When SBA receives a size protest, the SBA Area Director for Government Contracting, or designee, will notify the contracting officer, the protested concern, and the protestor that the protest has been received. If the protest pertains to a requirement involving SBA's HUBZone program, the Area Director will also notify the D/HUB of the protest. If the protest pertains to a requirement set aside for WOSBs or EDWOSBs, the Area Director will also notify SBA's Director for Government Contracting of the protest. If the protest pertains to a requirement involving SBA's SBIR or STTR programs, the Area Director will also notify the Associate Administrator, Investment Division. If the protest involves the size status of an SDB concern (see part 124, subpart B of this chapter) the Area Director will notify SBA's Associate Administrator for Business Development. If the protest pertains to a requirement that has been reserved for competition among eligible 8(a) BD program participants, the Area Director will notify the SBA district office servicing the 8(a) concern whose size status has been protested. SBA will provide a copy of the protest to the protested concern together with SBA Form 355, Application for Small Business Size Determination, by certified mail, return receipt requested, or by any overnight delivery service that provides proof of receipt. SBA will ask the protested concern to complete the form and respond to the allegations in the protest.

When SBA receives a request for a formal size determination in accord with § 121.1001(b), SBA will provide a blank copy of SBA Form 355 to the concern whose size is at issue.

The protested concern or concern whose size is at issue must return the completed SBA Form 355 and all other requested information to SBA within 3 working days from the date of receipt of the blank form from SBA. SBA has discretion to grant an extension of time to file the form. The firm must attach to the completed SBA Form 355 its answers to the allegations contained in the protest, where applicable, together with any supporting material.

If a concern whose size status is at issue fails to submit a completed SBA Form 355, responses to the allegations of the protest, or other requested information within the time allowed by SBA, or if it submits incomplete information, SBA may presume that disclosure of the information required by the form or other missing information would demonstrate that the concern is other than a small business. A concern whose size status is at issue must furnish information about its alleged affiliates to SBA, despite any third party claims of privacy or confidentiality, because SBA will not disclose information obtained in the course of a size determination except as permitted by Federal law.
