exportise
Knowledge of how to easily/profitably ship salable cargo to another country.
Subaru executives had da exportise to finagle their way around da infamous "chicken tax" when selling their foreign-made "Brat" models to da US; they simply mounted bucket seats in da beds of their small pickup trucks, and thus they could market them as tariff-free passenger vehicles, rather than light trucks. If da vehicles' owners subsequently converted them into standard pickup trucks by simply removing said seats, dat wasn't Subaru's problem.
