NAICS 332813

Overview

The North American Industry Classification System (NAICS) is the federal standard for classifying business establishments to support consistent collection, analysis, and publication of U.S. economic statistics. Established in 1997 under the Office of Management and Budget to replace SIC, NAICS was jointly developed by the U.S., Canada, and Mexico; the current vintage is 2022 and is being implemented across major programs. ¹

NAICS 332813 covers establishments primarily engaged in electroplating, plating, anodizing, coloring, buffing, polishing, cleaning, and sandblasting metals and metal products “for the trade.” If a plant both fabricates products and performs these finishing services, it is classified under the manufacturing NAICS of the product made, not in 332813. ²

• Classified in NAICS 332813: establishments primarily performing electroplating, plating, polishing, anodizing, coloring, cleaning, or sandblasting on a fee or contract basis. ²
• Not in NAICS 332813: establishments that both fabricate a product and perform finishing on that product; these are classified under the manufacturing NAICS for the product made. ²

Frequently asked questions

• What activities fall under NAICS 332813? NAICS 332813 covers job‑shop finishing services for metals: electroplating, plating, anodizing, coloring, buffing, polishing, cleaning, and sandblasting performed for others. The focus is finishing services rather than manufacturing the underlying product itself. ²

• How does NAICS 332813 differ from NAICS 332812? NAICS 332813 emphasizes electroplating, anodizing, polishing, and related finishing. NAICS 332812 covers metal coating and engraving (except jewelry and silverware) and allied services to manufacturers. They are adjacent within the same industry group but remain distinct. See also on G2X: NAICS 332812. ²

• Are firms that both fabricate products and plate them classified in NAICS 332813? No. If an establishment manufactures a product and also finishes that same product, classification follows the manufacturing NAICS for the product made. NAICS 332813 is intended for contract finishing shops serving other manufacturers. ²

• Does NAICS 332813 include sandblasting? Yes. The official 332813 description expressly includes cleaning and sandblasting of metals and metal products when performed for the trade on a fee or contract basis. ²

• Where can official statistics for NAICS 332813 be found? The 2022 Economic Census Manufacturing releases provide tables and datasets by NAICS industry, including 332813, via data.census.gov and downloadable files. Look for Sector 31–33 materials compiled on the Census data access page. ⁵
