Import Tips
• Include halogen content analysis (per chapter note 4) to confirm classification remains with pyrazole parent structure
• Customs may require proof of non-sulfonation to avoid organo-sulfur exclusion under heading 2930
• Avoid bulk packaging that suggests general chemical use; specify photographic-grade purity levels
