About HS Code 390799
This HS code covers saturated polyesters in primary forms (pellets, chips, powders) that are not specifically classified elsewhere within heading 3907, and importantly, lack the carbon-carbon double bonds found in unsaturated polyesters. This broad category includes a diverse range of polyesters used in various applications where thermosetting is not required. Examples include certain types of engineering plastics, hot melt adhesives, powder coatings, and specialty fibers. Major importers are countries with advanced manufacturing industries, including automotive, electronics, and textiles, such as China, Germany, and Japan. Exporters are typically large chemical and polymer producers globally. Key aspects of trade involve the specific properties tailored for different applications, such as high temperature resistance, chemical resistance, or flexibility. The "saturated" nature means they are generally thermoplastic and can be re-melted and re-processed, offering different advantages compared to their unsaturated counterparts.
Products Under This Code
Polybutylene terephthalate (PBT) resin, Polytrimethylene terephthalate (PTT) resin, Polycyclohexylenedimethylene terephthalate (PCT) resin, Saturated polyester resin for powder coatings, Copolyester hot melt adhesives, Thermoplastic polyester elastomers (TPEs)
Real World Examples
BASF Ultradur (PBT), DuPont Sorona (PTT), Eastman Tritan (Copolyester), Arkema Rilsan (Polyester), Evonik Vestodur (PBT)
Common Misclassification
The main confusion arises with unsaturated polyesters (390791) if the saturation characteristic is not correctly identified. It can also be mistaken for other types of plastics if the "polyester" chemical identity is not confirmed.
Products Classified Under 3907.99
