One of the rules we get asked about the most as government contracts attorneys is what’s known as the nonmanufacturer rule, 13 C.F.R. § 121.406 (So much so that we felt it wise to go over the rule in one of our “Back to Basics” posts to help clear some things up). It’s pretty understandable why: It has numerous provisions, exceptions, and requirements that can make it pretty difficult to follow. It also shows up in two different regulations: 13 C.F.R. § 121.406 as mentioned above, as well as FAR 19.505. Unfortunately, this often leads to contractors getting tripped up by the rule, either not realizing it applies where it does or, as we’ll explore here, thinking it applies where it doesn’t. Recently, SBA addressed a size protest that asserted the awardee didn’t meet the requirements of the nonmanufacturer rule, and noted to the unfortunate protestor that the rule didn’t apply for the procurement anyways.
