United Manganese of Kalahari (Pty) Ltd (UMK), a major manganese mining company, paid mineral royalties under the Mineral and Petroleum Resources Royalty Act 28 of 2008 for the 2010 and 2011 tax years. In calculating its royalties, UMK deducted expenditure it incurred on transport, insurance and handling (TIH) costs for manganese sold to foreign purchasers on FOB and CIF terms. SARS audited the returns and disputed the method used to determine UMK’s ‘gross sales’ under s 6 of the Royalty Act, contending that TIH costs could only be deducted where they were separately specified in the sales price. UMK sought declaratory relief in the High Court, which ruled in its favour. SARS appealed to the Supreme Court of Appeal.
