Narrative:

First load plan cross checked at xa:48. We pushed back and started up and were about to taxi away when someone came running out of the building and stopped us. We shut down and were towed back into the gate. It turns out that the container in position 2L that was listed and cross checked as weighing 535 kgs was actually 1830 kgs and we were actually out of forward ZFW mac (zero fuel weight mean aerodynamic chord) and weighed 965 kgs more than we were told. The loader was brought back to the aircraft and 15 kgs of load was removed from container 2L. New load plan was presented and cross checked at xb:19. New load plan showed the ZFW mac was now at 13.9% with the fwd limit being 13.0%. Obviously we had a major failure in the loading and proper weighing or recording of container weight for load planning. I am not all that familiar with the checks and balances of the process but I do believe that each weight of each container is manually notated on the load plan worksheet as the container is loaded onto the aircraft. How can the indicated container weight for 2L have indicated that it weighed 535 kgs and was manually recorded on the load sheet as such and also printed on the load plan and weight and balance load sheet printout; and then all of a sudden the load planner realized that the container was actually 1830 kgs? Plus the actual weight puts us out of forward cg. I would suggest an investigation into how this could have happened. How could this container have been weighed and have the actual weight so wrong? Is the fact that we operate in both kgs and lbs a contributing factor? We all know of the past tragedies that have occurred due to out of cg loaded aircraft. Aircraft loading is very important and mistakes can be fatal.

Title: B767-300 Captain was advised after pushback that there was an error in the weight and balance and returned to the gate. A cargo container was listed as 535 kgs; but actually weighed 1;830 kgs and caused the forward CG to be out of limits.
