Management of Controlled Items

Many kinds of chemicals and equipment are regulated by different authorities. These controlled items may require licenses to store or use, and some have a maximum allowable quantity (MAQ) that can be kept in the School. To ensure that the requirements are followed, these chemicals and equipment must be tracked.

If any item you are purchasing via Ariba is a controlled item, please indicate it as such by clicking ‘Yes’ in the Purchase Requisition.
