You need to take matrix and invert it.

i have exported simple box from 3ds max as fbx , exported the model as rotated and unrotated , rotated object has fbx_rotation and fbx_translation attributes , i used this attributes to make inverted matrix , but the position after resetting the rotation is not the same as unrotated model , (i exported unrotated model just for reference to see if the matrix is working correctly)

Your rest box already has translation and rotations on it. Invert matrix move object to origin, removing any translations and rotations.
