More Specific Codes
This product may fall under a more specific subheading:
Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If alkyd resin modified
Alkyd-modified variants have specific subheadings within other polyesters.
If for PVC copolymer blends
If PVC monomers predominate, classification shifts to vinyl chloride polymers.
If imported as pre-colored non-primary plates
Processed into plates/sheets beyond primary form moves to Chapter 39 heading 3920.

Import Tips & Compliance
• Include technical data sheets confirming polyester nature and monomer weight percentages; ensure granules are free-flowing primary form, not molded; check for REACH compliance documentation for EU-origin materials
Related Products under HTS 3907.99.50
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.
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.
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.
