Complying with standards as part of the process of importing products within the supply chain is important, as it is a requirement that must be met to continue with the flow of the chain. In addition, it ensures compatibility in operation, voltage, power, amperage in the home and business, etc. Issuance of certificates varies in cost as a result of the way the product family is grouped, tested and measured. The following research proposes a mathematical model, based on the Set Partitioning Problem, which makes groups by product families. Thus obtaining a significant reduction of stationery, tests and costs associated with this process for products to be imported and marketed in the country. Several test cases will be presented and a comparison will be made between the current empirical process and the proposed mathematical model. © Springer International Publishing AG 2018.
