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.

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 environmental engineering services can be performed internationally, many contracts are negotiated and concluded in Hong Kong. Additionally, the nature of consultancy often requires local presence for effective service delivery, which ties the activity to Hong Kong.
