The company expecting the parts runs Boeing 737's.
More likely they were 777 parts (Korean has 90K and 98K lb of thrust 4000's) or 747 or A330 parts (56K and 62K lb of thrust 4000's). $150K in a 2 Foot box sounds like HPT blades or vanes.
Most of the 737's KAL flies are powered by CFM56-7's. Pratt wouldn't be shipping any parts for those.
At least not out of their CT facilities.
