Further to being subject to doping control on 21 May 2025, Mr. Kim, an international level athlete, was found to have the Specified Substance Tramadol, a narcotic, in his system.

The athlete’s period of ineligibility will conclude on 15 July 2026. Until that time, the athlete is subject to a prohibition against participation pursuant to Article 10.4.1 of the IGF Anti-Doping Rules.
