SF 33
Solicitation, Offer and Award
What It Is
SF 33 is the classic three-in-one cover page for procurements that aren't handled under the streamlined commercial rules. It is used in sealed bidding (FAR Part 14) and negotiated acquisitions (FAR Part 15) that follow the Uniform Contract Format. Like SF 1449, the same form carries the government's solicitation, the contractor's offer, and the eventual award, but it points to the full set of negotiated-procurement clauses rather than the commercial clause.
When You'll Use It
- Negotiated (FAR Part 15) or sealed-bid (FAR Part 14) acquisitions that aren't commercial buys.
- Larger or more complex set-asides that use the Uniform Contract Format (Sections A–M).
- As the offer page you sign and the award page the contracting officer signs.
Who Completes It
The contracting officer completes Blocks 1–8 (the solicitation) and signs the award; the offeror completes and signs Blocks 12–18 to submit a binding offer.
Key Blocks to Get Right
| Block / Section | What It Captures |
|---|---|
| Block 12 — Acceptance period | The number of calendar days you'll hold your offer open. Too short a period can get an offer rejected during a long evaluation. |
| Blocks 14–18 — Offeror identification & signature | Your firm's name, address, Unique Entity ID, and the authorized signature that makes the offer binding. |
| Block 19 — Amendment acknowledgment | Where you acknowledge every amendment (each issued on SF 30). Missing a material amendment can make a sealed bid non-responsive. |
| Blocks 26–28 — Award | The contracting officer's award signature; the contract is formed when this is executed. |
Common Pitfalls
- Treating SF 33 like a commercial buy — the clause set and evaluation process differ from FAR Part 12.
- Failing to acknowledge amendments in Block 19 on a sealed bid, which is generally a non-waivable defect.
- Submitting after the exact time in Block 9 — late offers are rejected except in narrow circumstances.
Frequently Asked
When is SF 33 used instead of SF 1449?
SF 33 is used for non-commercial sealed-bid (FAR Part 14) and negotiated (FAR Part 15) procurements that follow the Uniform Contract Format. SF 1449 is used for commercial products and services under FAR Part 12. If the solicitation is a commercial buy, expect SF 1449; if it's a complex non-commercial acquisition, expect SF 33.
What is the Uniform Contract Format?
It is the standardized Sections A–M structure (FAR 15.204) used to organize larger negotiated solicitations — from the solicitation form (Section A) through instructions to offerors (Section L) and evaluation factors (Section M). SF 33 is the Section A cover page.

Plain-English reference, not legal advice. Standard forms are periodically reissued and the FAR is amended for inflation and policy — always download the current edition from the GSA Forms Library and confirm requirements against the solicitation and your contracting officer before relying on it.
