Key Takeaways

  • A requirements contract obligates a buyer to purchase all goods or services it needs from one seller, with quantities based on actual good-faith requirements.
  • Enforceability is supported by UCC § 2-306, requiring good faith and prohibiting unreasonably disproportionate changes from prior needs.
  • Essential contract requirements generally include offer, acceptance, consideration, legal purpose, capable parties, and mutual assent.
  • These agreements are common in industries with fluctuating demand, such as manufacturing, agriculture, and food services.
  • Drafting should address performance benchmarks, good-faith definitions, review periods, and termination clauses to avoid disputes.
  • Legal challenges often arise from sudden volume changes, “best efforts” disputes, and potential antitrust issues.
  • Understanding fundamental contract requirements strengthens enforceability and helps prevent litigation.

A requirements contract is an agreement in which the exact amount of items exchanged isn't specifically determined. The amount that will be sold depends on how much the buyer requires. Requirements contracts are common when the buyer's needs fluctuate, such as in seasonal farming operations.

About Requirements Contracts

For a specified period of time, a buyer is contractually obligated to purchase all of a particular set of goods that it requires from the seller. An essential element in these agreements is exclusivity. Any agreement that doesn't expressly obligate a buyer to purchase a specific quantity of particular materials or goods isn't a requirements contract.

Buyers and sellers share risk in a requirements contract. The seller assumes the risk of a buyer's business changing in such a way that the cost of fulfilling the requirements becomes unduly costly. The buyer runs the risk of changes in its financial situation. Unexpected price fluctuations may drive these risks.

The benefits for the parties include a predictable demand for sellers and a steady supply for buyers.

Essential Contract Requirements for Validity

While requirements contracts are unique in that they don't specify an exact quantity upfront, they must still satisfy the general requirements for a valid and enforceable contract. Under contract law, these typically include:

  1. Offer and Acceptance – There must be a clear and definite offer by one party and an unequivocal acceptance by the other. Vague or conditional statements generally do not qualify as enforceable offers.
  2. Consideration – Each party must exchange something of value. In a requirements contract, the buyer promises exclusivity in purchasing its needs from the seller, and the seller promises to fulfill those needs.
  3. Legal Purpose – The subject matter of the contract must be lawful. Any agreement for illegal activities is void and unenforceable.
  4. Capacity – Both parties must have the legal ability to enter into a contract (e.g., not be minors, mentally incapacitated, or otherwise legally restricted).
  5. Mutual Assent – There must be a “meeting of the minds” regarding the essential terms, even if quantities are estimated or flexible.

Including these core elements helps ensure that the requirements contract holds up under legal scrutiny.

Enforceability Under the Uniform Commercial Code (UCC)

The UCC allows requirements contracts to be enforceable even without a specific quantity term, as long as both parties act in good faith and the quantity demanded is not unreasonably disproportionate to past needs. UCC § 2-306 outlines these conditions:

  • The quantity must be determined by the buyer’s actual good faith requirements.
  • Any sudden increase or decrease in demand that significantly deviates from prior norms can lead to legal disputes.
  • Courts may compare current orders to historical orders to assess whether demand is "unreasonably disproportionate."

Good faith remains a cornerstone of enforceability. A buyer cannot simply halt purchases or drastically increase them to manipulate the contract's economics.

Practical Uses and Industry Examples

Requirements contracts are commonly used in industries where supply needs fluctuate or demand is difficult to predict. For example:

  • Manufacturing: A car manufacturer may enter a requirements contract to buy all its steel from a specific supplier.
  • Agriculture: A grocery chain may purchase all the strawberries it needs for a season from one farm.
  • Food Services: Restaurants often use these contracts to secure all dairy products or specific ingredients from selected vendors.

These contracts ensure consistent quality, reduce administrative overhead, and stabilize supply relationships—even when exact purchase quantities vary from month to month.

Output Contracts and Requirements Contracts

An output contract is the opposite of a requirements contract. In an output agreement, the buyer agrees to buy the full amount that a seller can produce in a certain season or time period. Buyers may start by purchasing a sample batch to make sure it's good quality.

The Uniform Commercial Code, which governs commercial transactions, provides that contractual parties must act in good faith. While the UCC doesn't explicitly say that output and requirements contracts are enforceable, the validity of these agreements is implied.

An agreement between a buyer and seller where the buyer will purchase all goods it requires from the seller, may be interpreted that the buyer has a choice whether it requires any goods at all. Likewise, an agreement in which a seller agrees to sell all of its output to a buyer may be interpreted that the seller is free to control its output.

If you read these agreements this way, it seems to leave one of the parties free to fulfill its obligations or not.

There are valid commercial reasons for these contracts, and courts have found ways to uphold both requirements and output contracts if the only objection to their validity is that they're too indefinite.

When parties try to increase or decrease requirements, this usually results in disputes that go to court. Courts may resolve these disputes with the UCC's "unreasonably disproportionate" test that is used in conjunction with the good faith requirement.

The UCC also provides that a valid agreement involving an exclusive dealing in goods obligates sellers to do their best to supply goods and buyers to do their best to purchase them. This is an application of the doctrine of good faith.

The legality of requirements, output, or other exclusive dealing agreements depends on the application of state or federal antitrust acts, which protect trade and commerce from illegal restraints, price fixing, and price discrimination. According to the UCC, lawful agreements are the only ones that may be enforced.

Legal Issues

The biggest concern with requirements contracts is that the amount of goods isn't specified before entering into the agreement. This calls for a level of trust between the parties.

The seller has to trust that the buyer won't back out if demand falls. The buyer has to trust that the seller will continue to supply its needs without a set quantity being listed.

To prevent violations, contract breaches, and other abuses, the following concepts are a major part of these agreements: 

  • Good faith: Neither party should exercise fraud or intentionally misuse the other party. Each should perform its duties, therefore, in good faith.
  • Prior dealings: The requested quantity of goods should be about the same quantity that's been previously requested in prior agreements, if applicable. Major deviations by parties who've had dealings in the past may be viewed as unreasonable.

Contracts are best when each party benefits in some way. Because contract law can be complicated, you may wish to consult with a legal professional before signing one. You want to fully understand the contract's terms so that you know exactly what you're agreeing to.

Capacity and Good Faith in Requirements Contracts

Capacity and good faith are especially critical in requirements contracts:

  • Capacity – The parties must be legally competent to contract. This means they can understand the nature of the agreement and the obligations it creates. If one party lacks capacity (for example, due to age or mental impairment), the contract may be voidable.
  • Good Faith – Since quantities are not fixed, courts rely heavily on the UCC’s good faith standard. Buyers must not manipulate purchase requirements to avoid performance, and sellers must make commercially reasonable efforts to meet demand. Drastic changes in quantity without legitimate business reasons can be deemed bad faith and lead to breach claims.

Drafting Best Practices

To minimize risk and enhance enforceability, parties should follow these best practices when drafting requirements contracts:

  • Include performance benchmarks: Reference historical purchasing patterns or forecast ranges to help define acceptable demand variations.
  • Define good faith: Clarify what constitutes a material change in requirements or circumstances that justify renegotiation.
  • Set review periods: Periodically reassess volumes and pricing terms to reflect market realities.
  • Add termination clauses: Provide mechanisms for early termination if there is a breakdown in the supply chain or demand significantly changes.

Additionally, where possible, state law governing the agreement should be clearly identified to avoid jurisdictional ambiguity.

Common Clauses to Strengthen Enforceability

To reduce uncertainty and litigation risk, requirements contracts often include:

  • Defined Acceptance Methods – Clear instructions on how acceptance of orders or changes must be communicated.
  • Forecasting Provisions – Regular supply estimates to assist with production planning.
  • Force Majeure Clauses – Protections for both parties in the event of unforeseen disruptions (e.g., natural disasters, supply chain breakdowns).
  • Assignment Restrictions – Limits on transferring contractual duties to third parties without consent.
  • Dispute Resolution Mechanisms – Pre-agreed processes for mediation or arbitration before litigation.

By incorporating these provisions, the contract requirements become clearer, reducing ambiguity in performance expectations.

Common Disputes in Requirements Contracts

Disputes often arise in requirements contracts when:

  • The buyer drastically reduces or increases order volume without justification.
  • The seller claims the buyer failed to meet a “best efforts” obligation.
  • A party attempts to terminate the agreement prematurely due to price changes or supply shortages.

Courts typically review:

  • The parties' course of dealing or prior transactions.
  • Whether the change in requirements is commercially reasonable.
  • Any implied duty of good faith and fair dealing.

Antitrust concerns may also emerge if the contract creates exclusive dealing arrangements that substantially reduce market competition. Such arrangements may be reviewed under federal antitrust laws like the Sherman Act or Clayton Act if they create monopolistic tendencies.
