U.S. exports of Lubricating Oil Additives Containing Petroleum or Bituminous Mineral Oils (HS 381121) totaled $183.2M in August 2026.
Importers of Lubricating Oil Additives Containing Petroleum or Bituminous Mineral Oils paid $6.0M in duties in August 2026, an average duty rate of 11.17% — duty actually collected as a share of the imports that cleared customs, not the published tariff schedule.
Last updated: August 2026 dataPetroleum-oil-containing lubricant additives — detergents, dispersants, viscosity-index improvers, and anti-wear packages blended into a mineral oil carrier — are classified under a single 10-digit line (3811210000) and are a critical input for finished engine oil and industrial lubricant formulations. France leads US import supply, followed by Mexico and Italy, reflecting the global footprint of major additive technology companies headquartered in Europe and their North American blending operations. Because these preparations contain petroleum-derived carrier oils, importers must confirm whether the petroleum content triggers any additional customs valuation or chemical reporting obligations.

The dividing line is whether the preparation contains petroleum oils or oils obtained from bituminous minerals as a component. If it does, classification falls under 381121; if the carrier or base is non-petroleum (e.g., synthetic ester or polyalkylene glycol), the preparation falls under 381129. This distinction is important because the two headings carry different tariff treatment, and misclassification is a common audit finding for lubricant additive importers.
While China does not appear among the top suppliers for this specific heading, any petroleum-oil-containing lubricant additive originating from China would need to be evaluated for Section 301 exposure. Importers sourcing from multiple origins should verify the country of origin of the additive concentrate itself, not just the blending location, as processing in a third country does not automatically confer a new origin.
