HS Code 3817 — Mixed Alkylbenzenes and Naphthalenes

This heading covers mixtures of hydrocarbons used primarily as precursors in the production of detergents and lubricants. These are synthetic mixtures rather than pure chemical isolates or direct petroleum distillates.

What's included

Linear alkylbenzene (LAB)
Branched alkylbenzene (BAB)
Mixed alkylnaphthalenes
Dodecylbenzene mixtures

What's excluded

Pure benzene → use 2902 (Chemically pure monomers or isomers belong in Chapter 29.)
Mixed oils from coal tar → use 2707 (Oils where aromatic constituents exceed non-aromatic by weight are in Chapter 27.)

Common examples

Mixed alkylbenzenes for detergent manufacturing
Alkylnaphthalene thermal fluids
LAB for sulphonation
Heavy alkylates

Frequently asked questions

What is the difference between 2707 and 3817?

2707 covers oils obtained from coal tar distillation, whereas 3817 covers synthetic mixtures obtained by the alkylation of benzene or naphthalene.
