On 18 December 2015, South African Revenue Service (SARS) reduced the import tariff on beet and cane sugar (HS 1701.12, 1701.13, 1701.14, 1701.91, 1701.99) from 304c/kg (approx. USD 0.22kg) to 245.4/kg (approx. USD 0.16 per kg)

The SARS uses a variable tariff formula in order to adjust the import duty to a dollar-based reference price (DBRP). The DBRP represents the lowest duty-free price an importer pays in order to import goods the Southern African Customs Union (SACU). In case the price dips below the DBRP, a duty is levied.
On 11 April 2016, the import tariff was further reduced to Rand 239.5/kg (approx. USD 0.16 per kg), see related measure.
