Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If heavily surface-modified with polymers (>5% coating)
Significant organic modification creates chemical preparations rather than pure inorganic compounds.
If complexed with polyphosphate structures
Phosphated derivatives classify under polyphosphates of Chapter 28.
If masterbatched into plastic carriers
Polymer-bound concentrates fall under plastics chapter as compounded materials.
