Does the tender need to be stamped?

The law does not mandate that tender documents, bids or contracts must be stamped with a stamp; in the official document processing specifications and general operating guidance for application documents, there is no requirement that documents must be stamped with a stamp. In other words, tender documents, tender documents or contracts without seals will not affect their validity as long as they can reflect the completeness and coherence of the written expression. It is completely unnecessary to stamp various documents and documents (including bidding documents and contract agreements) on the actual bid. The documents, documents, contracts, agreements, offers, etc. held by the counterparty need to be consistent with the original documents of the issuer. It is valid only if it is consistent. If a dispute arises due to non-consistency, except for the counterparty's valid evidence for defense, it should generally be inferred that the original document or the document held by the issuer shall prevail. I have never seen documents from the central government, state agencies, or party committees and governments at all levels stamped with seals.

However, in real life, there are often contracts, agreements, tenders, bids, offers and other documents or documents, especially court judgments, rulings and mediation documents that are not glued. When it is installed or threaded, it is usually stamped with a seam seal, whose function is to prevent "external risks". Because the seam seal is affixed, the contract can be unfolded as a whole and the seam seal can be restored to the original seal. Therefore, it can prevent the counterparty from changing the content of the contract, and avoid unnecessary troubles and disputes caused by changing the content of the contract or denying the content of the contract. "Extracorporeal risks."

As the name suggests, the seam seal should be pressed to the side seam when stamping. When affixing an ordinary official seal, it is required to "ride the year and the month", but the seal seal requires "riding the seam", that is, the official seal must be evenly stamped on the middle seam of two pages of foldable paper, half of which is kept as a stub, and the other half is used as a voucher for verification. When facing each other, the official seal should be complete and unified. Like the "steel seal", it has the function of preventing the addition or deletion of page numbers in the document, that is, it can be seen whether there are more or less pages, preventing embedding or adding pages to maintain the integrity of the document.

Under modern handling conditions, there are many ways to replace the "seam seal" function. For example, when printing documents and documents, use folding or full-page format, and print all contents on On indivisible paper; plastically sealing sets or multiple pages of documents; using special paper or hiding special marks under the formal text of the document, etc.
