Although issuing authorities claim that their CPP conform to WHO format (a statement to confirm whether or not the document is issued in the format recommended by WHO should be included in the certificate), their format and content may vary from an issuing country to another. Also, some authorities do not issue CPP if the respective drug is not licensed in the exporting country (e.g. Italy). In this last case, a Certificate of Exportation is issued instead, with a format and content similar to those of CPP.
