Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If primarily aluminum-bearing with >2% Al content
Aluminum ores take precedence over nes minerals classification.
If for lower-grade flux materials
Other clays and similar fluxing materials classified in heading 2508.
If containing hypophosphites or phosphides
Specific chemical compounds excluded from Chapter 25 per legal notes.
