Overview
This HTS category, 9902.02.56, specifically designates 3-Methyl-4-(2,6,6-trimethylcyclohex-2-enyl)but-3-en-2-one, commonly known as Methylionone (CAS No. 1335-46-2). This classification applies to this particular chemical compound, which is often used as a fragrance ingredient in perfumes and other scented products.
As a specialized subheading within Chapter 99, this category serves to implement temporary legislation or specific trade agreement provisions related to this identified chemical. It is crucial to note that while the description provides a CAS number for precise identification, the primary classification relies on the chemical name and its specific structure.
This subheading is distinct from the broader categories within Section XXII, which cover a wide range of temporary import restrictions and trade agreement modifications. Within Chapter 99, 9902.02.56 is a leaf node, meaning it does not have further subdivisions. Its purpose is to isolate and manage the importation of this specific Methylionone under particular trade conditions, differentiating it from other temporary measures applied to different goods. The classification is strictly for this chemical and does not extend to mixtures or formulations where it may be a component, which would be classified elsewhere.
