Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If polymerized into melamine-formaldehyde resin
Polymerized forms are plastics of heading 3909, not pure chemical compounds of Chapter 29.
If formulated as polycondensation coloring preparation
Mixtures with pigments for retail sale fall under Chapter 32 as paints and varnishes.
If imported as chemical preparation with additives exceeding Chapter 29 specifications
Preparations not chemically defined shift to mixtures of Chapter 38.
