Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If stearic acid grade > stearic but < oleic content
Industrial fatty acid mixtures classified by fatty acid profile rather than individual pure compounds.
If cyclohexane ring present making it cycloaliphatic
Cycloaliphatic acids classified in 2916 separate from acyclic saturated acids.
If aqueous solution concentration standardized
Chapter 29 note 2(d) permits water-dissolved organic acids to retain parent classification.

Import Tips & Compliance
• Submit REACH/TSCA registration numbers for industrial chemical import clearance
• Use stainless steel containers to prevent reaction with packaging materials
• Confirm aliphatic C8 structure to distinguish from aromatic octanoic acid derivatives (2916)
