The Ugandan government has imposed a $200 levy per kilogram on refined gold exports and banned the export of unrefined gold. This move is part of the government's efforts to maximize the economic benefits from the country's gold exports. 
The new regulations also include a 5% tax on the value of each kilogram of unprocessed gold exports.[1][2][5] The government's aggressive pursuit of revenue from the lucrative gold export industry has led to protracted negotiations with gold exporters, which at one point resulted in a complete halt of gold exports from Uganda.[4][5]
