The Proteas were found by match referee Andy Pycroft to have been three overs short of their target, with allowances taken into consideration
South Africa's players have all been fined and the team penalised six World Test Championship points for a slow over rate during the fourth Test against England in Johannesburg.
The Proteas were found to have been three overs short of their target, with allowances taken into consideration.
Each of the 11 members of the side have subsequently been docked 60 per cent of their match fees in addition to the points penalty.
Captain Faf du Plessis pleaded guilty to the offence and accepted the proposed sanction, avoiding the need for a formal hearing.
It is the first time that a team has received a points penalty in the World Test Championship, which is in its inaugural season.
South Africa were beaten by 191 runs at the Wanderers on Monday to slip to a 3-1 series defeat.
