Import Tips
• Include alumina and silica content analysis to confirm refractory clay status under other clays
• Document as 'not calcined' to avoid 2508.50-2508.70 subheadings for andalusite, kyanite, or chamotte
• Avoid pitfall of importing pre-mixed with binders, which may classify as mixtures under 3816
