Import Tips & Compliance
• Include flash point and viscosity specs in documentation; VOC content may trigger air quality regs
• Separate from naphthenate driers to avoid 3824.99.7590
• Register with TSCA if first import

Industrial Grade Naphthenic Acid 75%
High-purity naphthenic acid derived from petroleum distillates, primarily used as a corrosion inhibitor and paint drier in industrial formulations. Classified under HTS 3824.99.7510 as pure naphthenic acids, distinct from their salts or esters. Their carboxylic acid structure enables metal complexing for anti-corrosion applications.
Refined High Acid Number Naphthenic Acid
Distilled naphthenic acid with acid number 200-250 mg KOH/g, used in metalworking fluids and rubber additives. Falls under HTS 3824.99.7510 as their water-insoluble salts are separately classified. Key for emulsifiers in oil-based formulations.
Technical Grade Naphthenic Acid (60% Assay)
Standard technical naphthenic acid at 60% minimum assay from heavy petroleum distillates, for wood preservatives and fuel additives. Pure acid classification under 3824.99.7510 excludes formulated products. Versatile for salt formation and emulsification.
Distilled Naphthenic Acid for Rubber Accelerator
Fractionally distilled naphthenic acid for rubber vulcanization accelerators and plasticizers. HTS 3824.99.7510 specifically identifies the acid before reaction with amines or metals. Narrow boiling range ensures processing consistency.
