Import Tips
• Verify purity and chemical composition via lab analysis to confirm classification as chemically defined calcium carbonate under Chapter 28
• Provide Certificates of Analysis (COA) showing >95% CaCO3 content to avoid misclassification as mineral products
• Ensure proper labeling as 'precipitated' or 'synthetic' to distinguish from ground limestone
