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 activity involves the drilling of water wells to access groundwater resources. It includes the construction and installation of wells for the extraction of water for various uses, such as agricultural, industrial, and domestic purposes.

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
MediumWater well drilling services are often performed on-site, which ties the activity to Hong Kong premises. Contracts may be negotiated offshore, but the physical nature of the work typically requires local presence and resources, limiting the potential for offshore tax treatment.
