Import Tips
• Provide assay certificates showing molybdenum content to distinguish from complex salts under 2842
• Declare as 'chemically defined' with exact CAS number (12054-85-2) to prevent reclassification as a preparation
• Comply with TSCA import requirements; notify EPA if annual volume exceeds 10,000 lbs
