Overview
This category, HTS 9902.05.60, specifically covers 6-Isopropyl-9-methyl-1,4-dioxaspiro[4.5]decane-2-methanol, also known as Menthone glyceryl ketal. This particular compound, identified by CAS No. 63187-91-7, is subject to special classification provisions and is provided for under subheading 2932.99.90, indicating it is a cyclic acetal derived from menthone and glycerol. Its inclusion within Chapter 99 signifies that it falls under temporary legislation, temporary modifications to trade agreements, or additional import restrictions enacted under specific agricultural legislation.
As a leaf node within the HTS database, this category does not possess further subdivisions. Its purpose is to isolate and manage the tariff treatment of this specific chemical compound, distinguishing it from other goods that might otherwise fall under broader chemical classifications. The special provisions applied here necessitate a direct classification under 9902.05.60 for accurate customs processing, rather than being subsumed into more general headings found in earlier chapters of the HTS. The context of Section XXII emphasizes that this classification is governed by special, often temporary, legal frameworks, rather than the standard permanent tariff structure.
