These raw materials are used in chemical manufacturing, processing, or refining. Manufactured bulk chemicals are combined and used to make various downstream chemical products. These chemical products may, successively, be employed as feedstock for chemical products further downstream, for various industrial activities and services as single chemicals or in arrangements, or may be used to make consumer products.
