NAICS 326211

Overview

The North American Industry Classification System (NAICS) is the governmentwide standard used to classify business establishments for statistical purposes across federal programs. NAICS was developed under the Office of Management and Budget in cooperation with Canada and Mexico and replaced the SIC system in 1997. The current classification vintage is 2022, and federal statistical series continue migrating to that basis over time. ⁴
U.S. industry 326211 Tire Manufacturing (except Retreading) covers establishments primarily engaged in manufacturing new pneumatic tires and inner tubes from natural and synthetic rubber. Establishments may serve original equipment and replacement markets and typically perform processes such as compounding, building, curing (vulcanizing), and finishing. Retreading and rebuilding are excluded and classified under 326212. ²

What this NAICS covers

• Production of new pneumatic tires made from natural and synthetic rubber compounds for original equipment or replacement markets. ²
• Manufacturing of rubber inner tubes. ²
• Fabrication steps such as mixing, building, curing/vulcanizing, and finishing of new tires. ²
• New tires for passenger vehicles, trucks, buses, off-road and industrial equipment (scope is tire manufacturing; specific vehicle types are not restricted by NAICS text). ²
• New aircraft tires classified to 326211 (Schedule B 401130 maps to this NAICS). ³
• Excludes retreading or rebuilding activities, which are classified to 326212. ²

NAICS hierarchy and scope notes

• Placement: Sector 31–33 Manufacturing → Subsector 326 Plastics and Rubber Products → Industry group 32621 Tire Manufacturing → U.S. industry 326211. ²
• Boundary with retreading: retreading/rebuilding is 326212. ²
• Related boundaries (at industry‑group level): tire repair services fall under 81119 and retail tire dealers under 44132, per 32621 cross‑references. ²

2022 vintage usage in federal statistics

Census Bureau programs are transitioning publications to the 2022 NAICS basis. The 2022 Economic Census “First Look” began in January 2024, with broader adoption targeted by the end of 2027. Users should confirm whether a specific data series has migrated to 2022 codes before comparing time periods. ⁴

Frequently asked questions

• How is 326211 different from 326212?
  326211 covers manufacturing of new pneumatic tires and inner tubes from rubber. Retreading or rebuilding used tires is explicitly excluded and classified under 326212. This boundary is stated in the 32621 industry group definition and cross‑references. ²

• Are inner tubes included in 326211?
  Yes. The industry definition includes establishments primarily engaged in manufacturing tires and inner tubes from natural and synthetic rubber. This applies regardless of vehicle category; if the product is a new rubber inner tube, it is within 326211. ²

• Which PSCs typically align with tire product buys?
  Common product PSCs include 2610 (Tires and Tubes, Pneumatic, Except Aircraft), 2620 (Aircraft), and 2630 (Solid and Cushion). Use the current PSC Manual for authoritative definitions and to verify scope for aircraft versus non‑aircraft items. ⁵

• Does 326211 cover aircraft tires?
  Yes. Census foreign trade materials map Schedule B 401130 (new pneumatic tires for aircraft) to NAICS 326211, reflecting that new aircraft tires are classified in this manufacturing industry rather than the retreading industry. ³

• How is 326211 used in the Economic Census?
  The 2022 Economic Census publishes detailed industry statistics on the 2022 NAICS basis, which includes 326211. As programs phase in 2022 codes through 2027, confirm the code vintage used in specific tables before making comparisons across years. ⁴
