NAICS 326299

Overview

The North American Industry Classification System is the federal standard for organizing establishments so statistical agencies can collect, analyze, and publish data on the U.S. economy. Developed under OMB with Canada and Mexico, it replaced SIC in 1997 and is maintained on the 2022 vintage for current economic programs. ¹
326299 covers establishments primarily engaged in manufacturing rubber products from natural or synthetic rubber, except tires; hoses and belting; and molded, extruded, or lathe‑cut rubber goods for mechanical applications. It functions as the “all other” category within Other Rubber Product Manufacturing and is used by agencies to classify output for economic statistics. ²

What this NAICS covers

• Rubber tubing manufacturing (non‑hose, non‑belting). ²
• Rubber floor mats and stair treads production. ²
• Inflatable rubber boats and life rafts manufacturing. ²
• Rubber erasers and comparable rubber office supplies. ²
• Other rubber products not elsewhere classified in 326291, 326220, or tire manufacturing (326211, 326212). ²
