Last updated: July 2026 dataButyric and valeric acids and their derivatives serve dual roles as flavor and fragrance ingredients — where esters such as butyl butyrate and amyl valerate are valued for fruity aroma profiles — and as specialty chemical intermediates in pharmaceutical and polymer applications. Germany is the leading US import source, followed by India and China. The heading's three 10-digit lines separate aromatic salts and esters (2915601000) from the free acids and non-aromatic derivatives (2915605000), with an older consolidated line (2915600000) also present in the schedule.

Normal butyric acid (n-butyric acid) and isobutyric acid are structural isomers with different CAS numbers. Normal butyric acid and its derivatives fall under heading 2915.60, while isobutyric acid and its derivatives are classified elsewhere in Chapter 29. The commercial invoice should specify the isomeric form and CAS number to support the correct classification.
Butyric acid esters intended for use as food flavorings are subject to FDA oversight under food additive and GRAS regulations. Importers should confirm that the specific ester is listed or affirmed as GRAS for its intended application, and entry documentation should clearly identify the compound and its intended end use to facilitate FDA review.
