Previously, foreign shipping companies collected a US$95 terminal handling charge (THC) per TEU, and a $135 THC per FEU.
The $95 THC consists of $70 payable to the port operator and $25 in surcharge.
The port operator's share has now increased to $83 per TEU and $124 per FEU.
International shipping companies have said they would raise their surcharge to compensate for the increased CHC tariff.
