Approval procedure for ICD/CFS/AFS governs application, LOI issuance, validity and grounds for suspension or revocation. Application for setting up ICD/CFS/AFS requires submission of an application with a Detailed Project Report to Member (Customs), CBIC and an advance copy to the jurisdictional Commissioner, who must examine feasibility and provide categorical recommendations; the IMC then reviews comments and independently approves or refuses projects. On approval, a Letter of Intent is issued with limited validity and extensions; IMC may suspend or revoke approval for breach of conditions, public interest prejudice, or conviction of promoters.
