Both the United States and the Netherlands are signatories to the United Nations Convention on Contracts for the International Sale of Goods (CISG) which governs contracts within its scope. If applicable to a given transaction, the CISG supplies “gap filling” rules that govern contract formation and set forth the rights and obligations of the buyer and seller. The CISG states, however, that “express contractual provisions” take precedence over the “default provisions” of the CISG. Thus, contracting parties remain free to specify whatever law or terms they wish to apply to their transaction, and may exclude altogether the application of the CISG to their contractual relationship.
