Product classification
HS code for Dinonyl phthalate: 2917.33
Acids, aromatic polycarboxylic acids, dinonyl or didecyl orthophthalates.
Classification of dinonyl phthalate under HS 2917.33
Dinonyl phthalate (DNP) is classified under HS code 2917.33. This classification is determined by its chemical structure as an ester of orthophthalic acid. Specifically, it falls within Chapter 29, which covers organic chemicals, and heading 2917, which encompasses polycarboxylic acids and their derivatives. Subheading 2917.33 is explicitly reserved for dinonyl or didecyl orthophthalates. These compounds are primarily used as plasticizers in the polymer industry, particularly for polyvinyl chloride (PVC), to enhance flexibility and durability. The classification is based on the length of the alkyl chain (nine carbons for dinonyl) and the aromatic nature of the parent acid. Under the General Rules of Interpretation (GRI), specifically GRI 1, the product is classified according to the terms of the headings and any relative section or chapter notes, which in this case provide a specific line item for this chemical.

Codes often confused with 2917.33
Common mistake. Dinonyl phthalate is frequently confused with HS code 2917.32, which is reserved for dioctyl orthophthalates (DOP/DEHP). While both are phthalate plasticizers, the distinction lies in the carbon chain length of the alcohol used in esterification. It may also be confused with 2917.34, which covers other esters of orthophthalic acid like dibutyl phthalate. Accurate classification requires verifying the specific alkyl group through a technical data sheet (TDS).
Top exporters and importers of HS 291733 (the code used for dinonyl phthalate), 2025
In 2025, the largest exporter of HS 291733 (the code used for dinonyl phthalate) in UN Comtrade data was the Netherlands, with 34% of world exports; the largest importer in UN Comtrade data was Italy, with 9.7% 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 that did not report are estimated from what other countries recorded trading with them. 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).
