Subpart C.—Finished Organic Chemical Products Subpart C headnotes: 1. The provisions of this subpart providing for products obtained, derived, or manufactured in whole or in part from products described in subpart A or B of this part shall also apply to products of like chemical composition having a benzenoid, quinoid, or modified benzenoid structure artificially produced by synthesis, whether or not obtained, derived, or manufactured in whole or in part from products described in the said subpart A or B. 2. The term "pesticides" in items 408.16 to 408.36, inclusive, means products, such as insecticides, rodenticides, fungicides, herbicides, fumigants, and seed disinfectants, chiefly used to destroy undesired animal or plant life. 3. The term "plastics materials" in items 408.44 to 409.18, inclusive, embraces products formed by the condensation, polymerization, or copolymerization of organic chemicals and to which plasticizers, fillers, colors, or extenders may have been added. The term includes, but is not limited to, phenolic and other tar - acid resins, styrene resins, alkyd and polyester resins based on phthalic anhydride, coumarone-indene resins, urethane, epoxy, toluene sulfonamide, maleic, fumaric, aniline, and polyamide resins, and other synthetic resins. The plastics materials may be in solid, semi-solid, or liquid condition, such as flakes, powders, pellets, granules, solutions, emulsions, and other basic forms not further processed. 4. For the purpose of the classification of merchandise provided for under items 408.44 to 409.18, inclusive, the following provisions shall apply: (a) The term "thermoplastic resins" means those materials in unfinished forms which in their final state as finished articles are capable of being repeatedly softened by increase of temperature and hardened by decrease of temperature. (b) The term "thermosetting resins" (or thermosets) means those materials in unfinished forms which in their final state as finished articles are substantially infusible. Thermosetting resins are often liquids at some stage in their manufacture or processing and are cured by heat, catalysis, or other chemical means. After being fully cured, thermosets cannot be resoftened by heat.
