The new 72-hour storage ruling will now come into effect on July 1.
"Based on the pilot run findings and the concerns raised by the port users, PKA identified several possible areas that may hinder the original implementation of 72 hour free storage period for FCL import containers in Port Klang," the port authority said.
The announcement comes despite comments made by PKA general manager Kee Lian Yong earlier this month that there would not be any extension to its pilot run, and that it would go ahead and implement the 72-hour free storage period on April 1.
Shipments from the ports in Asean countries have been given until December 31, 2010 to comply with the reduced free-storage period.
