Import Tips
• Obtain material safety data sheets (MSDS) and purity certificates to verify it meets 'chemically defined' criteria under subheading note
• Ensure DOT-compliant cylinders with proper pressure ratings; common pitfall is inadequate hazardous material declarations
• Declare exact purity levels to prevent reclassification as gas mixtures under heading 3824
