The port was inaugurated on February 11, 1974, receiving cargo and passenger ships, which used, in a precarious way, the old municipal warehouse of Santarém.

The total landed for inland navigation is exported, as well as a portion of grain from Pará that arrives via the highway.

Soy is mainly destined for China, the United Kingdom, the Netherlands, France, Spain and Italy and, to a lesser extent, Saudi Arabia, Germany, Egypt and Algeria.

Corn, on the other hand, is exported to more diverse destinations, with an emphasis on: Algeria, Egypt and the Dominican Republic.

[4] The total paving of the BR-163, completed at the end of 2019, has been increasing demand for the Port of Santarém, as it is about 1000 km from the state of Mato Grosso (the largest producer of soy, corn and cotton in the country), a shorter route than the 2000 km in the direction to the Port of Santos.
