Machinery Manufacturing

Analysis

NAICS 333 is the 2022 subsector for machinery manufacturing. Census lists 1067 example activities under it in the official index.

County Business Patterns counts 21,668 US establishments in this code in 2023, employing 1,086,146 people at an average annual payroll of $78,310 per employee (67th percentile of national industries). 29% of the establishments have fewer than five employees, which is close to the national mix.

Across its national industries Census lists 1067 index entries; typical ones are bale throwers manufacturing, attachments, powered lawn and garden equipment…, aggregate spreaders manufacturing and amalgamators (i.e., metallurgical and mining machinery)….

Its goods appear in 1199 statistical lines of the US tariff schedule, mostly under headings 8462 (machine tools (including presses) for working metal by…), 8465 (machine tools (including machines for nailing, stapling…) and 8414 (air or vacuum pumps, air or other gas compressors and fans…). That link is how import data is matched to domestic producers, for example in trade-remedy cases.

It splits into 7 more detailed codes. The largest by establishments is 3339 (Other General Purpose Machinery Manufacturing) with 5,940.

Its more detailed codes are 3331 Agriculture, Construction, and Mining Machinery Manufacturing (2,805 establishments), 3332 Industrial Machinery Manufacturing (2,836 establishments), 3333 Commercial and Service Industry Machinery Manufacturing (1,731 establishments), 3334 Ventilation, Heating, Air-Conditioning, and Commercial Refrigeration Equipment Manufacturing (1,685 establishments), 3335 Metalworking Machinery Manufacturing (5,772 establishments) and 3336 Engine, Turbine, and Power Transmission Equipment Manufacturing (899 establishments) and 1 more.

Official definition

Industries in the Machinery Manufacturing subsector create end products that apply mechanical force, for example, the application of gears and levers, to perform work. Some important processes for the manufacture of machinery are forging, stamping, bending, forming, and machining that are used to shape individual pieces of metal. Processes, such as welding and assembling are used to join separate parts together. Although these processes are similar to those used in metal fabricating establishments, machinery manufacturing is different because it typically employs multiple metal forming processes in manufacturing the various parts of the machine. Moreover, complex assembly operations are an inherent part of the production process.

In general, design considerations are very important in machinery production. Establishments specialize in making machinery designed for particular applications. Thus, design is considered to be part of the production process for the purpose of implementing NAICS. The NAICS structure reflects this by defining industries and industry groups that make machinery for different applications. A broad distinction exists between machinery that is generally used in a variety of industrial applications (i.e., general purpose machinery) and machinery that is designed to be used in a particular industry (i.e., special purpose machinery). Three industry groups consist of special purpose machinery--Agriculture, Construction, and Mining Machinery Manufacturing; Industrial Machinery Manufacturing; and Commercial and Service Industry Machinery Manufacturing. The other industry groups make general purpose machinery: Ventilation, Heating, Air-Conditioning, and Commercial Refrigeration Equipment Manufacturing; Metalworking Machinery Manufacturing; Engine, Turbine, and Power Transmission Equipment Manufacturing; and Other General Purpose Machinery Manufacturing.
