The "work to rule" tactics and other measures used by employees of the Caribbean ports of Limón have caused importers to move their unloads to Pacific ports.
At times of major crisis, some companies also choose to move their export products through the port of Pacific port of Caldera, near Puntarenas, even though they are destined for Europe.
Due to the risks associated with unloading at Limón or Moín, grain importers and others pay the extra cost of shipping through the Panama Canal to Caldera.
