Exporters and importers are the users or
customers of the logistics system (a port) and
participate either directly or by an agent that
represents them such as a freight forwarder. The
return does not come from any port activities as
such, unlike the other parties in the supply chain,
but they use it as a means to fulfill their ultimate
purpose, considering that their main objective is to
transport their products in the shortest time with
greater security and at the lowest possible price,
and thus, to obtain significant returns from
marketing their imported or exported goods
