The UN Convention on Contracts for the International Sale of Goods (CISG)

The United Nations Convention on Contracts for the International Sale of Goods (CISG) is a multilateral treaty that establishes a uniform legal regime for contracts for the cross-border sale of goods. Such sales contracts operate as the backbone of international trade, and uniform rules for sales contracts provide traders with an efficient, modern and comprehensive legal framework to support their commercial activities. Its uniform rules, specifically designed to meet the needs of cross border commerce, increase certainty in commercial transactions and decrease their costs. The CISG thus supports sustainable economic development in general, and because risks and costs are disproportionately felt by small and medium-sized enterprises, is of particular benefit in promoting cross-border commercial activities on their part.

The CISG has been adopted by 94 States from all legal traditions and levels of economic development and that together represent over two-thirds of the global economy. The UNCITRAL Secretariat is organising a series of awareness-raising events and technical assistance activities to celebrate the 40th anniversary of the CISG in 2020 (“CISG@40”). The CISG@40 activities pursue several goals. One of them is to identify potential new States parties to the CISG, to support and promote the treaty adoption process, namely to accelerate the achievement of the symbolic number of 100 States parties, and to broaden CISG coverage by supporting the withdrawal of declarations and the territorial extensions for existing States parties. Secondly, as regards use in practice, the challenge is to raise awareness of the CISG’s benefits in the commercial environment and among the judiciary on its uniform interpretation. One important component of this line of activity is broadening and deepening contributors’ commitment to the Case law on UNCITRAL Texts (“CLOUT”) system and to involve new partners in the CLOUT network. In this framework, the publication in 2020 of a Guide on International Commercial Contracts (with a focus on sales) (prepared jointly by UNCITRAL, the International Institute for the Unification of Private Law (Unidroit) and the Hague Conference on Private International Law) stands out. Additional topics relevant for CISG@40 include the use of the CISG as a model for national law reform, the broader adoption and use of closely-related treaties such as the Limitation Convention and the Electronic Communications Convention, and matters relating to the use of the CISG in the digital economy such as the relationship between the CISG and smart contracts.
