U.S. imports of palmitic acid, stearic acid, their salts and esters (HS 291570) totaled $8.8M in April 2026, traded with 25 countries.
Importers of Palmitic Acid, Stearic Acid, Their Salts and Esters paid $1.2M in duties in April 2026 — an effective duty rate of 15% on $7.8M in dutiable value, based on actual customs collections rather than the published tariff schedule. Palmitic Acid, Stearic Acid, Their Salts and Esters imports of $8.8M in April 2026 ran 19% above the year-to-date monthly average of $7.3M.
Last updated: April 2026 dataDerived predominantly from palm and animal fats, palmitic and stearic acids are saturated C16 and C18 fatty acids widely used as emulsifiers, lubricants, and surfactant intermediates in personal care, food processing, and plastics manufacturing. Indonesia and Malaysia dominate US import supply under this heading, reflecting their position as the world's largest palm oil producers and the downstream fatty acid refining capacity concentrated in Southeast Asia. The US schedule enumerates palmitic acid (2915700110), stearic acid (2915700120), and their salts and esters (2915700150) as distinct 10-digit lines.
AI-written summary of the official U.S. Census Bureau trade figures on this page — verify before relying on it.
Mixed fatty acid fractions are classified based on their predominant component or, if not clearly predominant, under the residual or most specific applicable line. CBP may require a certificate of analysis showing the fatty acid composition profile to determine the correct 10-digit line. If the mixture does not meet the specification for either pure acid, it may fall under a broader fatty acid heading elsewhere in Chapter 29 or Chapter 38.
While US customs law does not currently mandate sustainability certification for palm-derived fatty acids, importers should be aware that goods produced with forced labor are subject to exclusion under the Uyghur Forced Labor Prevention Act and related CBP enforcement actions. Additionally, some downstream customers and retailers require RSPO (Roundtable on Sustainable Palm Oil) certification, which is a commercial rather than regulatory requirement but increasingly affects supply-chain documentation practices.
