9902.06.17 - 3-Dodecyl-1-(2,2,6,6-tetramethyl-4-piperidinyl)-2,5-pyr- rolidinedione (CAS No. 79720-19-7) (provided for in subheading 2933.39.61)

This HTS category, 9902.06.17, designates a specific chemical compound: 3-Dodecyl-1-(2,2,6,6-tetramethyl-4-piperidinyl)-2,5-pyrrolidinedione, also identified by its CAS Number 79720-19-7. This entry is part of Chapter 99, which encompasses temporary legislation and modifications related to trade agreements and import restrictions. The inclusion of the parenthetical reference to subheading 2933.39.61 indicates that this item is being classified under a special provision, likely due to specific import limitations or tariff treatments.

As a leaf node within Chapter 99, this category does not have further subcategories. Its purpose is to track and manage the import of this particular chemical compound under a distinct set of rules or duties separate from its standard classification within the main body of the HTS. This allows for targeted control over specific goods that may be subject to temporary quotas, special tariff rates, or other trade policy measures.

The distinction of this category from its sibling HTS codes (such as those for live animals in Chapter 01) lies in its placement within Chapter 99. While the primary HTS chapters classify goods by their nature and intended use, Chapter 99 is reserved for administrative and legislative provisions that override or supplement the standard classifications. Therefore, 9902.06.17 does not describe a product type in the same way as goods in Chapters 1-97, but rather signifies a special import status for a precisely identified chemical.
