Duty Assurance is customs compliance software for Indian importers, exporters and customs brokers (CHAs). It checks every Bill of Entry and Shipping Bill against official CBIC and DGFT data before you pay or file: HSN code classification, basic customs duty, Social Welfare Surcharge, IGST, exemption notifications, CBIC exchange rates, anti-dumping, countervailing and safeguard duties, and India's free trade agreements (India-Japan CEPA, ASEAN, Korea, UAE, Australia, UK and more). On exports it checks duty drawback and RoDTEP so nothing is under-claimed. It also tracks Advance Authorisation, EPCG licences, bonds and scrips with expiry alerts, and gives management a dashboard of duty paid, savings found and errors caught. Every finding shows its official source. Start with a free check of 10 past filings.
