U.S. imports of castor oil & fractions (whether or not refined, not chemically modified) (HS 151530) totaled $2.8M in April 2026, traded with 12 countries.
Importers of Castor Oil & Fractions (Whether or Not Refined, Not Chemically Modified) paid $433K in duties in April 2026 — an effective duty rate of 10% on $4.3M in dutiable value, based on actual customs collections rather than the published tariff schedule. Castor Oil & Fractions (Whether or Not Refined, Not Chemically Modified) imports of $2.8M in April 2026 ran 60% below the year-to-date monthly average of $7.0M.
Last updated: April 2026 dataCastor oil's uniquely high ricinoleic acid content makes it irreplaceable in specialty lubricants, hydraulic fluids, nylon-11 polymer production, and cosmetic formulations — applications that drive consistent industrial demand regardless of food-oil price cycles. India overwhelmingly dominates global castor oil production and is the primary US supplier, with China a secondary source; this concentration creates meaningful supply-chain risk for manufacturers dependent on uninterrupted flow. A single tariff line (1515300000) covers crude, refined, and fractionated castor oil, so the processing state does not affect classification at the 10-digit level.
AI-written summary of the official U.S. Census Bureau trade figures on this page — verify before relying on it.
Unlike most vegetable oils, which have separate headings for crude and refined grades, castor oil and its fractions — whether crude, refined, or fractionated — all fall under 1515300000. This is because the HS nomenclature treats castor oil as a distinct commodity defined by its botanical origin and fatty acid profile rather than its processing state. Importers should still document the refining level for FDA food-use compliance if applicable.
India accounts for the vast majority of global castor bean cultivation and crushing, making it the near-exclusive origin for US castor oil imports. This concentration means that monsoon variability, Indian export policy changes, or logistics disruptions can cause significant price and availability swings. Buyers reliant on castor oil for polymer or lubricant production often maintain strategic inventory buffers or dual-source from secondary suppliers such as China to manage this risk.
