Import Tips
• Include Prop 65 warning labels due to pulegone's reproductive toxicity classification in California
• Provide residual solvent analysis (<5000ppm) per USP <467> for pharmaceutical precursor imports
• Separate natural (≥97%) from synthetic pulegone; optical rotation differs and affects classification proofs
