9902.02.12 - Magnesium bis(2-methyl-2-propanolate) (Magenesium tert-butoxide) (CAS No. 32149-57-8) (provided for in subheading 2905.19.90)

This HTS code, 9902.02.12, specifically classifies Magnesium bis(2-methyl-2-propanolate), also known as Magnesium tert-butoxide (CAS No. 32149-57-8). This compound is provided for under subheading 2905.19.90 within the main HTS structure, indicating its nature as an organic chemical. The classification within Chapter 99 signifies that this particular entry is subject to temporary legislation or modifications. This could include temporary duty rates, quantitative restrictions, or other special provisions enacted for policy or trade agreement purposes.

Distinguishing this entry from its sibling categories, which are found throughout the HTS, is crucial. Unlike general merchandise classifications covering raw materials, finished goods, or agricultural products (represented by the extensive list of initial sibling categories like live animals), this code is for a highly specific chemical compound. Its placement within Section XXII and Chapter 99 highlights its distinct treatment, separate from the standard product-based classifications that form the bulk of the HTS. The focus here is not on the general nature of the goods but on their specific chemical identity and the temporary legislative or trade provisions that apply.

As this is a leaf node, there are no further subcategories to explore. The classification concludes at this level, meaning any importation of Magnesium tert-butoxide subject to the provisions of this code would be classified directly under 9902.02.12. Importers and customs brokers should consult the specific temporary legislation or proclamations associated with this HTS code to understand the exact requirements and duty implications.
