HS Code for Melamine

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.

Products Included

• Pure melamine powder (99% purity or higher)
• Industrial grade melamine monomer
• Melamine crystals for chemical synthesis
• 1,3,5-triazine-2,4,6-triamine

Common Misclassification

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.
