What is a Green Box (Company Kit)?

In Hong Kong, once you have completed company incorporation (CI) and business registration (BR), a Green Box will usually be given. As the name suggests, a Company Kit is a dark green box with the name of the company shown on one side. Inside the Box, there are several kinds of legal document indicating a company’s business information, and items proving the legitimacy of the corporation.

What is inside a Company Kit? 

The contents of a Company Kit may vary depending on the application method and choice of service provider, but generally speaking, a Green Box consists of the following:

  • Company Signature Chop
  • Company Round Chop
  • Common Seal
  • Articles of Association
  • Statutory Book
  • Share Certificates
  • Board Minutes Book


What is a Company Kit used for?

Company Signature Chop

The Company Signature Chop is also known as the financial seal or rectangle seal. It is best for signing contracts, bills, internal company documents, etc. The Chop is designed with a space for signature, thus it must be signed by an authorized person in order to be legally valid. The colour is commonly blue or purple.

Company Round Chop

Company Round Chop can also be known as the amendment chop. There are two inner rings in the circle, with the company’s English name and an asterisk sign shown on the outer one. The Round Chop is usually purple or atomic blue. You can stamp it beside a correction on paper for acknowledgement, or to sign off a parcel, but not to confirm contracts.

Common Seal

The Common Seal is made of metal. It is usually round in shape, engraved with the company name to be later embossed on a sticker, which is then affixed to documents. The seal allows the authorized person to sign on behalf of the company and is often used for important documents such as legal deeds. However, since 2014, the Companies Ordinance has allowed Hong Kong companies to opt out of the use of the Seal, so it has rarely been used in recent years.

Articles of Association

Articles of Association (AA) is crucial to the establishment of a company. It could be useful when applying for a corporate bank account. AA states the details on the responsibilities of the members of the company, the share capital of the enterprise, and the terms and conditions of the organization.

Business Registration Certificate (BR), Certificate of Incorporation (CI)

The two certificates are proofs of the incorporation of a company. They are mainly used as the supporting documents for tax return, bank account opening, and audit report, etc.

Statutory Book

For recording information and registers of directors, shareholders, company secretaries and for keeping minutes of directors' meetings, minutes of shareholders' meetings, statutory forms, etc.

Share Certificates

Share certificates shall be used as a certificate of transfer, purchase or sale of shares in a company.

Board Minutes Book

Where minutes of meetings of the directors are kept.


Is Company Kit necessary?

In the digital age, the need for a physical Green Box is decreasing as many documents can be stored in electronic form. However, the Company Kit still embodies the milestone in the formation of a company and its contents are valued for communicating with external parties, such as the process of opening bank accounts, loan application, issuing invoices and signing legal documents. In addition, it is better to keep the company chops physically in the Kit.
