Import Tips
• Obtain a commercial invoice specifying assay molybdenum content (Mo percentage) as per statistical notes for accurate duty assessment
• Ensure Certificate of Analysis (COA) from a certified lab verifies roasting process and metal purity to avoid reclassification
• Declare exact weight of molybdenum content without deductions; common pitfall is underreporting assay leading to penalties
