Import Tips
• Submit stability data confirming no prohibited stabilizers per Chapter 29 note (f) to maintain pure derivative status
• For USP-grade, include pharmacopeia certificates; common error is mislabeling as finished supplement
• Declare exact isomer form (ubidecarenone vs reduced ubiquinol) as mixtures of isomers follow note (b)
