Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If for aviation gasoline blending
Aviation gasoline mixtures are classified under petroleum spirits in Chapter 27.
If contains performance additives beyond stabilizers
Chemical preparations with specific additives exceed Chapter 29's chemically defined scope.
If for lower C4 hydrocarbons misdeclared
Butane-specific subheading has lower numerical order precedence if applicable.

Import Tips & Compliance
• Include octane number certification; critical for fuel additive verification during customs exam
• Classify as UN1262, PG II; ensure stainless steel or approved plastic containers for compatibility
• Document as chemically defined compound, not mixture, to prevent reclassification to Chapter 27 or 38
