What Does Commercial in Confidence Mean? (2026 Update)

Commercial in confidence means business information that is shared for a limited purpose and must not be passed on or used for anything else without the owner’s consent. Think pricing, margins, tender methodology, customer lists and product plans. The label tells the recipient to keep it private, but the label alone does not make it legally protected.

Here’s the uncomfortable bit. Most businesses stamp “commercial in confidence” on a quote or proposal, hit send, and assume they’re covered. Then a supplier shares the pricing with a competitor, or a government agency publishes contract details, and they find out the stamp was doing far less work than they thought.

What does commercial in confidence mean in practice?

Break the phrase in two. “Commercial” means business information with money attached to it. “In confidence” means it was handed over on trust, for one purpose only.

So when you mark a tender response, a pitch deck or a supplier quote as commercial in confidence, you’re saying: you can read this to do the job we’re discussing, and nothing else. You can’t share it, reuse it or hand it to your next client.

You’ll see it written a few ways: “commercial-in-confidence”, “commercially confidential”, “CIC” or plain “confidential”. None of those spellings changes the legal position. What matters is the information itself and how you shared it.

What counts as commercial-in-confidence information?

The test is simple. Would a competitor pay to see it, and would you lose something if they did? If yes to both, it probably qualifies. Common examples include:

• Internal costings, profit margins and pricing structures that reveal how you make money
• Delivery methodology, processes and know-how that set you apart from competitors
• Customer and supplier lists, especially with contact details and buying history
• Product roadmaps, prototypes, source code and unpublished designs
• Financial forecasts, investor materials and acquisition plans
• Trade secrets such as recipes, formulas and technical specifications

What doesn’t count, even if you label it

Anything already public. If your price list sits on your website, calling it commercial in confidence in a quote won’t make it secret again. The same goes for information a competitor could easily work out for themselves.

Over-labelling is the other trap. Stamp every email and every attachment, and you weaken your argument that any particular document was genuinely sensitive. Be selective. A court is far more persuaded by a business that marked three documents carefully than one that marked three hundred out of habit.

Commercial in confidence vs confidential: what’s the difference?

In everyday business, people use them as if they mean the same thing. Legally, they sit at different levels. “Confidential information” is a legal concept that courts will protect. “Commercial in confidence” is a marking you put on a document to show you believe it falls into that category.

Searches for “in confidence meaning” are climbing, and it’s easy to see why. A handful of similar-sounding labels do very different jobs:

Label	What it signals	Does it protect you on its own?
Commercial in confidence	Business information shared for a limited purpose	No. It’s evidence of your intention, which helps, but you need a contract or the equitable duty of confidence behind it
Confidential	Information that isn’t public and has value	As a marking, no. As a legal status, courts will protect genuinely confidential information
In confidence	A request to keep something private, often said verbally	Same as above. Spoken information can still be protected if the circumstances make the confidence obvious
Without prejudice	Settlement negotiations in a dispute	Different purpose entirely. It stops offers being used as evidence in court, not shared with third parties
Legally privileged	Communications with your lawyer for legal advice	Yes, if the privilege genuinely applies. Slapping the label on a non-legal email does nothing

The mistake to avoid: using “without prejudice” when you mean “commercial in confidence”. Founders do this in pricing negotiations all the time, and it doesn’t stop the other side sharing your numbers.

Is commercial in confidence legally binding?

Not by itself. The marking becomes enforceable when it’s backed by one of two things: a contract, or the equitable duty of confidence. Ideally both.

Protection through a contract

This is the reliable route. A mutual NDA or a confidentiality clause in your main contract spells out exactly what’s confidential, how it can be used, who it can be shown to and for how long.

Timing matters more than most people realise. An NDA signed after the pitch meeting may not cover what you said in the meeting. Get it signed first, then share. If only you are handing information over, a one-way NDA is usually the cleaner fit.

Protection without a contract: the equitable duty of confidence

Forgot the NDA? You may still be protected. Australian courts can stop someone misusing information even where nothing was signed. To succeed, you’ll generally need to show:

1. You can identify the information with some precision (not just “everything we discussed”)
2. It has the quality of confidence, meaning it isn’t public or common knowledge
3. The recipient received it in circumstances where they knew, or should have known, it was confidential
4. They’ve used or disclosed it without your consent, or are threatening to

This is exactly where a commercial in confidence marking earns its keep. It’s strong evidence for the third element. Combine it with restricted access and a record of who received what, and your position gets much stronger.

A common myth about CBA v Barker

You’ll find older articles (including an earlier version of this one) suggesting the High Court’s 2014 decision in Commonwealth Bank of Australia v Barker means courts won’t protect confidential information unless a contract expressly says so. That’s not what the case decided.

Barker was about employment. The High Court held that Australian employment contracts don’t contain an implied term of “mutual trust and confidence“, a broad duty about how employers and employees treat each other. It said nothing to remove the separate, long-standing protection equity gives to confidential information. Different “confidence”, different rule.

What about employees and contractors?

Employees already owe duties not to misuse their employer’s confidential information, and company officers and employees can’t improperly use information gained through their position under the Corporations Act 2001 (Cth). Contractors are the gap. They often work for your competitors too, and general law protection is thinner.

Don’t rely on implied duties for either group. Put express obligations in a contractor agreement and your employment contracts, and back them with a written confidentiality policy so staff know what “confidential” covers day to day.

How do you protect commercial-in-confidence information?

You don’t need a 40-page security manual. A short, repeatable routine covers most small businesses:

1. List what actually matters. Before any pitch, tender or due diligence, write down the five or six things that would hurt if they leaked. That list becomes the scope of your NDA.
2. Sign before you share. NDA first, data room second. If you’re already under contract, check the confidentiality clause covers the new information.
3. Mark it properly. Use a consistent header or footer, and add a confidential email disclaimer to correspondence that carries sensitive attachments.
4. Share the minimum. Does the supplier need your full customer list, or would a redacted sample do the job?
5. Keep a paper trail. Note what was shared, when and with whom. If something leaks, this record does a lot of heavy lifting.
6. Ask for it back. When a deal falls over, request return or destruction of your material in writing. Most people never do this.

Example commercial in confidence notice wording

For a document header or footer:

COMMERCIAL IN CONFIDENCE. This document is provided by [Your Business Pty Ltd] to [Recipient] solely to [evaluate our proposal for X]. It must not be copied, disclosed or used for any other purpose without our prior written consent.

For an email footer, keep it short. Nobody reads a 200-word disclaimer, and courts know it.

This email and any attachments are commercial in confidence and intended only for the named recipient. If you received it in error, please delete it and let us know.

What a good confidentiality clause covers

Whether it sits in an NDA or your main contract, check for these six things:

• A clear definition covering written, verbal and electronic information, plus notes and analysis the recipient creates from it. Getting this wrong is the most common NDA failure, so it’s worth reading how to define confidential information in an NDA.
• A purpose limit so the information can only be used for the agreed project
• Permitted disclosures to advisers who are bound by confidentiality, and where the law requires it
• Standard exclusions for information that’s already public, already known or independently developed
• A duration, usually two to five years for commercial information, longer for genuine trade secrets
• Return or destruction obligations when the relationship ends

What happens to commercial in confidence information in a government tender?

This is where private-sector instincts let people down. With a business, you negotiate confidentiality however you like. With government, transparency is the default, and confidentiality has to be justified.

If you’re bidding for government work, plan for parts of your contract to become public before you write a word of your response.

The Commonwealth Confidentiality Test

Federal agencies assess every supplier confidentiality claim against a four-part test set out in the Department of Finance’s guidance on confidentiality throughout the procurement cycle. All four must be met:

1. The information is specifically identified
2. It is commercially sensitive and not already public
3. Disclosing it would cause unreasonable detriment to you or someone else
4. It was provided on the understanding it would stay confidential

Two things in that guidance surprise most tenderers. First, a clause saying “all information is confidential” fails the first criterion outright. Second, plenty of commercial terms are generally treated as not confidential at all, including indemnities, payment arrangements, performance measures, liquidated damages and the price of individual items.

What does tend to pass? Internal costings, profit margins, pricing structures that reveal whether you’re making a profit, and proprietary methodology that would hurt your chances in future tenders if a competitor saw it.

Freedom of information requests

Anyone can request documents from a federal agency under the Freedom of Information Act 1982 (Cth), including your competitors. Your tender documents can be caught.

Two exemptions do most of the work for businesses. Section 47 exempts trade secrets and commercially valuable information whose value would be destroyed or diminished by release. Section 47G is a conditional exemption for business information, which means the agency must also weigh the public interest before withholding it.

The useful part: under section 27, an agency must generally consult you before releasing documents containing your business information, so you get a chance to argue against release. Respond to that letter quickly and specifically. “It’s commercial in confidence” is not an argument. “This table shows our labour margin by role, which a competitor would use to undercut our next bid” is.

AusTender and the Senate Order

Commonwealth contracts worth $10,000 or more are reported on AusTender, including the supplier’s name and the contract value. Separately, under a Senate Order, federal agencies publish lists of contracts worth $100,000 or more that note whether they contain confidentiality provisions and why.

In other words, your total contract price will almost certainly become public. Plan for that. Protect the breakdown that sits behind the number instead.

State and local government contracts

Each state runs its own right-to-information regime. In NSW, for example, agencies and councils must publish details of contracts with private businesses worth $150,000 or more on a government contracts register, and a copy of the contract itself once it reaches $5 million. The commercial-in-confidence provisions of a contract don’t have to be published, but the agency, not you, decides what fits that description.

How to claim confidentiality in a tender response

• Use the confidentiality schedule or form in the tender pack if there is one. Don’t invent your own wording when the agency has asked for a specific format.
• Name each item separately (for example, “Schedule 3, rate card build-up”) rather than claiming whole sections.
• Explain the harm in one or two sentences per item, linking it to the four criteria.
• Keep a copy of exactly what you claimed. If an FOI consultation letter turns up two years later, you’ll need it.

Where businesses get commercial in confidence wrong

Sharing first, signing later. The excitement of a promising lead makes people skip the paperwork. Information disclosed before the NDA may sit outside it, leaving you to rely on equity alone.

Treating the label as the protection. A footer is evidence. It isn’t a contract. If the relationship matters, so does the agreement.

Using a mutual NDA when only one side discloses, or the reverse. It isn’t fatal, but it creates obligations you don’t need or leaves gaps you do. Our guide on choosing a mutual or one-way NDA walks through the call.

Assuming government will keep the whole contract secret. It won’t. Write your tender knowing the headline numbers will be published.

Forgetting your own team. Leaks happen through departing staff and contractors far more often than through corporate espionage. Exit checklists that recover devices and revoke access are dull, and they work.

What can you do if someone breaches commercial in confidence?

Move fast. Confidential information loses value the longer it circulates, and courts look less kindly on owners who wait.

1. Preserve the evidence: emails, file access logs, the NDA and your record of what you shared.
2. Send a letter of demand requiring them to stop, return your material and confirm in writing.
3. If the misuse is ongoing or serious, ask a lawyer about an urgent injunction. In many cases, stopping the leak matters more than damages.
4. Consider damages or an account of profits where you’ve suffered real loss.

Our guide to breach of confidence covers the elements in more detail. If the stakes are high, speak to a contract lawyer before you send anything, because a badly worded demand letter can make things worse.

Frequently asked questions about commercial in confidence

What does commercial in confidence mean in Australia?

It means business information shared for a specific purpose that the recipient must keep private and not use for anything else. It’s a label, so its legal force comes from a contract such as an NDA, or from the equitable duty of confidence.

Is a commercial in confidence marking legally binding?

Not on its own. It helps prove the recipient knew the information was confidential, which matters if you go to court. For reliable protection, pair the marking with a signed NDA or a confidentiality clause in your contract.

What is the difference between commercial in confidence and confidential?

“Confidential information” is a legal category courts will protect if the information isn’t public and was shared in confidence. “Commercial in confidence” is a marking that says you consider business information to fall into that category.

What does “in confidence” mean?

It means information is shared on trust and shouldn’t be passed on. Verbal information can be protected too, if the circumstances made it clear the conversation was private. Writing it down afterwards strengthens your position.

Can I protect commercial information without an NDA?

Sometimes. Courts can restrain misuse of genuinely confidential information shared in circumstances that made the confidence obvious, even with nothing signed. It’s harder to prove and more expensive to enforce, so an NDA is still the better plan.

Can the government release my commercial in confidence information?

Yes, in some cases. Contract values are routinely published, and documents can be requested under FOI. Trade secrets and commercially valuable information can be exempt, and agencies must generally consult you first, so respond with specific reasons.

How long do commercial in confidence obligations last?

As long as your contract says, or for as long as the information stays confidential under the general law. Two to five years is common for commercial information. Trade secrets can justify longer.

Should I put commercial in confidence on my emails?

Only on emails that carry genuinely sensitive information. A short, targeted disclaimer is more credible than a long one on every message, and it won’t replace an NDA for anything that really matters.
