Legal analysis
The official seal is the most effective of all seals and a symbol of legal person's rights. Unless there are special provisions in the law (such as stamping invoices), the official seal can represent the will of legal persons and sign contracts and other legal documents with high legal effect. All letters, official documents, contracts, letters of introduction, certificates or other company materials issued in the name of the company can use the official seal. Special seal for contract, which is used by the unit when signing the contract, can represent the unit within the scope of signing and bear the rights and obligations arising therefrom; In practical work, the official seal can be used instead of the special seal for the contract. The official seal of the unit belongs to the administrative seal, and it is in line with the norms to affix the official seal on the safety production agreement. Because the safety production agreement is a promise, and the contract is a transaction of mutual interest exchange, the two subjects are different, the official seal represents the legal person, and the contract seal represents the company's main body. It is precisely because the safety production agreement is a promise made and the contract is a transaction of mutual interest exchange that the safety production agreement is stamped with the official seal.
