Import Tips
• Include third-party lab certificates confirming purity levels to avoid disputes over 'chemically defined' status
• Declare as UN1049 compressed gas with proper placarding for hazmat shipping requirements
• Check end-use declarations; lab vs industrial use doesn't change classification but affects documentation
