3809.93.10.00 - Containing 5 percent or more by weight of one or more aromatic or modified aromatic substances

This HTS category, 3809.93.10.00, specifically covers finishing agents, dye carriers, and other preparations used in the textile, paper, leather, or similar industries that contain five percent or more by weight of one or more aromatic or modified aromatic substances. These products are designed to enhance the dyeing or fixing of dyestuffs, or to impart specific finishes to materials. Examples within this classification might include certain synthetic tanning agents or specialized finishing chemicals used in the leather industry that meet the specified aromatic content threshold.

This particular subcategory is distinguished from its sibling, 3809.93.50.00 ("Other"), by the explicit requirement of containing a significant proportion of aromatic or modified aromatic substances. While both fall under "Other" preparations for the leather or like industries within the broader finishing agents heading, 3809.93.10.00 is more narrowly defined by the chemical composition, focusing on the presence of these specific types of aromatic compounds. Products classified under 3809.93.50.00 would encompass preparations for the leather industry that do not meet this aromatic content criterion or are otherwise not specifically described within this more specialized subcategory.

As this is a leaf node in the HTS, there are no further subcategories to introduce. Classification within 3809.93.10.00 is therefore determined by the intended use in the textile, paper, or leather industries, and the crucial chemical composition test of containing 5 percent or more by weight of aromatic or modified aromatic substances.
