HS Code 3909.10 – Amino-resins; urea and thiourea resins, in primary forms
HS code 3909.10 is the 6-digit subheading for amino-resins, urea and thiourea resins, in primary forms. It is used for urea-formaldehyde resin powder, liquid urea-formaldehyde resin, UF adhesive, thiourea-formaldehyde resin and UF molding compounds.
What HS 3909.10 covers
This HS code encompasses urea and thiourea resins in their primary forms, predominantly urea-formaldehyde (UF) resins. These thermosetting amino-resins are fundamental to the manufacturing of wood-based panels such as particleboard and medium-density fiberboard (MDF), serving as highly effective and cost-efficient adhesives. They are also utilized in certain coatings and molding compounds. International trade involves large chemical companies, resin producers, and manufacturers in the construction and furniture sectors. Critical trade considerations include varying global formaldehyde emission standards, which influence product specifications, and the need for proper storage and handling due to their reactive nature. These resins are typically traded as powders or liquid concentrates.

Codes often confused with 3909.10
Common mistake. Often confused with 390920 (melamine resins) due to similar applications, but the chemical composition (urea vs. melamine) is distinct. Also, 390931 (ion-exchangers) are amino-resins but serve a specific function.
Top exporters and importers of HS code 390910, 2025
In 2025, the largest exporter of HS code 390910 in UN Comtrade data was Germany, with 23% of world exports; the largest importer in UN Comtrade data was Germany, with 16% 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 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).
