You should pay attention that although there are contract stamps, the official stamp is more commonly used in the signing of contracts in international trade because the official stamp is the symbol of a company’s legal operation. Only by holding the official stamp issued by public security can the company begin to do business. Therefore, using the official stamp can reduce business risks.

How to Stamp

2. If it is a multi-page contract, the stamp is required on the lower right corner of each page. And spread out the contract, stamp a cross-page stamp as is shown in the picture. This means the company will be responsible for every page of the contract.
