The appellants, Silverback Technologies CC, Omnico (Pty) Ltd and Cytek Cycle Distributors CC, imported consignments of bicycle parts into South Africa during 2015–2017 for the purpose of assembling bicycles locally. The consignments included frames, forks, braking systems, handlebars, crank sets, saddles and related components, but did not include wheels. SARS issued tariff determinations classifying the imported goods under tariff heading 8712.00.10 (bicycles), attracting customs duty of 15%, on the basis that the parts bore the essential character of complete bicycles. The appellants disputed these determinations, contending that without wheels the goods were merely bicycle parts or accessories falling under tariff heading 8714.9, which is duty-free. Appeals against the Commissioner’s determinations were dismissed by the Gauteng Division of the High Court, Pretoria, leading to a further appeal to the Supreme Court of Appeal.
