9902.08.84 - 2,2'-Thiene-2,5-diylbis(5-tert-butyl-1,3-benzoxazole) (CAS No. 7128-64-5) (provided for in subheading 3204.20.80)

This HTS code, 9902.08.84, designates a specific chemical compound known as 2,2'-Thiene-2,5-diylbis(5-tert-butyl-1,3-benzoxazole), identified by CAS No. 7128-64-5. This compound falls under the provisions of Chapter 99, which encompasses temporary legislation and special classification provisions. Specifically, it is provided for within subheading 3204.20.80, indicating its underlying classification relates to synthetic organic coloring matter. The inclusion within Chapter 99 signifies a temporary modification or special treatment applicable to this particular substance.

Unlike the broader categories of live animals found at the beginning of the HTS (e.g., 0101 through 0105), this entry pertains to a manufactured chemical product with a defined molecular structure. Its placement within Chapter 99 highlights that its tariff treatment, while referencing a specific material classification (3204.20.80), is subject to temporary legislative measures rather than its fundamental material composition alone. This distinguishes it from general provisions for chemicals or dyes that do not carry such temporary designations.

As this is a leaf node, there are no further subcategories within 9902.08.84. The classification is highly specific to the compound identified by name and CAS number. Therefore, classification under this code is determined by the precise identification of the imported article matching the description. The "provided for in subheading 3204.20.80" clause serves to anchor this temporary classification to its principal heading within the permanent HTS structure, guiding further tariff considerations.
