9902.04.83 - 4-[(4-Aminophenyl)azo]-benzenesulfonic acid (CAS No. 104-23-4) (provided for in subheading 2927.00.50)

This HTS classification, 9902.04.83, specifically covers 4-[(4-Aminophenyl)azo]-benzenesulfonic acid, also identified by CAS Number 104-23-4. This chemical compound is a dyestuff intermediate, characterized by its azo group and sulfonic acid functionality, which is recognized under subheading 2927.00.50 of the HTS. The inclusion of this item within Chapter 99 signifies its presence under temporary legislation, temporary modifications related to trade agreements, or additional import restrictions imposed under Section 22 of the Agricultural Adjustment Act.

As a specific entry within Chapter 99, this classification is distinct from the broader categories of goods found elsewhere in the HTS, such as live animals listed in Chapter 01. While Chapter 99 generally deals with temporary measures, the specific product code 9902.04.83 targets a particular chemical substance for import control or duty purposes. Its presence here indicates a specific regulatory treatment outside of its primary chemical classification.

Since this is a leaf node, there are no further subcategories within 9902.04.83. Therefore, classification under this code relies solely on the accurate identification of the imported merchandise as 4-[(4-Aminophenyl)azo]-benzenesulfonic acid, with its CAS number serving as a key identifier. Importers must ensure their declarations precisely match this description to comply with the provisions of Chapter 99.
