Analysis
NAICS 32521 is the 2022 NAICS industry for resin and synthetic rubber manufacturing, part of 3252 (Resin, Synthetic Rubber, and Artificial and Synthetic Fibers and Filaments Manufacturing). Census lists 124 example activities under it in the official index.
County Business Patterns counts 1,438 US establishments in this code in 2023, employing 100,164 people at an average annual payroll of $93,324 per employee (80th percentile of national industries). 18% of the establishments have fewer than five employees, which points to larger operations.
By establishments it ranks 1st of the 2 codes at this level within Resin, Synthetic Rubber, and Artificial and Synthetic Fibers and Filaments Manufacturing, with 91.8% of them.
Between 2018 and 2023 the number of establishments grew 10% and employment rose 10%. 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.
Across its national industries Census lists 124 index entries; typical ones are acetal resins manufacturing and acrylate rubber manufacturing.
Its goods appear in 121 statistical lines of the US tariff schedule, mostly under headings 4002 (synthetic rubber and factice derived from oils, in primary…), 3907 (polyacetals, other polyethers and epoxide resins, in…) and 3904 (polymers of vinyl chloride or of other halogenated olefins…). That link is how import data is matched to domestic producers, for example in trade-remedy cases.
Official definition
This industry comprises establishments primarily engaged in one or more of the following: (1) manufacturing synthetic resins, plastics materials, and nonvulcanizable elastomers and mixing and blending resins on a custom basis; (2) manufacturing noncustomized synthetic resins; and (3) manufacturing synthetic rubber.
