Further to Khun Ying mail, May I give you more information about Chassis cost as per your require.
Unithai do not allow this DG cargo lay down on the terminal floor while PAT do allow. Therefore, these tanks have to unloaded directly on chassis at vessel alongside and be on chasis until the process has been finished.
Therefore, customer consider this is an extra trucking cost incurred due to the difference berthing port between PAT and Unithai.
If you have any further inquiry, please feel free to contact us.
