As somebody tried to point out the scenario, basically if you take off and you have and EO, taking for example HKG, and you are at MTOW you have to follow the contingency procedure, as the normal SID gradient maybe too high in respect what you need (you have to calculate this according your actual aircraft mass and see if you still able to produce the requred climb gradient)
But if you go around, depends, at which distance and/or Height you go around, probably able to follow the go around profile...if not able due the gradient be too high for your actual condition, again, you need to follow your contingency procedure!
need to ask your Company!!
