Does a Proprietor doing export require Professional tax ID and & its certificate ID or not ?

The condition for Paying a professional tax is very vaguely defined and what I understood is :-

According to rules for getting a registration for professional tax is :

1. you should be an employee so your employer will pay on behalf of you or
2. you should be earning from professional services requires practice such as chartered accountant, company secretary, lawyer, doctor

but I will be not providing any service involving a practice license, I will be only doing an export business as a proprietor such as

1. buying finished goods from suppliers and then adding my margin and then selling it to other countries
2. buying semi-finished goods and adding some artwork (handicraft item) and then after adding my margin selling it to other countries
3. or giving consulting services on my one (not hiring any employee), consulting could be on software development, or project management.

All the above three situations do not involve any employee (I will be not hiring any employee) or do not involve any practicing license.
