1.      Plastic balls will be used at ITTF Sanctioned events from 1st July 2014 (reference: ITTF BoD decision 2012)

2.      As an exception celluloid balls will be used at the 2014 Youth Olympic Games (reference: ITTF OPC decision 2014) and at four (4) ITTF Junior Circuit events taking place after 1st July 2014 but before the 2014 YOG (reference: ITTF EC decision 2014)
