Common questions

What is a SAM.gov exclusion?
A SAM.gov exclusion bars a business from receiving US federal contracts and financial assistance. Exclusions are issued for fraud, contract default, criminal activity, or tax delinquency. Hiring an excluded vendor for federally funded work can result in fines for your organization.
What does an OSHA violation mean for a vendor?
An OSHA violation means the Occupational Safety and Health Administration cited the business for a workplace safety infraction. Repeated or serious violations can signal management problems or financial liability. Construction and logistics vendors are the most frequently inspected.
