Trogamid T Resin Pellets
Trogamid T is a transparent polyamide copolymer resin made from bis(4-amino-3-methylcyclohexyl)methane, isophthalic acid, and laurolactam, supplied in primary pellet form for injection molding. It falls under HTS 3908.90.2000 as it precisely matches the defined copolymer composition where the specified monomer units predominate by weight per Chapter 39 subheading notes. This engineering plastic offers high transparency and chemical resistance for demanding applications.

Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If predominantly polyamide-6,6 composition
Chapter 39 notes require classification by predominant monomer unit; shifts to 3908.10 if bis(4-amino-3-methylcyclohexyl)methane units <95%.
If chemically modified version
Subheading note (a)(3) places chemically modified polymers in 'Other' if not specifically covered, but unmodified goes to predominant monomer subheading.
If supplied as polymer blend with polysulfides
Polymer blends classified by predominant components; if blended, may shift to Chapter 39 heading 3911 for polysulfide-containing mixtures.
