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
