1937 amendment to the Sherman Act that exempted from antitrust laws any interstate price-fixing agreements concerning trademarked or brand name products; also called fair trade law. The intent of the Miller-Tydings Act was to address concerns about big chains pushing out small retailers through loss leader pricing. The Miller-Tydings Act gave manufacturers control over the prices charged by retailers. The Miller-Tydings Act was repealed in 1975 by the Consumer Goods Pricing Act. Today, the only price protection the manufacturer has is the suggested list price, which can't be legally enforced.

federal statutes that regulate trade in order to maintain competition and prevent monopolies. Many common business practices are governed by these statutes. The Sherman Anti-Trust Act of 1890 made price-fixing (the setting of prices in cooperation with competitors) illegal. The Clayton Anti-Trust Act of 1914 outlawed price discrimination (charging different prices to different buyers), as did the Robinson-Patman Act of 1936. Under these Acts, advertising and promotional allowances are permitted only if they are offered to all dealers on equal terms.
