All Other Basic Organic Chemical Manufacturing

This includes establishments primarily engaged in manufacturing basic organic chemical products (except aromatic petrochemicals, industrial gases, synthetic organic dyes and pigments, gum and wood chemicals, cyclic crudes and intermediates, and ethyl alcohol).

Illustrative Examples:

Biodiesel fuels not made in petroleum refineries and not blended with petroleum
Calcium organic compounds, not specified elsewhere by process, manufacturing
Carbon organic compounds, not specified elsewhere by process, manufacturing
Enzyme proteins (i.e., basic synthetic chemicals) (except pharmaceutical use) manufacturing
Organo-inorganic compound manufacturing
Fatty acids (e.g., margaric, oleic, stearic) manufacturing
Plasticizers (i.e., basic synthetic chemicals) manufacturing
Raw organic waxes manufacturing
Refrigerant mixtures and blends manufacturing
Silicone (except resins) manufacturing
Synthetic sweeteners (i.e., sweetening agents) manufacturing

Plastics Material and Resin Manufacturing

This includes establishments primarily engaged in (1) manufacturing resins, plastics materials, and nonvulcanizable thermoplastic elastomers and mixing and blending resins on a custom basis and/or (2) manufacturing noncustomized synthetic resins.

Nonferrous Metal (except Aluminum) Smelting and Refining

Establishments in this category are primarly engaged in (1) smelting ores into nonferrous metals and/or (2) the primary refining of nonferrous metals (except aluminum) by electrolytic methods or other processes.

Nonferrous Metal (except Copper and Aluminum) Rolling, Drawing, and Extruding

This includes establishments primarily engaged in (1) rolling, drawing, or extruding shapes (e.g., bar, plate, sheet, strip, tube) from purchased nonferrous metals and/or (2) recovering nonferrous metals from scrap and rolling, drawing, and/or extruding shapes (e.g., bar, plate, sheet, strip, tube) in integrated mills.

Secondary Smelting, Refining, and Alloying of Nonferrous Metal (except Copper and Aluminum)

This includes establishments primarily engaged in (1) alloying purchased nonferrous metals and/or (2) recovering nonferrous metals from scrap. Establishments in this industry make primary forms (e.g., bar, billet, bloom, cake, ingot, slab, slug, wire) using smelting or refining processes.
