Last updated: April 2026 dataSurface-treatment and conditioning preparations formulated with animal fats, vegetable oils, or synthetic esters — rather than petroleum-derived oils — are the defining feature of SITC 59773, separating them from their petroleum-containing counterparts. Castor oil–based textile lubricants, neatsfoot oil leather conditioners, and lanolin-based furskin treatments are representative products in this category. The non-petroleum origin of the oil or grease component is the classification pivot point, and importers of borderline formulations should obtain supplier certification of the oil source.
AI-written summary of the official U.S. Census Bureau trade figures on this page — verify before relying on it.
A supplier-issued certificate of composition or a full material safety data sheet (SDS) identifying the oil or grease component as animal- or vegetable-derived is the standard documentation. For complex blends, a laboratory analysis confirming the absence of petroleum or bituminous mineral oil fractions above a de minimis level provides the strongest classification support.
Classification depends on which oil type predominates and whether the petroleum fraction is sufficient to bring the product within the petroleum-containing heading (59771). If the petroleum content is negligible or incidental, classification under 59773 may still be appropriate, but this is a fact-specific determination. Consulting a licensed customs broker and obtaining a binding ruling is advisable for mixed-oil formulations.
