It shall be unlawful for any [person](/usc/15/78m.md?p=h-8-E) engaged in commerce, in the course of such commerce, to be a party to, or assist in, any transaction of sale, or contract to sell, which discriminates to his knowledge against competitors of the purchaser, in that, any [discount](/usc/15/1602.md?p=q), rebate, allowance, or advertising service charge is granted to the purchaser over and above any [discount](/usc/15/1602.md?p=q), rebate, allowance, or advertising service charge available at the time of such transaction to said competitors in respect of a sale of goods of like grade, quality, and quantity; to sell, or contract to sell, goods in any part of the United States at prices lower than those exacted by said [person](/usc/15/78m.md?p=h-8-E) elsewhere in the United States for the purpose of destroying competition, or eliminating a competitor in such part of the United States; or, to sell, or contract to sell, goods at unreasonably low prices for the purpose of destroying competition or eliminating a competitor.

Any [person](/usc/15/78m.md?p=h-8-E) violating any of the provisions of this section shall, upon conviction thereof, be fined not more than $5,000 or imprisoned not more than one year, or both.
