I am planning to start a e-comm website which sells women garments. I have few queries on how to start the operation.

I am planning initially to ship products directly from foreign country like (India, china) to customers in USA/Europe.

The queries I have for the above are.

1) What custom duties I or the customer has to pay when they receive the product.

2) Do I have to register a company in USA/Europe to support it.

3) Will I have to file taxes in in USA/Europe for the products i sell in these areas.

4) Will I be able to host and register a domain/website in USA and operate from a foreigh country without any liabilities in USA.

Please someone help me or guide me to get correct legal information on the above queries.

Thanks in advance
