The State quality mark of the USSR (Russian: Государственный знак качества CCCP, translit. Gosudarstvennyi znak kachestva SSSR) was the official Soviet mark for the certification of quality established in 1967.  It was used to mark consumer, production, and technical goods to certify that they met quality standards and, in general, to increase the effectiveness of the production system in the USSR.  The goods themselves or their packaging were marked, as was the accompanying documentation, labels or tags. Rules of its use were defined by GOST, an acronym for 'state standard'
