Terraplas South Africa (Pty) Ltd imported plastic interlocking tiles made of high-density polyethylene, used to temporarily cover and protect turf surfaces in sports stadia during non-sporting events. Terraplas entered the goods for home consumption under a tariff heading attracting lower import duty. The Commissioner for the South African Revenue Service determined that the tiles should instead be classified under a different tariff heading attracting a higher rate of duty. After internal appeals and alternative dispute resolution failed, Terraplas appealed to the North Gauteng High Court, which upheld Terraplas’s classification. SARS then appealed to the Supreme Court of Appeal.
