Short answer
Two indexed Estonian Competition Authority (Konkurentsiamet) pages directly address information exchange between competitors:
- the lists competitor agreements or cooperation—including information exchange—as a category of prohibited-agreement work; and
- the gives exchanging information about price changes as an example of cooperation that harms competition.
The overview also directs readers to the European Commission's , saying those guidelines cover agreements between competitors involving information exchange, joint production, joint purchasing, joint selling, standardisation, and research and development.
The two local pages do not define a general category called “commercially sensitive data,” identify every type of sensitive information, or provide a complete legality test for a proposed exchange. Price-change information is the clearest concrete example. The FAQ also discusses price fixing, market allocation and customer-group allocation, but it does not set out rules for aggregation, anonymisation, age of data, independent intermediaries or clean teams.
A separate says published decision copies omit trade secrets and other confidential information. That is a publication-redaction rule, not guidance authorising competitors to exchange confidential information.
The competition-supervision overview expressly names information exchange
Konkurentsiamet's overview explains that competition supervision addresses agreements that harm competition and abuse by undertakings with a dominant position. Under “prohibited agreements between undertakings,” it identifies three broad areas:
- agreements or cooperation between competitors, with procurement cooperation and information exchange as examples;
- agreements between undertakings operating at different levels, such as supplier–retailer distribution restraints; and
- competition-restricting activity by associations and industry bodies.
This establishes that information exchange is not merely an incidental topic. Konkurentsiamet places it within its description of horizontal competitor cooperation that may engage prohibited-agreement enforcement.
The page is still an overview, not a complete legal test. It does not say which data fields, time periods, market structures or safeguards change the assessment. Nor does it state that every communication between competitors is unlawful. Its function is to flag the category and route readers to the governing legislation and more detailed European guidance.
The FAQ identifies price-change information as the concrete risk
The FAQ defines cooperation harmful to competition as an agreement, concerted practice or decision of an association of undertakings that has an anti-competitive object or effect.
Its examples include:
- fixing the prices applied to business partners or customers;
- agreeing the territories in which undertakings operate;
- agreeing the customer groups to which products may be sold;
- exchanging information about price changes; and
- agreeing to discriminate between business partners or customers.
For information sharing, the price-change example is the most important indexed local proposition. It points toward forward-looking pricing information rather than saying that all public, historical or operational data is equivalent.
The page does not specify whether the concern is announced future prices, intended changes, current unpublished prices or another category. It also does not explain how market concentration, frequency, reciprocity or the level of aggregation affects the result. Those questions cannot be answered from the short FAQ alone.
Does the material discuss “commercially sensitive data”?
Only partially.
Neither of the two competition-supervision pages uses or defines a general term equivalent to “commercially sensitive information.” The indexed Estonian-language searches covered:
- informatsioonivahetus and teabevahetus—information exchange;
- hinnainfo and hinnateave—price information;
- äriliselt tundlik—commercially sensitive;
- strateegiline—strategic; and
- konfidentsiaalne—confidential.
The direct competition-supervision results were the overview's general information-exchange reference and the FAQ's price-change example. No indexed Konkurentsiamet guidance result supplied a taxonomy of sensitive data or a checklist for deciding when shared data is sufficiently aggregated, historical or anonymised.
It is reasonable in ordinary business language to describe non-public intended price changes as commercially sensitive. But the local FAQ does not itself define a legal category of that name. A compliance policy should quote the source's actual example and avoid attributing a broader definition to Konkurentsiamet.
The overview points to the detailed European framework
The overview links the Commission's 2023 Horizontal Guidelines and says they address competitor agreements concerning:
- information exchange;
- joint production;
- joint purchasing;
- joint selling;
- standardisation; and
- research and development.
That referral matters. It shows that Konkurentsiamet does not present its short webpage as the whole analytical framework. A real proposal should be tested against the current Competition Act, Article 101 TFEU where applicable, and the relevant sections of the Horizontal Guidelines rather than decided from the FAQ's single example.
The linked guideline was identified through the exact fetched Konkurentsiamet page. This Question 20 audit did not separately fetch the EU instrument through the MCP, so this article does not attempt to reproduce its full legal test. The source-supported conclusion is narrower: Konkurentsiamet directs users there for detailed treatment of horizontal information exchange.
Industry associations and intermediaries are not automatically safe
The overview separately includes competition-restricting activity by associations and unions among prohibited-agreement concerns. The FAQ's definition also covers decisions of an association of undertakings.
Accordingly, routing data through an industry body, credit bureau, platform or other intermediary does not place the arrangement outside the issue identified by Konkurentsiamet. The indexed local materials do not provide an exemption merely because competitors do not send files directly to one another.
At the same time, those pages do not analyse a particular intermediary model. They do not establish whether a proposed service's aggregation, access controls, delay, purpose limitation or output design is sufficient. Those facts require a separate, documented assessment under the detailed competition rules.
Confidentiality in merger publications is a different issue
The indexed merger archive begins by saying that trade secrets and other confidential information are omitted from published copies of decisions, with omissions marked by square brackets.
That statement concerns what the authority publishes after handling merger matters. It supports two limited conclusions:
- public decision copies may be incomplete because protected passages were redacted; and
- absence of a fact from the public copy does not prove that the authority never received or considered it.
It does not establish that exchanging the same information between competitors is permitted. Publication confidentiality and substantive competition risk answer different questions:
Conflating the last row with the first three would turn a redaction notice into substantive information-sharing guidance, which it is not.
What the indexed pages do not answer
The current Konkurentsiamet collection does not, through the two relevant local guidance pages, answer several operational questions needed for a data-sharing arrangement:
- whether the information is current, future-looking or genuinely historical;
- whether it identifies individual competitors, customers or transactions;
- whether aggregation prevents competitors from reversing the result;
- whether participation is reciprocal or compulsory;
- how often the information is exchanged;
- whether market concentration makes coordination more likely;
- whether an independent intermediary prevents access to raw competitor data;
- whether the output supports a legitimate efficiency and is necessary for it; or
- whether personal-data, confidentiality and financial-sector rules independently restrict the processing.
The absence of those points is a collection limitation, not evidence that they are legally irrelevant. A business should not turn “the local FAQ does not mention it” into a safe harbour.
A source-faithful review of a proposed exchange
A preliminary assessment grounded in the indexed material should record:
- Who competes with whom. Define the participating undertakings and the product and geographic markets rather than assuming every participant is or is not a competitor.
- What is exchanged. Identify every input and output field, especially intended price changes and other non-public variables that could reveal future commercial conduct.
- How the exchange occurs. Record whether competitors communicate directly or through an association, bureau, consultant or platform.
- Who can reverse the output. Test whether aggregates, small cohorts or repeated queries reveal a participant's underlying data.
- What decision the output enables. Determine whether it helps participants coordinate prices, customers, territories, bids, capacity or another competitive parameter.
- Which detailed authority applies. Move from the Konkurentsiamet overview to the current legislation and the linked Horizontal Guidelines before approving the design.
This is an evidence-preservation framework, not a conclusion that a particular exchange is lawful. The two indexed pages flag the risk and one concrete example; they do not supply enough facts or doctrine to clear a production data-sharing system.
Authority and currentness
The overview and FAQ are official explanatory webpages. The fetched records reproduce source-native “last updated” dates of 3 January 2024 and 5 June 2024 respectively. They are useful evidence of the authority's public explanation, but they are not themselves the Competition Act, an infringement decision or a court judgment.
The overview links the and identifies Articles 101–109 TFEU as relevant European competition provisions. Binding conclusions must be anchored in the applicable legislation and, where necessary, decisions or judgments.
Legalcode MCP audit
Production research used one Discover call, two successful Estonian-language Searches and three exact Fetches, all accepted calls using the configured bypass token and charging zero. One initial Search used stale top-level filter syntax and was rejected before retrieval; it was counted conservatively against the seven-call cap and then corrected using the live production schema.
The three authenticated full-text downloads confirmed the substantive distinctions above. They also exposed two ingest defects:
- The same page title appears three times as consecutive H1 headings in all three sampled Konkurentsiamet downloads. Existing was broadened with the cross-source evidence.
- The merger archive is labelled as one
Decisionwith 189,743 tokens, approximately 2,385 PDF links and hundreds of separate decision references. requests reclassification of the archive and document-level ingestion of the underlying decisions.
The second defect is material to this research: the archive's confidentiality notice is searchable, but the individual merger decisions are not represented by independent source references through that record. It cannot support a reliable claim that the collection contains document-level competition decisions merely because their links appear in one enormous page.
Conclusion
The indexed Konkurentsiamet overview and FAQ clearly place competitor information exchange within competition-supervision concerns. The FAQ's concrete example is exchange of information about price changes, while the overview points to the Commission's 2023 Horizontal Guidelines for detailed analysis.
The local pages do not define a comprehensive “commercially sensitive data” category or provide an operational safe harbour for aggregated, historical or intermediary-managed sharing. The merger archive's reference to trade secrets concerns redaction from public decisions, not permission to share confidential business information. A proposed exchange therefore requires fact-specific analysis under the binding rules and detailed horizontal guidance; the indexed local webpages alone are not enough to approve it.
