What Is UCC 1 303 

UCC 1 303 refers to Section 1 303 of the Uniform Commercial Code and is titled “Course of Performance, Course of Dealing, and Usage of Trade”.

UCC 1 303 is divided into six paragraphs as follows:

• UCC 1 303(a): Definition of course of performance
• UCC 1 303(b): Definition of course of dealing
• UCC 1 303(c): Definition of usage of trade
• UCC 1 303(d): The course of performance or course of dealing between parties or usage of trade can be used to give meaning to the agreement between the parties
• UCC 1 303(e): Interpretation rules for the course of dealing, course of performance, and usage of trade to be consistent with the agreement of the parties
• UCC 1 303(f): Course of performance can show a waiver or modification of any term inconsistent with the course of performance
• UCC 1 303(g): Admissibility of usage of trade evidence 

Objective of UCC 1 303 

The main objective of UCC § 1-303 is to provide the definition of three key terms:

• Course of performance
• Course of dealing
• Usage of trade

In essence, you’ll need to consider the legal definition provided under the Uniform Commercial Code 1 303 to interpret other provisions of the code.

UCC 1 303 Overview

Let’s look at the main paragraphs of UCC Section 1 303 to better understand the provision.

Course of Performance 

Section 1-303(a) defines the notion “course of performance”.

A course of performance is defined as a sequence of conduct, activity, or behavior between the parties when:

• The agreement between the parties necessitates repeated occasions for the parties to perform their obligation 
• A party performs its obligations without objecting to any particular issue or aspect related to the performance of the other party’s obligation 

In essence, the “course of performance” relates to a repeated pattern of behavior or conduct between the parties in the execution of their obligations under an agreement.

The course of performance relates to how the parties are executing their obligations under a current contract (not how they’ve done things in the past).

Course of Dealing

Section 1-303(b) defines the notion “course of dealing”.

A course of dealing is legally defined as a sequence of conduct or behavior adopted by the parties in the past that serves as the common basis for the establishment of a new transaction between them.

In other words, the parties have a common understanding of how the obligation is to be performed based on their sequence of conduct related to their past dealings.

A course of dealing relates to how the parties have done business with one another in the past (not during the performance of the current contract).

Usage of Trade

Section 1-303(c) defines the notion “usage of trade”.

A usage of trade refers to a type of practice of a method of dealing that is expected to be observed in a particular place, related to a particular vocation, or in a particular trade.

A party looking to establish a usage of trade must prove its scope as a matter of fact.

On the other hand, if the usage of trade is documented in a trade code or formal record, then the notion of trade is interpreted as a matter of law.

Waiver or Modification

Section 1-303(f) relates to the manner a party may show a waiver or modification of an agreement.

In essence, when the parties perform their obligations in a certain repeated way and where the other party had the opportunity to object to that way of performance but did not, then the course of performance can be considered as a possible waiver or modification to the agreement.

In other words, the course of performance can be recognized as a waiver or modification of the terms of the contract that are not inconsistent with it.

A course of performance refers to the repeated method or manner that contracting parties have dealt with one another to execute their obligations under a contract.

The course of dealing relates to the repeated method or manner that the contracting parties had dealt with one another under a prior contract forming the basis of their understanding of their current contractual performance.

Finally, the usage of trade is how things are done as per a particular vocation, in a place or location, or in a particular trade.
