Import Tips
• USP certificate mandatory; include HPLC chromatogram showing single peak at 99%+ area for CBP verification
• Type II DMF filing required before first import; avoid 'research use only' labeling which triggers different regulatory path
• Particle size distribution data prevents reclassification as micronized finished intermediate under Chapter 30
