UBE UCC Article 2 (sales)

Last updated: May 2, 2026

UCC Article 2 (sales) questions are one of the highest-leverage areas to study for the UBE. This guide breaks down the rule, the elements you need to recognize, the named traps that catch most students, and a memory aid that scales to test day. Read it once, then practice the same sub-topic adaptively in the app.

The rule

UCC Article 2 governs contracts for the sale of goods (movable, tangible personal property) under UCC §2-102 and §2-105. Article 2 displaces common-law rules on mirror-image acceptance, the pre-existing duty rule, and the parol evidence rule for goods contracts; it imposes a $500-or-more Statute of Frauds (UCC §2-201), good-faith and merchant standards (UCC §1-304, §2-104), and gap-fillers for missing terms (price, place, time, payment under §§2-305 to 2-310). When the contract mixes goods and services, courts apply the predominant-purpose test to decide whether Article 2 or the common law governs the entire deal.

Elements breakdown

Scope: Sale of Goods

Article 2 applies when the contract is for the sale of goods, defined as things movable at the time of identification to the contract.

  • Contract is for a sale (transfer of title for price)
  • Subject matter is goods
  • Goods are movable when identified
  • Not real estate, services, or intangibles

Common examples:

  • Sale of a car, sale of lumber, sale of harvested crops
  • Future goods (to be manufactured) once identified
  • Specially manufactured goods that fit §2-201(3)(a)

Predominant-Purpose Test (Mixed Contracts)

For hybrid goods/services contracts, the court asks whether the contract's predominant thrust is the rendition of services with goods incidentally involved, or the sale of goods with services incidentally involved.

  • Identify the language and structure of the contract
  • Identify the nature of the supplier's business
  • Compare the relative cost of goods vs. services
  • Determine the dominant purpose of the transaction

Common examples:

  • Installation of a custom HVAC system — usually goods (UCC)
  • Surgery using a prosthetic — usually services (common law)
  • Software customization — split authority

Merchant Status (UCC §2-104)

A merchant is a person who deals in goods of the kind, or who otherwise by occupation holds himself out as having knowledge or skill peculiar to the practices or goods involved.

  • Deals in goods of the kind sold OR
  • Holds self out by occupation as having skill
  • OR employs an agent who has such skill
  • Status triggers heightened duties throughout Article 2

Common examples:

  • A car dealer is a merchant in cars
  • A homeowner selling a used couch is not a merchant
  • A farmer selling crops — split authority but most courts say merchant

Statute of Frauds (UCC §2-201)

A contract for the sale of goods of $500 or more is unenforceable absent a writing signed by the party to be charged that indicates a contract was made and specifies a quantity.

  • Goods of $500 or more
  • Writing signed by party to be charged
  • Indicates a contract for sale was made
  • Specifies quantity (the only essential term)

Common examples:

  • Merchant's confirmatory memo exception — §2-201(2)
  • Specially manufactured goods exception — §2-201(3)(a)
  • Admission in pleadings or court — §2-201(3)(b)
  • Part performance (payment accepted or goods received) — §2-201(3)(c)

Offer and Acceptance — Battle of the Forms (UCC §2-207)

A definite expression of acceptance operates as acceptance even if it states terms additional to or different from those offered, unless acceptance is expressly conditional on assent to the new terms.

  • Definite and seasonable expression of acceptance
  • Not expressly conditional on new-term assent
  • Between merchants, additional terms become part of the contract unless: (i) offer expressly limits acceptance; (ii) terms materially alter; or (iii) timely objection
  • Conduct alone may form a contract; knockout rule applies to differing terms in many jurisdictions

Firm Offer (UCC §2-205)

A merchant's signed written offer to buy or sell goods that gives assurance it will be held open is irrevocable for the time stated, or if no time is stated, for a reasonable time, but in no event more than three months — without consideration.

  • Offeror is a merchant
  • Offer is in a signed writing
  • Writing gives assurance the offer will be held open
  • No consideration required
  • Maximum irrevocable period: 3 months

Modification (UCC §2-209)

An agreement modifying a contract within Article 2 needs no consideration to be binding, but must be made in good faith.

  • Original contract within Article 2
  • Modification made in good faith
  • No new consideration required
  • SoF applies if modified contract is $500+
  • No-oral-modification clause enforceable

Implied Warranties

Article 2 imposes implied warranties absent a valid disclaimer.

  • Implied warranty of merchantability (§2-314): seller is a merchant in goods of the kind; goods fit ordinary purposes
  • Implied warranty of fitness for particular purpose (§2-315): seller knows buyer's particular purpose; buyer relies on seller's skill
  • Disclaimer of merchantability must mention 'merchantability' and if written be conspicuous
  • Disclaimer of fitness must be in writing and conspicuous; 'as is' disclaims both

Risk of Loss (UCC §2-509, §2-510)

Risk of loss allocates which party bears the loss when conforming goods are destroyed without fault before the buyer accepts.

  • Shipment contract (FOB seller's place): risk passes when seller delivers to carrier
  • Destination contract (FOB buyer's place): risk passes on tender at destination
  • Non-carrier merchant seller: risk passes on buyer's receipt
  • Non-carrier non-merchant seller: risk passes on tender
  • Breach by seller: risk stays with seller until cure or acceptance

Perfect Tender Rule (UCC §2-601)

In a single-delivery contract, if the goods or tender of delivery fail in any respect to conform, the buyer may reject the whole, accept the whole, or accept any commercial units and reject the rest.

  • Single-delivery contract (not installment)
  • Goods or tender fail in any respect to conform
  • Buyer rejects within a reasonable time
  • Buyer seasonably notifies seller
  • Seller may cure within contract time or with reasonable additional time if seller had reasonable grounds to believe tender would be acceptable

Common patterns and traps

The Goods-vs-Services Misclassification

The most common Article 2 trap. The fact pattern describes a transaction with both goods and services components — a contractor installing materials, a doctor implanting a device, a software vendor customizing code. The wrong answers apply common-law doctrine (mirror image, pre-existing duty, full essential terms) when the predominant purpose is goods, or apply UCC rules to a service contract dressed up with incidental products.

An answer choice that says 'No, because the acceptance contained additional terms and therefore operated as a counter-offer' — correct under common law, wrong under §2-207 between merchants.

The Merchant-Status Skip

Several Article 2 rules apply only between merchants or only when the seller is a merchant: the §2-207(2) gap-filler for additional terms, the §2-201(2) confirmatory memo, the §2-205 firm offer, and the §2-314 merchantability warranty. The trap distractor either skips the merchant inquiry entirely or assumes merchant status without facts to support it (e.g., a one-time household sale).

An answer that says 'The implied warranty of merchantability is breached because the goods were defective' — wrong if the seller is not a merchant in goods of the kind.

The Mirror-Image Mirage

Common-law trained candidates default to mirror-image acceptance. Under §2-207, a definite expression of acceptance forms a contract even with new terms, unless acceptance is expressly conditional on assent. The trap is treating an acknowledgment with additional terms as a counter-offer instead of running the §2-207 framework.

An answer that says 'The buyer's purchase order and the seller's acknowledgment do not match, so no contract was formed' — wrong unless the acknowledgment was expressly conditional.

The Perfect-Tender Overreach

Article 2's perfect tender rule lets buyers reject for any nonconformity in single-delivery contracts — but it does not apply to installment contracts (substantial impairment under §2-612), and the seller's right to cure under §2-508 often saves the deal. The trap distractor either applies perfect tender to installment contracts or ignores the seller's cure right when the time for performance has not expired.

An answer that says 'The buyer may reject the entire installment contract because the first shipment was nonconforming' — wrong; installment contracts use the substantial impairment test.

The Risk-of-Loss Reflex

Risk of loss turns on shipment vs. destination contract and merchant vs. non-merchant seller, not on who has 'title.' The trap distractor invokes title or possession to allocate loss instead of running §§2-509 and 2-510. A breaching seller keeps risk regardless of the default rule.

An answer that says 'The buyer bore the risk because title had passed when the goods were identified' — wrong; risk under Article 2 is independent of title.

How it works

When a question gives you a transaction, your first move is always the goods/services cut. Suppose Reyes Restaurant Group orders 200 custom-engraved bar stools from Liu Furniture Co. for $18,000, with installation included for $400. The predominant purpose is the sale of goods (the stools), so Article 2 governs the entire deal. Now you apply UCC rules: the $500 SoF is satisfied if there's a signed writing with quantity; if Reyes and Liu are both merchants, a confirmatory memo from one binds the other absent objection within ten days. If Liu's acknowledgment form adds an arbitration clause, §2-207 controls — between merchants, the term enters the contract unless it materially alters (arbitration usually does, splitting authority). Watch for substitution traps: under common law, additional terms in an acceptance would be a counter-offer; under Article 2 with merchants, they may slide into the contract automatically.

Worked examples

Worked Example 1

Is the arbitration clause part of the contract?

  • A Yes, because Reyes's acknowledgment operated as a counter-offer that Patel accepted by taking delivery of the beans.
  • B Yes, because under UCC §2-207, additional terms between merchants become part of the contract unless they materially alter it, and arbitration clauses are routine.
  • C No, because under UCC §2-207, an arbitration clause is generally treated as a material alteration that does not enter the contract absent express assent. ✓ Correct
  • D No, because Patel's silence cannot constitute acceptance of additional terms under the common-law mirror-image rule.

Why C is correct: This is a goods contract between merchants, so UCC §2-207 governs. Reyes's acknowledgment is a definite expression of acceptance that formed a contract on the offer's terms. The added arbitration clause is an additional term; between merchants it would enter the contract unless it materially alters it. Most courts treat arbitration clauses as material alterations because they deprive a party of a judicial forum and substantive procedural rights, so the clause does not become part of the contract.

Why each wrong choice fails:

  • A: This applies the common-law mirror-image rule, which §2-207 displaces for goods contracts. A definite expression of acceptance forms a contract under Article 2 even with additional terms, unless acceptance is expressly conditional on assent. (The Mirror-Image Mirage)
  • B: The first half of the rule statement is correct, but the conclusion that arbitration clauses are 'routine' is wrong — courts overwhelmingly treat arbitration clauses as material alterations under §2-207(2)(b) because they significantly affect remedies.
  • D: This applies common-law doctrine to a goods contract. The mirror-image rule does not govern; §2-207 does. The reasoning also conflates silence-as-acceptance (a separate doctrine) with the §2-207 framework for additional terms. (The Mirror-Image Mirage)
Worked Example 2

Is the oral modification enforceable against Hovan?

  • A Yes, because UCC §2-209 allows good-faith modifications without new consideration.
  • B Yes, because the pre-existing duty rule does not apply to construction contracts under the Restatement (Second) of Contracts.
  • C No, because the predominant purpose of the contract was services, so the common-law pre-existing duty rule requires new consideration. ✓ Correct
  • D No, because any modification of a contract worth more than $500 must be in writing under the Statute of Frauds.

Why C is correct: Apply the predominant-purpose test first. Although materials cost $42,000, the contract is primarily for construction services — design, labor, and installation — with materials incidental to the build. The common law therefore governs, and under the pre-existing duty rule a modification needs new consideration to be binding. Hovan promised only to do more (upgrade the grill) without receiving anything new in return, so the oral modification is unenforceable absent consideration.

Why each wrong choice fails:

  • A: §2-209 only applies if Article 2 governs, which requires a goods contract. Here the predominant purpose is construction services, so the common law and its pre-existing duty rule control. (The Goods-vs-Services Misclassification)
  • B: The Restatement (Second) §89 allows modification without consideration only if circumstances were unanticipated and the modification is fair and equitable — not as a general rule. The pre-existing duty rule is alive and well at common law.
  • D: The $500 SoF is a UCC rule (§2-201) and applies only to goods contracts. This is a services-predominant contract, so the UCC SoF does not govern modifications. (The Goods-vs-Services Misclassification)
Worked Example 3

Is Hovagimian bound to sell the press at $85,000?

  • A Yes, because Hovagimian's signed written promise to keep the offer open was a firm offer under UCC §2-205, irrevocable for the time stated. ✓ Correct
  • B Yes, but only because Reyes accepted before July 1; Hovagimian's revocation was effective for offers accepted after May 15.
  • C No, because no consideration was paid to keep the offer open, so it remained revocable like any common-law option contract.
  • D No, because UCC §2-205 caps the irrevocable period at three months, and the May 15 revocation was effective after that period expired.

Why A is correct: Hovagimian is a merchant in industrial machinery, the offer was in a signed writing, and it gave assurance it would be held open until July 1 — all elements of a firm offer under UCC §2-205. Firm offers require no consideration. The offer is irrevocable for the time stated (here, until July 1) but capped at three months from April 1, which is July 1. Because Reyes accepted on June 10, within both the stated period and the three-month cap, Hovagimian is bound.

Why each wrong choice fails:

  • B: This is the right outcome with garbled reasoning. Hovagimian's revocation was ineffective at all times during the firm-offer period, not just before May 15. The firm offer makes revocation a nullity until the irrevocable period expires.
  • C: This applies the common-law option-contract rule, which requires consideration. UCC §2-205 dispenses with consideration entirely for merchant firm offers — that is the whole point of the rule. (The Merchant-Status Skip)
  • D: The three-month cap is measured from the offer date (April 1), making July 1 the maximum. The stated period (until July 1) is exactly the cap, so the offer was irrevocable through July 1. Reyes accepted June 10, well within that window.

Memory aid

MQTS for the SoF: Merchant exception, Quantity (only essential term), Three exceptions (specially-manufactured, admissions, part performance), Signed writing. For Article 2 vs. common law, ask: 'Are these goods?' If yes, default to UCC; then test merchant status because half the UCC's quirks (firm offer, §2-207 between merchants, §2-314, confirmatory memo) require it.

Key distinction

The bar-defining cut is goods vs. services (and within mixed contracts, the predominant-purpose test). If you misclassify, every downstream rule you apply is wrong: mirror-image vs. §2-207, $500 SoF vs. one-year SoF, perfect tender vs. material breach, gap-fillers vs. essential-terms-must-be-definite. Always state the cut explicitly on an MEE.

Summary

Article 2 governs sales of goods and replaces common-law contract rules with merchant-friendly defaults — flexible formation under §2-207, the firm offer under §2-205, no-consideration modification under §2-209, implied warranties of merchantability and fitness, gap-fillers for missing terms, and the perfect tender rule for single-delivery contracts.
