The official seal is generally circular, and the special seal for industrial and commercial enterprise contracts is circular regardless of economic components. The official seal refers to the seal used by organs, organizations, enterprises and institutions. ? 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.

Effectiveness of official seal

The official seal is the most effective of all seals and a symbol of legal person's rights. In the current legislative and judicial practice, it is an important criterion to judge whether a civil activity is established and effective to examine whether it is stamped with the official seal of a legal person. Unless there are special provisions in the law (such as the stamping of invoices), the official seal can represent the will of the legal person and can sign contracts and other legal documents with high legal effect.
