilian Natural Stone Association. Still, the levies caused sharp declines in shipments of materials most relevant to US stone product manufacturers, with granite exports falling 14.7%, marble down 9.8%, and soapstone plunging 54.6%. Only quartzite, which is seeing significant growth, especially for kitchen and bathroom countertops, is exempt from US tariffs. Lower volumes of tariff‑impacted Brazilian stone ease competitive pressure on US producers of cut stone, while makers of stone products that rely on Brazilian exports face tighter supplies and higher costs, especially for granite and marble. While tariff turmoil continues, US producers should look to diversify sourcing away from Brazil and strengthen their domestic supply chains.
• Producer prices for cut stone and stone product manufacturers rose 4.7% in July compared to a year ago, after rising 2.8% in the previous July-to-July 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 3.1% year over year in June, while in July the average industry wage rose 2.7% YoY to $29.60 per hour, $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 18 workers, and generates about $3.9 million in annual revenue.

• According to the Census, the cut stone and stone product manufacturing industry comprises about 2,031companies that employ about 36,565 workers and generate $8 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.
