Explanation:

Both statements are incorrect.

Recently, the Department of Posts, Government of India (India Post) and United States Postal Service signed an agreement for electronic exchange of customs data related to postal shipments between the two countries. 

• The primary objective of this agreement is to facilitate ‘ease of exports’ for small and large exporters through postal channels from different parts of the country.
• The agreement will make it possible to transmit and receive electronic data of international postal items prior to their physical arrival at the destination and would enable customs clearance of postal items in advance in line with the evolving global postal framework.
• However, there is no provision of custom duty free trade. 

Hence option 4th is correct.
