This HTS classification, 9902.08.04, specifically covers certain mixtures of disperse dyes. These dyes are primarily used for coloring synthetic fibers, particularly polyester, and are characterized by their low water solubility and ability to diffuse into the fiber under specific conditions. The detailed chemical names and CAS numbers provided for Disperse Yellow 163, Disperse Red 167:1, Disperse Red 60, Disperse Blue 77, Disperse Blue 56, Disperse Blue 214 E, and Disperse Blue 214 EE are crucial for precise identification within this category.

As a temporary classification under Chapter 99, this heading is distinct from the permanent classifications found in Chapters 1-98. While other sections of the HTS might classify dyes based on their chemical composition or end-use in a more general manner (e.g., Chapter 32 for dyes and pigments), 9902.08.04 represents a specific, temporary provision. This means that goods classified here are subject to special rules or restrictions that differ from their general HTS classification, which is indicated as being under subheading 3204.11.35. The temporary nature of this classification signifies that it is likely tied to specific trade policies, agreements, or temporary import restrictions, rather than being a permanent product category.

Since this is a leaf node in the HTS database, there are no further subcategories that subdivide this classification. The description itself is highly specific, encompassing defined mixtures of particular disperse dyes. Therefore, the focus for classification under 9902.08.04 is on confirming that the imported product is indeed a mixture containing the specified dyes and falls under the temporary legislative provisions indicated by Chapter 99.
