Because the Ministry of Public Security has not made uniform provisions on the engraving procedure, the provisions on the engraving procedure vary from place to place.
China has a perfect judicial management system for the management of official seals, and any private engraving is illegal and criminal. A seal forged without a legal subject shall be punished as the crime of forging the subject.
Legal basis: Article 10 of the Measures for the Administration of Public Security of Seals shall be engraved by the engraving unit approved by the public security organ; The engraving unit shall register the engraved seal with the public security organ before using it.
