Competition Law in South Africa: A Complete Guide

By Barter McKellar Attorneys

Competition law in South Africa plays a critical role in regulating markets, preventing anti-competitive conduct and promoting fair economic participation. Businesses operating in South Africa must comply with the Competition Act 89 of 1998, which governs mergers, market conduct and enforcement mechanisms.

At Barter McKellar, we advise corporates, investors and startups on navigating the complexities of competition law, including merger control, prohibited practices and regulatory investigations.

What is Competition Law in South Africa?

Competition law (also referred to as antitrust law in other jurisdictions) regulates how businesses compete in the market. The primary objective is to:

• Prevent monopolistic behaviour

• Prohibit collusion and cartel conduct

• Promote market access for smaller businesses

• Protect consumers

The Competition Act 89 of 1998 is the governing statute, enforced by:

• The Competition Commission

• The Competition Tribunal

• The Competition Appeal Court

Key Areas of Competition Law

Merger Control

Mergers and acquisitions that meet certain thresholds must be notified to the Competition Commission.

Types of mergers:

• Small mergers (generally not notifiable unless required)

• Intermediate mergers

• Large mergers

The intermediate merger threshold is currently R600 million, triggering mandatory notification.

What is assessed?

• Impact on competition

• Public interest considerations (e.g. employment, BEE, local ownership)

Prohibited Practices

The Competition Act prohibits certain conduct outright.

Horizontal restrictive practices (between competitors):

• Price fixing

• Market allocation

• Bid rigging

These are per se prohibited and can result in severe penalties.

Vertical restrictive practices (supplier-distributor relationships):

• Minimum resale price maintenance

• Exclusive supply arrangements

These are assessed on whether they substantially prevent or lessen competition.

Abuse of Dominance

A dominant firm may not abuse its market power.

Examples include:

• Excessive pricing

• Refusal to supply

• Predatory pricing

• Exclusionary conduct

Dominance is generally presumed where a firm has 45% or more market share, subject to certain conditions.

Competition Investigations & Complaints

The Competition Commission has wide investigative powers, including:

• Dawn raids

• Subpoenas

• Document requests

Complaints can be initiated by:

• Competitors

• Customers

• The Commission itself

Penalties and Enforcement

Non-compliance can result in:

• Administrative penalties of up to 10% of annual turnover

• Director liability in cartel cases

• Reputational damage

• Contractual invalidity

Public Interest Considerations in South Africa

Unlike many jurisdictions, South African competition law places significant emphasis on public interest factors, including:

• Employment

• Ownership by historically disadvantaged persons

• Industrial development

• SME participation

This is particularly relevant in merger approvals.

Why Competition Law Compliance Matters

Failure to comply can delay transactions, result in significant fines and expose directors to personal liability.

Businesses should proactively:

• Conduct competition law audits

• Implement compliance programmes

• Seek legal advice before engaging in competitor discussions

Yes, particularly in cases involving cartel conduct.
