A Drug Identification Number, or DIN, is an eight-digit number assigned by Health Canada to a drug product being marketed in Canada. It uniquely identifies the drug product as having been evaluated and authorized for sale in Canada, meaning it has undergone and passed a review of its formulation, labeling, and instructions for use. Once the DIN is assigned to the product, it can then be marketed in Canada. BMS complies with every request regarding the registration of STUD 100 including testing the product consistently for quality and covering yearly registration fees. DINs are required on all products defined as a drug under the Food and Drugs Act and any drug product sold without a DIN is not in compliance with Canadian Law.
