HS Code 3908.10 – Polyamides; polyamide-6, -11, -12, -6,6, -6,9, -6,10 or -6,12, in primary forms

HS code 3908.10 is the 6-digit subheading for polyamides, polyamide-6, -11, -12, -6,6, -6,9, -6,10 or -6,12, in primary forms. It is used for polyamide 6 pellets, polyamide 6,6 granules, polyamide 12 resin, polyamide 11 chips and glass-filled PA 6,6.

What HS 3908.10 covers

This specific HS code covers a range of common polyamides (nylons) in primary forms (pellets, granules), including PA 6, PA 11, PA 12, PA 6,6, PA 6,9, PA 6,10, and PA 6,12. These are high-performance engineering thermoplastics known for their excellent mechanical properties, toughness, wear resistance, and chemical resistance. They are widely used in automotive components, electrical and electronic parts, industrial machinery, consumer goods, and textile fibers. Major importers are countries with strong manufacturing sectors in these areas, such as China, Germany, the USA, and Japan. Exporters are leading chemical and polymer manufacturers from Europe, North America, and Asia. Key aspects of trade include the demand for lightweight and durable materials across various industries, the specific performance requirements of each polyamide type (e.g., PA 6,6 for high strength, PA 12 for flexibility), and the ongoing innovation in polymer blends and composites.

Codes often confused with 3908.10

Common mistake. This code is very specific to certain polyamide types; misclassification can occur if other polyamides (390890) are incorrectly grouped here or if the specific "nylon" type is not accurately identified. It could also be confused with other engineering plastics like polyacetals (390710) or polycarbonates (390740).

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).
