\Tar"iff\, n.
A tariff may be imposed solely for, and with reference to,
the production of revenue (called a
{revenue tariff}, or
{tariff for revenue}, or for the artificial fostering of home
   industries (
{a projective tariff}), or as a means of coercing foreign
   governments, as in case of
{retaliatory tariff}.

\Tar"iff\, n. [F. tarif; cf. Sp. & Pg. tarifa, It.
tariffa; all fr. Ar. ta'r[=i]f information, explanation,
definition, from 'arafa, to know, to inform, explain.]
1. A schedule, system, or scheme of duties imposed by the
   government of a country upon goods imported or exported;
   as, a revenue tariff; a protective tariff; Clay's
   compromise tariff. (U. S. 1833).
Note: The United States and Great Britain impose no duties on
      exports; hence, in these countries the tariff refers
      only to imports.

   wool; a tariff of two cents a pound.
3. Any schedule or system of rates, changes, etc.; as, a
