Explanatory Letters

Opinions (known in business as “exemption letters of VNIIS” (All-Russia Scientific Research Institute for Certification) are prepared in accordance with the assigned terms of execution chosen by the applicant.

There are two types of exemption letters:

  1. Letters meant for submission to customs authorities of the Russian Federation.

    An exemption letter “for customs” is a clarification for customs about the need for mandatory certification of products when they are released into the customs territory of the Customs Union (Russia, Kazakhstan, and Belarus).

    The letter contains a reference to the shipping document whereby the products are imported to the territory of the Customs Union.

  2. Letters for trading.

    An exemption letter “for trading” is a newsletter for the products to be marketed in the territory of the Russian Federation, which informs that the products provided are not on the list of products subject to mandatory certification according to OKP (All-Russian Classification of Products).

    VNIIS does not guarantee a positive response. The need for verification of conformity of the products is determined by experts of VNIIS on the basis of normative documents specifying mandatory requirements for the products.
