If the enterprise is a Sino-foreign joint venture or Sino-foreign cooperative enterprise, it must hold a letter of introduction issued by the Chinese side, go to the public security organ at or above the county level where the unit is located to handle the notice or letter of introduction for engraving the seal, and then engrave it at the engraving factory or engraving shop designated by the public security organ with the notice or letter of introduction.
Engraving requires an engraving unit with a special trade license to engrave the official seal. It is illegal to engrave the official seal privately, and the engraved seal has no legal effect.
