If your friends and relatives are in foreign countries then you should guide them in a proper way if they have got no idea about export import.
90% of regulations & formalities remains the same but..... you should.....
1. Ask them to visit CA (Chartered accountant) to open a Export Import Firm
2. Ask them to visit CHA (Custom House Agent) or CNF (Clearing and Forwarding Agent) & do import port registration
3. Ask them to visit the official department of customs (Find from Google & call them)
4. Kindly do check the import duty in their countries via http://www.macmap.org/
5. Is there any Free trade agreement with India? If they have they will enjoy less duty or duty-free imports for it check rules of origin via http://findrulesoforigin.org
& if you want to export them some small goods then you can send it via courier, in most countries courier imports do not need any firm or registration for customs clearance.
