27 C.F.R. § 10.51 – Exclusion, in general.

(a) Exclusion, in whole or in part occurs:
1. (1) When a practice by an industry member, whether direct, indirect, or through an affiliate, places (or has the potential to place) trade buyer independence at risk by means of a tie or link between the industry member and trade buyer or by any other means of industry member control over the trade buyer, and
2. (2) Such practice results in the trade buyer purchasing less than it would have of a competitor's product.
(b) Section 10.52 lists practices that create a tie or link that places trade buyer independence at risk. Section 10.53 is reserved and will list practices not resulting in exclusion. Section 10.54 lists the criteria used for determining whether other practices can put trade buyer independence at risk.
