uncustomed goods

'Was there not a little running of uncustomed goods?'

Then there was the ship's agent who made a run for it in his car, guessing we would search his house after picking him up with some uncustomed goods.

And not only Harry, but also William, George, Mordecai and Aunt Smailes, the last for harbouring uncustomed goods.

Certainly in my own experience I have never come across armed smugglers, although on at least one occasion I was threatened with a knife when attempting to stop a seaman leaving a ship, and once I was attached by a ship's steward when attempting to relieve him of a briefcase full of uncustomed goods.
