According to the Section 35 (1) of the Electronic Communications Act - use of any type of electronic communications equipment or electronic communications facility, including radio apparatus is exempted from being supplied, sold, or distributed in South Africa. 

Additionally, ICASA type approval ensures that all the electronic communications equipment or electronic communications facility, including radio apparatus have been authorized to use or import in South Africa. Though the authorization will only be given if a product has met the technical standards.

These technical standards or specifications are established or determined by the authority based on the standards established by recognized international, regional and national standards-making bodies.

Though, excluding the products which fall under the purview of Type approval, products (non-type approval products) do not fall under the same, can not be sold or distributed in South Africa.
