HS Code for PET resin

PET resin with a viscosity of less than 78 ml/g is classified under HS code 3907.69. This falls under Chapter 39, which covers plastics and articles thereof. Heading 3907 includes polyacetals, other polyethers, and epoxide resins, in primary forms; polycarbonates, alkyd resins, polyallyl esters, and other polyesters, in primary forms. Poly(ethylene terephthalate) (PET) is a type of polyester specifically identified under subheading 3907.6. The subheading is further divided based on the intrinsic viscosity of the polymer. Viscosity is measured according to the ISO 1628-5 standard, typically using a solution of the resin in a mixture of phenol and 1,2-dichlorobenzene. Resins with a viscosity of less than 78 ml/g are typically used for applications like textile fibers or certain types of thermoforming, whereas higher viscosity resins are used for bottle-grade PET. The term "primary form" is defined in Note 6 to Chapter 39 and refers to liquids, pastes, blocks, lumps, powders, granules, flakes, and similar bulk forms. The classification is determined by the chemical composition and the physical property of viscosity, which is a critical technical parameter for customs authorities to distinguish between different grades of polyester resin.

Products Included

Common Misclassification

The most common misclassification is HS code 3907.61, which is for PET with a viscosity of 78 ml/g or higher. Importers must have a laboratory analysis to confirm the viscosity to ensure the correct subheading is used. Another error is using 3907.99 for "other" polyesters, but since PET has its own specific subheading (3907.6), it must be used. Recycled PET in primary form is also classified here based on its viscosity.

FAQ

What is the HS code for PET resin?

For PET resin with a viscosity of less than 78 ml/g, the HS code is 3907.69.

How is PET viscosity determined for HS classification?

It is determined by the ISO 1628-5 standard, which measures the flow of the polymer in a specific solvent mixture to calculate intrinsic viscosity.
