Consequential damages under UCC Article 2 are the downstream financial harms a buyer suffers when a seller breaches — lost profits, shutdowns, liability to customers, and physical injury to people or property. They sit on top of the buyer’s basic damages for the defective or missing goods themselves. Section 2-715(2) authorizes two categories: economic losses the seller had reason to anticipate at the time of contracting, and injury to person or property proximately caused by a breach of warranty. Recovering them is harder than it sounds, and most commercial contracts try to shut the door on them entirely.
What Section 2-715(2) Actually Covers
Section 2-715(2) splits consequential damages into two subsections that operate on very different rules.
Subsection (a) covers economic losses: lost profits from a dark production line, revenue you couldn’t earn because you couldn’t fulfill your own contracts, penalties your customers charged you for late delivery. These losses are recoverable only if the seller had reason to know of the buyer’s “general or particular requirements and needs” at the time of contracting, and only to the extent the buyer couldn’t reasonably prevent the loss by cover or otherwise.
Subsection (b) covers physical harm: injury to a person or damage to property proximately resulting from any breach of warranty. The foreseeability test that governs economic losses does not apply here.
Consequential damages are not a standalone remedy. They stack on top of the buyer’s direct-damage recovery — the cover/contract-price gap under Section 2-712, the market/contract-price gap under Section 2-713, or the value difference for accepted but defective goods under Section 2-714. The direct damages cover the loss on the goods. The consequential damages cover what the breach cost your business beyond the transaction itself.
Incidental Damages Are Not the Same Thing
Section 2-715(1) incidental damages are the immediate out-of-pocket costs of handling the breach: inspection, transportation, storage of rejected goods, and the expenses of locating substitute goods. If you paid rush shipping to get a replacement part, that is incidental.
If your plant still lost three days of output despite the rush shipping, that lost production is consequential. The distinction matters because incidental damages are easy to document with invoices and face no foreseeability test, while consequential damages carry heavier proof burdens and heavier scrutiny. Classify your losses correctly before you plead them.
Proving an Economic Loss Claim
The Seller Had Reason to Know
This is where most claims collapse. The seller doesn’t need actual knowledge of your exact exposure, but a reasonable person in the seller’s position must have been able to foresee the kind of loss you’re claiming. A seller of industrial compressors to a manufacturing plant should foresee that a defective compressor could shut down production. That same seller has a much weaker reason to know about the unusually profitable contract you had riding on that specific production run if you never mentioned it.
The implied warranty of fitness for a particular purpose under Section 2-315 helps here. When the seller knew your specific purpose and you relied on the seller’s expertise to pick the product, the “reason to know” element is largely built in. If the goods fail that purpose, the downstream losses are nearly inherent in the deal.
You Couldn’t Reasonably Prevent the Loss
Section 2-715(2)(a) bars recovery for losses the buyer could have reasonably prevented by cover or otherwise. Cover under Section 2-712 means buying substitute goods in good faith and without unreasonable delay. Section 2-712(3) says failing to cover doesn’t bar other remedies, but in practice a court won’t award lost profits for downtime you could have avoided by sourcing a replacement.
Keep the categories straight: the cost of arranging cover (broker fees, expedited freight) is incidental under Section 2-715(1). The business losses you still suffer after a reasonable cover effort are consequential.
You Can Prove the Loss With Reasonable Certainty
Lost profits must be proven with reasonable certainty, not mathematical precision, but not speculation either. Historical financials, tax returns, signed purchase orders from your own customers, and industry benchmarks are the usual evidence. A business claiming $200,000 in lost profits needs to show what its margins actually looked like before the breach and tie the decline to the seller’s failure. Before-and-after comparisons, benchmarking against similar unaffected businesses, and lost-market-share calculations are all common approaches. Expert testimony from an economist or forensic accountant often helps; a business owner with firsthand knowledge of the company’s books can sometimes carry the proof alone.
New businesses without a track record face a steeper climb. Projections built on business plans, market data, and comparable operators are possible but viewed skeptically.
Personal Injury and Property Damage Follow Different Rules
Section 2-715(2)(b) is simpler and more buyer-friendly. If a breach of warranty proximately causes physical injury to a person or damage to property, those losses are recoverable with no “reason to know” showing. A defective heater that burns down a warehouse produces recoverable property damage whether or not the seller anticipated that specific risk. A consumer hurt by a defective product can recover medical bills and lost wages under this subsection.
Who can bring the claim depends on your state. Section 2-318 gives states three alternative versions extending warranty protection beyond the direct buyer — the narrowest reaching only household members and guests, the broadest reaching any person reasonably expected to use or be affected by the goods. Which alternative your state adopted controls whether, say, an employee injured by a piece of equipment the employer bought can recover consequential damages for personal injury.
Contract Waivers and When They Hold
Section 2-719(3) lets parties limit or exclude consequential damages, and in business-to-business contracts courts routinely enforce those clauses. Two sophisticated companies allocating risk between themselves is treated as a reasonable bargain. The statute itself says limiting commercial consequential damages is not unconscionable. If you signed a waiver with open eyes, expect to be bound by it.
Consumer goods and personal injury are different. Section 2-719(3) treats any limitation on consequential damages for personal injury in the case of consumer goods as presumptively unconscionable, and the seller bears a burden that is nearly impossible to meet.
Many contracts pair a consequential damages waiver with a limited remedy — typically repair or replacement of defective goods. Section 2-719(2) says that when the exclusive remedy “fail[s] of its essential purpose,” the buyer can pursue any remedy the UCC provides. The classic case: a seller tries repeatedly to repair a defective machine and never fixes it. At that point the limited remedy has collapsed. Whether the consequential damages waiver collapses with it is contested. Some courts treat the two clauses as linked; others enforce the waiver independently even after the limited remedy fails. The drafting of the contract and the jurisdiction’s case law both matter.
Give Notice, and Watch the Clock
Section 2-607(3)(a) requires a buyer who has accepted goods to notify the seller of any breach within a reasonable time after discovering it or after the buyer should have discovered it. Fail to give timely notice and you are “barred from any remedy” — direct damages, consequential damages, and a refund all go away together. The notice doesn’t need to be a formal legal filing. A letter or email identifying the defect and stating that the goods don’t conform is enough. Send it as soon as you find the problem.
Section 2-725 then gives you four years to file suit, running from the breach itself rather than from discovery. A latent defect present at delivery but not detected for three years leaves you only one year to sue. The parties can shorten this period in the original contract to as little as one year, though they cannot extend it beyond four. Shortened limitation periods are common in commercial contracts and generally enforceable, so read your agreement before assuming you have the full four years.
Sellers Don’t Get Consequential Damages
One feature of Article 2 that surprises people: consequential damages are a one-way street. Section 2-715 authorizes them only for buyers. When a buyer breaches by refusing to accept goods or failing to pay, the seller’s remedies under Sections 2-706 through 2-710 are confined to resale damages, market-price damages, and incidental damages — storage, transportation, and the expenses of stopping delivery and arranging resale under Section 2-710.
A seller whose breach causes downstream harm (a damaged supplier relationship, lender penalties triggered by a revenue shortfall) has no statutory path to consequential damages under Article 2. Section 2-708(2) does let a seller recover lost profits in narrow situations where resale or market-price measures don’t make the seller whole, but that is a direct-damages measure for lost volume, not a Section 2-715 consequential recovery. Sellers who want protection against downstream losses have to negotiate for it in the contract.
