Last updated: August 2026 dataMineral-oil-based lubricants and greases — ranging from automotive engine oils and gear oils to industrial greases and metalworking fluids — are classified under NAICS 324191 and represent a technically differentiated segment of petroleum product trade. Viscosity grade (ISO VG, SAE), additive package, and base-oil quality tier (Group I through Group III+) are the primary specification axes that determine both pricing and end-use suitability. Imports of finished lubricants may be subject to Section 301 tariff exposure depending on country of origin and product formulation.

The American Petroleum Institute's base-oil group system (Groups I–V) defines refining quality and performance characteristics, but HTS classification of finished lubricants depends on the product's form, viscosity, and whether it is put up for retail sale or in bulk. A lubricant blended from Group III base oil is not automatically classified differently from a Group I blend — the HTS description governs, not the API group designation.
Finished lubricating oils and greases sourced from certain countries may be subject to Section 301 tariffs depending on origin and HTS classification. Importers should verify current Section 301 applicability for their specific product and country of origin with a licensed customs broker, as coverage and rates have evolved through successive USTR actions.
