Import Tips
• Obtain mill test certificates verifying tin content exceeds other elements and meets subheading note (b) criteria to avoid reclassification
• Declare exact chemical composition on entry documents; discrepancies can trigger audits by CBP
• Ensure product is truly unwrought (not worked beyond simple casting) to prevent misclassification under Chapter 74 headings for semifinished goods
