In the business realm in China, the official company chop, also known as a company seal, holds substantial importance. This stamp is the authoritative mark businesses use to authenticate documents, contracts, and transactions. Given its critical role, it is essential for any business operating in China to have a comprehensive understanding of the function and operational dynamics of company chops. This article provides an in-depth overview of the subject, detailing the proper utilization of company chops and emphasizing the importance of their safeguarding, which is crucial for ensuring legal and financial security.

What is a China Company Chop?

A company chop is a physical stamp or seal bearing a company’s official name. This stamp is an official signature used in various processes such as opening bank accounts, signing contracts, approving transactions, etc. The primary purpose of the company chop is to provide a legally identifiable and verifiable form of authentication for a company’s business transactions.

Why are Company Chops so Important?

Company chops play an important role in business transactions in China. Outside of China, a signature (or signatures) is generally used to validate documents and transactions, but in China, this is done through the chop.

Chinese company chops are used as an authentication tool, ensuring the legality and credibility of documents. They also symbolize a business’s authority and integrity.

Due to the significance and potential implications of using company chops, ensuring their secure storage and handling is essential. There have been cases of misuse and negligent use of chops. Therefore, access should be limited to those authorized by the shareholders or articles of association.

Types of Company Chops

There are various types of company chops used in China; some of the most essential chops for a company include:

The company chop
Finance chop
Legal representative chop
Customs chop
Contract chop
Invoice chop

1. Official Company Chop

The official company chop is required to validate any document needed to conduct business within China. These chops are special government-issued seals (or stamps) registered with the Administration for Market Regulation (AMR) and filed with the Public Security Bureau (PSB), and must be safeguarded by the legal representative(s) only (China Briefing).

Even though signatures can be used to validate documents on behalf of individuals, only stamping a document with the relevant chop makes the document legally binding for a company.

Purpose: This seal can handle internal and external affairs, and in these instances, the company chop represents a company’s official decision (comparable to a signature in the West).
Application: for any official letters the company provides, any supporting documents for relevant authorities, and used to sign contracts and issue official reports to the public.
Attention: This seal must be safeguarded by the legal representative(s) only. Once the company chop is used or chopped on any documents, it implies that the company has confirmed or agreed upon any activities and accepted and is aware of any subsequent risks or consequences attached to those activities. Furthermore, if a document is chopped, the company shall bear all responsibilities for the consequences of using the company chop.

2. Finance Chop

Every company must have a finance chop, which is used for handling any affairs or documents related to financing (e.g., opening a bank account, authenticating financial documents, issuing checks, or performing bank-related transactions). It is generally advised to keep the company and finance chops separate to avoid misuse.

Purpose: This seal is used to handle any financing-related affairs or documents.
Application: This can be used for actions such as opening a bank account, authenticating financial documents, issuing checks, bank- and performing related transactions.
Attention: Keeping the company and finance chop separate is advisable to prevent misuse.

3. Legal Representative Chop

The company’s legal representative holds the legal representative chop and represents the signature of the legal representative in its absence. Because the legal representative has the authority to enter into binding obligations on behalf of the company, when used solely or along with the company chop, it represents an official company decision. This chop is commonly used to issue cheques, approve payment transactions, or sign contracts.

Purpose: mainly used for financial activities, but also represents the signature of the company legal representative in its absence.
Application: commonly used to issue company cheques, approve payment transactions, and withdraw cash from the bank (alternatively used to sign contracts).
Attention: This chop shall be kept by the company legal representative only. It represents an official company decision if it has been used solely or along with the company chop.

4. Customs Chop

The customs chop is used for import or export-related business activities and is generally kept by the employee(s) in charge of managing import and export-related affairs. Without this chop, the company cannot process any imports or exports (per PRC Customs rules on special customs declaration seals).

Purpose: The chop will be used when the company imports or exports goods that must be declared and reported to Chinese customs.
Application: the customs chop shall be used in the port or custom authorization and control area indicated by the company.
Attention: The chop must be kept by the employee(s) in charge of dealing with import and export-related affairs only. Without this chop, the company cannot process imports or exports.

5. Contract Chop

Many companies use a separate document for signing contracts between parties (such as the company and its employees or the company and a third party, such as a client).

Purpose: to sign contracts on behalf of the company. It may represent the company within the scope of the contract and shall bear all rights and obligations from that place.
Application: used for any business-related contract and agreements with third parties.
Attention: This chop grants the person responsible less authority than the company chop, which helps delegate authority. Nevertheless, only the person permitted to use this chop may keep it.

6. Invoice Chop

Purpose: to issue official invoices or tax receipts (fapiao).
Application: chopping an invoice is required to declare a business expense.

7. Other Chop

Various types of chops, including administrative matters, can be employed for internal purposes within a company. For instance, an HR chop may legally validate employee contracts.

8. Electronic Chop

An electronic chop in China is the digital equivalent of a traditional company chop, a seal or stamp used to authenticate documents and manage internal and external business affairs. These electronic chops are legally recognized under China’s Electronic Signature Law and are used for various purposes, including signing contracts and issuing invoices. They are designed to replace physical chops, enabling more efficient and paperless transactions. Creating and using an electronic chop must be associated with an authorized company representative.
