Import Tips
• Provide certificates of analysis confirming diazo purity and photographic-grade specifications to avoid reclassification
• Declare exact chemical composition and CAS number on commercial invoice to comply with TSCA import requirements
• Avoid bulk packaging that suggests industrial non-photographic use, which could trigger Chapter 28 scrutiny
