Our grades

Crystal grades

  • Nine grades of ASA crystal are manufactured within CHC production sites from coarse to fine particles.
  • These crystal grades can be blended with others ingredients, excipients and are suitable for various finished dosage forms such as sachets, tablets, capsules, chewable tablets…


  • 2 grades of ASA powder are available from our sites.
  • Their excellent dissolution properties make them particularly suitable for effervescent tablets and suppositories applications.


  • Only dry granulation is suitable for aspirin as it is sensitive to humidity. 2 types of granular grades are manufactured within CHC : 100% ASA and 90% ASA granulates.
  • Both granulates type of products are compliant with US and EU pharmacopeias and exhibit excellent flow properties.
  • 100% ASA granulates are particularly recommended for formulated tablets, high speed tableting machines and exhibit excellent dissolution.
  • The four grades containing 90% aspirin are directly compressible as is. They are suitable for slow or fast release and can be compressed with excipients and APIs.
