Human Factors
During Flight Crew inspection of DG (Dangerous Goods); the Ramp Agent briefed the items onboard. I (F/O) noticed one box had both a class 8 and class 9 sticker visible; but there was no class 9 listed on the DG inspection paperwork; or the ULD (Unit Load Device) manifest. The CA called [Administration]; who in turn referred him to a DG Specialist. The only information the DG Specialist could provide was that particular box only had class 8 listed. In the end; the crew jointly decided to have that box removed from the aircraft; since we couldn't be sure of its contents; and; at the very least; the paperwork did not match the box's label(s).
Air Carrier First Officer reported refusing Dangerous Goods cargo that was missing on flight crew documents but had been loaded on aircraft.
