Mining, Quarrying, and Oil and Gas Extraction
Industry Definition & Overview
Crushed and Broken Granite Mining and Quarrying (NAICS 212313) encompasses establishments primarily engaged in mining or quarrying granite and crushing and breaking it for use as construction aggregate per the U.S. Census Bureau[5]. Activities include granite crushing, screening, sizing, and washing to produce graded aggregate products for road construction, concrete production, and other construction applications.
Granite accounts for roughly 15% of all U.S. crushed stone production, yielding an estimated 225 million tons annually based on total USGS[6] crushed stone output of 1.5 billion metric tons. Production concentrates in Southeastern states including Georgia, South Carolina, North Carolina, and Virginia, plus Texas and other regions where granite bedrock is accessible near population centers. Vulcan Materials Company and Martin Marietta Materials operate the largest granite quarrying portfolios among publicly traded aggregate producers. Granite aggregate commands a higher extraction cost than limestone due to the hardness of the material, requiring specialized crushing equipment and more energy-intensive processing. Transportation costs for crushed granite frequently equal or exceed the plant sale price, making quarry location relative to construction markets the primary competitive factor.
Per the SBA Table of Size Standards[7], the size standard is $30.5 million in average annual receipts. The Mine Safety and Health Administration[8] inspects surface granite quarries at least twice annually. OSHA[9] respirable crystalline silica standards apply to granite crushing and screening operations, with granite's high quartz content creating elevated dust hazards that require engineering controls including wet suppression systems and enclosed processing equipment.

Frequently Asked Questions
Common questions about this industry.
What is the NAICS code for granite quarrying?
NAICS 212313 covers crushed and broken granite mining and quarrying for aggregate production per the U.S. Census Bureau[5]. Dimension granite block quarrying is classified under NAICS 212311.
How much granite aggregate does the U.S. produce?
Granite accounts for roughly 15% of U.S. crushed stone production, yielding an estimated 225 million tons annually based on total USGS[6] output of 1.5 billion metric tons from domestic quarries.
What is the SBA size standard for granite quarrying?
Per the SBA size standard[7], the threshold is $30.5 million in average annual receipts, determining eligibility for federal small business contracting programs and SBA lending products for granite quarrying firms.
Why does granite cost more to quarry than limestone?
Granite's higher hardness requires specialized heavy-duty crushers and consumes more energy during processing compared to softer limestone per standard quarrying practice. Jaw crushers and cone crushers used for granite must withstand greater abrasion and impact forces, increasing both equipment cost and maintenance requirements.
Where are most U.S. granite quarries located?
Granite quarrying concentrates in Southeastern states including Georgia, South Carolina, North Carolina, and Virginia per USGS[6] production data. Texas and New England also contain major granite quarry operations serving regional construction markets.
Why are transportation costs critical for granite quarries?
Transportation costs for crushed granite frequently equal or exceed the plant sale price per industry cost data, making quarry proximity to construction markets the primary competitive advantage. This cost structure limits the effective delivery radius of most granite quarries to within 30-50 miles of the quarry site.
What safety hazards exist at granite quarries?
What is railroad ballast?
Railroad ballast is crushed stone placed beneath railroad tracks to provide drainage, distribute train loads, and maintain track alignment. Granite's hardness and durability make it a preferred ballast material per railroad engineering specifications, with Class I railroads consuming millions of tons annually for track construction and maintenance.
