This site has been developed in-house, jointly by Iftekhar Ahmed and Santanu Acharya, Preventive Officers of Indian Customs, Calcutta. However, without the active interest, guidance, persistence and contribution of Shri A. K. Raha, Commissioner of Customs, Calcutta, it would have been impossible to commence this project, let alone bring it to a successful conclusion. Although the construction of this site has been an attempt by amateurs with no professional experience in this field, every effort has been made to provide factually correct information and make the site error-free. Please read the disclaimer statement in this regard. Following is a list of officers and staff of Calcutta Customs who have actively contributed to the construction of this website.
