3824.99.26.00 - Benzene, 2,4-diisocyanate-1,3,5-tris(1- methylethyl) homopolymer; 5-Fluoro-2-methyl-1-[[4-(methylsulfinyl)- phenyl]methylene]-1H-indene;Mixtures of dimethyl phthalate, t-butanol, hydrogen peroxide, and sodium salicylate; andMixtures containing derivatives of N-[4-(2- hydroxy-3-phenoxypropoxy)phenyl]- acetamide

This HTS classification, 3824.99.26.00, encompasses a diverse range of specific chemical products and mixtures not elsewhere specified or included. Primarily, it covers several distinct preparations, including the homopolymer of benzene, 2,4-diisocyanate-1,3,5-tris(1-methylethyl), and the indene derivative 5-Fluoro-2-methyl-1-[[4-(methylsulfinyl)-phenyl]methylene]-1H-indene. Additionally, this code includes specific mixtures such as those containing dimethyl phthalate, t-butanol, hydrogen peroxide, and sodium salicylate, as well as mixtures comprising derivatives of N-[4-(2-hydroxy-3-phenoxypropoxy)phenyl]-acetamide.

Distinguishing this category from its siblings, 3824.99.21.00 pertains exclusively to substances naturally found in coal tar. Furthermore, 3824.99.25.00 is reserved for specific aqueous mixtures of triphenyl sulfonium chloride, diphenyl (4-phenylthio)phenyl sulfonium chloride, and (thiodi-4,1-phenylene)bis(diphenyl sulfonium) dichloride. The remaining sibling category, 3824.99.29.00, covers "Other" preparations not fitting the specific descriptions of the other subheadings within the "Mixtures containing 5 percent or more by weight of one or more aromatic or modified aromatic substances" group.

As a leaf node within the HTS, 3824.99.26.00 represents the most granular classification for these particular chemical products and mixtures. Therefore, there are no further subcategories to introduce. Classification into this code relies on the precise identification of the listed chemical compounds and mixtures, ensuring they meet the criteria outlined in the description and do not fall under any more specific or encompassing HTS provisions.
