31 CFR § 19.865 - How long may my debarment last?
(a) If the debarring official decides to debar you, your period of debarment will be based on the seriousness of the cause(s) upon which your debarment is based. Generally, debarment should not exceed three years. However, if circumstances warrant, the debarring official may impose a longer period of debarment.
(b) In determining the period of debarment, the debarring official may consider the factors in § 19.860. If a suspension has preceded your debarment, the debarring official must consider the time you were suspended.
