U.S. imports of saturated acyclic monocarboxylic acids and derivatives, nesoi (HS 291590) totaled $28.3M in April 2026, traded with 31 countries.
Importers of Saturated Acyclic Monocarboxylic Acids and Derivatives, NESOI paid $1.2M in duties in April 2026 — an effective duty rate of 5.0% on $24.7M in dutiable value, based on actual customs collections rather than the published tariff schedule.
Last updated: April 2026 dataA residual catch-all for saturated acyclic monocarboxylic acids and their halides, anhydrides, peroxides, and peroxyacids not enumerated elsewhere in heading 2915, this group spans commercially significant compounds including lauric acid (2915901010), valproic acid (2915901400), and perfluorooctanoic acid (PFOA) and its salts (2915901810) — the last of which is subject to EPA regulatory scrutiny as a persistent organic pollutant. Malaysia and Indonesia lead US import supply, driven by lauric acid and other coconut- and palm-kernel-derived fatty acids. Importers of PFOA and related per- and polyfluoroalkyl substances (PFAS) should monitor evolving EPA reporting and import restrictions.
AI-written summary of the official U.S. Census Bureau trade figures on this page — verify before relying on it.
PFOA and its salts, classified at 2915901810, are subject to EPA restrictions under the Toxic Substances Control Act (TSCA) and are listed as significant new use chemicals. Importers must comply with TSCA Section 5 significant new use rules (SNURs) and may be required to submit notifications to EPA before importing. Given ongoing regulatory developments around PFAS compounds, importers should consult with environmental counsel before entry.
Lauric acid (C12 saturated fatty acid) is specifically enumerated at 2915901010, separating it from other fatty acids of animal or vegetable origin (2915901050) and from non-fatty-acid saturated monocarboxylic derivatives (2915901890). A certificate of analysis confirming the carbon chain length and purity is the standard supporting document for claiming the lauric acid-specific line.
