Dead-Burn Refractory Magnesite from United States
Dead-burn refractory magnesite in large particles (2-6mm) is a natural magnesium carbonate mineral used as a soil amendment to supply magnesium and neutralize acidity. It falls under tariff item 2519.10.00 because it is in its crude state, having only been crushed and screened without any further processing such as calcination or sintering.

Import Tips
• Ensure the magnesite is unprocessed beyond crushing and screening; any calcination or sintering would shift classification to other items
• Declare the product as natural magnesium carbonate for agricultural use, and be prepared to provide a certificate of analysis to confirm composition
• Check with the Canadian Food Inspection Agency if the soil amendment claims specific agricultural benefits
