U.S. imports of prepared additives for mineral oils and similar liquids (nesoi) (HS 381190) totaled $9.1M in April 2026, traded with 23 countries.
Importers of Prepared Additives for Mineral Oils and Similar Liquids (NESOI) paid $1.2M in duties in April 2026 — an effective duty rate of 16% on $7.6M in dutiable value, based on actual customs collections rather than the published tariff schedule.
Last updated: April 2026 dataPrepared additives for gasoline, diesel, and other mineral-oil-based liquids not covered by the lubricating oil additive headings are classified under 3811900000, capturing a broad range of fuel performance chemicals including cetane improvers, corrosion inhibitors, and deposit-control additives. Germany and India are the leading US import sources, with the United Kingdom, Canada, and Mexico also supplying significant volumes — a supplier mix that reflects both European specialty chemical leadership and North American blending proximity. Importers should verify that fuel additive formulations destined for US motor fuel blending carry valid EPA fuel additive registrations, as the registration requirement applies regardless of the additive's country of origin.

This line captures additives formulated for gasoline, diesel, aviation fuel, or other mineral-oil-based liquids used for the same purpose — such as cetane improvers, fuel system deposit-control additives, corrosion inhibitors for fuel tanks, and demulsifiers. Products specifically designed to improve the performance of lubricating oils fall under 381121 or 381129 depending on their carrier oil composition.
Yes. Multi-function additive packages that combine, for example, an antioxidant with a corrosion inhibitor and a detergent can be difficult to classify if the primary function is not clearly documented. CBP generally classifies such mixtures by the component that imparts the essential character, but when functions are co-equal, the heading that appears last in the tariff schedule may govern. A binding ruling from CBP is advisable for complex formulations.
