View full HS code details

Dioctyl phthalate (DOP), also commonly referred to as bis(2-ethylhexyl) phthalate (DEHP), is classified under HS code 2917.32. This classification is based on its identity as an aromatic polycarboxylic acid derivative. Specifically, it is an ester of orthophthalic acid with octyl alcohols. Heading 2917 covers polycarboxylic acids, and the subheading 2917.32 is dedicated specifically to dioctyl orthophthalates. This chemical is one of the most widely used plasticizers globally, primarily utilized to impart flexibility to PVC resins. The classification is strictly determined by the chemical structure and the specific alcohol chain length (C8). Even if the product is intended for use in medical devices or flooring, as a pure chemical substance, it must be classified here according to the General Rules of Interpretation.

Common Misclassification

Dioctyl phthalate is most commonly misclassified under HS code 2917.33 (Dinonyl or didecyl orthophthalates) or 2917.34 (Other esters of orthophthalic acid). The confusion usually arises from the generic use of the term \"phthalate plasticizer.\" It is essential to distinguish the C8 (octyl) chain from C9 (nonyl) or C10 (decyl) chains to ensure the correct subheading is applied.
