The EurAsian Conformity mark (EAC) is a product marking to indicate that the products conforms to all technical regulations of the Eurasian Customs Union assessment procedures. This means that it meets all requirements and technical regulations applicable to the product, and that it can be serviced in all service centers of the producer in the territory of all Customs Union member countries (Belarus, Kazakhstan Russia, Armenia and Kyrgyzstan). The mark came into use in August 2013.
Before this marking came into use, the prevalent product marking in some member countries was GOST 50460-92: Mark of conformity for mandatory certification.
STAMFORD products can be supplied on request with the EAC conformity mark to assist the import of products into the Eurasian Customs Union member countries.
