Company chops, seals and signatures in China.

Company chops are among the most consequential documents a foreign business will manage in China. Unlike in most Western jurisdictions where a signature is the primary instrument of legal authorisation, the company chop in China carries equivalent or greater legal weight and binds the entire company regardless of who applies it. Understanding how chops work, what types exist and how to manage them correctly is necessary for any foreign-invested enterprise.

This guide covers what company chops are, how they compare to signatures, the different types in use, how to use them correctly and what to do if something goes wrong.

What is a company chop and signature in China?

A company chop, also referred to as a company seal or stamp, is a physical tool used to authenticate documents in China. The official company chop is typically circular or oval in red ink, bearing the company’s Chinese registered name. It carries legal effect and is treated as the company’s authorisation.

A signature in China is a personal mark used to indicate an individual’s agreement or authorisation. While electronic signatures are legally recognised in China under the Electronic Signature Law and are increasingly used for B2B contracts, the physical company chop remains the standard for most commercial and government transactions.

Key differences between a company chop and a signature

Both company chop and signature operate differently in the Chinese business context and carry different levels of risk for the company.

The key practical implication of this distinction is liability. The company remains legally bound by documents stamped with its chop even if the person who applied it lacked proper internal authority, unless the counterpart was aware of that limitation. This makes chop access control a governance matter.

Types of company chops in China

Companies in China typically use six types of chops, each with a specific function. Using the wrong chop may invalidate a document or create compliance issues.

• Official company chop: The primary chop for official documents, contracts, letters, certificates and introduction letters. It is circular or oval, uses red ink and includes the company’s Chinese registered name.
• Legal representative chop: A personal name chop linked to the legal representative, typically rectangular and used primarily for banking purposes to represent the will of the legal representative.
• Financial chop: Used for banking operations, including issuing cheques and verifying financial documents.
• Contract chop: An optional seal for signing contracts with employees and forming binding agreements with clients and suppliers. It is often used to delegate signing authority without granting access to the official company chop.
• Invoice (fapiao) chop: A mandatory chop for stamping invoices and tax receipts. While invoicing is increasingly digital, this chop remains relevant for paper fapiao.
• Customs chop: Required for cross-border trade activities, used for import and export declarations and is mandatory for all customs-related documentation.

All chops must be produced by an authorised maker and registered with the public security bureau after the business licence is issued. As they are required for banking, contracting and regulatory interactions, companies should obtain all relevant chops before commencing operations.

How to use and validate a company chop in China

Using a company chop correctly and being able to assess the validity of a counterparty’s chop are two important skills for foreign businesses operating in China.

How to use a company chop correctly

Each chop is used only for its designated purpose. Validity also depends on the physical characteristics. The official company chop is applied in red ink in a circular shape, and the name on the chop must match the Chinese registered name of the company.

For significant documents, it is good practice to require a senior executive’s signature alongside the chop. Maintaining a chop usage log, recording the document type, date, purpose and the use, creates an audit trail and helps detect misuse.

Validating a counterparty’s chop

When receiving documents from Chinese counterparties, the chop should be checked for the same physical characteristics. Any deviation should be reviewed before the document is accepted as valid.

For higher-value transactions, a counterparty’s chop can be validated by cross-checking the chop against public security bureau records or verifying company details on State Administration for Market Regulation (SAMR) national enterprise information platforms.

Electronic seals are increasingly used in China and carry the same legal validity as physical chops if properly registered. If a counterparty presents an electronic seal, confirming its registration is the equivalent of physical chop validation.

What happens if a company chop is lost or stolen

Loss or theft of a company chop creates immediate risk of unauthorised contracts, fraudulent transactions or misuse by former employees or third parties and requires prompt action.

The steps to take are:

• Report to public security authorities immediately:File a report with the local public security bureau as soon as the loss or theft is discovered. This creates an official record and helps protect the company against misuse.
• Notify key counterparties:Inform banks, major suppliers, clients and other regular counterparties to reduce the risk of fraudulent documents being accepted.
• Apply for a replacement chop: Obtaina replacement through the same government-authorised process as the original. The original chop registration will be cancelled and a new one is issued.
• Conduct a document audit: Review recent stamped documents to identify any unauthorised use between the time of loss and the report being filed.

Operating without a valid registered chop can disrupt banking and contract signing, so the replacement process should be initiated immediately.

Managing and protecting your company chop

Because the chop represents the company, its management requires formal controls. The following practices reduce the risk of misuse and strengthen corporate governance.

• Limit access strictly: Restrict access to authorised personnel only, with the official company chop held by a small number of trusted individuals. Some companies outsource custody to a third-party provider to ensure neutral, auditable control.
• Maintain a chop usage log:Record every use, including the document type, date, purpose and the user. This creates an audit trail and helps detect misuse early.
• Minimise the number of chops in circulation: Maintain only one of each mandatory chop. Create additional chops, such as a contract chop, only where operationally necessary.
• Require a senior countersignature:For significant documents, require a senior executive to sign alongside the chop.
• Conduct regular document audits:Periodically review stamped documents to identify any unauthorised use.

How to manage chops when a key person leaves

When a legal representative or senior employee with chop access leaves, chop management should be reviewed immediately as part of offboarding. All chops held by or accessible to them should be retrieved and access revoked before or at departure. If the departing individual is the legal representative, the change is registered with SAMR and the legal representative chop reissued in the name of the new appointee.

A former employee retaining a company chop, particularly in a contentious exit, creates a serious risk, including exposure to unauthorised contracts and financial liability that is difficult to unwind.

Conclusion

Company chops are a foundational element of doing business in China, carrying legal weight that goes well beyond what most foreign businesses are accustomed to. Managing them correctly is a core part of corporate governance for any foreign-invested enterprise. This means knowing which chop applies to which document, controlling who has access and responding promptly when something goes wrong. As China’s regulatory environment continues to evolve, including the growing recognition of electronic seals, staying current with chop-related requirements remains an ongoing responsibility.
