Overview

This HTS category, 9902.01.22, specifically covers Nitrosylsulfuric acid, identified by CAS Number 7782-78-7. It is important to note that this entry is provided for classification purposes within subheading 2811.19.61, indicating its primary classification under Chapter 28, which deals with inorganic chemicals. However, this specific 9902 code signifies a temporary modification or special provision, likely related to trade agreements or agricultural import restrictions as indicated by its placement in Section XXII.

Unlike the numerous sibling categories at the top level of the HTS database, which predominantly cover live animals and agricultural products, this node is highly specialized. Its existence within Chapter 99 signals a deviation from standard commodity classifications. The focus here is not on broad categories of goods but on a specific chemical compound subject to particular import regulations or tariff treatments.

As a leaf node, HTS 9902.01.22 does not have further subdivisions. Therefore, classification within this code depends directly on the identification of Nitrosylsulfuric acid itself. Importers and customs brokers must ensure that the goods being declared precisely match the chemical identity and CAS number specified. Any product that is not Nitrosylsulfuric acid, even if it shares some chemical similarities or is used in related industrial processes, would need to be classified under its appropriate, standard HTS code, likely within Chapter 28 or another relevant chapter depending on its composition and intended use.
