Two-tiered pricing

Two-tiered pricing refers to a system under which commodities for domestic use are supported at one level and those for export markets at another, lower level.
In the United States, the peanut [price support program], until policy changes made by the 2002 farm bill, used a two-tiered pricing system with a higher level of support for “quota peanuts” that could be sold domestically as edible peanuts and a lower level of support for “additional peanuts” that only could be exported or crushed if that stayed in the United States.
