9902.02.34 - 2,5,8,11,14,17,20-Heptaoxadocosan-22-ol methanesulfonate (CAS No. 477775-57-8) (provided for in subheading 2909.19.60).

This HTS category, 9902.02.34, covers a specific chemical compound: 2,5,8,11,14,17,20-Heptaoxadocosan-22-ol methanesulfonate, identified by CAS number 477775-57-8. This classification falls under Chapter 99, which pertains to temporary legislation, temporary modifications proclaimed pursuant to trade agreements, and additional import restrictions proclaimed pursuant to Section 22 of the Agricultural Adjustment Act. The inclusion of "provided for in subheading 2909.19.60" indicates that this specific compound, despite its presence in Chapter 99, is primarily recognized and potentially falls under the ether classification within Chapter 29 for regular tariff purposes.

As a leaf node within Chapter 99, this category does not have further subcategories. Its purpose is to track specific, often temporary, import provisions for this particular chemical. The distinction from other entries in Chapter 99 would lie in the unique chemical identity of 2,5,8,11,14,17,20-Heptaoxadocosan-22-ol methanesulfonate and the specific trade agreement or legislative action that has led to its inclusion in this temporary provision. Unlike the broad product categories found in earlier chapters of the HTS (e.g., live animals in Chapter 01), this entry focuses on a precisely defined chemical substance subject to special import regulations.
