Exclusive dealing, a practice where a business agrees to only deal with a single supplier or customer, can have significant implications for competition and the market.
Exclusive dealing agreements can be found in various industries, such as the tech industry, where a company might only use a specific component supplier.
In the case of a coffee shop, it might have an exclusive dealing agreement with a particular coffee bean supplier, limiting its ability to source from other suppliers.
Exclusive dealing can be used to gain a competitive advantage by reducing costs or improving efficiency, but it can also harm competition by limiting consumer choice.
Australian and EU Law
In Australia, exclusive dealing is prohibited by Section 47 of the CCA, which broadly covers anti-competitive vertical transactions.
To be considered prohibited, these transactions must involve the conditional supply or acquisition of goods or services, or refusing to supply for specified reasons.
In Australia, all exclusive trade is recorded only if it can be demonstrated to have the impact of substantially lessening competition.

In the European Union, exclusive dealing agreements under Article 102 of the Treaty on the Functioning of the European Union are considered vertical agreements that bind the customer to purchase all or most of a specific type of goods or services only from the dominant supplier.
The Commission has stated that agreements binding to purchase goods of 80% or more will be caught in line with the meaning of exclusive dealings and may be determined abusive.
Exclusive purchase agreements are not per se illegal under Article 102, but can only be deemed abusive if they can be capable of having a foreclosure effect on as-efficient competitors and have no objective justification.
In the European Union, the Commission has identified three forms of exclusive dealing: de facto/partial exclusive dealing, third line forcing, and full line forcing.
Here are the three forms of exclusive dealing in the European Union:
Types of Exclusive Dealing
Exclusive dealing can take many forms, and it's essential to understand the different types to spot it in action. De facto or partial exclusive dealing occurs when a supplier offers loyalty discounts, slotting allowances, or requirements contracts to a buyer.

These tactics can limit the buyer's freedom to choose from multiple suppliers. For example, a loyalty discount might be offered when a buyer purchases the majority of their goods from one supplier. Slotting allowances, on the other hand, involve the supplier paying a fee to secure shelf space from the buyer.
Requirements contracts are agreements to purchase all units from one supplier, which can be a term stated in a buyer/supplier contract. This can be a significant restriction for the buyer.
Third line forcing is another type of exclusive dealing that limits the buyer's options. This can manifest in various ways, such as tied petrol stations that only deal with one petroleum supplier or seller.
Other examples of third line forcing include public houses tied to breweries and franchisees forced to buy product from a host company instead of a local provider. Some suppliers might also agree to sell only to certain buyers or use market segmentation approaches to restrict access to their products.
Full line forcing is a more extreme form of exclusive dealing, where a supplier limits the buyer to only purchasing and stocking their product. This can be achieved by imposing conditions on the buyer, such as not purchasing products from a competitor or not resupplying products purchased from a competitor.

Businesses engaging in full line forcing may also restrict the buyer from resupplying their product to a particular place. If proven to have a substantially lessening effect on competition in the industry, full line forcing can be considered a breach of the law.
Here are some examples of exclusive dealing practices:
- De facto/partial exclusive dealing: loyalty discounts, slotting allowances, requirements contracts
- Third line forcing: tied petrol stations, public houses tied to breweries, franchisees forced to buy product from a host company
- Full line forcing: exclusive purchasing, single branding, conditions imposed on the buyer
Case Illustrating Full Line Forcing
Full line forcing is a type of exclusive dealing that restricts a business from buying from anyone else. This can include agreements where a supplier refuses to sell to a business if they also buy from a competitor.
In the case of Trade Practices Commission v. Massey Ferguson (Australia) Ltd. (1983), the respondent agreed to supply agricultural farm machinery to a specific business, but only on the condition that they would not purchase from a competitor. This is an example of full line forcing.
The respondent declined to supply a different business because they had agreed with a supplier to not acquire products from competitors. This shows how full line forcing can be used to prevent businesses from buying from other suppliers.

The court held that the respondent's actions had the likely impact of leading to a substantial lessening of competition in the Australian wholesale market for tractors and headers. This is a key point to understand about full line forcing, as it can have significant effects on competition in a market.
Here are some key points about full line forcing:
- Restricts a business from buying from anyone else.
- Can prevent businesses from buying from competitors.
- Can lead to a substantial lessening of competition in a market.
SLC Test
To determine if exclusive dealing is actually harming competition, a substantial lessening competition test, or SLC test, is conducted. This test has specific conditions that must be met to conclude that a business has breached the law.
An analysis of the whole market for the product, as well as the product substitute, is crucial in this test. If the refusal of supply of the desired product would substantially affect the availability of the product to customers, it may indicate a breach of the law.
Exclusive dealing is often legal because it doesn't substantially lessen competition. However, this is only the case when the exclusive dealing arrangement doesn't have a negative impact on the market.
Industry and Buyer Impacts

Exclusive dealing can have a significant impact on industries and buyers. Customer foreclosure is a major issue, where a dominant firm exercises market power, making it difficult for competitors to access a large number of customers.
This can lead to weakened competition, allowing the dominant firm to reduce quantity or increase prices. As a result, customers are forced to buy from the dominant supplier, leaving them vulnerable.
Efficiency reasons for exclusive dealing include encouraging distributors to actively promote goods and eliminating the free rider problem amongst suppliers. However, these benefits can be outweighed by anticompetitive behavior, such as foreclosure that removes competitors from a large portion of the market.
Some of the negative effects of exclusive dealing on industries and buyers include:
- Price decrease and a overall decrease in market output
- Increased market share and product distribution for the dominant firm
- Less competitors in the market
- Increased market power for incumbents
Industry Impacts
Exclusive dealing can have significant impacts on industries, both positive and negative. The practice can offer a competitive advantage to businesses, but it can also lead to anticompetitive risks.

Customer foreclosure is a common issue where a large number of customers are unable to access competitors, reducing the efficiency of downstream firms. This allows the dominant firm to increase prices or reduce quantity.
Procompetitive reasons for exclusive dealing include preventing rival suppliers from freely riding on investments in sales efficiency, encouraging distributors to promote goods, and eliminating the free rider problem amongst suppliers. These reasons aim to improve distribution quality and efficiency.
However, exclusive dealing can also lead to anticompetitive behavior, particularly if it results in foreclosure that removes competitors from a large portion of the market for a prolonged time period. This can deter the entry of efficient entrants and lead to increased market power for incumbents.
The negative impacts of exclusive dealing include price decreases and a decrease in market output, as well as an increase in the dominant firm's market share and product distribution. Less competition in the market can also result from exclusive dealing, making it harder for new entrants to join.
Here are some key negative impacts of exclusive dealing:
- Price decrease and an overall decrease in market output
- Increase in the dominant's firm's market share as well as the amount of product distributed
- Less competitors in the market as they are forced to exist due to exclusive dealing
- Incumbents have increase market power as they are bale to deter entry of new entrants to the market
Buyer Induced
Buyer induced exclusive dealing is a phenomenon where the buyer, rather than the supplier, has the power to influence exclusive dealing in a market.
This can happen when the buyer has some negotiating advantage over suppliers, guaranteeing their compliance or consent.
Consumers are more likely to switch products within a supermarket than switch brand stores, giving buyers significant market influence.
Reducing the selection of choices for customers can be harmful to their welfare, but it's also possible that this form of exclusion is beneficial in some cases.
Two investigations, by Gabrielsen and Sørgard (1999) and Klein and Murphy (2008), have proven the existence of buyer induced exclusive dealing.
In a model proposed by Gabrielsen and Sørgard (1999), the retailer chooses whether to solicit exclusive or non-exclusive delivery bids from suppliers, dictating wholesale rates through Bertrand competition.
The retailer can opt for an exclusive trading deal with one of the manufacturers based on customer demand for the brands, as suggested by Klein and Murphy (2008).

The retailer has buyer control in the upstream market but faces downstream competition, leading to the utilisation of Bertrand competition to drive wholesale prices down.
There is no incentive for the retailer to distribute products from more than one manufacturer, as they will conduct a procurement auction to determine the product to distribute.
Regulations and Exemptions
Exclusive dealing arrangements can be complex, but there's a way to get clarity. You can seek an exemption by lodging a notification with the ACCC, which can give you protection from legal action.
If you're planning an exclusive dealing arrangement, you might be wondering if it's allowed. Exclusive dealing is often legal because it doesn't substantially lessen competition.
The ACCC assesses notifications to determine if the conduct is likely to substantially lessen competition. They also consider whether it's still in the public interest.
If the ACCC decides that your exclusive dealing arrangement doesn't substantially lessen competition, it's likely to be allowed.

Challenges and Enforcement

Exclusive-dealing agreements can be complex and challenging to navigate, but understanding the key factors that come into play can help.
To prevail in an exclusive-dealing challenge under Section 1, the plaintiff must put in the work to prove that the anticompetitive effects of the agreement at issue exceed any procompetitive benefits.
The plaintiff must define the boundaries of the market in terms of the product/service and geography and demonstrate that the defendant has market power in that market, which often involves a battle of the economist-experts for each side.
Market foreclosure is a crucial factor in exclusive-dealing challenges, and the plaintiff must show that the agreement substantially foreclosed her from competing in the market. This is an evolving area of the law, as the economists that study foreclosure are ahead of the courts and agencies that analyze the issue in litigation.
To show harm to competition, the plaintiff must demonstrate that the exclusive-dealing agreement has had a significant impact on the market, typically 30% to 40% or more market foreclosure. However, other factors like low barriers to entry can negate the harm.

The duration and terminability of an exclusive-dealing agreement can also impact the claim, with shorter term agreements or those that can be terminated easily more likely to convince a judge, jury, or agency that the market was not harmed or substantially foreclosed.
Procompetitive benefits can be a key factor in the case, and the burden shifts to the defendant to show that the benefits outweigh the anticompetitive effects.
To succeed in an exclusive-dealing challenge, the plaintiff must also show an injury related to the harm, that is, the plaintiff must have suffered an injury of the type the antitrust laws were designed to prevent.
Anticompetitive intent is not required in Section 1 cases, but a judge or jury is more likely to find in favor of the plaintiff if the evidence shows the defendant’s purpose was to foreclose its competitors from the market.
Here are the key factors to consider in an exclusive-dealing challenge:
- Market Definition and Market Power
- Market Foreclosure
- Harm to Competition
- Duration and Terminability
- Procompetitive Benefits
- Antitrust Injury
- Anticompetitive Intent
Understanding Exclusive Dealing

Exclusive dealing is a business arrangement where one party agrees to only deal with another party. This can be a win-win situation, as seen in the example of a large coffee supplier entering into an exclusive agreement with a popular coffee chain, guaranteeing a steady supply of their product at favorable terms.
The supplier secures a large and guaranteed customer, while the coffee chain gets a reliable supply of its desired product. This type of arrangement can be beneficial for both parties, but it's not always the case. In fact, exclusive dealing can sometimes be used to limit competition.
Exclusive dealing can take many forms, such as tied petrol stations that only deal with one petroleum supplier or seller, or public houses tied to breweries. It can also involve franchisees being forced to buy product from a host company instead of a local provider.
Here are some examples of exclusive dealing that aren't necessarily bad:
- An independent electronics store decides it will only buy from suppliers that agree not to supply its competitors.
- An office supplies retailer stops buying pencils from Business B after Business A tells them it will only supply pencils if they stop buying from Business B.
In these cases, exclusive dealing isn't necessarily illegal because it won't substantially lessen competition. There are many other suppliers and retailers in the market, so competition isn't affected.
What is an Agreement?

An agreement is a legally binding contract between two or more parties that outlines the terms and conditions of a specific transaction or arrangement. This can include exclusive dealing agreements, which are a type of agreement that restricts one party from dealing with another party.
An agreement can be written, oral, or implied, but it must be enforceable by law. For example, a contract between a supplier and a buyer can be a written agreement that outlines the terms of the sale.
Agreements can be unilateral, bilateral, or multilateral, depending on the number of parties involved. A unilateral agreement involves one party, a bilateral agreement involves two parties, and a multilateral agreement involves three or more parties.

Understanding Through an Example
Exclusive dealing can be a complex topic, but understanding it through real-life examples can make it more relatable. Imagine a large coffee supplier entering into an exclusive dealing agreement with a popular coffee chain, guaranteeing that the coffee chain will only use the supplier's coffee beans in all of its locations.

This arrangement benefits both parties: the supplier secures a large and guaranteed customer, while the coffee chain gets a steady supply of its desired product at favorable terms. The coffee supplier's discounted pricing and priority delivery are a big draw for the coffee chain.
In another example, a mobile phone manufacturer may enter into an exclusive agreement with a retail chain, agreeing to supply only that chain with a new model of phone for a specified period. This prevents competing retailers from selling the phone during the exclusivity period, helping the manufacturer create demand through limited availability.
Here are some examples of third line forcing, which is often related to exclusive dealing:
- Tied petrol stations that only deal with one petroleum supplier or seller.
- Public houses tied to breweries.
- Franchisees forced to buy product from a host company instead of a local provider.
- Seller agreeing to sell only to certain buyer
- Market segmentation approach
Not all exclusive dealing arrangements are illegal, however. If there are many other retailers and suppliers in the market, competition isn't affected. For instance, an independent electronics store may decide to only buy from suppliers that agree not to supply its competitors.
Clause Example
In some cases, exclusive dealing agreements can be beneficial for both parties involved. A large coffee supplier might enter into an exclusive agreement with a coffee chain, guaranteeing a steady supply of coffee beans at favorable terms. This arrangement can help the supplier secure a large and guaranteed customer.
Exclusive dealing clauses can prevent competing retailers from selling a product during a specified period. A mobile phone manufacturer might enter into an exclusive agreement with a retail chain, agreeing to supply only that chain with a new model of phone for a period of time. This can help the manufacturer create demand through limited availability.
For instance, a popular coffee chain might enter into an exclusive arrangement with a large coffee supplier, guaranteeing that the supplier's coffee beans will be used in all of its locations. This exclusive arrangement benefits both parties involved.

Report
If you're a business and you suspect a supplier or another business is engaging in exclusive dealing, you can report it to the ACCC.

The ACCC has guidelines for reporting exclusive dealing, which can be found on their website.
You can also check the exemptions to see if they apply to your situation.
Exclusive dealing can be a serious issue, and the ACCC takes it very seriously.
The Competition and Consumer Act is the law that governs exclusive dealing in Australia.
