UCC 2-601: Buyer’s Rights on Improper Delivery

UCC 2-601 gives a buyer the right to reject goods when the goods or the delivery fail to conform to the contract in any respect. This is the “perfect tender rule.” Unless the contract says otherwise, the buyer can reject the whole shipment, accept the whole shipment, or accept any commercial units that conform and reject the rest.1Legal Information Institute. Uniform Commercial Code 2-601 – Buyer’s Rights on Improper Delivery

The language is deliberately broad. A shipment that arrives late, a product in the wrong color, or a delivery of 99 units when 100 were ordered are all nonconforming tenders. The rule does not ask whether the defect is serious or trivial. Any deviation triggers the buyer’s rights, which is a stricter standard than general contract law applies to service or construction agreements.

The Buyer’s Three Options

When a tender fails to conform, 2-601 gives you exactly three choices.1Legal Information Institute. Uniform Commercial Code 2-601 – Buyer’s Rights on Improper Delivery

  • Reject the whole shipment. You send everything back and can pursue damages or demand a conforming delivery. This fits when the defect runs through the order or when a partial delivery is useless to you.
  • Accept the whole shipment. You keep everything, pay the contract price, and still recover damages for the nonconformity — provided you notify the seller within a reasonable time. This path makes sense when the goods are still usable and replacing them costs more than living with the defect.2Legal Information Institute. Uniform Commercial Code 2-607 – Effect of Acceptance; Notice of Breach
  • Accept the conforming commercial units and reject the rest. You keep the good portions and send back the bad. This is the most surgical option, but it only works at commercial unit boundaries, not by pulling individual parts out of a machine or items out of a matched set.

What Counts as Nonconforming

Nonconformity covers every dimension of the bargain. Physical quality is the obvious one: items that fail to meet technical specifications, material grades, or the condition of samples shown during negotiation. Quantity counts too. A short shipment is nonconforming even if every unit delivered is flawless. Delivery terms matter as well. If the contract calls for refrigerated transport and the goods arrive in a standard truck, the tender is nonconforming regardless of whether the goods were damaged in transit.1Legal Information Institute. Uniform Commercial Code 2-601 – Buyer’s Rights on Improper Delivery

Commercial Units Set the Line for Partial Rejection

A commercial unit is whatever the market treats as a single whole for sale, where splitting it apart would destroy its character or value. A single machine, a suite of furniture, a gross of pencils, or a carload of grain can each be a commercial unit depending on how the trade views them.3Legal Information Institute. Uniform Commercial Code 2-105 – Definitions: Transferability; Goods; Future Goods; Lot; Commercial Unit

This definition controls partial rejection. Accepting any part of a commercial unit counts as accepting the entire unit.4Legal Information Institute. Uniform Commercial Code 2-606 – What Constitutes Acceptance of Goods A buyer who receives a nonconforming industrial engine cannot strip out the functional components and reject the housing. Before deciding to accept part of a mixed shipment, figure out what the trade considers one unit. That boundary determines what you can keep and what you can send back.

How to Reject Goods Properly

Rejection is not simply refusing a package at the door. The UCC imposes procedural requirements, and failing to follow them can convert a rightful rejection into a legal acceptance.

The rejection must happen within a reasonable time after delivery, and it is legally ineffective unless you notify the seller.5Legal Information Institute. Uniform Commercial Code 2-602 – Manner and Effect of Rightful Rejection A dated email or certified letter beats a phone call for proving timely notice. Silence or delay destroys rejection rights faster than almost anything else in commercial litigation.

After rejecting, a buyer who already has physical possession of the goods must hold them with reasonable care long enough for the seller to arrange pickup.5Legal Information Institute. Uniform Commercial Code 2-602 – Manner and Effect of Rightful Rejection You cannot use the goods in the meantime. Using rejected goods is one of the fastest ways for a court to find that you actually accepted them.

Extra Duties for Merchant Buyers

Merchant buyers face additional obligations. When the seller has no agent or place of business near where the goods were rejected, a merchant buyer must follow any reasonable instructions the seller provides. If the seller gives no instructions and the goods are perishable or rapidly losing value, the merchant buyer has a duty to sell them on the seller’s behalf, with reimbursement for care and sale expenses plus a standard trade commission or, if none exists, up to ten percent of gross proceeds.6Legal Information Institute. Uniform Commercial Code 2-603 – Merchant Buyer’s Duties as to Rightfully Rejected Goods

List Every Defect

A rejection notice should list every defect you intend to rely on. Under UCC 2-605, a buyer who fails to mention a defect that reasonable inspection would have revealed loses the right to use that defect as a basis for rejection, at least where the seller could have cured it if told in time.7Legal Information Institute. Uniform Commercial Code 2-605 – Waiver of Buyer’s Objections by Failure to Particularize Between merchants, the seller can demand a written statement of all defects the buyer plans to rely on, and any defect left off that list is waived. A thorough inspection and a detailed rejection letter are not optional extras.

The Seller’s Right to Cure

The perfect tender rule sounds absolute, but UCC 2-508 gives sellers a significant safety valve. If the contract’s delivery deadline has not yet passed, the seller can notify you of an intent to cure and then deliver conforming goods within the remaining time.8Legal Information Institute. Uniform Commercial Code 2-508 – Cure by Seller of Improper Tender or Delivery; Replacement

The cure right extends past the deadline in one situation: when the seller had reasonable grounds to believe the original tender would be acceptable, often where the seller shipped a substitute product thought to be comparable. In that case the seller gets a further reasonable time to deliver what was actually promised, as long as the seller notifies the buyer promptly.8Legal Information Institute. Uniform Commercial Code 2-508 – Cure by Seller of Improper Tender or Delivery; Replacement If you source replacements the moment you reject, without giving the seller a chance to cure, you can undermine your own legal position.

When Acceptance Happens

Acceptance is the event that cuts off the right to reject. Under UCC 2-606, you accept goods in three ways:4Legal Information Institute. Uniform Commercial Code 2-606 – What Constitutes Acceptance of Goods

  • You tell the seller, after a reasonable chance to inspect, that the goods conform or that you will keep them despite the nonconformity.
  • You have a reasonable chance to inspect but do not make an effective rejection. Inaction becomes acceptance once the inspection window closes.
  • You act inconsistently with the seller’s ownership — using the goods in production, reselling them, or otherwise treating them as your own.

Once acceptance occurs, you owe the contract price and cannot later reject those goods. You may still have a damages claim and, in some cases, the right to revoke acceptance.

Revoking Acceptance

Revocation is available when you discover, after accepting, that the goods have a nonconformity that substantially impairs their value. Two scenarios qualify: you accepted on the reasonable assumption that the seller would cure the problem and the seller did not, or the nonconformity was hidden or the seller’s assurances made it difficult to discover before acceptance.9Legal Information Institute. Uniform Commercial Code 2-608 – Revocation of Acceptance in Whole or in Part

The standard is harder to meet than initial rejection. A minor defect that would support rejection under the perfect tender rule will not support revocation. You must show substantial impairment, act within a reasonable time after discovering or being able to discover the problem, and the goods cannot have undergone a substantial change in condition unrelated to the defect. Prompt notice to the seller is required.9Legal Information Institute. Uniform Commercial Code 2-608 – Revocation of Acceptance in Whole or in Part

Where the Perfect Tender Rule Does Not Apply

Installment Contracts

The perfect tender rule does not apply to installment contracts, meaning agreements calling for delivery in separate lots to be separately accepted. UCC 2-612 replaces the “any respect” standard with a higher bar: you can reject a particular installment only if the defect substantially impairs that installment’s value and cannot be cured.10Legal Information Institute. Uniform Commercial Code 2-612 – Installment Contract; Breach If the seller offers adequate assurance of cure, you must accept.

Canceling the whole installment contract requires that the nonconformity substantially impair the value of the entire contract. Even then, accepting a later nonconforming installment without promptly notifying the seller of cancellation, or suing only over past installments while demanding future performance, can reinstate the contract.10Legal Information Institute. Uniform Commercial Code 2-612 – Installment Contract; Breach If your supply agreement involves recurring deliveries, rejecting an installment for a minor defect will likely be treated as a wrongful rejection.

Contractual Limits on Remedies

Section 2-601 opens with “unless otherwise agreed.” UCC 2-719 allows the parties to substitute alternative remedies, such as limiting the buyer to repair or replacement instead of outright rejection.11Legal Information Institute. Uniform Commercial Code 2-719 – Contractual Modification or Limitation of Remedy Clauses like these are common in equipment sales, technology contracts, and high-value manufacturing agreements.

There are limits. If the exclusive contractual remedy fails its essential purpose, such as a repair-or-replace clause where the seller cannot fix the defect after repeated tries, the buyer gets access to the full range of UCC remedies. Consequential damages can be excluded, but excluding consequential damages for personal injury in consumer goods transactions is presumed unconscionable.11Legal Information Institute. Uniform Commercial Code 2-719 – Contractual Modification or Limitation of Remedy Check the contract for a clause narrowing your remedies before assuming 2-601 gives you the right to reject.

Damages

After Rejection: Cover

A buyer who rejects and buys substitute goods can recover “cover” damages: the cost of the replacement goods, minus the original contract price, plus incidental or consequential damages, minus any expenses saved because of the breach.12Legal Information Institute. Uniform Commercial Code 2-712 – Cover; Buyer’s Procurement of Substitute Goods The replacement purchase must be made in good faith and without unreasonable delay. Failing to cover does not bar other damage formulas, but covering promptly is the cleanest path to recovery.

After Acceptance: Warranty Damages

A buyer who keeps nonconforming goods can recover the difference between the value of the goods as accepted and the value they would have had if they had been as warranted, measured at the time and place of acceptance, plus incidental and consequential damages.13Legal Information Institute. Uniform Commercial Code 2-714 – Buyer’s Damages for Breach in Regard to Accepted Goods To preserve the claim, you must notify the seller of the breach within a reasonable time after discovering it.2Legal Information Institute. Uniform Commercial Code 2-607 – Effect of Acceptance; Notice of Breach Late notice is the most common way buyers forfeit an otherwise valid claim after acceptance.
