Camera Purchase Order Disclaimer
Global News Network sent CineTech Cameras a purchase order for studio cameras that listed quantity and price but said nothing about damages. CineTech replied with a timely acknowledgment that matched those terms and added a clause excluding liability for consequential damages. When the cameras later failed and Global sought lost advertising revenue, the exclusion operated only as a proposal for addition that did not automatically enter the contract.
Router Warranty Limitation Dispute
Northern Wireless offered Gate Broadband routers under a one-year repair-or-replace warranty that excluded consequential damages. Gate's purchase order accepted the quantity and price but added a service-credit formula for downtime. Northern shipped the routers without objecting, yet the added service-credit term remained only a proposal for addition that never became part of the agreement.

Common questions
Frequently Asked
4
When does an additional term in an acceptance become part of a contract between merchants?+
The term is treated as a proposal for addition. It enters the contract only if the offer does not limit acceptance to its own terms, the term does not materially alter the contract, and no timely objection is raised.
Supporting sources
Does merchant status alone cause every added term to bind the parties?+
No. Merchant status removes the need for express acceptance of the proposal but still requires that the term not materially alter the contract and that no timely objection be given.
Supporting sources
What happens to a consequential-damages exclusion added in a seller's acknowledgment when the buyer's order is silent on remedies?+
The exclusion is a proposal for addition. It does not automatically become part of the contract because it often materially alters the risk allocation and therefore requires express assent.
Supporting sources
How does a court decide whether an added term materially alters the contract?+
The court examines whether the term would cause surprise or hardship to a reasonable merchant in the position of the recipient, such as by shifting substantial risk or limiting remedies that would otherwise be available under the UCC.
