Branched Alkylbenzene Lubricant Additive from China
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.

Import Tips
• Provide flash point and viscosity specs to demonstrate lubricant additive function, preventing misclassification
• Include alkylation process documentation to prove synthetic origin versus petroleum fractions
• Watch for contamination thresholds that could shift classification to waste mixtures under 3825
