9902.02.57 - 1,3-Cyclohexanedione (CAS No. 504-02-9) (provided for in subheading 2914.29.50)

This HTS category, 9902.02.57, specifically covers 1,3-Cyclohexanedione, identified by its CAS Number 504-02-9. This chemical compound is temporarily classified under this provision, with its primary classification found in subheading 2914.29.50, which pertains to other cyclic ketones. The presence of 1,3-Cyclohexanedione in Chapter 99 signifies a temporary modification or restriction on its import, often related to trade agreements or specific agricultural adjustment programs.

Given that this is a leaf node within the HTS structure for Chapter 99, there are no further subcategories. Therefore, the focus is on the specific conditions and purposes that necessitate its classification here. Unlike the broad categories found in earlier chapters of the HTS (such as live animals in Chapter 01), this provision deals with a precisely defined chemical substance subject to specific trade policy measures. The distinction lies in the nature of the goods themselves and the regulatory framework governing their entry into the United States, which is distinctly different from the general commodity classifications of earlier chapters.
