Alberto Ernesto Nharreluga, 47, and Alberto Erneto Nharreluga Junior, 27, were arrested in April 2019.
Police spokesperson Captain Dineo Sekgotodi said the rhino horns and shark fins were found by members of the Flying Squad on the N4 next to Belfast hidden inside the suspects' vehicle.
The two men were travelling from Mozambique to Gauteng when they were stopped by the police.
"During their arrest, the suspects tried to entice the police officials with a kickback but failed. The Serious Corruption Investigation members were alerted and they processed the crime scene and charged the suspects with possession of endangered species and an additional corruption charge.
"Last week, the Nharrelugas attempted to apply for bail but their effort was unsuccessful," she added.
