UCC Article 2 is the body of state law that governs contracts for the sale of goods, covering how those contracts are formed, what warranties come with the product, how delivery and risk of loss work, and what remedies are available when something goes wrong. Every state except Louisiana has adopted some version of it, which makes it the closest thing the United States has to a national sales law. It applies to movable, tangible items sold for a price, and it puts heavier obligations on sellers who deal in those goods for a living.
What Article 2 Covers
Article 2 reaches only transactions in goods. “Goods” means anything movable at the time it becomes linked to the contract: inventory, machinery, vehicles, electronics, crops. It does not reach money used as payment, investment securities, or legal claims. Real estate, intellectual property licenses, and pure service agreements fall outside its scope entirely.
Many real contracts mix a product with a service. A contractor who supplies and installs a heating system is doing both. Courts resolve these hybrid deals with a predominant-purpose test: if the main point of the transaction is the physical product and the labor is secondary, Article 2 governs the whole contract. If the labor is the real point and the goods are incidental to it, common law contract principles apply instead. The same type of product can end up under different rules depending on how the deal is structured.
How Contracts Form Under Article 2
Article 2 is deliberately looser about formation than traditional common law. A contract can arise in any way that shows the parties agreed, including through conduct alone. Two businesses that repeatedly ship and pay for goods without ever signing a document can have a binding contract based on their course of dealing. Open terms like price or delivery date do not automatically defeat the contract, as long as there is a reasonably certain basis for granting a remedy if something breaks down.
The $500 Statute of Frauds
The main exception to that flexibility is the Statute of Frauds. Any sale of goods priced at $500 or more needs some form of written evidence to be enforceable. The writing need not be a polished contract. It must indicate a deal was made, specify a quantity, and be signed by the party you are trying to hold to it. Without that writing, you generally cannot enforce the agreement in court, however strong your other evidence. Deals under $500 can be enforced on oral testimony or informal communications.1Legal Information Institute. UCC 2-201 – Formal Requirements; Statute of Frauds
Between merchants there is a shortcut. If one merchant sends a written confirmation of an oral deal and the recipient has reason to know what it says, the recipient has ten days to object in writing. Silence lets the confirmation satisfy the Statute of Frauds against both sides, even though the recipient never signed anything.1Legal Information Institute. UCC 2-201 – Formal Requirements; Statute of Frauds
A writing does not have to be on paper. Under the federal E-SIGN Act, a contract or signature cannot be denied legal effect just because it is electronic. An email chain, a digitally signed purchase order, or a click-through confirmation can satisfy the writing requirement so long as the record is accurate and accessible for later reference.2Office of the Law Revision Counsel. 15 USC 7001 – General Rule of Validity
Modifying a Sales Contract
One of the sharpest breaks from common law is modification. Common law requires new consideration from both sides to change a deal. Article 2 does not. An agreement to modify a sales contract needs no new consideration to bind the parties.3Legal Information Institute. UCC 2-209 – Modification, Rescission and Waiver If a supplier and buyer agree to adjust the price or shift the delivery schedule, that change stands on its own. The modification still has to be made in good faith, so one side cannot use economic pressure to extract a one-sided revision.
Extra Rules That Apply Only to Merchants
Article 2 separates casual sellers from professionals. A merchant is someone who regularly deals in the type of goods involved, or who otherwise holds themselves out as having expertise in those goods or in the trade practices around them. A furniture store selling a couch is a merchant. A homeowner selling a couch on a marketplace app is not. Several rules only bite when a merchant is on one or both sides of the deal.4Legal Information Institute. UCC 2-104 – Definitions: Merchant; Between Merchants; Financing Agency
Firm Offers
Under common law, an offer can be yanked back any time before acceptance unless the offeree paid for an option. Merchants are different. When a merchant makes a signed, written offer that promises to stay open, the offer is irrevocable for the stated period, or for a reasonable time if none is stated. The maximum irrevocable period is three months, and no separate payment is required to make it binding.5Legal Information Institute. UCC 2-205 – Firm Offers
The Battle of the Forms
Merchants rarely negotiate every line of a contract. They swap preprinted purchase orders and order confirmations that almost never line up. Common law’s “mirror image” rule would say any mismatch kills the deal. Article 2 is more realistic. A response that accepts the offer but includes different or additional terms still works as an acceptance, and between merchants the extra terms automatically become part of the contract unless they materially change the deal, the original offer expressly limits acceptance to its own terms, or the other side objects within a reasonable time.6Legal Information Institute. UCC 2-207 – Additional Terms in Acceptance or Confirmation
Warranties on the Goods
Article 2 builds in several layers of quality protection. Some come from what the seller actually says. Others attach by operation of law.
Express Warranties
Any statement of fact, promise, description, or sample a seller uses as part of the sale can create an express warranty. The seller does not need to use the word “warranty” or intend to make one. If a product listing says “waterproof to 30 meters” and the watch leaks at 10, that is a breach of an express warranty.7Legal Information Institute. UCC 2-313 – Express Warranties by Affirmation, Promise, Description, Sample The statement must have become part of the basis of the bargain, meaning the buyer relied on it or could reasonably have done so. Puffery like “best product on the market” generally does not count.
Implied Warranty of Merchantability
Whenever a merchant sells goods of the kind they regularly deal in, a warranty of merchantability attaches automatically. The product must be fit for the ordinary purposes that type of product serves. A space heater has to produce heat. Shoes have to hold together under normal walking. The standard is not perfection; it is that the goods would pass without objection in the trade and are of at least average quality for that type of product.8Legal Information Institute. UCC 2-314 – Implied Warranty: Merchantability; Usage of Trade
Implied Warranty of Fitness for a Particular Purpose
A different implied warranty kicks in when a seller knows the buyer needs a product for a specific, non-standard use and the buyer relies on the seller’s judgment to pick the right item. A customer tells a paint store owner they need a coating for a boat hull, the owner recommends an interior wall paint, and the paint fails on the hull. That is a breach of this warranty. Unlike merchantability, this one can apply to any seller, not just merchants.9Legal Information Institute. UCC 2-315 – Implied Warranty: Fitness for Particular Purpose
Disclaimers
Sellers can disclaim implied warranties, but Article 2 makes them follow specific steps. To disclaim merchantability, the disclaimer must actually use the word “merchantability,” and if it is in writing, it must be conspicuous, meaning bold, capitalized, or otherwise set off so a buyer cannot miss it. Sellers can also disclaim all implied warranties with phrases like “as is” or “with all faults.” If the buyer had a chance to inspect the goods before the sale and either examined them or refused to, no implied warranty covers defects a reasonable inspection would have revealed.10Legal Information Institute. UCC 2-316 – Exclusion or Modification of Warranties
Delivery, Inspection, and the Perfect Tender Rule
Once a contract exists, both sides have to perform. Article 2 generally gives buyers the right to insist on exactly what was promised.
If goods fail to conform to the contract in any way, the buyer can reject the entire shipment, accept all of it, or accept some commercial units and reject the rest. This is the perfect tender rule, and it is strict. A shipment of 1,000 bolts where five are the wrong size technically entitles the buyer to send everything back.11Legal Information Institute. UCC 2-601 – Buyer’s Rights on Improper Delivery Most commercial buyers do not reject over trivial defects, but the right itself is leverage.
After delivery, the buyer gets a reasonable chance to inspect before deciding. If a defect surfaces and the buyer rejects, the seller has a right to cure if the original delivery deadline has not passed, by notifying the buyer and delivering conforming goods within the contract timeframe.12Legal Information Institute. UCC 2-508 – Cure by Seller of Improper Tender or Delivery; Replacement Once the buyer accepts, they owe the price and lose the right to reject based on defects they knew about at the time.
Acceptance is not always final. A buyer can revoke acceptance of goods whose defects substantially impair their value, but only in narrow situations: the buyer accepted on the reasonable assumption the defect would be fixed and it was not, or the buyer accepted without discovering the defect because it was hard to detect or the seller gave assurances that masked it. Revocation has to happen within a reasonable time after discovery and requires notice to the seller.13Legal Information Institute. UCC 2-608 – Revocation of Acceptance in Whole or in Part The bar is deliberately higher than for initial rejection.
The perfect tender rule does not apply to installment contracts, where goods come in separate batches. A buyer can reject a single installment only if its defect substantially impairs the value of that installment and cannot be cured. The buyer can cancel the whole contract only when a defect in one or more installments substantially impairs the value of the whole deal.14Legal Information Institute. UCC 2-612 – Installment Contract; Breach
Sometimes events outside the seller’s control make performance unrealistic. A seller is excused from delivering on time, or at all, when an unforeseen event makes performance impracticable and the non-occurrence of that event was a basic assumption of the contract. Natural disasters, government embargoes, and sudden regulatory changes are typical examples. The seller must notify the buyer promptly. If the disruption only partially affects capacity, the seller must allocate available production fairly among customers.15Legal Information Institute. UCC 2-615 – Excuse by Failure of Presupposed Conditions
Who Bears Risk of Loss in Transit
Between the moment a seller ships and the moment a buyer receives, things can go wrong. A truck crashes. A warehouse burns. Article 2 decides who swallows the loss based on the type of contract and whether either side has breached.
In a shipment contract, risk passes to the buyer once the seller delivers the goods to the carrier. The buyer carries the risk during transit even though they have never touched the goods. In a destination contract, the seller carries transit risk because the deal requires delivery to a specific place; risk does not shift until the goods arrive and the buyer can take delivery.16Legal Information Institute. UCC 2-509 – Risk of Loss in the Absence of Breach Most commercial contracts are treated as shipment contracts unless the language specifically requires delivery at a destination, which is why shipping terms deserve close attention.
Breach shifts the calculus. When a seller ships defective goods the buyer has a right to reject, the seller keeps the risk until the goods are either cured or accepted. When a buyer repudiates before risk has passed, the seller can treat the risk as resting on the buyer for a commercially reasonable time, at least to the extent the seller’s own insurance does not cover the loss.17Legal Information Institute. UCC 2-510 – Effect of Breach on Risk of Loss
Remedies When the Deal Falls Apart
Both buyers and sellers get a set of remedies when the other side breaches. The aim is to put the injured party where they would have been if the contract had been performed, not to punish the breacher.
What a Buyer Can Recover
If a seller fails to deliver or ships defective goods, the buyer’s most practical move is often to “cover” by buying substitute goods elsewhere. The buyer can then recover the difference between the cover price and the contract price, plus incidental and consequential damages, minus any expenses saved because of the breach.18Legal Information Institute. UCC 2-712 – Cover; Buyer’s Procurement of Substitute Goods The cover purchase has to be made in good faith, without unreasonable delay, and at a reasonable price. A buyer who does not cover is not punished and can still pursue other damage formulas.
When the buyer has already accepted defective goods, the measure shifts. The buyer recovers the difference between the value of the goods as accepted and the value they would have had if they had matched the warranty.19Legal Information Institute. UCC 2-714 – Buyer’s Damages for Breach in Regard to Accepted Goods Incidental damages (inspection costs, return shipping, the cost of arranging cover) and consequential damages (lost profits and other losses the seller had reason to foresee) can be added on top.20Legal Information Institute. UCC 2-715 – Buyer’s Incidental and Consequential Damages
What a Seller Can Recover
If a buyer wrongfully rejects goods or walks away from the deal, the seller can resell the goods in a commercially reasonable manner and recover the difference between the resale price and the contract price, plus incidental damages, minus expenses saved.21Legal Information Institute. UCC 2-706 – Seller’s Resale Including Contract for Resale If the goods cannot readily be resold, or the buyer has accepted them and simply refuses to pay, the seller may be able to sue for the full contract price.
Liquidated Damages and Unconscionable Terms
Parties can agree in advance to a set damage figure for a breach, but the number has to be reasonable in light of the anticipated or actual harm. A liquidated damages clause that sets an unreasonably high amount is void as a penalty.22Legal Information Institute. UCC 2-718 – Liquidation or Limitation of Damages; Deposits
Beyond that, a court can refuse to enforce any contract or clause it finds unconscionable, meaning it was so one-sided at the time of formation that enforcing it would be fundamentally unfair. The court can void the whole contract, strike the offending clause, or limit its application to produce a fair result.23Legal Information Institute. UCC 2-302 – Unconscionable Contract or Clause This is the safety valve for deals where one side had no real bargaining power.
How Long You Have to Sue
A lawsuit for breach of a sales contract has to be filed within four years of the breach. The clock starts when the breach actually happens, not when you discover it, which catches some buyers off guard. Defective goods delivered on January 1 start the four-year clock that day, even if the problem does not surface until much later.24Legal Information Institute. UCC 2-725 – Statute of Limitations in Contracts for Sale
There is one exception. When a warranty explicitly extends to future performance and the defect can only be discovered later, the clock starts when the buyer discovers or should have discovered the breach. Parties can agree in the contract to shorten the limitations period, but never below one year, and they cannot push it past four.24Legal Information Institute.
