Import Tips & Compliance
• Keep records of the resin's chemical composition, including monomer ratios, to prove it is PBT with 95% purity
• Check if the resin contains additives like flame retardants or colorants, as these may affect classification under subheading note 2
• Consult the CBSA's tariff classification advice service for binding rulings on new products

Bio-based Polyethylene Furanoate (PEF) Granules
Bio-based polyethylene furanoate (PEF) granules are a sustainable polyester from furandicarboxylic acid and ethylene glycol, used for bottles and films. They are in primary forms and qualify as other polyesters under this tariff item since furanoate units predominate.
Celanex PBT Pellets
Celanex® 1600A polybutylene terephthalate (PBT) pellets, a pure resin used for automotive under-hood components and electrical parts. This product is a polyester in primary form, specifically PBT where the butylene terephthalate monomer units contribute 95% or more by weight, meeting the purity standards of subheading note 1. It is classified under tariff item 3907.99.00 as 'other polyesters' not elsewhere specified.
Copolyester Elastomer (COPE) Granules
Thermoplastic copolyester elastomer (COPE) granules, such as Hytrel, combining hard polyester segments with soft polyether segments, supplied in primary granules. These copolymers are classified under 3907.99.00 as other polyesters, as the polyester blocks predominate by weight over the polyether blocks, per chapter note 4. The product is in primary form and not covered by a more specific subheading.
Copolyester Elastomer (COPE) Pellets
Copolyester elastomer (COPE) pellets, like Hytrel, are thermoplastic elastomers combining polyester hard segments with polyether soft segments for hoses and belts. They are in primary forms and qualify as other polyesters where polyester units predominate over polyether units.
High IV Polyester Staple Fiber Resin
High intrinsic viscosity polyester staple fiber resin is specialized polyester chips for staple fiber production, not textile grade PET. It is in primary forms and qualifies as other polyesters under this tariff item with specialized IV greater than 0.70.
Liquid Crystal Polyester (LCP) Resin
High-performance liquid crystal polyester (LCP) resin for electronics connectors, featuring rigid aromatic monomers, in primary injection form. This polyester is classified under 3907.99.00 as other polyesters, as it is not specifically named in other subheadings and meets the definition of a polyester in primary form. The aromatic monomer units form ester linkages, and the product is not a composition with additives exceeding 1% by weight.
