About safety of wheel vehicles
Russia is an unique country and has unique requirements of safety. If you plan to trade with Russia, you should know and understand the Russian requirements for certification.
Your products have to meet Russian standards which are different and mostly not harmonized with the European or International standards. CE self-declaration is not sufficient in Russia and cannot replace the Russian Certificate of Conformity.
Basically, almost all consumer products require the mandatory certification. It includes all building materials, shoes, furniture, tableware and kitchenware, packaging materials, household and industrial equipment, etc.
