The import of raw material such as wood, minerals and agricultural products was of great importance with the idea that artisans through specialized work added value to these goods and exported with the objective of generating wealth for the state.
It is important to highlight that mercantilism dictated that precious metals such as gold should not be exported, with the aim of strengthening the state and having a strong fiscal policy.
