Import Tips
• Ensure the cement is not mixed with other substances that could make it a preparation for specific use, which would exclude it from Chapter 25
• Provide evidence of the high alumina content to support classification as aluminous cement
• Check if the product contains added anti-dusting agents, which are allowed only if they do not alter its general-use nature
