Industry Snapshot
Key metrics for the plumbing fixture fitting and trim manufacturing industry.
Industry Definition & Overview
Plumbing Fixture Fitting and Trim Manufacturing (NAICS 332913) encompasses establishments primarily engaged in manufacturing metal and plastics plumbing fixture fittings and trim, such as faucets, flush valves, shower heads, spigots, and supply line assemblies. Per the Census Bureau 2022 NAICS classification[5], this industry falls within Industry Group 3329 (Other Fabricated Metal Product Manufacturing). Products serve both residential and commercial construction markets. Demand correlates directly with new construction and renovation activity.
Manufacturers employ metalworking, casting, forging, stamping, and assembly operations to create components meeting plumbing codes and safety standards. Raw material inputs include brass, carbon steel, copper, zinc alloys, and thermoplastics. Production ranges from high-volume commodity faucets to specialized commercial fixtures. Water efficiency standards, particularly EPA WaterSense certification requirements, influence product design and engineering across the sector.
Industry participants range from large multinational corporations producing complete fixture lines to smaller specialized manufacturers focused on commercial or institutional product categories. Geographic distribution follows construction market density, with production facilities located near major population centers and distribution hubs. Import competition from Asia-Pacific producers, particularly in commodity product segments, pressures domestic manufacturers to differentiate through quality, compliance, and lead time advantages. Per Bureau of Labor Statistics data[6], fabricated metal product manufacturing supports over 1.5 million jobs nationally.
