Polyadipate Ester Resin Pellets from Mexico
Polyadipate ester resin pellets, made from adipic acid and diols, used as plasticizers and in polyurethane production, imported as primary pellets. These polyesters are classified under 3907.99.00 as other polyesters, as they are not specifically named in other subheadings and meet the definition of a polyester in primary form. The adipic acid and diol monomers form ester linkages, and the product is not a composition with additives exceeding 1% by weight.

Import Tips
• Confirm the pellets are not used as plasticizers in a way that would classify them under heading 38.12 or 38.14, which cover prepared plasticizers
• Keep documentation on the polymer's molecular structure to support classification as a polyester
• Verify the pellets are in primary form, as defined in chapter note 6
