Last updated: August 2026 dataOrthophthalic acid esters not elsewhere specified — including dibutyl phthalate (DBP) and a range of specialty phthalate esters — serve as plasticizers, solvents, and chemical intermediates across adhesives, coatings, and pharmaceutical excipient applications. Canada is the leading US supplier under this heading, with India and Sweden also significant sources. The US schedule distinguishes dibutyl orthophthalates (2917340110) from all other orthophthalic acid esters (2917340150), and DBP specifically is subject to regulatory restrictions in consumer products under CPSIA. Importers should verify end-use compliance requirements, as phthalate ester regulations vary significantly by application and jurisdiction.

DBP (2917340110) is separately enumerated because of its distinct commercial significance and regulatory profile — it is permanently banned above 0.1% in children's toys and child care articles under CPSIA, and its specific identification in the tariff schedule facilitates targeted enforcement and trade data collection. All other orthophthalic acid esters not specifically named elsewhere are captured under 2917340150.
Importers should obtain a supplier certificate of analysis confirming the chemical identity (CAS number, IUPAC name, and molecular structure), as well as a manufacturer's declaration of the production process. If the product could plausibly be classified as a dioctyl, dinonyl, or didecyl phthalate under headings 291732 or 291733, a binding ruling request to CBP is advisable to avoid misclassification risk.
