Self-declaration vs third-party certification: the difference that matters to a buyer

A claim such as “no plant-protection treatment” freely chosen by a producer, and a label audited by an independent certification body, can look visually similar on a package — some text, sometimes an in-house logo. Their evidential weight nonetheless differs markedly. This guide clarifies that distinction, which overlaps with the notion of declared data developed in our guide on proof of origin.

Self-declaration: what it commits to, what it does not guarantee

A self-declaration is legally binding on whoever makes it — a deliberately false claim exposes them to penalties for misleading commercial practice. But it has not been checked by an independent third party before publication: its reliability rests solely on the producer’s good faith, with no prior external control mechanism.

Third-party certification: independent control

Third-party certification means that a certification body, separate from the producer, has checked compliance with a specification before authorising use of the label — see our guide on the audit process for the detail of that check. It is the independence of the controller, not merely the existence of a control, that distinguishes this approach from self-declaration.

That independence has a name and a reference that can be verified, and this is what lets you settle the question rather than argue it. For French official quality signs — Label Rouge, AOP, IGP, STG (the French forms of PDO, PGI and TSG), organic farming — the certification body must meet two cumulative conditions: be approved by the INAO (the French national institute for origin and quality) and be accredited by COFRAC (the French accreditation body) under the NF EN ISO/IEC 17065 standard. Accreditation explicitly covers its competence, independence and impartiality, and the INAO reassesses it every 12 to 18 months.

A “certification” whose body appears on neither of these two lists is therefore not necessarily false — but it is not of the same nature, and since both lists are public, the question is settled in a few minutes rather than by guesswork.

Why both have their place

Self-declaration is not a practice to avoid on principle — it suits simple factual information that the customer can check directly (a sales method, a practice visible during a farm visit) or a context of direct trust, typical of short-chain selling. Third-party certification becomes necessary when direct trust between producer and end buyer does not exist — a product sold through several intermediaries, where the end consumer has no way of checking the information personally.

How to tell them apart on a package

• A recognised certification logo (organic, Label Rouge, HVE — the French High Environmental Value certification; see our comparative guide) generally points to a public standard and an identifiable certification body.
• A text claim with no logo, or with an “in-house” logo created by the producer themselves, is most often a self-declaration, even when it is perfectly sincere.
• When in doubt, the certification body behind a recognised label can be identified and checked publicly — a claim that points to no identifiable body is, by elimination, a self-declaration.

What a specification should state

A buyer who requires a “certification” gains by stating explicitly whether they accept a documented self-declaration (with supporting evidence) or require formal third-party certification — the two wordings open very different compliance routes for the supplier, and leaving the ambiguity open multiplies the back-and-forth when responding to the call for tenders.

Common mistakes

• Confusing sincerity with certification — a self-declaration can be perfectly honest without being third-party certification.
• Requiring a “certification” without specifying its nature in a specification, creating an avoidable ambiguity.
• Relying on an “in-house” logo by mistaking it for a label audited by an independent body.

Checklist

1. Identify whether a claim points to an identifiable certification body, or is a self-declaration.
2. Check the body on the two public lists — INAO approval and COFRAC accreditation under ISO/IEC 17065. That is the decisive test.
3. Choose self-declaration for simple information that can be checked in a direct-sales context.
4. Favour third-party certification as soon as an intermediary stands between producer and end consumer.
5. State, in a specification, whether a documented self-declaration is enough or third-party certification is required — and under which accreditation standard, otherwise both routes remain open.
