2917.33.00.10 - Diisodecyl orthophthalate

This classification covers diisodecyl orthophthalate, a specific type of aromatic ester derived from orthophthalic acid. These compounds are characterized by the presence of two isodecyl ester groups attached to the orthophthalate nucleus. Diisodecyl orthophthalate is primarily utilized as a plasticizer, imparting flexibility and durability to various polymer applications, particularly in the formulation of polyvinyl chloride (PVC) products.

Within the broader category of aromatic polycarboxylic acids and their derivatives, this HTS code specifically isolates diisodecyl orthophthalate. It is distinguished from its sibling category, 2917.33.00.50, which encompasses "Other" dinonyl or didecyl orthophthalates. Therefore, goods classified under 2917.33.00.10 must be specifically identified as diisodecyl orthophthalate, differentiating them from other orthophthalates with different alkyl ester chains or variations within the dinonyl/didecyl designation.

As this is a leaf node, there are no further subdivisions within this HTS code. Classification at this level requires a precise identification of the chemical substance as diisodecyl orthophthalate, based on its chemical structure and intended commercial use as a plasticizer or similar additive in industrial processes.
