Content of the Supplier’s Declaration of Conformity (SDoC)
​
BS EN ISO/IEC 17050-1:2010 (Supplier’s Declaration of Conformity — Part 1: General requirements)
​
​​This standard specifies the minimum information that a supplier’s declaration must contain so that it is valid, clear, and traceable.
​
The declaration should include:
​
-
Unique identification of the declaration (e.g., a reference number or code).
-
Name and contact details of the supplier issuing the declaration.
-
Identification of the object of the declaration (e.g., product, process, service, system, or person being declared).
-
Statement of conformity — clear wording that the identified object conforms with specified requirements.
-
Reference to the standards, specifications, or other normative documents against which conformity is declared.
-
Date and place of issue of the declaration.
-
Signature or equivalent confirmation by the supplier or authorised person.
In short, following these requirements ensures that a supplier’s declaration of conformity is unambiguous, properly identified, and linked to both the supplier and the relevant requirements, so that customers, regulators, or other interested parties can rely on it.
