HS Code for Dyeing auxiliary

Dyeing auxiliaries are classified under HS code 3809.91. These substances are chemical preparations used in the textile industry to enhance the dyeing process, improve dye uptake, or ensure color uniformity. Heading 38.09 covers finishing agents, dye carriers to accelerate the dyeing or fixing of dyestuffs, and other products and preparations used in the textile, paper, or leather industries. Subheading 3809.91 is specifically reserved for those used in the textile industry or similar industries, provided they are not based on amylaceous (starchy) substances. These auxiliaries include leveling agents, wetting agents, and fixatives that do not have the primary function of a dye themselves but are essential for the application of color to fibers.

Products Included

• Textile leveling agents
• Dyeing carriers for polyester
• Color fixatives for reactive dyes
• Wetting agents for textile dyeing
• Dispersing agents used in textile vats

Common Misclassification

Dyeing auxiliaries are sometimes incorrectly classified under HS code 3204, which is reserved for synthetic organic coloring matter (the dyes themselves). Auxiliaries do not impart color but assist the process. Another common error is classification under 3809.10, which is only for agents with a basis of amylaceous substances (starch). Furthermore, if the product is a simple surfactant not specifically prepared as a textile auxiliary, it might be misclassified under 3402.90.
