NAICS 212313

Overview

The North American Industry Classification System (NAICS) is the federal standard for grouping business establishments to support collection and publication of U.S. economic statistics. Established by the Office of Management and Budget, NAICS replaced SIC in 1997 and is updated on a five-year cycle to maintain comparability across the U.S., Canada, and Mexico. The current vintage is 2022, and agencies phase in updates per official implementation timelines. ¹

NAICS 212313 covers establishments primarily engaged in developing the mine site and mining or quarrying crushed and broken granite, including related rocks such as gneiss, syenite, and diorite. It also includes preparation plants that beneficiate granite using mechanical processes (e.g., crushing, grinding, pulverizing, screening, sizing). Quarrying for dimension stone is classified under NAICS 212311, and other crushed stone types (e.g., limestone, miscellaneous) are separately coded under NAICS 212312 or NAICS 212319. ²

What this NAICS covers

• Developing mine sites for crushed and broken granite operations. ²
• Quarrying and extracting granite and related rocks (e.g., gneiss, syenite, diorite) for aggregate. ²
• Beneficiating granite through crushing, grinding, pulverizing, and related mechanical processing. ²
• Screening, washing, and sizing stone in preparation plants associated with quarry operations. ²
• Producing crushed granite for use as construction aggregate and related applications within mining scope (not manufacturing). ²
• Excluding dimension stone activities, which are classified under NAICS 212311. ²
• Excluding crushed limestone or other non‑granite stone, which fall under NAICS 212312 or NAICS 212319. ²

Frequently asked questions

• What activities define NAICS 212313? Establishments covered by NAICS 212313 develop granite mine sites, extract crushed and broken granite (and related rocks like gneiss, syenite, diorite), and operate preparation plants that mechanically process the stone through crushing, grinding, screening, and sizing. These are mining activities rather than manufacturing. ²

• Which rocks are included under “granite” in this code? The scope explicitly includes geologically related intrusive or metamorphic rocks—such as gneiss, syenite, and diorite—when produced as crushed and broken stone for aggregate. Dimension stone activities remain outside this code and are classified under NAICS 212311. ²

• How does NAICS 212313 differ from NAICS 212311 and NAICS 212319? 212313 covers crushed and broken granite; 212311 covers dimension stone quarrying; 212319 captures crushed and broken stone other than limestone or granite. Select the code based on material type and whether the output is dimension stone or aggregate. ²

• What PSC codes commonly appear with granite aggregate purchases? Construction material procurements for bulk mineral aggregates often use PSC 5610 (Mineral Construction Materials, Bulk). Some masonry components could appear under PSC 5620 (Building Glass, Tile, Brick, and Block), depending on the exact item purchased and specification language. ⁵

• What is the current NAICS vintage and when is it revised? The current NAICS vintage is 2022. NAICS is reviewed and revised every five years (years ending in 2 and 7) under OMB’s Economic Classification Policy Committee, with federal statistical programs phasing in the 2022 basis according to the Census implementation timeline. ³
