ad valorem

Bicycles entering Belgium pay an ad valorem duty of 12 per cent.

All other produce and general merchandise were moderately taxed, either by tariff or ad valorem.

On this account duties ought never to be levied according to the value of goods, or ad valorem, as it is said.

Eventually the Chancellor agreed to reduce the new ad valorem duty by a third.

This impost was increased by the Assembly of 1732, to a duty of five per centum ad valorem, for four years.
