SITCSection 4
U.S. imports of hydrogenated & interesterified vegetable fats and oils (SITC 43122) totaled $17.4M in April 2026, traded with 36 countries.
Importers of Hydrogenated & Interesterified Vegetable Fats and Oils paid $1.5M in duties in April 2026 — an effective duty rate of 12% on $12.2M in dutiable value, based on actual customs collections rather than the published tariff schedule. Hydrogenated & Interesterified Vegetable Fats and Oils imports of $17.4M in April 2026 ran 33% above the year-to-date monthly average of $13.1M.
Last updated: April 2026 dataChemically modified vegetable oils — including hydrogenated palm, soybean, and rapeseed (canola) oil fractions — are widely traded inputs for the food processing, confectionery, and personal care industries, where controlled melting behavior and extended shelf life are essential. The interesterification or hydrogenation step distinguishes these products from commodity vegetable oils and places them in a separate trade classification. Palm-derived fractions dominate global supply of this category, making origin documentation and sustainability certifications (such as RSPO) increasingly relevant for US buyers sourcing from Southeast Asian producers.

The key distinction is the chemical modification process: hydrogenation, interesterification, esterification, or re-esterification must have occurred. Refined but unmodified vegetable oils are classified under different SITC headings. Importers should obtain a processing certificate or technical data sheet from the supplier confirming the modification method to support correct classification.
While US Customs does not currently mandate sustainability certification for palm-derived fats, buyers should be aware that Withhold Release Orders (WROs) under the Tariff Act can block goods linked to forced labor in specific supply chains. Maintaining traceability documentation back to the mill or plantation level is increasingly standard practice for risk management.
