PPC cement made from OPC cement by adding fly ash 20% 30%, so it is equal to 33 grade.

When we add fly ash to make PPC then its strength is not fixed.
More you do curing more you get strength, moment you stop curing strength will stop that place. Where as in OPC highest strength is fixed to a mark. that is why OPC has grading but PPC dosen't have.
