Intanon failed an out-of-competition drug test in April but was not banned by the BWF. The BWF statement reads: "The ethics hearing panel determined Ms. Ratchanok Intanon committed an anti-doping rule violation, but as the athlete was able to demonstrate that her adverse analytical finding was related to the ingestion of meat contaminated with clenbuterol, she was found to bear no fault or negligence for the violation, and thus no period of ineligibility has been imposed on her." She lost again to Chen Yufei in the final of the Hong Kong Open. She participated in the World Tour Finals, where she beat Busanan Ongbamrungphan, lost to Tai Tzu-ying, and lost to Nozomi Okuhara in the last group match. Intanon's first title of 2020 came when she won the Indonesia Masters title by beating Carolina Marín in three game.
