SBD 9 — The Certificate of Independent Bid Determination, Explained

SBD 9 is the Certificate of Independent Bid Determination: a one-page form on which you certify that you priced and prepared your bid without colluding with any competitor. Since 31 March 2022 it sits inside the SBD 4 Bidder's Disclosure, so fill in a separate SBD 9 only if your tender pack lists it.

SBD 9 — The Certificate of Independent Bid Determination, Explained — SBD 9 — plain-English guide for South African government tenders.

What SBD 9 certifies

The certificate is a signed declaration that the bid was arrived at independently. In substance you certify that there has been no consultation, communication, agreement or arrangement with any competitor about:

prices — yours or theirs, including formulas or discounts used to work them out;
the intention to bid — no agreement that one of you would bid and the other stay out;
the content of the bid — quality, quantity, specifications or delivery particulars;
dividing up the work — no arrangement about who bids for which contracts or in which areas.

It is signed by the person authorised to sign the bid, and like every declaration in the pack, its power comes from the consequences of signing it falsely rather than from the questions it asks.

Why the state asks for it — collusive tendering

SBD 9 exists because bid rigging is a real and prosecuted problem in public procurement. Collusive tendering — competitors agreeing prices, taking turns to win, or submitting deliberately losing "cover" bids to dress up a rigged result — is a prohibited practice under the Competition Act, and the penalties reach both the businesses and the contracts involved. The certificate puts every bidder's independence on record in writing, so a bid later shown to be collusive is not just a competition-law problem but a false declaration to the state as well.

One boundary is worth knowing: a joint venture or subcontracting arrangement that is disclosed openly in the bid is not collusion. The certificate targets secret coordination between supposed competitors — not partnerships the buyer can see and assess.

SBD 9 is now usually inside SBD 4 — match your pack

Since the 31 March 2022 consolidation, the current SBD 4 Bidder's Disclosure carries the independent-bid-determination certificate as one of its sections, alongside the old conflict-of-interest questions and the past-conduct declaration that used to be SBD 8. The rollout is uneven, so the rule is the one that governs every SBD form: complete whichever version is in the pack in front of you. If your pack lists SBD 9 as its own returnable, complete and sign it. If it only contains the consolidated SBD 4, signing that form covers it — there is no separate SBD 9 to hunt for.

How to fill in SBD 9, field by field

The standalone SBD 9 is a one-page certificate with four blanks and a signature block. In the order they appear:

Bid number and description — copy both exactly as they appear on SBD 1 and the tender cover page. A mismatch here is how one bid's certificate ends up in another bid.
Name of the institution — the organ of state that issued the invitation (the department, municipality or state-owned company), not the eTenders portal.
Name of the bidder — your registered business name as it appears on your CSD registration; for a joint venture or consortium, the JV's name.
The certification paragraphs — read them; there is nothing to fill in. By signing you certify you did not agree prices, quantities or whether to bid with any competitor, and that you did not show your price to another bidder before the closing date. If you did consult another bidder — for example a subsidiary also bidding — the form asks you to disclose it in full rather than leave it out.
Signature, date, position and name of bidder — signed by a person authorised to act for the business, with their job title ("Director", "Member") in the position field. An unsigned SBD 9 is treated as not submitted.

Two sister companies submitting near-identical prices for the same tender is the classic way to fail this certificate — each bid needs its own independently arrived-at price.

Where SBD 9 comes from

Like every Standard Bidding Document, SBD 9 is not something you download separately — it arrives inside the tender pack from the National Treasury eTenders portal, and the returnable-documents schedule tells you whether that pack requires it. See how all the SBD forms fit together →

Working through a real pack — every form, in the order evaluators check them — is what the Tender Ready SA toolkit walks first-time bidders through.

Frequently asked questions

What is SBD 9?

SBD 9 is the Certificate of Independent Bid Determination — the Standard Bidding Document on which you certify that your bid was priced and prepared independently, without any agreement or communication with competing bidders.

Do I still need to submit SBD 9?

No — only if your tender pack lists it as a separate returnable. Since 31 March 2022 its content sits inside the consolidated SBD 4 Bidder's Disclosure, so most current packs need only that form. Older packs still carry SBD 9 separately — if yours does, complete and sign it.

What is bid rigging?

Competitors secretly coordinating a tender: agreeing prices, agreeing who will win, submitting deliberate cover bids or dividing contracts between them. It is a prohibited practice under the Competition Act, and SBD 9 is the declaration that you did none of it.

Is a joint venture collusion under SBD 9?

No. A joint venture or subcontracting arrangement disclosed openly in the bid is a partnership the buyer can assess, not secret coordination. The certificate targets undisclosed agreements between supposed competitors.
