When the dispute is over the sale of goods — inventory, equipment, raw materials, or any movable product — Missouri does not apply ordinary common-law contract rules. It applies Article 2 of the Uniform Commercial Code, adopted in Missouri at Chapter 400 of the Revised Statutes, with its own rules for how a deal is formed, what warranties come built in, when a buyer can reject goods, what damages are recoverable, and how long you have to sue — rules that often produce a different result than a common-law claim would.
This guide explains when Article 2 applies, how its formation and statute-of-frauds rules differ from the common law, the warranties the Code reads into a sale, the remedies for breach, and the four-year statute of limitations for sales of goods. Knowing whether your dispute is an Article 2 case often controls both the deadline and the recovery.
When does UCC Article 2 apply in Missouri?
Article 2 governs transactions in goods. "Goods" means things that are movable when identified to the contract — equipment, supplies, vehicles, crops, and manufactured products. It does not govern services (consulting, repair, professional work, or labor alone) or real estate, which stay under common-law contract and property rules. The dividing line matters because the Code's formation, warranty, and remedy rules — and its four-year limitations period — apply only when Article 2 governs.
The "predominant purpose" test for mixed deals
Many contracts mix goods and services — a contractor who supplies and installs an HVAC system, or a vendor who sells software and provides setup. Missouri resolves these "hybrid" contracts with the predominant purpose test: is the contract's primary thrust the sale of goods (services incidental) or the rendering of services (goods incidental)? If goods predominate, Article 2 governs the entire contract, including the labor; if services predominate, common-law rules apply. Because the answer can flip the limitations period from four years to five or ten, characterization is often the first battle.
How does Article 2 change the rules of contract formation?
Article 2 is far more forgiving than the common law about forming a contract, supplying missing pieces rather than letting a deal collapse for indefiniteness.
- Open terms and gap-fillers. A sales contract can be enforceable even with terms left open, so long as the parties intended to contract and there is a reasonably certain basis for a remedy. The Code fills gaps with a reasonable price, delivery at the seller's place of business, and payment on delivery. Quantity, however, generally must be stated; it is the one term the Code will not invent.
- The "battle of the forms." Under the common-law "mirror image" rule, an acceptance that adds terms is a counteroffer. Article 2 (RSMo § 400.2-207) rejects that: a definite acceptance can form a contract even if it states additional terms. Between merchants, those terms become part of the contract unless they materially alter it, the offer limited acceptance to its terms, or the other side objects — which is why two businesses trading purchase orders and acknowledgments with conflicting fine print can still be bound.
- Merchant rules. Article 2 holds merchants — those who deal in goods of the kind or hold themselves out as having special knowledge — to higher standards on the statute of frauds, the battle of the forms, and merchantability.
The UCC statute of frauds for goods of $500 or more
A contract for the sale of goods for $500 or more generally must be evidenced by a writing signed by the party to be charged (RSMo § 400.2-201) — the Code's own statute of frauds. But Article 2 softens it: a merchant confirmation the recipient does not timely object to binds the recipient even unsigned; part performance (goods received and accepted, or paid for) takes the contract out to that extent; specially manufactured goods may be enforceable without a writing; and a party who admits a contract was made cannot hide behind the statute. The writing need not contain every term but is not enforceable beyond the quantity shown.
What warranties does Missouri law read into a sale of goods?
Warranties are where Article 2 disputes are often won or lost, because the Code attaches promises about the goods automatically unless properly disclaimed.
- Express warranty. Any affirmation of fact, promise, description, or sample that becomes part of the basis of the bargain warrants that the goods will conform. Mere "puffing" does not.
- Implied warranty of merchantability (RSMo § 400.2-314). When the seller is a merchant in goods of that kind, the law implies the goods are merchantable — fit for the ordinary purposes such goods are used for, adequately packaged, and conforming to label promises. This is the workhorse warranty in most disputes.
- Implied warranty of fitness for a particular purpose (RSMo § 400.2-315). Where the seller has reason to know the particular purpose the buyer needs the goods for and that the buyer is relying on the seller's skill to select them, the law implies they will fit that purpose.
Disclaimers and "as is" sales
Sellers can limit or eliminate implied warranties, but only by following the Code's rules. To disclaim merchantability, the language must mention "merchantability" and, if written, generally be conspicuous; disclaiming fitness requires a conspicuous writing. Selling goods "as is" generally disclaims implied warranties, and a buyer's examination can cut off warranties for defects the inspection should have revealed. A disclaimer that is buried or omits the required words may be ineffective, so these fights turn on the document's exact wording.
What are the remedies when a sale of goods goes wrong?
Article 2 gives buyers and sellers a tailored remedy toolkit:
- The perfect-tender rule. Unlike the common law's "substantial performance," Article 2 generally entitles a buyer to goods that conform exactly — if the goods or tender fail in any respect, the buyer may reject the whole, accept the whole, or accept some commercial units and reject the rest, subject to the seller's right to cure within the contract time.
- Rejection and revocation. A buyer must reject non-conforming goods within a reasonable time and notify the seller. Even after accepting, a buyer can revoke acceptance of goods whose non-conformity substantially impairs their value, where acceptance occurred without discovery of the defect or on the assumption it would be cured.
- Cover. A buyer may "cover" by buying substitute goods in good faith and recover the cover-to-contract difference plus incidental and consequential damages, or instead the market-to-contract gap.
- Incidental and consequential damages. Incidental damages cover costs like inspection, transport, and storage; consequential damages cover foreseeable losses the seller had reason to know about, including lost profits, subject to the duty to mitigate. Contracts often limit or exclude consequential damages, and the Code generally enforces such limits.
A seller facing breach may resell and recover the resale-to-contract difference, recover the market-to-contract difference, recover the price of goods accepted or unsellable, and stop delivery in transit. Where money is inadequate — as with unique goods — a buyer may seek specific performance or replevin.
How long do you have to sue under Article 2?
A claim for breach of a contract for sale of goods must be brought within four years after the cause of action accrues (RSMo § 400.2-725) — shorter than Missouri's ten-year period for a written promise to pay money and its five-year catch-all for other contracts.
The cause of action generally accrues when the breach occurs, whether or not the buyer knew of it. For breach of warranty, the breach usually occurs on delivery — not when the defect is later discovered — unless the warranty explicitly extends to future performance, in which case the clock runs from discovery. The parties may by their original agreement shorten the period to as little as one year but may not extend it. A warranty claim can therefore expire four years after delivery even if the defect surfaces later.
Frequently Asked Questions
Does the UCC apply to my contract, or does ordinary contract law?
UCC Article 2 (RSMo Chapter 400) applies to transactions in goods — movable products like equipment, inventory, and materials — not services or real estate. For mixed deals, Missouri uses the predominant purpose test: if the deal is mainly about goods, Article 2 governs the whole contract; if mainly services, common-law rules apply.
What is the difference between Article 2 and a common-law contract claim?
Article 2 fills open terms, resolves the "battle of the forms," reads in implied warranties, and gives buyers rejection, revocation, and cover remedies under a strict "perfect tender" standard, with a four-year limit. Common-law contracts use the mirror-image rule, "substantial performance," no implied warranties, and five- or ten-year periods.
Does a contract for goods have to be in writing?
A contract for the sale of goods for $500 or more generally must be in a signed writing under the UCC statute of frauds (RSMo § 400.2-201). But exceptions apply — a merchant's unobjected-to confirmation, goods received and accepted or paid for, specially manufactured goods, and a court admission can each satisfy or excuse it.
What is the implied warranty of merchantability?
Under RSMo § 400.2-314, when the seller is a merchant in goods of that kind, the law implies the goods are merchantable — fit for ordinary purposes, properly packaged and labeled, and of fair average quality. It applies even if the contract is silent on quality, unless disclaimed.
Can a seller sell goods "as is" and avoid warranties?
Often, yes. Selling goods "as is" with conspicuous language generally disclaims the implied warranties. A merchantability disclaimer normally must mention "merchantability," and a fitness disclaimer must be a conspicuous writing — so the exact language controls.
Legal Disclaimer
This guide provides general legal information about Missouri law and is not legal advice. It does not create an attorney-client relationship. Whether Article 2 applies, what warranties attach, and what remedies and deadlines control depend on your specific goods, contract, and facts; consult a qualified Missouri attorney promptly, because sale-of-goods claims carry a strict four-year statute of limitations.
