Manufacturing: Chemical, Petroleum, Rubber, Stone, Clay, Glass, and Concrete

The chemical group includes establishments producing basic chemicals as well as establishments manufacturing products by predominantly chemical processes. Establishments classified in this major group manufacture three general classes of products: basic chemicals (e.g., alkalies, salts, and organic chemicals), chemical products to be used in further manufacture (e.g., synthetic fibers, plastics materials, dry colors, and pigments), and finished chemical products to be used for ultimate consumption (e.g., drugs, cosmetics, and soaps) or as materials or supplies in other industries (e.g. paints, fertilizers, and explosives).
