Import Tips
• Verify purity and provide chemical analysis certificates to confirm it meets 'chemically defined' criteria under Chapter 29 note (a)
• Include safety data sheets (SDS) as stabilizers or anti-dusting agents are allowed per note (f) and (g) without reclassification
• Avoid retail packaging over standard transport sizes to prevent exclusion under chapter exclusions for consumer forms
