3814.00.10.00 - Containing 5 percent or more but not more than 25 percent by weight of one or more aromatic or modified aromatic substances

This HTS classification, 3814.00.10.00, encompasses organic composite solvents and thinners that are not specified elsewhere and are specifically formulated to contain between 5 percent and 25 percent, by weight, of one or more aromatic or modified aromatic substances. These products are designed to dissolve or dilute other substances, commonly used in the preparation, application, or removal of paints, varnishes, and other coatings. The precise percentage of aromatic content is the key determinant for classification within this sub-heading.

It is crucial to distinguish this category from its sibling, 3814.00.20.00, which covers similar composite solvents and thinners but with a higher concentration of aromatic or modified aromatic substances, exceeding 25 percent by weight. Therefore, the primary differentiating factor is the measured aromatic content. The residual category, 3814.00.50, serves as a catch-all for any other composite solvents and thinners that do not meet the specific aromatic content criteria of the preceding subheadings within 3814.00.

As this is a leaf node within the HTS structure, there are no further subcategories to introduce. Classification is finalized at this level based on the composition of the organic composite solvent or thinner, specifically the weight percentage of aromatic or modified aromatic substances present. For practical classification purposes, an accurate chemical analysis to determine this percentage is essential.
