Analysis
NAICS 333515 is the 2022 national industry for cutting tool and machine tool accessory manufacturing, part of 33351 (Metalworking Machinery Manufacturing). Census lists 37 example activities under it in the official index.
County Business Patterns counts 1,060 US establishments in this code in 2023, employing 23,991 people at an average annual payroll of $67,765 per employee (49th percentile of national industries). 38% of the establishments have fewer than five employees, which is close to the national mix.
Its index entries, the activities Census uses to assign businesses to this code, include angle rings (i.e., a machine tool accessory) manufacturing, arbors (i.e., a machine tool accessory) manufacturing, bits and knives for metalworking lathes, planers, and… and bits, drill, metalworking, manufacturing, among 37 in all.
Its goods appear in 30 statistical lines of the US tariff schedule, mostly under headings 8207 (interchangeable tools for handtools, whether or not power…), 8466 (parts and accessories suitable for use solely or…) and 8208 (knives and cutting blades, for machines or for mechanical…). That link is how import data is matched to domestic producers, for example in trade-remedy cases.
Between 2018 and 2023 the number of establishments fell 7% and employment fell 9%. The 2018 count used NAICS 2017, so part of a large move can come from codes being redefined rather than from businesses opening or closing.
For example, manufacturing saw blades, handsaws, and accessories and attachments for saw blades and for nonpowered metal cutting and forming handtools are classified in 332216 (Saw Blade and Handtool Manufacturing) instead.
