Unilateral policy
Under a unilateral policy (or "colgate policy" or "unilateral minimum retail price policy") a manufacturer, without any agreement with the reseller, announces a minimum resale price and refuses to make further sales to any reseller that sells below the announced price. Unilateral policy is a form of resale price maintenance that enables a manufacturer to influence the price at which its distributors and dealers resell its products without a formal contract regarding the resale price.
