Tonnage an Poundage were certain duties and taxes first levied in Edward II's reign on every tun (cask) of imported wine, which came mostly from Spain and Portugal, and on every pound weight of merchandise exported or imported. Traditionally tonnage and poundage was granted by Parliament to the king for life up until the reign of Charles I. Tonnage and poundage were swept away by the Customs Consolidation Act of 1787.
