9902.03.44 - Bis(4-t-butylcyclohexyl)peroxydicarbonate (CAS No. 15520-11-3) (provided for in subheading 2920.90.51)

This HTS category, 9902.03.44, specifically covers Bis(4-t-butylcyclohexyl)peroxydicarbonate, identified by CAS No. 15520-11-3. This compound is classified under Section XXII, which pertains to Special Classification Provisions, Temporary Legislation, and Modifications related to trade agreements and agricultural adjustments. Its presence in Chapter 99 signifies a unique classification status, often indicating temporary measures or specific import restrictions rather than standard commodity classification.

Unlike the broad scope of sibling categories within the HTS, which typically cover general merchandise, live animals, or raw materials, this category is highly specific. Its focus on a particular chemical compound, Bis(4-t-butylcyclohexyl)peroxydicarbonate, sets it apart from general chemical classifications found in earlier chapters. This specialized designation suggests that its import is subject to particular regulations or considerations beyond standard tariff rates, likely due to its intended use or the conditions of its temporary inclusion.

As this is a leaf node, there are no further subcategories. Classification within 9902.03.44 is definitive for Bis(4-t-butylcyclohexyl)peroxydicarbonate. The explicit mention of its provision under subheading 2920.90.51 provides critical context, indicating that while this compound is recognized under the general chemical provisions, its current classification under Chapter 99 signifies a temporary or otherwise special trade status. Importers must ensure strict adherence to any accompanying documentation and regulations associated with this specific temporary tariff provision.
