Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If vanadates or other excluded carbonate forms
Chapter exclusions redirect certain phosphatic/vanadic compounds away from carbonate headings.
If already incorporated into finished refractory ceramic goods
Once processed into ceramic articles, classification moves from chemicals to finished refractories.
If used as catalyst support in reaction mixtures
Catalyst preparations containing the compound shift to Chapter 38 spent catalysts or supports.
