IEC or Import-Export Code is required for businesses who intend to either import any raw material or capital goods from outside the territory or India or who wishes to export their finished goods out of India. In Case of Service Providers, IEC is mandatory only if it wishes to avail the benefits under foreign trade policy.
Earlier the IEC no. used to be a Numerical Code. But after the Implementation of GST Act in India, IEC no. is same as the PAN of the Firm. Although Import-Export Code Certificate is still separately issued by DGFT which comes with lifetime validity unless surrendered or revoked. IEC doesn’t have any monthly or annually filing requirements with the department unlike GST and other acts.
