Import Tips
• Confirm the rottenstone is not calcined or mixed, as such processing would exclude it from Chapter 25
• Provide a description of the product's natural state and intended use as an abrasive
• Check if any anti-dusting agents are added, ensuring they do not alter the product's general use
