Declaration of Conformity
A Declaration of Conformity (DoC) is the manufacturer's signed statement listing the exact directives or regulations a product meets, the harmonised standards applied, and who takes legal responsibility. It is the paperwork behind a CE or UKCA mark, not the mark itself.
Why it matters
Market surveillance authorities can ask for the DoC at any time, and a missing or wrong DoC is treated the same as having no conformity assessment at all. Every regulation on this site that leads to CE or UKCA marking requires one, with its own list of mandatory fields.
