The Commissioner for the South African Revenue Services v Foskor (Pty) Ltd

Foskor (Pty) Ltd is a mining company that acquired phosphate-bearing ore (foskorite) from Phalaborwa Mining Company Limited (PMC) pursuant to agreements entered into in 1979. PMC mined the ore and delivered it to Foskor, who paid mining and transport costs and became owner upon delivery. Between 1979 and 1998, approximately 183 million metric tons of foskorite were dumped by PMC for processing by Foskor. Foskor subjected the ore to complex processes including crushing, milling, flotation, magnetic concentration and gravity separation to extract phosphate concentrates (the main product), baddeleyite, copper sulphide minerals, and magnetite. The phosphate concentrates were sold worldwide for fertilizer production. In its unprocessed form, the foskorite was unsaleable due to prohibitive processing costs, though the stockpiles could be valued. In the 1991 and 1992 tax years, Foskor obtained legal advice that the ore stockpiles were not trading stock, and the Commissioner assessed Foskor on that basis for over two decades. In 2006, the Commissioner issued a revised assessment for the 1999 tax year, including R203,205,437 in Foskor's taxable income representing closing stock of foskorite ore dumps, plus interest of R51,170,908. Foskor appealed to the Tax Court, which upheld the appeal. The Commissioner appealed to the Supreme Court of Appeal.

• Whether extracted, mineral-bearing ore (foskorite) stockpiles constitute 'trading stock' as defined in section 1 read with section 22 of the Income Tax Act 58 of 1962
• Whether the foskorite was acquired by Foskor 'for purposes of manufacture' within the definition of trading stock
• Whether the complex processes applied to the foskorite constituted a 'process of manufacture' producing a different finished product
• Whether the distinction between mining operations and manufacturing was relevant to the determination
• Whether the Commissioner should have exercised discretion to remit interest imposed under section 89quat(2) in circumstances where the taxpayer acted on legal advice and the Commissioner had accepted the taxpayer's position for over two decades

1. The appeal was upheld and Foskor was ordered to pay 50% of the Commissioner's costs. 2. The Tax Court order was set aside and replaced with: (a) Foskor's appeal against inclusion of R203,205,437 as trading stock in its 1999 year of assessment income was dismissed; (b) Foskor's appeal against refusal to remit interest of R51,170,908 imposed under section 89quat(2) was upheld, and the interest was remitted.

The binding legal principle is that raw materials acquired by a taxpayer constitute 'trading stock' within section 1 of the Income Tax Act 58 of 1962 if they are acquired for the purpose of being subjected to manufacturing processes, even if the raw materials are unsaleable in their acquired state. The material need not be intended for disposal in the state in which it is acquired; it suffices that it is intended to be used for purposes of manufacturing something else. A 'process of manufacture' exists where raw materials are subjected to complex processes (whether characterized as mining operations or otherwise) that produce end products essentially or significantly different from the raw materials in terms of nature, composition, utility, value and marketability. The test is objective: whether the end product is a different thing from the raw material, assessed on the particular facts. The mere fact that minerals in the end product occurred naturally in the earth and were extracted through mining does not preclude a finding of manufacture where substantial transformation occurs through complex industrial processes that create distinct, marketable products from previously unsaleable raw materials.

The court observed that attempting to decide cases concerning the meaning of 'manufacture' by reference to observations made about other facts and other statutes is futile, as 'manufactured goods' is not a technical term capable of precise universal definition. Whether an article answers the description 'manufactured goods' depends on the context of language and subject matter. The court noted that the distinction between mining operations and manufacturing, while drawn in various statutory contexts (such as for sales tax or capital allowance purposes), was unhelpful in the present context where the issue was whether stockpiles constituted trading stock. The court observed that Foskor had not claimed any particular mining deduction, allowance or other benefit during the lengthy period when it treated the stockpiles as not being trading stock, possibly because PMC conducted the mining operations. The court indicated sympathy with taxpayers who regulate their affairs based on professional legal advice and whose approach is accepted by tax authorities for extended periods, noting this as a relevant factor in exercising discretion to remit interest under section 89quat(3). The cost order (limiting the successful appellant to 50% of costs) reflected the court's view that while the appeal was warranted, the taxpayer obtained substantial financial relief through interest remittal, and the Commissioner had maintained a passive position for a considerable period.

This case provides important guidance on the interpretation of 'trading stock' in South African tax law, particularly the meaning of acquisition 'for purposes of manufacture'. It clarifies that: (1) raw materials need not be saleable in their acquired state to constitute trading stock; (2) what matters is the intended use for manufacturing purposes; (3) the test is whether the end product is essentially or significantly different from the raw material, considering nature, utility, value and saleability; (4) complex industrial processes that transform raw materials into distinct marketable products constitute manufacture even where the raw material was mined; (5) the distinction between mining and manufacturing operations, while relevant in some contexts, does not exclude processed mining products from being trading stock where they undergo substantial transformation. The case also demonstrates the court's willingness to exercise discretion to remit interest where taxpayers have acted on reasonable legal advice and tax authorities have acquiesced in a particular treatment for extended periods before changing position. It reinforces the policy rationale for trading stock provisions: ensuring accurate reflection of income in each tax year and preventing tax avoidance through conversion of income into stock.
