A supplier declaration is a written statement from an ingredient supplier confirming facts a label cannot show — the source of an ingredient, whether any animal-derived or genetically engineered inputs were used, and which processing aids were involved. Certification reviews rely on these declarations because they document what actually goes into a product, closing the gaps that specification sheets and ingredient lists leave open.
In depth
A specification sheet describes what an ingredient is; a declaration confirms the facts a claim depends on. For a plant-based claim that means the origin of each input; for non-GMO it means the genetic-engineering status of a high-risk crop input; for gluten-free it means whether wheat, barley or rye touched the ingredient.
Declarations matter most for the things a label omits — processing aids, fining agents and the true origin of animal-derived ingredients. Without them, a reviewer would be guessing.
In a V-Cert desk review, supplier declarations are part of the document file a manufacturer submits. A missing or unclear declaration pauses the review until it is resolved — it is a gap to close, never a rejection.
