HS code for Dioctyl phthalate: 2917.32
Acids, aromatic polycarboxylic acids, dioctyl orthophthalates.
Classification of dioctyl phthalate under HS 2917.32
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.

Codes often confused with 2917.32
Common mistake. 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.
Top exporters and importers of HS 291732 (the code used for dioctyl phthalate), 2025

How these figures are built
109 countries reported 2025 trade to UN Comtrade in HS 2022, and their own totals are used. Countries marked * did not, so their figures add up what other countries recorded trading with them, and their exports are valued at buyers' CIF prices. Those estimates miss trade with other non-reporting countries, so they can be low, and a non-reporting country can rank higher than shown or be missing from the list. World totals add both and leave out trade between two non-reporting countries. Figures are in current US dollars; reported imports are mostly valued CIF and exports FOB, and exports include re-exports. The UN Comtrade links show the underlying records; they can also list a few reporters left out here (regional groups and older HS editions).
