Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If support is calcium carbonate instead of barium sulfate
Different mineral supports may fall under general catalyst other.
If barium sulfate is primary imported material
Pure sulfates without catalyst function in Chapter 28.
If dedicated to specific antibiotic intermediate production
Specialized end-use in organics can override catalyst heading.
