9902.06.77 - [α-(4-Chlorophenyl)-α-(1-cyclopropylethyl)-1H-1-1,2,4- triazole-1-ethanol (Cyproconazole) (CAS No. 94361-06-5) (provided for in subheading 2933.99.22)

This HTS category, 9902.06.77, specifically covers the chemical compound Cyproconazole, identified by CAS No. 94361-06-5. Cyproconazole is a triazole fungicide used as a plant protection product. It functions by inhibiting sterol biosynthesis in fungi, making it effective against a range of fungal diseases in agriculture. The provision of this specific tariff number indicates that the importation of Cyproconazole may be subject to special administrative or regulatory requirements.

As a leaf node within Chapter 99, this category is highly specific. Its "siblings" at the Chapter 99 level, such as other temporary legislation or trade agreement modifications, would cover entirely different sets of goods or circumstances. Unlike the broad agricultural and live animal classifications found in earlier chapters of the HTS (e.g., Chapter 01), 9902.06.77 deals with a single, defined chemical substance with a particular agricultural application. The parent context of Section XXII further underscores that this classification is not based on the inherent physical characteristics of the good alone but is governed by temporary or specific legislative provisions.

Since this is a leaf node, there are no further subcategories. The classification is precise and intended to apply directly to Cyproconazole when imported under the conditions outlined by its inclusion in Chapter 99. Importers should consult the specific legislation or proclamations associated with this HTS code to understand any applicable duties, restrictions, or documentation requirements beyond the standard customs procedures.
