In Chittagong CEPZ Customs, approximately 5,000–7,000 import and export documents are processed every day. It is commonly reported that a minimum of BDT 500 in unofficial “tips” is expected per document for customs-related services, and without such payment, documents may face delays or services may not be provided. Based on an average of 6,000 documents per day: 6,000 × BDT 500 = BDT 3,000,000 per day Therefore, the estimated daily amount would be approximately BDT 30 lakh (3 million). This is just one example from a single office scenario.
