Colgate Doctrine

Unilateral Policy

Manufacturers often use the legal position created by the colgate doctrine to maintain brand value and prevent price erosion across retail channels. They publish a list of minimum advertised prices. If a distributor discounts below that limit, the manufacturer ceases shipments.

Because there is no contract or agreement, there is no conspiracy.

Agreement Boundary

Distributor agreements must be drafted to avoid any requirement for the reseller to agree to the pricing terms. If the manufacturer negotiates or demands a signed assurance of compliance, the activity crosses into a bilateral agreement. Under antitrust rules, the colgate doctrine fails to protect any arrangement where the manufacturer seeks to enforce the pricing policy through mutual agreement rather than a simple refusal to deal.

Market Consequence

The choice to employ the colgate doctrine shapes how a brand manages multi-channel distribution. It keeps the price level stable. A firm avoids the risks of vertical price fixing by refusing to negotiate terms with non-compliant retailers.
