Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If tableted or capsulated for retail sale
Finished dosage forms containing aspirin salts classify in Chapter 30 as medicaments, not bulk chemicals.
If primarily calcium carbonate impurity dominates
High inorganic content might shift to Chapter 28 metal carbonates if organic acid function is secondary.
