9902.07.52 - 5-Ethoxy-3-(trichloromethyl)-1,2,4-thiadiazole (Etridiazole) (CAS No. 2593-15-9) (provided for in subheading 2934.99.90)

This HTS category, 9902.07.52, covers the specific chemical compound 5-Ethoxy-3-(trichloromethyl)-1,2,4-thiadiazole, also known as Etridiazole. This substance is identified by its CAS number 2593-15-9 and is primarily recognized for its use as a fungicide. The classification within Chapter 99 indicates that this is a temporary provision, likely relating to special trade agreements, temporary modifications, or specific import restrictions proclaimed under relevant legislation, such as Section 22 of the Agricultural Adjustment Act.

As a specific chemical provision within the temporary legislation chapter, this category is distinct from the broader, more general classifications found in earlier chapters of the HTS. Unlike sibling categories that might cover live animals or basic agricultural products, 9902.07.52 is dedicated to a single, complex organic chemical with a defined industrial or agricultural application. Its placement within Chapter 99 signifies that its tariff treatment or import status is subject to specific, time-limited governmental actions, which may differ significantly from standard tariff rates applied to chemicals classified under Chapter 29.

This node represents a leaf node within the HTS structure, meaning there are no further subcategories branching from this specific code. Consequently, the classification for Etridiazole will be directly determined by its presence under 9902.07.52. Importers should carefully consult the specific legislative proclamations or trade agreements associated with this provision to understand any duties, quotas, or other regulatory requirements that may apply to its importation.
