9902.02.01 - p-Toluenesulfonic acid (4-methylbenzenesulfonic acid hydrate (1:1)) (CAS No. 6192-52-5) (provided for in subheading 2904.10.37)

This HTS code, 9902.02.01, specifically designates p-Toluenesulfonic acid, also known as 4-methylbenzenesulfonic acid hydrate (1:1) with CAS Number 6192-52-5. It is important to note that while classified under Chapter 99, which pertains to temporary legislation and special provisions, the acid itself is provided for in subheading 2904.10.37 under the main HTS structure. This temporary classification signifies that its import may be subject to specific, potentially time-limited, regulations or restrictions.

The primary purpose of this classification is to track and potentially regulate the importation of this particular chemical compound. Unlike sibling categories within Chapter 99, which might cover other temporary trade agreement modifications or agricultural import restrictions, this node is narrowly focused on a single chemical substance. Its existence under Chapter 99 means that its import status could differ from its standard classification under Chapter 29, which deals with organic chemicals.

As a leaf node, HTS code 9902.02.01 does not have any further subcategories. This indicates that all imports of p-Toluenesulfonic acid (4-methylbenzenesulfonic acid hydrate (1:1)) that fall under this temporary classification provision will be directly handled at this level. Classification within this code relies solely on the accurate identification of the chemical substance itself, as confirmed by its chemical name, CAS number, and the fact that it is imported under the specific temporary provision outlined in Chapter 99.
