Import Tips
• Verify chemical purity and provide Certificate of Analysis (CoA) to confirm classification as a fast color base under Chapter 29 note (a)
• Ensure SDS includes CAS number and structure to avoid reclassification as coloring matter under Chapter 32
• Declare exact isomer content; mixtures may shift to different subheadings if not chemically defined
