Vendor Debarment and the Determination of Responsible Bidders

Responsible Bidders

This page provides information about vendor debarment within the State of Maine and explains how a responsible vendor is determined in the procurement process. 


The term “vendor debarment” and the determination that a vendor is not a “responsible bidder” both generally refer to situations where the State of Maine decides to no longer do business with a specific vendor for a period of time. Such a decision is made on rare occasions and at the sole discretion of the State, when vendor performance or activities cause the two parties to sever their existing or potential business relationship. The decision is normally made following a hearing, when required by statute, during which the impacted vendor is able to provide its perspective on the situation at hand.

Vendor Debarment and Federal Contracting

The federal government maintains a website known as the “System for Award Management” (, which includes a database of vendors who have been debarred from performance on federal government contracts. From here users can select "Data Access" and scroll down to "Public Search" to find the most recent lists. 

The website can be used as a reference tool both for State agencies and vendors seeking partnerships with other vendors. Please note, appearance on this website does not necessarily mean the listed vendor has been debarred in the State of Maine.

State of Maine contracts that use federal funds and are valued over $25,000 require the selected vendor to self-certify that it has not been debarred from doing business with the federal government. The vendor debarment self-certification form is found on the Division of Procurement Services website under the Forms page. The full title of the document is: “Certification Regarding Debarment, Suspension and Other Responsibility Matters Primary covered Transactions.”
