Third-party certification is when an independent organization — not the company making a product and not the buyer purchasing it — verifies that a claim is true against a published standard. That independence is what gives the claim weight: a self-declared label rests on the maker's own word, while a third-party certificate rests on an outside review, a defined standard, and a record a buyer can check.
In depth
Conformity assessment is usually described in three parties. First-party is the producer declaring its own claim. Second-party is a customer or trade body checking a supplier. Third-party is an independent certifier with no stake in the sale, which is the arrangement most retailers and buyers treat as credible.
A credible third-party program has three things: a public standard that says what the claim requires, a defined review method, and a verifiable certificate. V-Cert publishes what each mark requires, reviews documents against it, and issues a certificate you can check by its number or QR code — so a buyer never has to take the claim on trust.
For the longer treatment, see the guide What third-party certification means. V-Cert issues its own marks and makes no equivalence claims to other certifiers' logos.

Frequently asked questions
Why is third-party certification better than self-declaration?
Because an independent body with no stake in the sale verifies the claim against a published standard and issues a checkable certificate, rather than the producer simply vouching for itself.
