9902.03.82 - N-Phenyl-p-phenylenediamine (CAS No. 101-54-2) (provided for in subheading 2921.51.50)

This HTS category, 9902.03.82, specifically addresses the importation of N-Phenyl-p-phenylenediamine, identified by CAS Number 101-54-2. While this chemical compound is fundamentally classified under subheading 2921.51.50, its appearance within Chapter 99 signifies a temporary legislative measure or a modification related to trade agreements or agricultural adjustment provisions. This indicates that while the commodity itself is a defined chemical substance, its import is subject to special, potentially time-limited, conditions or restrictions beyond its standard tariff classification.

As a leaf node within Chapter 99, this category does not have further subdivisions. Its purpose is to isolate and manage the specific import of N-Phenyl-p-phenylenediamine under distinct regulatory frameworks. Therefore, any classification of this substance requires not only adherence to its primary chemical classification but also careful consideration of any accompanying temporary provisions denoted by this Chapter 99 subheading. The existence of this code suggests that its use might be for purposes such as domestic production support, anti-dumping measures, or other trade policy objectives that necessitate separate monitoring and control.
