Overview

This HTS category, 9902.09.84, specifically addresses mixtures that contain 5-methyl-1,2-oxazol-3(2H)-one, more commonly known as Hymexazol. While Hymexazol itself might fall under other HTS classifications based on its primary use (e.g., as a fungicide under 3808.92.50), this particular code is designated for mixtures where Hymexazol is a component. These mixtures are likely intended for agricultural or industrial applications, where the properties of Hymexazol are utilized. The inclusion of this code within Chapter 99 signifies its status as a temporary measure or a specific provision for these mixtures.

As a category within Chapter 99, this code stands apart from the broad, systematic classifications found in Chapters 1 through 97. Its siblings, such as live animals (e.g., 0101, 0102), are fundamentally different in their nature and purpose. This 9900 series code is not concerned with the classification of basic commodities or manufactured goods based on their material composition or end-use in the typical sense. Instead, it operates under special provisions, often related to temporary trade agreements, quotas, or specific import restrictions, making its context distinct from the general product categories.

Since HTS code 9902.09.84 is a leaf node, it has no further subcategories. This means that any product meeting the description of a mixture containing Hymexazol is directly classified under this code. The crucial determinant for classification here is the presence of Hymexazol within the mixture, overriding other potential classifications of the mixture's other components or its overall intended use, within the context of these special provisions. Classification professionals will need to verify the chemical composition and ensure the mixture indeed contains 5-methyl-1,2-oxazol-3(2H)-one to correctly apply this code.
