Acting commissioner Thezi Mabuza said investigators were empowered by the act to investigate imported consignments and those detained by custom officials to verify if they met the requirements.
"While government encourages people to start their own businesses, the NCC will never tolerate acts of bribery by unscrupulous suppliers," said Mabuza.
"Our investigators will continue to conduct these inspections in ensuring that suppliers do comply with the CPA. Where we find reasonable suspicion of suppliers flouting the CPA, we will decisively take appropriate actions against those suppliers.
"The NCC wants to reiterate its commitment to implementing the CPA with the purpose of promoting and advancing the social and economic welfare of consumer in the country."
