Mixed Alkylnaphthalene Synthetic Base Oil from Japan
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
• 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
