Import Tips
• Include spectral analysis (NMR, IR) confirming pyrazole ring structure and substitution pattern
• Document supply chain to major film manufacturers to support photographic chemical designation
• Avoid bulk packaging over 25kg; smaller units reinforce specialty chemical status vs commodity organic
