9902.06.18 - 1-(1-Acetyl-2,2,6,6-tetramethyl-4-piperidinyl)-3-dodecyl- 2,5-pyrrolidinedione (CAS No. 106917-31-1) (provided for in subheading 2933.39.61)

This HTS category, 9902.06.18, specifically classifies the chemical compound 1-(1-Acetyl-2,2,6,6-tetramethyl-4-piperidinyl)-3-dodecyl-2,5-pyrrolidinedione, identified by CAS Number 106917-31-1. This is a temporary classification provision, designated for specific import restrictions or modifications under trade agreements or Section 22 of the Agricultural Adjustment Act. The primary purpose of this code is to track and potentially control the importation of this particular chemical, which is provided for in subheading 2933.39.61 of the permanent tariff schedule.

As a leaf node within Chapter 99, this category does not have further subdivisions. Its placement within Section XXII signifies its exceptional nature, distinct from the standard goods classified under Chapters 1 through 98. Unlike the broad categories of live animals in sibling categories like 0101 (Live horses) or 0102 (Live bovine animals), this code pertains to a highly specific synthetic organic chemical, not live agricultural products. The existence of this temporary classification suggests a unique regulatory consideration for this compound that warrants separate tracking beyond its primary tariff heading.
