HS code for Melamine formaldehyde resin: 3909.20
Amino-resins, melamine resins, in primary forms.
Classification of melamine formaldehyde resin under HS 3909.20
Melamine formaldehyde resin is classified under HS code 3909.20, which falls within Chapter 39 of the Harmonized System covering plastics and articles thereof. Specifically, Heading 3909 covers amino-resins, phenolic resins, and polyurethanes in primary forms. Melamine resins are a type of amino-resin formed by the condensation of melamine with formaldehyde. The term "primary forms" is strictly defined in Note 6 to Chapter 39 and includes liquids, pastes, blocks, lumps, powders, granules, and similar bulk forms. This classification is based on the chemical composition of the polymer. Melamine formaldehyde is valued for its hardness, heat resistance, and chemical stability, often used in the production of laminates, molding compounds, and coatings. It is crucial to distinguish the resin in its raw, primary form from finished articles made from the resin, as the latter are classified elsewhere based on their function or form. For example, a bag of melamine resin powder used for industrial molding is 3909.20, but a melamine plate is 3924.10. The classification remains 3909.20 even if the resin contains additives like fillers (e.g., wood flour or cellulose), pigments, or plasticizers, provided the melamine resin remains the essential polymer component. This code is used globally to track the trade of these thermosetting plastics, which are vital in the construction, automotive, and kitchenware industries. Importers should provide a Material Safety Data Sheet (MSDS) to confirm the chemical identity as a melamine-based amino-resin.

Codes often confused with 3909.20
Common mistake. The most common misclassification is with 3909.10, which is for urea resins. While both are amino-resins, they have different chemical structures and properties. Another error is classifying finished products, like melamine tableware, under this code; finished goods belong in 3924.10. Additionally, melamine chemical (the monomer) is classified in 2933.61, not 3909.20.
Top exporters and importers of HS 390920 (the code used for melamine formaldehyde resin), 2025
In 2025, the largest exporter of HS 390920 (the code used for melamine formaldehyde resin) in UN Comtrade data was China, with 15% of world exports; the largest importer in UN Comtrade data was Germany, with 9.5% 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 390920, not only melamine formaldehyde 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).
