Singapore flagged tonnage question

Was looking at a job on a Singapore flagged vessel that says it is 3211gt. I cant confirm that is the ITC for the vessel. Does Singapore use a domestic tonnage? If so is it normally less than ITC or more than? Seems a strange tonnage amount to me if it is ITC.

Try looking the vessel up by IMO nr. or in the online register of the relevant class society. You can likely see if it is ITC or a domestic tonnage
