9902.10.72 - alpha-Alkenes (C20 -C24) maleic anhydride-4-amino-2,2,6,6-tetramethylpiperidine, polymer (CAS No. 152261-33-1) (provided for in subheading 3902.90.00)

This HTS classification pertains to a specific polymer, identified by its chemical composition: alpha-Alkenes (C20-C24) reacted with maleic anhydride and 4-amino-2,2,6,6-tetramethylpiperidine. The CAS number 152261-33-1 further specifies this unique chemical compound. While the primary HTS code resides within Chapter 99, reflecting temporary legislation and specific import restrictions, its underlying classification is provided for in subheading 3902.90.00, which generally covers other polymers of olefins, in primary forms, not elsewhere specified or included.

Distinguishing this category from its sibling categories at the HTS Database Root level is crucial. The sibling categories presented, such as "Live horses, asses, mules and hinnies" (0101) and "Live bovine animals" (0102), fall under entirely different chapters and relate to live animals. This node, however, deals with a manufactured chemical product, a specific polymer, not living organisms. The presence of the Chapter 99 code indicates this polymer is subject to particular temporary trade provisions or restrictions, setting it apart from general classifications of similar polymers that might be found under Chapter 39 without such supplementary codes.

As this node is a leaf node, it does not have further subcategories. Therefore, the focus for classification within this specific entry is on accurately identifying the polymer based on its described chemical structure and CAS number, and understanding the implications of its inclusion under Chapter 99, which dictates any special import requirements, duties, or quantitative limitations that may be in effect.
