Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If tableted, coated, or packaged for retail sale as medicaments
Finished aspirin tablets shift to Chapter 30 for medicaments, excluding pure chemical compounds
If in salt form like calcium or magnesium acetylsalicylate
Salts of o-acetylsalicylic acid classify separately under the same heading but different subheading
If mixed with excipients as bulk intermediate for pharma production
Mixtures beyond Chapter 29 scope may fall under chemical preparations if not chemically defined
