NAICS 326150

Overview

The North American Industry Classification System (NAICS) is the federal standard for classifying business establishments to support the collection, analysis, and publication of U.S. economic statistics. Developed under the Office of Management and Budget and adopted in 1997 by the United States, Statistics Canada, and Mexico’s INEGI, it enables cross-country comparability. The current classification vintage is NAICS 2022. ³
NAICS 326150 covers establishments primarily engaged in manufacturing plastics foam products other than polystyrene; polystyrene foam products are classified in 326140. This industry sits within Plastics Product Manufacturing, where producers convert plastics resins into intermediate or final goods using molding and related processes. ²

What this NAICS covers

• Manufacturing of plastics foam products other than polystyrene, including urethane and other non-polystyrene foams. ²
• Production of non-polystyrene foam goods as intermediate or final products within the Plastics Product Manufacturing sector. ²
• Activities typical of Plastics Product Manufacturing, such as converting plastics resins via molding, extrusion, or casting to produce foam items. ²
• Processing of new or spent (recycled) plastics resins into foam products as part of sector 3261. ²
• Exclusion: establishments primarily manufacturing polystyrene foam products are classified in 326140. ²
• Exclusion: on-site building insulation installation is a construction activity classified in 238310 Drywall and Insulation Contractors, not in 326150. ⁶

Boundary notes

• Polystyrene vs. non-polystyrene: establishments manufacturing polystyrene foam belong in 326140; all other plastics foams belong in 326150. ²
• Non-foam plastics goods (e.g., bottles, laminates, profile shapes) fall in other Plastics Product Manufacturing industries such as 326160, 326130, or 32612; foam products remain within 326140 or 326150. ²
• Sector context: 326150 sits under industry group 3261 (Plastics Product Manufacturing), which converts plastics resins into products using molding and related processes. ²

Frequently asked questions

• What does NAICS 326150 include?
  NAICS 326150 includes establishments primarily engaged in manufacturing plastics foam products other than polystyrene. It is distinct from 326140, which covers polystyrene foam products. ²

• How is 326150 different from 326140?
  326150 covers non-polystyrene plastics foam (e.g., urethane and other polymers). 326140 is specifically for polystyrene foam products; Census lists this as the cross-reference boundary. ²

• Are foam installation services covered here?
  No. On-site installation of building insulation is a construction activity classified in 238310 Drywall and Insulation Contractors; 326150 is a manufacturing industry. ⁶

• Can products made from recycled resin be classified under 326150?
  Yes. Within industry group 3261, establishments convert new or spent (recycled) plastics resins into products; when the output is non-polystyrene foam, the industry is 326150. ²

• Which PSCs are often used when procuring foam plastics materials?
  Agencies commonly use material categories such as PSC 9330 (Plastics Fabricated Materials) and PSC 9390 (Miscellaneous Fabricated Nonmetallic Materials), depending on the specific item description. Always select the PSC that matches the product being procured. ⁴
