NAICS 336992

Overview

The North American Industry Classification System (NAICS) is the federal standard for grouping business establishments to collect, analyze, and publish statistics about the U.S. economy. Developed under the Office of Management and Budget in cooperation with Canada and Mexico, NAICS replaced the SIC system in 1997 and is updated on a five-year cycle; the current vintage is 2022. ¹
NAICS 336992 covers establishments primarily engaged in manufacturing complete military armored vehicles, combat tanks, specialized tank components, and self-propelled weapons. Federal agencies use this industry code for statistical reporting and as one basis for contract classification. ²

What this NAICS covers

• Combat tank manufacturing (complete systems and platforms). ²
• Military armored fighting vehicle production (tracked or wheeled, as armored end items). ²
• Self-propelled weapon systems manufacturing (e.g., self-propelled artillery). ²
• Specialized tank components (e.g., turrets, hull structures, armor packages). ²
• Armored vehicle chassis and integrated hull fabrication. ²
• Integration of weapon, mobility, and protection subsystems into armored platforms. ²

Frequently asked questions

• What does NAICS 336992 include and exclude?
  It includes manufacturing complete military armored vehicles, combat tanks, specialized tank components, and self-propelled weapons. Typical exclusions include nonarmored military universal carriers and other nonarmored vehicles, which are classified under NAICS 336112 or related highway vehicle industries as appropriate. ²

• How is NAICS 336992 different from NAICS 336120 and 336999?
  NAICS 336992 covers armored vehicles, tanks, and self-propelled weapons. Heavy-duty highway vehicles belong in 336120, while “all other” transportation equipment—excluding armored vehicles and tanks—belongs in 336999. Review NAICS definitions and cross-references before assigning a code. ²

• Which PSCs commonly align with armored vehicle and tank buys?
  Tracked combat vehicles often align with PSC 2350; wheeled combat vehicles may align with PSC 2355. Component buys can map to PSC Group 25 classes, such as 2530 (Vehicle Brake, Steering, Axle, Wheel Components). Always confirm definitions in the PSC Manual. ⁵

• What is the small business size standard for NAICS 336992?
  SBA establishes size standards by NAICS code. For manufacturing codes, standards are typically employee-based and are periodically adjusted. Consult SBA’s Table of Small Business Size Standards for the current threshold associated with NAICS 336992 and effective dates. ⁴

• When was NAICS last updated and what vintage is used now?
  NAICS is reviewed every five years. The latest vintage is 2022, and Census programs adopt it on a staggered timeline. Check the Census implementation page for program-by-program adoption details and dates. ³
