Product classification
HS code for Urea resin: 3909.10
Amino-resins, urea and thiourea resins, in primary forms.
Classification of urea resin under HS 3909.10
Urea resin, also known as urea-formaldehyde resin, is classified under HS code 390910. This classification is based on its status as an amino-resin in a primary form. Under Chapter 39 of the Harmonized System, which governs plastics and articles thereof, resins produced by the condensation of urea or thiourea with aldehydes are categorized here. These products are typically used as adhesives, molding compounds, or in the production of particle boards and medium-density fiberboard (MDF). The classification applies to the resin in its "primary form," which includes liquids, pastes, blocks, lumps, powders, and granules. Because these are polymers resulting from chemical synthesis rather than simple chemical compounds or fertilizers, they are excluded from Chapters 29 and 31 and placed firmly within the plastics category of the nomenclature.

Codes often confused with 3909.10
Common mistake. The most common misclassification for urea resin is HS code 310210 (Urea fertilizer). While both products share the name "urea," the resin is a polymer used in manufacturing, whereas 310210 is for agricultural nutrients. Another frequent error involves HS code 3506, which covers prepared glues and other prepared adhesives. If the urea resin is specifically formulated with fillers and additives and put up for retail sale as an adhesive, it might fall under 3506; however, the bulk primary resin remains in 390910.
Top exporters and importers of HS 390910 (the code used for urea resin), 2025
In 2025, the largest exporter of HS 390910 (the code used for urea resin) 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).
