Historically Underutilized Business (HUB) is a company level diversity certification that is generally issued by a State Government to increase the amount of goods and services acquired by that state from HUBs. The program is in place to help businesses that are at least 51% owned by minorities such as Black, Hispanic, Asian-American, American Indian, Female or a Socially and Economically Disadvantaged person, Disabled-Owned or a Disabled Business Enterprise gain exposure to state procurement and contracting opportunities.

HUB certification is non-industry specific and is intended for organizations owned and operated at least 51% by a designated minority group.

Companies wishing to become HUB certified should contact the specific state from which the certification will be issued since eligibility requirements vary dependent upon the issuer. Generally, the organization must be owned and controlled by a member of a minority group; some requirements also put restrictions on the size of the organization or dictate that the business be located in that state for which the certification is being issued.
