9902.09.50 - Product mixtures containing 2-[(2RS)-2-(1-chlorocyclopropyl)-3-(2-chlorophenyl) -2-hydroxypropyl]-2H-1,2,4-triazole-3 (4H)-thione (Prothioconazole) (CAS No. 178928-70-6) and (RS)-1-p-chlorophenyl-4,4-dimethyl-3-(1H-1,2,4-triazol-1-ylmethyl) pentan-3-ol (Tebuconazole) (CAS No. 107534-96-3) (provided for in subheading 3808.92.15)

This HTS category, 9902.09.50, covers specific product mixtures primarily composed of two fungicidal active ingredients: Prothioconazole and Tebuconazole. These are not raw materials but formulated products intended for use in agricultural or horticultural applications to control fungal diseases. The inclusion of specific chemical names and CAS numbers signifies a precise definition of the mixture's active components for classification purposes.

Unlike the general agricultural and animal products found in the earlier chapters of the HTS, such as live animals (Chapters 1-4) or even general chemical products that might be listed in Chapter 38, this category is highly specialized. It sits within Chapter 99, which designates temporary legislation and special provisions. This means its existence and tariff treatment are likely time-limited or subject to specific trade policies, distinguishing it from permanent classifications for standard chemical compounds.

As a leaf node, HTS 9902.09.50 does not have subcategories. Classification within this code is determined by the presence and concentration of Prothioconazole and Tebuconazole within the mixture, and the fact that it falls under the temporary or special provisions outlined in Chapter 99. Its parentage within Section XXII, specifically under temporary legislation and modifications, underscores its distinct regulatory status and potential for differing tariff rates or import conditions compared to standard chemical classifications under Chapter 38.
