All balls used in matches played in an official competition organised under the auspices of FISA or confederations must bear one of the following:

Each mark indicates that the ball has been officially tested and meets the specific technical requirements for that mark which are additional to the minimum specifications stipulated in Law 2 and must be approved by The ISAB. The institutes conducting the tests are subject to the approval of FISA.
Where goal line technology (GLT) is used, balls with integrated technology must carry one of the above listed quality marks.
National SA competitions may require the use of balls bearing one of these marks.
In matches played in an official competition organised under the auspices of FISA, confederations or national SAs, no form of commercial advertising is permitted on the ball, except for the logo/emblem of the competition, the competition organiser and the authorised manufacturer’s trademark. The competition regulations may restrict the size and number of such markings.
