HS Code for Polyethylene terephthalate

Polyethylene terephthalate (PET) in primary forms is classified under HS code 3907.69 based on its chemical structure and physical properties. Heading 3907 covers polyacetals, other polyethers, and epoxide resins, in primary forms; polycarbonates, alkyd resins, polyallyl esters, and other polyesters, in primary forms. PET is a polyester. The specific subheading 3907.69 is reserved for PET with a viscosity number of less than 78 ml/g. Primary forms include liquids, pastes, blocks, lumps, powders, granules, flakes, and similar bulk forms. The classification depends heavily on the technical specification of the polymer's viscosity, which is measured according to ISO 1628-5. If the viscosity exceeds the 78 ml/g threshold, the product would shift to a different subheading. This distinction is crucial for customs purposes as different viscosity grades are used for different industrial applications, such as textile fibers versus bottle-grade resins. The classification follows GRI 1 and 6, focusing on the chemical identity and the specific viscosity metric defined in the HS nomenclature for this specific polyester type.

Products Included

• Low-viscosity PET resin
• PET granules for textile applications
• PET flakes in primary form
• Amorphous PET pellets
• PET powder for industrial coatings

Common Misclassification

The most frequent misclassification occurs with HS code 3907.61, which is for PET with a viscosity number of 78 ml/g or higher. This higher viscosity PET is typically "bottle-grade" used for carbonated soft drink containers. Importers must provide laboratory test reports to justify using 3907.69. Additionally, PET in the form of waste or scrap should be classified under 3915.90, not 3907. If the PET has been processed into sheets or film, it moves to 3920.62. Confusing primary forms with semi-finished products is a common compliance error that leads to incorrect duty payments.

FAQ

What is the HS code for Polyethylene terephthalate?

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

How is the viscosity of PET measured for classification?

It is typically measured in a solution of phenol and 1,2-dichlorobenzene (60/40 by weight) at 25 degrees Celsius, following the ISO 1628-5 standard.
