Hong Kong Company Chop: Practical Guidance for Businesses

Written by Ascentium Content Team | 04 January 2026

What is a Hong Kong Company Chop?

In Hong Kong, a company chop, sometimes called a company stamp or seal, is still widely used in day-to-day corporate operations.

The Companies Ordinance no longer requires companies to maintain a chop, but many organisations continue to use one to signal company authorisation on documents such as:

  • Contracts
  • Board resolutions
  • Corporate declarations
  • Administrative filings

For businesses operating across jurisdictions, especially those interacting with the Chinese Mainland, company chops remain a familiar and expected part of business practice.

Common Types of Company Chops

Most Hong Kong companies use one of two standard formats.

Although neither format is legally required, banks, counterparties and government authorities may still expect a chop on paper documents.

Circular Chop

The circular chop is the most common format.

It typically includes:

  • The company’s full registered name (English, Chinese or both)
  • A circular layout around the stamp edge
  • Optional details such as the company registration number or a central emblem

This chop is often used for general corporate documentation and administrative purposes.

Rectangular Chop

The rectangular chop is commonly used when executing agreements.

It usually contains the phrase: “For and on behalf of [Company Name]”

Space is left below for an authorised signatory.

This format is practical when a signature and chop are used together to formalise execution of contracts or declarations.

Governance and Control of Company Chops

Because a company chop signals company authorisation, it should be treated as a controlled corporate instrument.

Good governance practices typically include:

  • Restricting access to authorised personnel
  • Maintaining clear internal protocols for chop use
  • Keeping secure storage records
  • Ensuring documentation of when and how the chop is used

Unauthorised or improper stamping can expose a company to legal, operational or reputational risk.

Clear governance helps ensure that chops are used appropriately and consistently.
