Import Tips
• Include manufacturer specs detailing clay expansion temperature (typically 1100-1200°C) to prove classification
• Label packages clearly as 'expanded mineral material' to prevent confusion with raw clay imports
• Check for intermixture declarations if blended with other expanded minerals
