Import Tips
• Include mineral composition analysis (Na2O, Al2O3 content) in import docs to substantiate feldspar classification
• Declare exact particle size distribution to distinguish from powders that might edge into other categories
• Check for radioactive impurities common in feldspar deposits, as high levels trigger additional NRC regulations
