Import Duty Rates by Country of Origin
Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If imported as 90%+ active anionic surfactant preparation
Commercial detergent formulations classify in Chapter 34 rather than pure chemicals.
If classified as styrene/stilbene derivatives
Certain alkyl aromatics without sulfonation fall under cyclic hydrocarbons.
If blended with hydrotropes or builders
Surfactant mixtures for specific applications move to chemical preparations.

Import Tips & Compliance
• Document alkyl chain length distribution (C10-C14 typical) to confirm linear alkylbenzene sulfonate identity
• Biodegradability testing may be required under EPA Clean Water Act for wastewater discharge
• Neutralize to sodium salt form post-import if selling as LAS detergent active
