Analysis
NAICS 33313 is the 2022 NAICS industry for mining and oil and gas field machinery manufacturing, part of 3331 (Agriculture, Construction, and Mining Machinery Manufacturing). Census lists 43 example activities under it in the official index.
County Business Patterns counts 888 US establishments in this code in 2023, employing 38,962 people at an average annual payroll of $87,485 per employee (76th percentile of national industries). 23% of the establishments have fewer than five employees, which points to larger operations.
Census lists 5 related activities that belong elsewhere, most often in 33661, 33312, 33392 and 33651. 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.
Across its national industries Census lists 43 index entries; typical ones are amalgamators (i.e., metallurgical and mining machinery)… and bits, rock drill, oil and gas field-type, manufacturing.
Its goods appear in 32 statistical lines of the US tariff schedule, mostly under headings 8207 (interchangeable tools for handtools, whether or not power…), 8430 (other moving, grading, leveling, scraping, excavating…) and 8431 (parts suitable for use solely or principally with the…). That link is how import data is matched to domestic producers, for example in trade-remedy cases.
It splits into 2 more detailed codes. The largest by establishments is 333132 (Oil and Gas Field Machinery and Equipment Manufacturing) with 622.
