9902.10.29 - Plasticizers containing diphenyl cresyl phosphate (CAS No. 26444-49-5), triphenyl phosphate (CAS No. 115-86-6), tricresyl phosphate (CAS No. 1330-78-5), and phenyl dicresyl phosphate (CAS No. 26446-73-1) (provided for in subheading 3812.20.10)

This HTS category, 9902.10.29, specifically covers certain plasticizers identified by their chemical composition. These plasticizers are characterized by the presence of specific organophosphate compounds: diphenyl cresyl phosphate (CAS No. 26444-49-5), triphenyl phosphate (CAS No. 115-86-6), tricresyl phosphate (CAS No. 1330-78-5), and phenyl dicresyl phosphate (CAS No. 26446-73-1). The classification notes that these substances are also provided for in subheading 3812.20.10, indicating a potential overlap or specific application within the broader chemical provisions.

As a specific provision under Chapter 99, which deals with temporary legislation and modifications, this category functions to temporarily regulate or identify these particular plasticizers for import purposes, often due to trade agreements or specific policy measures. Unlike the broad categories of live animals or agricultural products found at the beginning of the HTS, this provision focuses on a niche industrial chemical used in manufacturing. Its placement within Chapter 99 underscores its distinction from permanent classifications found in earlier chapters, suggesting its application is subject to change.

Given that 9902.10.29 is a leaf node, there are no further subcategories to explore. This means that any import meeting the precise chemical composition criteria as described will fall directly under this specific provision. The primary classification criterion is the definitive presence of the listed organophosphate compounds within the plasticizer.
