Analysis
NAICS 336390 is the 2022 national industry for other motor vehicle parts manufacturing, part of 33639 (Other Motor Vehicle Parts Manufacturing). Census lists 30 example activities under it in the official index.
County Business Patterns counts 1,323 US establishments in this code in 2023, employing 143,867 people at an average annual payroll of $57,696 per employee (28th percentile of national industries). 25% of the establishments have fewer than five employees, which is close to the national mix.
Census lists 9 related activities that belong elsewhere, most often in 336310, 336320, 336330 and 336340. Businesses that do several things are classified by their primary activity, the one that generates the most value, so check those boundaries before settling on this code.
Its index entries, the activities Census uses to assign businesses to this code, include air bag assemblies manufacturing, air bag initiators manufacturing, air filters, automotive, truck, and bus, manufacturing and air-conditioners, motor vehicle, manufacturing, among 30 in all.
Its goods appear in 34 statistical lines of the US tariff schedule, mostly under headings 8708 (parts and accessories of the motor vehicles of headings…), 8716 (trailers and semi-trailers; other vehicles, not…) and 8421 (centrifuges, including centrifugal dryers; filtering or…). That link is how import data is matched to domestic producers, for example in trade-remedy cases.
For example, manufacturing motor vehicle gasoline engines and engine parts are classified in 336310 (Motor Vehicle Gasoline Engine and Engine Parts Manufacturing) instead.
