U.S. imports of oleic acid (HS 382312) totaled $1.4M in April 2026, traded with 7 countries.
Importers of Oleic Acid paid $185K in duties in April 2026 — an effective duty rate of 15% on $1.2M in dutiable value, based on actual customs collections rather than the published tariff schedule. Oleic Acid imports of $1.4M in April 2026 ran 46% below the year-to-date monthly average of $2.6M.
Last updated: April 2026 dataA C18 monounsaturated fatty acid produced by hydrolysis and fractionation of vegetable or animal oils, industrial oleic acid is a key raw material for metalworking lubricants, surfactants, textile auxiliaries, and personal care formulations. Indonesia leads US import supply, driven by its large palm olein and oleochemical refining sector, with Canada and Malaysia also significant sources. Like stearic acid, commercial oleic acid is a mixture of fatty acids rather than a chemically pure compound, and the distinction from chapter 29 pure oleic acid turns on the C18:1 purity level documented in the certificate of analysis. Importers sourcing from Indonesia should be aware that Section 301 measures do not apply to this origin, but should verify current trade-remedy status given the dynamic tariff environment.

The Harmonized System and CBP practice treat fatty acids as 'industrial' when they are mixtures of fatty acid compositions typical of commercial processing — commercial oleic acid often contains linoleic, palmitoleic, and other fatty acids alongside the C18:1 fraction. A product marketed and certified as chemically pure oleic acid at very high purity would be classified in chapter 29. The supplier's certificate of analysis showing the full fatty acid profile is the primary classification evidence.
No — heading 3823 covers industrial monocarboxylic fatty acids regardless of whether they are derived from vegetable oils (such as palm) or animal fats (such as tallow). The classification is determined by the chemical composition and purity of the final product, not by the upstream feedstock. However, feedstock origin may be relevant for other regulatory purposes, such as USDA APHIS import requirements if animal-derived fats are involved in the production process.
