Import Tips
• Include persistence duration test results (e.g
• glow time >10 hours) to substantiate luminophore classification per chapter notes
• Ensure packaging labels specify 'luminophore for phosphorescent use' to prevent confusion with general aluminate compounds
• Watch for REACH compliance if importing to EU markets, as rare earth dopants require registration
