Import Tips & Compliance
• Provide Certificate of Analysis (CoA) confirming chemical identity and purity as per Chapter 29 notes for separate chemically defined compounds
• Ensure SDS includes GHS hazard classification for quinones (toxic, irritant) to meet EPA and OSHA import requirements
• Avoid misclassification as dyes (Chapter 32) by documenting non-coloring primary use
