Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If synthetically produced or chemically purified
Synthetic sodium hexafluoroaluminate is classified as a fluoride compound in Chapter 28, not natural minerals.
If containing significant aluminum ore impurities
High aluminum content may classify it under aluminum ores rather than nes minerals in Chapter 25.
If sold as prepared chemical for industrial processing
Processed or prepared forms for specific uses fall under Chapter 38 chemical preparations.
