Import Tips
• Include scanning electron microscopy (SEM) reports confirming micron particle size for primary form verification
• Label as 'not for medical use' if applicable to avoid stricter FDA import scrutiny
• Avoid declaring end-use (e.g
• 'for ink') as it risks reclassification to finished preparations
