This article on News24 is about an order to the internal purchase division of the Tshwane metro council (a major municipality) stating that:

“No white businesses may in future be considered when the council purchased goods for less than R30 000. The same applies to tenders.”

From the article:

A council official who wanted to remain anonymous for fear of losing his job, said white businesses were approved in the past if their quotations were cheaper.

“We were told last week to buy only from black businesses. I paid between R6 000 and R7 000 more for goods to comply with the new requirements.

“This is going to become an expensive order,” he predicted.
