Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If primarily Portland cement clinker with minor alumina
Clinkers dominated by Portland composition fall under 2523.10 regardless of additives.
If imported as aluminum ore precursor rather than processed clinker
Raw aluminum-bearing minerals are in Chapter 26, not processed cements.

Import Tips & Compliance
• Declare clinker status explicitly; grinding doesn't change heading but affects value
• Monitor silica content as high levels may trigger alternative classification reviews
