Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If the cement is a hydraulic cement with additional properties not specific to aluminous cement
Other hydraulic cements not elsewhere specified are covered under 2523.90.00.
If the product is a prepared additive for cement, not a cement itself
Prepared additives for cements are classified under heading 38.24, not Chapter 25.

Import Tips & Compliance
• 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
