HS Code for Reactive dye

Reactive dyes are classified under HS code 3204.16. This classification is found in Chapter 32, which covers tanning or dyeing extracts, tannins and their derivatives, dyes, pigments, and other coloring matter. Heading 3204 specifically addresses synthetic organic coloring matter, whether or not chemically defined. Subheading 3204.16 is dedicated to reactive dyes and preparations based on these dyes. Reactive dyes are unique because they form a covalent bond with the substrate (usually textile fibers like cotton, wool, or nylon) during the dyeing process, resulting in exceptionally high colorfastness. This code includes the pure dye molecules as well as commercial preparations that may contain diluents, surfactants, or other additives used to standardize the strength and properties of the dye. The classification applies regardless of the physical form (powder, liquid, or paste) as long as the chemical nature of the coloring agent is reactive.

Products Included

• Fiber-reactive dyes
• Vinyl sulfone dyes
• Monochlorotriazine dyes
• Reactive dye preparations
• Cold-brand reactive dyes

Common Misclassification

Reactive dyes are often confused with other subheadings under 3204. For instance, HS code 3204.11 is for disperse dyes, and 3204.12 is for acid dyes. Each of these categories depends on the chemical interaction between the dye and the fiber. Another common error is using 3204.17, which is for synthetic organic pigments. Unlike dyes, pigments do not dissolve and do not bond chemically with the fiber in the same manner as reactive dyes.
