NAICS 336360

Overview

The North American Industry Classification System (NAICS) is the federal standard for classifying business establishments to collect, analyze, and publish statistics on the U.S. economy. It is maintained by the Office of Management and Budget in coordination with Canada and Mexico and is updated on a five-year cycle, most recently in 2022. ²
U.S. industry 336360 covers establishments primarily engaged in manufacturing motor vehicle seating, seats, seat frames, seat belts, and interior trimmings. Federal statistical programs use this code to delineate production activity within the broader motor vehicle parts segment and to ensure consistent, non-overlapping categorization of such products across censuses and surveys. ¹

What this NAICS covers

• Manufacturing of motor vehicle seating systems. ¹
• Production of individual motor vehicle seats. ¹
• Fabrication of seat frames and related mechanisms. ¹
• Manufacturing of motor vehicle seat belts. ¹
• Production of interior trimmings for motor vehicles. ¹
• Excludes convertible tops and air bags, which fall under 336399. ¹

Scope notes and cross‑references

• In-scope: facilities whose primary products are motor vehicle seating, seat frames, seat belts, and interior trim components. ¹
• Out-of-scope: establishments primarily making vehicle convertible tops or air bags; these are classified in 336399. ¹
• NAICS group context: 336360 is part of Industry Group 3363, Motor Vehicle Parts Manufacturing, used for economic census and survey tabulations. ¹

Frequently asked questions

• What products are included under NAICS 336360?
  Establishments manufacturing motor vehicle seating, seats, seat frames, seat belts, and interior trimmings are included. The classification is production-oriented, focusing on processes and primary products rather than end-use. This helps ensure consistent statistical reporting across plants that specialize in interior seating and trim components. ¹

• Are air bags or convertible tops counted in NAICS 336360?
  No. Air bags and convertible tops are explicitly cross-referenced to 336399 (All Other Motor Vehicle Parts Manufacturing). Establishments primarily producing these products should not be classified under 336360, even if they also make related interior components. ¹

• How current is the NAICS structure used for this industry?
  Federal statistical programs currently use the 2022 NAICS vintage, reflecting the most recent five-year revision cycle managed by OMB in collaboration with Canada and Mexico. Future revisions follow the same cycle to maintain international comparability and reflect industry changes. ²

• How does NAICS 336360 relate to other motor vehicle parts industries?
  It is distinct from 336370 (metal stampings) and from “all other” categories such as 336399, as well as specialized segments like 336391 (motor vehicle air-conditioning). These boundaries minimize overlap and support accurate, comparable statistics. ¹
