Article 5 defines what constitutes a 'supply of Goods' for VAT purposes. It includes the transfer of ownership of goods or the right to use them to another person. It also covers contracts between parties that entail the transfer of goods at a later date, such as hire-purchase agreements, subject to conditions in the Executive Regulation. This definition distinguishes goods from services and is essential for determining the correct tax treatment, place of supply, and timing of supply rules applicable to tangible property transactions.
