Import Tips
• Ensure the blend is not a prepared additive or concrete mix, which would fall under heading 3824
• Provide the exact composition to demonstrate that the clinker content is below 50%, justifying classification as 'other hydraulic cement'
• Verify that the fly ash is not a separate product requiring its own classification
