9902.09.83 - Formulated fungicide kit consisting of individual packs of tetra-n-butylammonium fluoride (CAS No. 87749-50-6), dimethylsulfoxide (CAS No. 67-68-5), 2-(butyldimethylsilyl)-1-methylcyclopropanol-1-methanesulfonate (CAS No. 1446996-86-6), and sodium hydroxide solution (CAS No. 1310-73-2) (provided for in subheading 3808.92.50)

This HTS category, 9902.09.83, specifically covers a formulated fungicide kit. The kit comprises individual, pre-measured packs of distinct chemical components: tetra-n-butylammonium fluoride (CAS No. 87749-50-6), dimethylsulfoxide (CAS No. 67-68-5), 2-(butyldimethylsilyl)-1-methylcyclopropanol-1-methanesulfonate (CAS No. 1446996-86-6), and sodium hydroxide solution (CAS No. 1310-73-2). The critical element for classification here is the composite nature of the product as a ready-to-use kit intended for fungicidal application, even though its individual components are provided for under a different subheading (3808.92.50).

As this is a leaf node, there are no subcategories to introduce. The classification is highly specific to this exact formulation and its intended use as a fungicide kit. Unlike its sibling categories which encompass a vast array of live animals, this entry is situated within Chapter 99, indicating it falls under temporary legislation or special provisions. Therefore, it does not directly compare to the broader categories of live animals but rather to other specific, temporary, or specially regulated items within Chapter 99. The distinguishing factor remains the precise composition and function of this chemical kit.
