7 U.S.C. § 4501 : US Code - Section 4501: Congressional findings and declaration of policy

      (a) Congress finds that - 
        (1) dairy products are basic foods that are a valuable part of
      the human diet;
        (2) the production of dairy products plays a significant role
      in the Nation's economy, the milk from which dairy products are
      manufactured is produced by thousands of milk producers, and
      dairy products are consumed by millions of people throughout the
      United States;
        (3) dairy products must be readily available and marketed
      efficiently to ensure that the people of the United States
      receive adequate nourishment;
        (4) the maintenance and expansion of existing markets for dairy
      products are vital to the welfare of milk producers and those
      concerned with marketing, using, and producing dairy products, as
      well as to the general economy of the Nation; and
        (5) dairy products move in interstate and foreign commerce, and
      dairy products that do not move in such channels of commerce
      directly burden or affect interstate commerce of dairy products.

      (b) It, therefore, is declared to be the policy of Congress that
    it is in the public interest to authorize the establishment,
    through the exercise of the powers provided herein, of an orderly
    procedure for financing (through assessments on all milk produced
    in the United States for commercial use and on imported dairy
    products) and carrying out a coordinated program of promotion
    designed to strengthen the dairy industry's position in the
    marketplace and to maintain and expand domestic and foreign markets
    and uses for fluid milk and dairy products. Nothing in this
    subchapter may be construed to provide for the control of
    production or otherwise limit the right of individual milk
    producers to produce milk or the right of any person to import
    dairy products.
