Why Do We Use Commodity Codes?

Commodity codes are essential for accurate reporting and accounting. They help classify purchases, track assets, and determine the lifespan of items for depreciation. Using the correct code ensures precise financial data and effective asset management.

What is a Commodity Code?

A commodity code is a standard classification system used to categorize equipment and other assets purchased by the university. These codes ensure that each item is assigned the correct useful life for financial reporting and depreciation purposes. Using the correct commodity code is essential for accurately classifying and tracking university assets.

Major Class Codes and Their Importance

Major Class Codes represent the broadest categories used to classify purchases, serving as an overarching framework for organizing items. Each Major Class Code encompasses a range of individual commodity codes, which provide more specific details about the item.

For example, if you were purchasing oranges, the Major Class Code would be 01900 (Agricultural Crops and Grains, including Fruits, Melons, Nuts, and Vegetables). The specific Commodity Code for oranges would then be 01941, which identifies the item as Fruits, Citrus.

This hierarchical structure ensures clarity and consistency in classifying purchases, making it easier to manage and track procurement data.
