Product classification
HS code for Melamine: 2933.61
Heterocyclic compounds, containing an unfused triazine ring (whether or not hydrogenated) in the structure, melamine.
Classification of melamine under HS 2933.61
Melamine is classified under HS code 2933.61. This classification is based on its chemical identity as a separate chemically defined organic compound. Within Chapter 29, which covers organic chemicals, heading 2933 is dedicated to heterocyclic compounds with nitrogen hetero-atoms only. Melamine, known scientifically as 1,3,5-triazine-2,4,6-triamine, contains an unfused triazine ring in its structure, which places it specifically in the 2933.6 series. Subheading 2933.61 is the specific provision for melamine. For a product to be classified here, it must be the monomeric chemical substance, typically in the form of a white crystalline powder. If the substance has been polymerized or mixed with other materials to form a resin, it is no longer classified in Chapter 29 and must be moved to the plastics chapter.

Codes often confused with 2933.61
Common mistake. The most frequent misclassification is with HS code 3909.20, which covers melamine resins. While melamine is the raw material for the resin, the resin is a polymer and belongs in Chapter 39. Another error involves HS code 3824, which is for prepared binders or chemical mixtures; however, as a separate chemically defined compound, pure melamine must remain in 2933.61 according to the General Rules of Interpretation.
Top exporters and importers of HS 293361 (the code used for melamine), 2025
In 2025, the largest exporter of HS 293361 (the code used for melamine) in UN Comtrade data was China, with 69% of world exports; the largest importer in UN Comtrade data was India, with 11% 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 marked * did not, so their figures add up what other countries recorded trading with them, and their exports are valued at buyers' CIF prices. 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).
