NAICS 333132

Overview

The North American Industry Classification System (NAICS) is the federal standard for classifying business establishments so statistical agencies can collect, analyze, and publish data about the U.S. economy. Developed under the Office of Management and Budget and adopted in 1997, NAICS is revised periodically, with the latest comprehensive update in 2022 to maintain comparability across the United States, Canada, and Mexico. It is the foundation for federal economic statistics, procurement market sizing, and industry analyses. ²

NAICS 333132 covers establishments primarily engaged in manufacturing oil and gas field machinery and equipment, including drilling and production machinery and derricks, as well as water well drilling machinery. Federal programs and datasets use this code to identify manufacturing activity specific to oil and gas field equipment. Cross‑references in the official NAICS description distinguish this industry from adjacent manufacturing categories (e.g., mining machinery, shipbuilding, and general-purpose pumps). ¹

What this NAICS covers

• Oil and gas field drilling machinery manufacturing. ¹
• Oil and gas field drilling equipment manufacturing. ¹
• Oil and gas field production machinery and equipment manufacturing. ¹
• Oil and gas field derricks manufacturing. ¹
• Water well drilling machinery manufacturing. ¹

Frequently asked questions

• What does NAICS 333132 include?

  • It includes manufacturing of oil and gas field drilling machinery and equipment, production machinery and equipment, and oil and gas field derricks, plus water well drilling machinery. These scope notes come from the official NAICS industry description. ¹

• How is NAICS 333132 different from NAICS 333131?

  • NAICS 333131 covers underground mining machinery (e.g., core drills, mining cars) and mineral beneficiating machinery, while NAICS 333132 covers oil and gas field machinery and equipment, including field derricks and water well drilling machinery. The codes are distinct in NAICS cross‑references. ¹

• Are offshore drilling platforms covered by NAICS 333132?

  • No. Offshore oil and gas well drilling and production floating platforms are classified in NAICS 336611 (Ship Building and Repairing), per the official cross‑reference for 333132. ¹

• What is the current NAICS vintage and who developed NAICS?

  • NAICS was adopted in 1997 under OMB and is updated on a regular cycle, with the latest update in 2022, to align U.S., Canadian, and Mexican industry statistics for North American comparability. ²
