3809.92 - Of a kind used in the paper or like industries:

This HTS category, 3809.92, encompasses finishing agents, dye carriers, and other preparations specifically designed for use in the paper industry or similar industrial applications. These products are formulated to enhance processes such as dyeing, fixing of dyestuffs, or to impart specific finishes to paper and related materials. Their function is to improve the quality, appearance, or processing efficiency of paper products.

Unlike its sibling category, 3809.91, which covers similar agents for the textile or like industries, or 3809.93 for the leather industry, this classification is exclusive to paper-related applications. The distinction lies in the intended end-use and the specific formulations that cater to the unique requirements of papermaking and paper finishing.

Within 3809.92, further subdivisions exist to refine classification based on the chemical composition of the products. Subcategory 3809.92.10 distinguishes products containing 5 percent or more by weight of aromatic or modified aromatic substances, while 3809.92.50 covers all other preparations within this paper industry scope. This granular breakdown allows for more precise tariff application based on the specific chemical makeup of the finishing agents.
