HTS Code 9902.03.81 pertains to 1,3-Benzenediamine, also identified by its CAS Number 108-45-2. This classification falls under Chapter 99, which covers temporary legislation, trade agreement modifications, and specific import restrictions. The description explicitly notes that this substance is provided for under subheading 2921.51.10, indicating its primary classification as an aromatic diamine.

This temporary or special classification for 1,3-Benzenediamine is distinct from the general provisions found in earlier chapters of the HTS. Unlike sibling categories which typically cover broad classes of goods such as live animals (e.g., 0101-0105) or various agricultural products, HTS 9902.03.81 is a very specific designation. Its purpose is to apply particular trade policies or restrictions to this single chemical compound, rather than classifying it based on its inherent physical or material properties as a general commodity.

As a leaf node within the HTS database, HTS Code 9902.03.81 does not have further subcategories. This signifies that all imports of 1,3-Benzenediamine falling under this specific temporary provision will be classified directly under this code. Any variations in its form, purity, or intended use are not separately classified at this level, and importers must adhere to the specific requirements or restrictions associated with this temporary classification in addition to any base classification under Chapter 29.
