Common Examples

Credit Union Grants Immediate Access
Redwood Bank allowed a member to draw immediately on three checks exceeding $120,000 drawn on an out-of-state insurer. The bank followed its usual policy and expert testimony showed similar practices at other credit unions. A jury found the bank failed the standard because it neither investigated the checks further nor placed a hold to permit irregularities to surface.
Seller Raises Price Without Notice
Shell Oil notified Nanakuli Paving of a $32 price increase effective the next day in a letter received four days later. Trade practice in the asphaltic paving industry required advance notice of price changes. The court held Shell had not observed reasonable commercial standards of fair dealing by departing from that established usage.

Buyer Fails to Disclose Trade Usage
Oloffson purchased corn from Coomer without disclosing a known trade usage requiring prompt notice of a seller's intent to cover. Coomer therefore missed the commercially reasonable window to protect himself. The court concluded Oloffson's silence violated the standard of fair dealing between merchants.

Common questions
Frequently Asked
4
How does the reasonable commercial standards component differ from honesty in fact?+
The phrase supplies an objective test that measures conduct against industry norms of fairness. A party may be honest in fact yet still fail the standard if its actions deviate from accepted commercial practices of fair dealing.
Does ordinary negligence automatically violate the standard?+
No. The standard addresses unfairness rather than mere carelessness. A party's failure to investigate or follow best practices violates the standard only when the conduct amounts to a departure from norms of fair dealing.
Must a merchant conform to every customary practice in the trade?+
No. The standard requires observance only of those practices that embody fair dealing. Courts may reject a trade usage that itself falls below reasonable commercial standards of fairness.
Can a party satisfy the standard by following its own internal policy?+
Only if the policy itself aligns with reasonable commercial standards of fair dealing. Expert testimony that many firms follow a similar policy is relevant but not conclusive when the policy permits conduct that treats other parties unfairly.
