Conformity sign application rules

If goods have passed all procedures for conformity testing defined by the Technical Regulations of the Customs Union in the territory of a participating state of the EAWU and these can be documented with EAC certificates and/or EAC declarations, the manufacturer is entitled to mark his products with the uniform conformity mark EAC.

This can be attached to any type of packaging, product unit or accompanying document (technical passport, operating instructions).

It should be noted that the EAC mark of conformity is monochrome and the surface on which it is affixed provides colour contrast.

The Technical Regulations of the Customs Union define the framework for marking the product, packaging and accompanying documents with the EAC mark of conformity.
