Durban harbour is key to South Africa’s grain trade. In the 2017/18 marketing year, South Africa exported 2.3 million tonnes of maize (white and yellow). About 74% of this went to markets through Durban harbour (nothing through other harbours), with the rest exported by road and rail to the continent.
The US soybean farmers, industry groups and government officials’ quest to look beyond China for exports markets might prove fruitless. There is just not enough demand outside China.
