Industry Snapshot
Key metrics for the urethane and other foam product manufacturing industry.
Industry Definition & Overview
Urethane and Other Foam Product (except Polystyrene) Manufacturing (NAICS 326150) encompasses establishments primarily engaged in manufacturing foam products from polyurethane, polyethylene, EVA, melamine, and other non-polystyrene materials. Products include flexible polyurethane foam for furniture cushioning and mattresses, rigid polyurethane and polyisocyanurate foam board for building insulation, spray polyurethane foam systems, automotive seating foam, cross-linked polyethylene foam for protective packaging, and carpet cushion. According to the U.S. Census Bureau[5], this classification covers both pour-in-place and slab foam production operations serving furniture, bedding, automotive, construction, and packaging end markets.
Production methods include continuous slab stock pouring for flexible foam bun production, high-pressure and low-pressure dispensing systems for molded automotive and furniture foam, rigid board lamination for insulation panels, spray foam application systems, and cross-linked foam extrusion. The Bureau of Labor Statistics[6] identifies core production roles including pour operators managing polyol-isocyanate mix ratios and reaction profiles, fabrication technicians cutting and shaping foam to specifications, mold operators producing contoured automotive and furniture parts, and quality inspectors testing density, compression, and tensile properties.
Per the SBA Office of Advocacy[7], polyurethane foam producers operate across highly diverse end markets that buffer against single-sector downturns. Furniture and bedding demand tracks consumer spending and housing turnover. Construction insulation demand follows commercial and residential building activity. Automotive foam volumes correlate with vehicle production schedules and seating content per vehicle.

Frequently Asked Questions
Common questions about this industry.
What types of businesses are classified under NAICS 326150?
NAICS 326150 covers manufacturers producing foam products from polyurethane, polyethylene, EVA, melamine, and other non-polystyrene materials. Products include furniture cushioning foam, mattress foam, automotive seating foam, rigid insulation board, spray foam systems, carpet cushion, and cross-linked polyethylene packaging foam. Per the U.S. Census Bureau[11], the classification excludes polystyrene foam products, which fall under 326140.
How is the urethane foam industry structured?
The industry divides into slab stock producers pouring large foam buns for furniture and bedding fabrication, molded foam producers serving automotive and specialty applications, rigid foam board manufacturers supplying construction insulation, and spray foam system suppliers serving building contractors. Slab producers compete on density consistency and fabrication capabilities. Molded producers differentiate through tooling expertise and just-in-time delivery to automotive assembly plants.
What is the SBA size standard for NAICS 326150?
