9902.06.81 - 2-[(2RS)-2-(1-Chlorocyclopropyl)-3-(2-chlorophenyl)-2-hydrox- ypropyl]-2H-1,2,4-triazole-3(4H)-thione (Prothioconazole) (CAS No. 178928-70-6)(provided for in subheading 2933.99.22)

This HTS category, 9902.06.81, specifically covers the fungicide known as Prothioconazole (CAS No. 178928-70-6). While its primary chemical classification falls under subheading 2933.99.22, this particular 9902 code signifies a temporary legislative provision or modification related to its import. Such provisions within Chapter 99 are typically enacted for specific policy objectives, trade agreement implementations, or to impose temporary import restrictions, often related to agricultural protection as outlined in Section 22 of the Agricultural Adjustment Act.

Unlike the broad categories of live animals found in the early chapters of the HTS (e.g., 0101 for horses, 0102 for bovine animals), this entry is highly specialized. It pertains to a specific chemical compound used in agriculture, not live organisms. The distinction from other Chapter 99 subheadings would lie in the specific commodity or provision it addresses. For instance, other 9900 series codes might cover temporary quotas on agricultural products, duty suspensions for specific industrial goods, or preferential tariff treatment under trade agreements, none of which are directly applicable to the classification of Prothioconazole under this specific code.

As a leaf node within the HTS database, HTS code 9902.06.81 does not have further subcategories. Its classification is definitive for Prothioconazole when imported under the specific temporary legislative or trade agreement provision it represents. Importers must therefore ensure that the reason for the importation aligns with the purpose of this 9902 code.
