About heading 3908

Polyamides in primary forms

Heading 3908 covers polyamides in primary forms: resins, granules, pellets, powders, flakes and similar unformed masses, before they are made into film, fiber or finished parts. It splits three ways: a line for the named polyamide types (nylon 6, 11, 12, 6,6, 6,9, 6,10 and 6,12), a duty-free line for one specified copolymer, and a residual line for all other polyamides and polyamide blends.
