The State quality mark of the USSR (Russian: Государственный знак качества СССР, transliteration Gosudarstvennyi znak kachestva SSSR) was the official Soviet mark for the certification of quality established in 1967.

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" (gosudarstvennyy standart), section 1.9-67 (April 7, 1967).

[2] The right to use the sign was leased to the enterprises for 2–3 years based on the examination of the goods by the State Attestation Commission (Russian: Государственная Атестационная Комиссия, Gosudarstvennaya Atestatsionnaya Komissiya) that should certify that the goods are of the "higher quality category".

[3] That is: Obtaining the sign allowed the enterprises to increase the state controlled price for the goods by ten percent.
