9902.03.71 - o-Toluidine (CAS No. 95-53-4) (provided for in subheading 2921.43.90)

This HTS category, 9902.03.71, specifically addresses importations of o-Toluidine, identified by CAS Number 95-53-4. This compound is a primary aromatic amine derived from toluene. While o-Toluidine is recognized for its use as an intermediate in the production of dyes, pigments, agricultural chemicals, and pharmaceuticals, its classification under Chapter 99 signifies a temporary modification or restriction on its import. It's crucial to note that this classification is provided for reference within subheading 2921.43.90, which covers other aromatic amines.

Unlike the broad categories of live animals or other general commodity headings found at the HTS database root, this category is highly specific. It doesn't cover other chemical compounds or broader classes of organic chemicals. The "99" series chapters in the HTS are reserved for temporary legislation, modifications pursuant to trade agreements, and specific import restrictions under Section 22 of the Agricultural Adjustment Act. Therefore, this classification is not based on the inherent physical or chemical properties in the same way as primary HTS chapters, but rather on specific trade or agricultural policy measures.

As a leaf node within the HTS database, category 9902.03.71 has no further subcategories. This means that any importation of o-Toluidine that meets the conditions for this temporary legislation will be classified directly under this code. Importers must consult the specific regulations or proclamations associated with this 9902 code to understand any applicable quotas, duties, or other requirements beyond the standard classification under subheading 2921.43.90.
