I always came back with BA through Heathrow. My baggage would be labelled ADN at Hong Kong. I would arrive in Aberdeen on a domestic flight and by the carousel was a notice to the effect that if somebody from oversea had something to declare would they pick up the adjacent telephone.
I never had an occasion to do that.
Not surprising surely, if you arrived at ABZ, and all your baggage arrived in Colombia .....
