9902.10.34 - Preparations containing tetrakis[2,4-bis(2-methyl-2-propanyl)phenyl] 4,4'-biphenyldiylbis(phosphonite) (CAS No. 119345-01-6) (provided for in subheading 3812.39.60)

This HTS category, 9902.10.34, specifically covers preparations containing tetrakis[2,4-bis(2-methyl-2-propanyl)phenyl] 4,4'-biphenyldiylbis(phosphonite), identified by CAS No. 119345-01-6. These specialized chemical preparations are classified under this temporary provision because their primary tariff treatment is dictated by a specific subheading within Chapter 38, namely 3812.39.60, which pertains to anti-oxidants and anti-ozonants, and other stabilizers for plastics and rubber. The purpose of this 9902 code is to apply unique tariff modifications or restrictions to this particular chemical compound, as proclaimed under trade agreements or other specific legislative authorities.

As this is a leaf node within Chapter 99, there are no further subcategories. The classification is highly specific, targeting a single chemical preparation based on its precise chemical name and CAS number. It is crucial to distinguish this entry from general chemical classifications by recognizing that its presence in Chapter 99 signifies a departure from standard tariff treatment. While other chemical substances might fall under broader headings in Chapter 38 or other sections of the HTS, this specific phosphonite preparation is singled out for distinct treatment due to reasons stipulated in the relevant trade legislation. Therefore, classification hinges on the exact identification of the chemical compound and verification of its inclusion within this particular temporary provision.
