FAR 52.219-1
Small Business Program Representations
What it says
Requires the offeror to represent its size and socioeconomic status (small business, SDB, WOSB, HUBZone, SDVOSB) as of the date of the offer, tied to the NAICS code and size standard in the solicitation.
Why it matters on DIBBS
Your SAM registration reps flow into every DIBBS quote. Misrepresenting size status carries severe penalties — keep SAM current, especially after growth or affiliation changes.
