Overview
This HTS category, 9902.06.44, specifically covers the chemical compound known as (RS)-2′-[(4,6-dimethoxypyrimidin-2-yl)(hydroxy)methyl]-1,1-difluoro-6′-(methoxymethyl)methanesulfonanilide, also identified by its common name, Pyrimisulfan, and CAS Registry Number 221205-90-9. This classification is part of Chapter 99, which deals with temporary legislation and special provisions, indicating that this specific item is subject to unique import rules or modifications that are not part of the standard Harmonized Tariff Schedule. The description further notes that this substance is "provided for in subheading 2933.59.80," meaning its primary tariff classification falls under that subheading, but its presence here in Chapter 99 signifies a special treatment or restriction.
Distinguishing this category from its sibling categories within the broader HTS framework is crucial. While sibling categories in HTS Chapter 99 would generally also represent temporary or specific legislative provisions affecting various goods, the specificity of 9902.06.44 to Pyrimisulfan sets it apart. Unlike broader categories that might cover general agricultural products or manufactured goods, this node is dedicated to a single, precisely defined chemical compound. Its unique designation highlights that Pyrimisulfan, despite its base classification under Chapter 29 (which covers organic chemicals), is subject to particular temporary tariff or import regulations.
As this is a leaf node, there are no further subcategories to introduce. Classification under 9902.06.44 is final for this specific item. Any importer or exporter dealing with Pyrimisulfan must adhere to the specific regulations or duty rates stipulated under this HTS code, in addition to its principal classification under subheading 2933.59.80. This serves as a reminder that Chapter 99 codes are dynamic and often reflect trade agreements, retaliatory measures, or specific policy objectives impacting the import of particular goods.
