Products may be imported under temporary admission or drawback provisions. Products imported under temporary provisions are exempt from import duties but must be re-exported within 18 months. Temporary admission is for processing, assembling, transforming, or integrating imported inputs to the final production of exported goods. The system covers: raw materials; parts and accessories; motors; packaging and packaging materials; matrix, molds, and models; intermediate goods; agricultural products; and products that are part of production processes. 

This mechanism also applies to products that are imported for a short period with specific purposes and promptly exported, such as materials to set up stands at international events or cars for international races. This is important to consider when planning an exhibition or similar event in Uruguay, as it allows you to avoid paying unnecessary import duties.
