Import Tips
• Ensure USP certification and provide Certificate of Analysis (CoA) confirming purity >99% and absence of heavy metals to meet FDA import standards
• Declare as pharmaceutical precursor; obtain prior notice via FDA's PREDICT system to avoid detention at customs
• Verify batch-specific stability data as ferrous fumarate is sensitive to oxidation; improper packaging leads to common rejections
