HS code for Polyamide resin: 3908.90
Polyamides, n.e.c. in heading no. 3908, in primary forms.
Classification of polyamide resin under HS 3908.90
Polyamide resin in primary forms is classified under HS code 3908.90 when it does not fall into the specific categories of Polyamide-6, -11, -12, -6,6, -6,9, -6,10, or -6,12. This code is part of Chapter 39, which covers plastics. Heading 3908 specifically addresses polyamides in primary forms, such as granules, pellets, or powders. The subheading 3908.90 serves as a residual category for "other" polyamides, including various copolymers and specialty aromatic polyamides (aramids) that are not explicitly named in the 3908.10 subheading. These resins are essential in the production of high-strength fibers, automotive components, and industrial plastics. The classification depends entirely on the chemical identity of the polymer and its physical state as a primary form rather than a finished article.

Codes often confused with 3908.90
Common mistake. The most common error is classifying these resins under 3908.10, which is strictly reserved for the standard types like Nylon 6 or Nylon 6,6. If the resin is already processed into a shape, such as a monofilament with a diameter exceeding 1mm, it should be classified under 3916.90. Additionally, if the resin is mixed with other materials to the point of becoming a chemical preparation of Chapter 38, it may be misclassified, though Chapter 39 usually takes precedence for polymers.
Top exporters and importers of HS 390890 (the code used for polyamide resin), 2025
In 2025, the largest exporter of HS 390890 (the code used for polyamide resin) in UN Comtrade data was Germany, with 18% of world exports; the largest importer in UN Comtrade data was China, with 18% of world imports. Countries that did not report 2025 data are estimated from partner records, which can understate them.
Figures cover everything classified under HS 390890, not only polyamide resin.

How these figures are built
109 countries reported 2025 trade to UN Comtrade in HS 2022, and their own totals are used. Countries that did not report are estimated from what other countries recorded trading with them. 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 polyamide resin
What is the HS code for Polyamide resin?
The HS code for Polyamide resin is 390890 (Polyamides; n.e.c. in heading no. 3908, in primary forms). The HS code for specialty or "other" polyamide resins in primary forms is 3908.90. Standard nylons are under 3908.10.
How do I classify Polyamide resin for customs?
Polyamide resin is classified under HS code 390890 — Polyamides; n.e.c. in heading no. 3908, in primary forms. This is a 6-digit subheading level code.
Does this code include liquid polyamide resins?
Yes, primary forms include liquids and pastes, so liquid polyamide resins are classified under 3908.90 provided they are not standard types.
Which countries are the top exporters of polyamide resin (HS 390890)?
In 2025, the top exporters of HS 390890 (the code used for polyamide resin) in UN Comtrade data were Germany ($803M, 18% of world exports), the United States ($766M) and Switzerland ($543M). 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.
