A TUE request to your National Anti-Doping Organisation must be submitted by those athletes who question the prohibited substance or prohibited method due to medical conditions and who are national-level athletes according to antidoping rules of your country (athletes who compete at national level championships and any other national sport competitions organised by the sport federation of your country unless mentioned athletes belong to international-level athletes according to criteria set by his or her international sport federation).
International-level athletes as they are defined by each international sport federation must submit a TUE application to his or her international federation.
Those athletes who are not an international-level or national-level athletes are not obliged to submit a TUE application form prior to competition and may apply for a retroactive TUE in 5 working days after notification of an adverse analytical finding.
