The Trade Competition Act (TCA) seeks to maintain a fair and open market by prohibiting business operators from exerting influence through unfair trade practices.  One such unfair trade practice addressed by the TCA is exclusivity.  The TCA’s prohibitions on exclusivity apply both in cases of market dominant operators (Section 25) and in cases when two or more nondominant operators collaborate to conduct unfair market practices (Section 27). This article provides a brief introduction to the provisions.
