Import Tips
• Import with full synthetic pathway documentation proving structure matches tariff nomenclature exactly
• Hazardous material shipping requirements apply (ORM-D or proper UN number); verify DG compliance
• Avoid classification error as general organo-sulfur under 2930—diazo function takes precedence per Chapter 29 notes
