Mixed Alkylnaphthalene Synthetic Base Oil

Mixed alkylnaphthalenes are alkylated naphthalene derivatives used as high-temperature synthetic lubricants in compressors and turbines. HTS 3817.00.1500 covers these as other mixed alkylbenzenes/naphthalenes, excluding purer forms in 2902. Their multi-alkyl chain composition provides superior oxidation resistance.

Import Tips & Compliance

Submit GC-MS analysis showing naphthalene core with mixed alkyl substituents for proper 3817 classification

Declare exact carbon chain lengths (C10-C14 typical) to avoid 2902 pure hydrocarbon confusion

Ensure packaging labels 'synthetic lubricant component' not 'solvent' to prevent 3825 waste classification

Linear Alkylbenzene (LAB) for Detergent Production

Linear alkylbenzene is a mixture of alkylbenzenes used primarily as a precursor in manufacturing linear alkylbenzene sulfonate (LAS) detergents. It falls under HTS 3817.00.1500 as 'other' mixed alkylbenzenes, distinct from those in headings 2707 or 2902 due to its synthetic branched and linear chain composition. This classification applies to industrial-grade mixtures not purely petroleum-derived.

Branched Alkylbenzene Lubricant Additive

Branched alkylbenzene mixtures serve as synthetic base stocks in high-performance lubricants and hydraulic fluids. Classified under HTS 3817.00.1500 as other mixed alkylbenzenes, these differ from pure isomers by their complex alkyl chain distribution from alkylation processes. Used in automotive and industrial applications requiring thermal stability.
