Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If the resin is a homopolymer of a single amide monomer
Homopolymers with 95% or more of one monomer are classified under the specific polyamide subheading.

Bio-based Polyamide-4,10 Resin
Bio-based polyamide-4,10 resin beads with 95% or more monomer units from sebacic acid, falling under 'Other' polyamides in primary forms. This polyamide is not specifically named in subheading 3908.10, so it is classified as 'Other' polyamides.
Engineering Grade Trogamid CX Pellets
Trogamid CX engineering resin pellets, a copolyamide of bis(4-amino-3-methylcyclohexyl)methane, isophthalic acid, and laurolactam, in primary form for 3D printing filament production. This copolyamide does not meet the 95% monomer threshold for a named polyamide subheading, so it falls under 'Other' polyamides in primary forms.
Grilamid TR Transparent Polyamide Pellets
Grilamid TR pellets, a semi-crystalline copolyamide based on bis(4-amino-3-methylcyclohexyl)methane, isophthalic acid, and laurolactam, in primary granular form for extrusion and molding. As a copolymer without a single predominant monomer reaching 95%, it is classified under 'Other' polyamides.
High-Clarity Polyamide Copolymer Resin for Eyewear
High-clarity pelletized resin from bis(4-amino-3-methylcyclohexyl)methane-isophthalic acid-laurolactam copolymer, in primary form for injection-molded eyewear frames. This copolyamide is not a named polyamide in subheading 3908.10 and is therefore classified as 'Other' polyamides.
High-Viscosity Polyamide-610
Polyamide-610 pellets with high melt viscosity from hexamethylenediamine and sebacic acid, with 95% or more monomers, classified as 'Other' polyamides. This polyamide is not specifically named in subheading 3908.10, so it falls under 'Other' polyamides in primary forms.
Laurolactam-Based Transparent PA Resin Pellets
Primary pellets of laurolactam-isophthalic acid-bis(4-amino-3-methylcyclohexyl)methane copolymer for medical device molding. The copolymer composition does not meet the 95% threshold for named polyamides, so it falls under 'Other' polyamides in primary forms.
