3809 — Finishing agents, dye carriers to accelerate the dyeing, fixing of dyestuffs, other products and preparations, of a kind used in the textile, paper, leather or like industries, n.e.c. or included
Chapter 38: Miscellaneous chemical products
Plain-language overview
Use HS-4 3809 when importing finishing agents or dye carriers designed to enhance dyeing or fixing processes in textiles, paper, or leather. For example, a shipment of a textile dyeing preparation containing synthetic polymers would fall under this heading.
Choosing the correct subheading within HS-4 3809 is crucial. If your product is a finishing agent based on amylaceous substances, you should classify it under HS-6 380910. However, if it does not contain these substances but is still used in textiles, opt for HS-6 380991.
For products used specifically in the paper industry, HS-6 380992 is appropriate, while HS-6 380993 applies to those used in leather or similar industries. Make sure to differentiate based on the primary industry of use to avoid misclassification.
