Short answer. Yes, potentially. An implied warranty or condition as to quality or fitness for a particular purpose may be annexed by the usage of trade, meaning an established industry custom can create a warranty even though the contract itself never spelled it out in writing.

What the law says

An implied warranty or condition as to the quality or fitness for a particular purpose may be annexed by the usage of trade.

Trade usage can attach a warranty the contract never states

The statute allows a warranty to arise from a source the written contract itself is silent about: usage of trade. Where an implied warranty or condition as to quality or fitness for a particular purpose is a recognized feature of dealings in a particular industry, that usage can be annexed to the contract — attached to it as though it had been written in — even though the parties never expressly negotiated or stated it.

What makes something a qualifying "usage of trade"

The word usage points to an established, recognized practice within an industry or trade, not merely one party's personal expectation or a preference that has not become a genuine custom. For your industry's quality standard to annex a warranty under this article, it generally needs to be the kind of settled practice that parties dealing in that trade would reasonably expect to apply, rather than an idiosyncratic rule understood only by one side of the transaction.

This works alongside, not instead of, the written contract

This implied warranty by trade usage supplements what the contract says rather than overriding an actual, contrary agreement between the parties. If your contract had expressly addressed the quality standard in a way inconsistent with the trade custom, that express term would generally control. But where the contract is simply silent on the point, as you describe, this article allows the established trade usage to fill that silence with an implied warranty rather than leaving the standard unenforceable.

What you would need to establish

To rely on this article, you would need to show that the quality standard is genuinely a usage of trade in your industry — established, recognized, and known or reasonably knowable to parties dealing in that line of business — rather than simply an internal expectation your side held. This article does not itself define how a particular custom is proven to be a usage of trade; that is a factual question resolved by looking at how the industry actually operates, and vague assertions about how things are usually done are weaker evidence than a usage the trade itself would readily recognize and confirm.
