HS code for DOP: 2917.32
Acids, aromatic polycarboxylic acids, dioctyl orthophthalates.
Classification of DOP under HS 2917.32
Dioctyl orthophthalates, commonly known as DOP or DEHP, are classified under HS code 291732. This classification is governed by the rules of Chapter 29, which covers organic chemicals. Specifically, heading 2917 is reserved for polycarboxylic acids, their anhydrides, halides, peroxides, and peroxyacids, as well as their halogenated, sulfonated, nitrated, or nitrosated derivatives. Within this heading, the aromatic polycarboxylic acids are further subdivided. DOP is an ester of phthalic acid, specifically the dioctyl ester of orthophthalic acid. Because it is a chemically defined organic compound and a specific ester of an aromatic polycarboxylic acid, it is assigned to the sub-heading 291732. The classification remains consistent regardless of whether the product is used as a plasticizer in PVC production or in other industrial applications, provided it remains a pure chemical substance not mixed with other plasticizers.

Codes often confused with 2917.32
Common mistake. DOP is frequently misclassified under HS code 291734, which is designated for dibutyl orthophthalates. While both are phthalate esters, the carbon chain length of the alcohol component distinguishes them. Another common error is classifying DOP under 291733, which covers dinonyl or didecyl orthophthalates. Furthermore, if DOP is imported as part of a prepared mixture of plasticizers for rubber or plastics, it should be classified under 381220 (compound plasticizers) rather than the pure chemical code of 291732. Importers must verify the chemical purity and the specific alcohol chain to ensure the correct sub-heading is applied.
Top exporters and importers of HS 291732 (the code used for DOP), 2025
In 2025, the largest exporter of HS 291732 (the code used for DOP) in UN Comtrade data was China, with 51% of world exports; the largest importer in UN Comtrade data was Vietnam, with about 7.8% of world imports. Countries that did not report 2025 data are estimated from partner records, which can understate them.

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).

Questions about DOP
What is the HS code for DOP?
The HS code for DOP is 291732 (Acids; aromatic polycarboxylic acids; dioctyl orthophthalates). The HS code for Dioctyl orthophthalates (DOP) is 291732.
How do I classify DOP for customs?
DOP is classified under HS code 291732 — Acids; aromatic polycarboxylic acids; dioctyl orthophthalates. This is a 6-digit subheading level code.
Is DOP classified differently if used for medical devices?
No, the HS code 291732 is based on the chemical identity of the substance. Even if the DOP is intended for medical-grade PVC, it remains under this code as long as it is the unmixed chemical compound.
Which countries are the top exporters of DOP (HS 291732)?
In 2025, the top exporters of HS 291732 (the code used for DOP) in UN Comtrade data were China ($170M, 51% of world exports), Malaysia ($54M) and South Korea ($31M). World exports came to about $332M, adding countries' reported figures and partner-based estimates for those that did not report (UN Comtrade data). Countries that did not report 2025 data are estimated from partner records, which can understate them.
Which countries are the top importers of DOP (HS 291732)?
In 2025, the top importers of HS 291732 (the code used for DOP) in UN Comtrade data were Vietnam (about $25M, 7.8% of world imports), Nigeria ($22M) and India ($19M). World imports came to about $314M, adding countries' reported figures and partner-based estimates for those that did not report (UN Comtrade data). Countries that did not report 2025 data are estimated from partner records, which can understate them.
