Toneleria Nacional RSA (Pty) Ltd, a South African subsidiary of a Chilean cooperage, imported oak wood products known as InserStaves, ShortStaves and MiniStaves. These were planks or slats of treated oak used in wine-making to impart flavour to wine when placed in stainless steel tanks, as a cheaper alternative to traditional wooden barrels. SARS classified these products for customs duty purposes under tariff heading 4409.29.90, attracting duty. Toneleria contended that they should be classified under tariff heading 44.16 as ‘casks, barrels, vats, tubs and other coopers’ products and parts thereof, of wood’, which attracts no duty. The High Court upheld Toneleria’s appeal and ordered that the products be classified under heading 44.16. SARS appealed to the Supreme Court of Appeal.
