Import Tips & Compliance
• Distinguish between natural fluorspar (calcium fluoride of mineral origin) and synthetic calcium fluoride, as natural fluorspar may be classified under heading 2529
• Provide a certificate of analysis to confirm the product is chemically defined and meets the criteria for Chapter 28
• If the calcium fluoride is used in metallurgy, declare the end use to support classification
