When a contract contains FAR 52.219-4, the so-called “HUBZone price preference” clause, a procuring agency must apply the HUBZone price preference by adding a factor of 10 percent to the price of all other offerors, except HUBZone firms and otherwise successful small businesses.
For procuring agencies, applying the HUBZone price preference is not optional. In Explo Systems, Inc., B-404952 (July 8, 2011), the GAO sustained a bid protest because the procuring agency failed to apply the HUBZone price preference.
