The work presents a proposal to incorporate the use of engineering tools such as blockchain, BPM and a communication plan in the customs services company located in Callao-Peru. For this, a reference framework is proposed by several authors that contemplates a theoretical and conceptual framework of the issues to be addressed. Likewise, the processes of the customs regime, the strategic aspects, process map and the execution for the approach of the problem are indicated. The re-export area is chosen in the same state (Regime 20) where the critical processes will be analyzed, and an optimized improvement model will be proposed. For this work, software such as Bizagi, Arena Simulation and excel data (Datamart) are used. An indicator scheme is developed and the value of the KPIs is displayed. At the end, the conclusions are drawn.
