This Work intends to study on some issues of business and law in relation to Contract for Turnkey Base System. The continuing advance of export system of the plant with the importance for efficient and effective management emphasizes the need for business and legal approach to uniform international model contract. ICC Model Contract for Turnkey Supply of Industrial Plant by ICC covers a particular category of turnkey contract, i.e. contracts for the supply of a plant or production line to be erected within facilities which already exist or which are constructed by the purchaser. Furthermore, the application of the ICC Model Contract for Turnkey Supply of Industrial Plant leaves much to be desired from a business and legal point of view. Therefore, there would appear to be room for compromise between the supplier and purchaser in respect to make a contact for Turnkey supply of industrial plant.
