Polycyclohexylenedimethylene Terephthalate (PCT) Resin
PCT resin is a high-temperature polyester for electrical components and fibers, imported as primary pellets. Fits 3907.99.50 since cyclohexanedimethanol and terephthalic monomers predominate but lack specific subheading coverage.

Polybutylene Terephthalate (PBT) Resin
Polybutylene terephthalate (PBT) is a thermoplastic polyester resin in primary pellet form used for engineering plastics in automotive and electronics. It falls under HTS 3907.99.50 as an 'other polyester' where the terephthalic acid and butanediol monomers predominate by weight, not meeting specific subheadings like PET or saturated polyesters.
Polytrimethylene Terephthalate (PTT) Pellets
PTT resin pellets are semi-crystalline polyesters used in textiles, carpets, and films, supplied in primary form. Classified in 3907.99.50 as 'other polyesters' since terephthalic and propanediol units predominate but do not fit named subheadings like 3907.60 or 3907.91.
Liquid Crystal Polymer (LCP) Granules
LCP granules are high-performance polyesters with rigid rod-like molecules for electronics connectors and automotive parts. Under 3907.99.50 as other polyesters where hydroxybenzoic acid and similar monomers predominate, not covered by specific named subheadings.
Copolyester Elastomer (COPE) Pellets
COPE pellets like Hytrel are thermoplastic elastomers combining polyester hard segments with polyether soft segments for hoses and belts. Classified 3907.99.50 as other polyesters where polyester units predominate over polyether per subheading note (a)(4).
Bio-based Polyethylene Furanoate (PEF) Granules
PEF is a sustainable polyester from furandicarboxylic acid and ethylene glycol for bottles and films. In 3907.99.50 as other polyesters with furanoate units predominating, distinct from petroleum-based PET.
Thermoplastic Polyester Elastomer TPEE Pellets
TPEE pellets for wire insulation and seals feature polyester crystallizable segments. HTS 3907.99.50 applies as other copolyesters where polyester exceeds other units by subheading note.
