HS code for PET resin: 3907.69
Poly(ethylene terephthalate), in primary forms, having a viscosity of less than 78ml/g.
Classification of PET resin under HS 3907.69
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.

Codes often confused with 3907.69
Common mistake. 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.
Top exporters and importers of HS 390769 (the code used for PET resin), 2025
In 2025, the largest exporter of HS 390769 (the code used for PET resin) in UN Comtrade data was China, with 28% of world exports; the largest importer in UN Comtrade data was Vietnam, with about 11% of world imports. Countries that did not report 2025 data are estimated from partner records, which can understate them.

How these figures are built
109 countries reported 2025 trade to UN Comtrade in HS 2022, and their own totals are used. Countries marked * did not, so their figures add up what other countries recorded trading with them, and their exports are valued at buyers' CIF prices. Those estimates miss trade with other non-reporting countries, so they can be low, and a non-reporting country can rank higher than shown or be missing from the list. World totals add both and leave out trade between two non-reporting countries. Figures are in current US dollars; reported imports are mostly valued CIF and exports FOB, and exports include re-exports. The UN Comtrade links show the underlying records; they can also list a few reporters left out here (regional groups and older HS editions).

Questions about PET resin
What is the HS code for PET resin?
The HS code for PET resin is 390769 (Poly(ethylene terephthalate); in primary forms, having a viscosity of less than 78ml/g). For PET resin with a viscosity of less than 78 ml/g, the HS code is 3907.69.
How do I classify PET resin for customs?
PET resin is classified under HS code 390769 — Poly(ethylene terephthalate); in primary forms, having a viscosity of less than 78ml/g. This is a 6-digit subheading level code.
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.
Which countries are the top exporters of PET resin (HS 390769)?
In 2025, the top exporters of HS 390769 (the code used for PET resin) in UN Comtrade data were China ($1.2B, 28% of world exports), South Korea ($537M) and Belgium ($250M). World exports came to about $4.4B, adding countries' reported figures and partner-based estimates for those that did not report (UN Comtrade data). Countries that did not report 2025 data are estimated from partner records, which can understate them.
Which countries are the top importers of PET resin (HS 390769)?
