Why 6 digits?
HSIC subclasses are 6 digits. The first four match the international ISIC class; Hong Kong adds a two-digit local suffix for finer detail, especially across its import and export trade, so a code steps from a 4-digit class straight to a 6-digit subclass. More on the HSIC structure.
This subclass covers a variety of construction installation and maintenance activities that are not classified elsewhere. It includes the installation and maintenance of items such as automated and revolving doors, lightning conductors, and thermal, sound, or vibration insulation.
This classification includes
- automated and revolving doors, installation and maintenance
- lightning conductors, installation and maintenance
- thermal, sound or vibration insulation, installation and maintenance
- miscellaneous construction installation and maintenance, n.e.c.
Licences and approvals
What this activity needs to operate
No sector-specific licence applies to this activity. It can be set up as a standard Hong Kong company without extra regulatory approvals. Premises-based or product-based permits can still apply case by case; Emerhub confirms the exact position during scoping.
Offshore profits claim feasibility
MediumWhile some installation and maintenance services can be performed offshore, many activities require physical presence in Hong Kong for compliance and customer interaction. Contracts are often negotiated locally, which ties the business to the Hong Kong market.
