• Provide laser diffraction particle size analysis to confirm micronization doesn't constitute 'mixture' status
• Label as 'nicotinic acid' per INN; avoid 'vitamin' terminology that might trigger FDA supplement scrutiny
• Verify GMP manufacturing to qualify for reduced duties under pharmaceutical tariff preferences
