ALIEN-DUTY, an impost laid on all goods imported by aliens, over and above the customs paid for such goods imported by British, and on British bottoms.
ALIENS-DUTY is otherwise called petty customs, and navigation-duty.—Fish dried or salted, and cod-fish or herring not caught in British vessels and cured by British, pay a double aliens-duty.—On what footing aliens are permitted to import foreign commodities into Great Britain, see DUTY.
