Port registration is a crucial step for exporters to start shipping goods from India. After obtaining an IEC (Importer Exporter Code), exporters need to register at their chosen port or airport through a CHA (Customs House Agent). This process, known as AD Code or port registration, ensures smooth clearance of shipments and enables exporters to claim export benefits. Registration involves submitting the AD Code letter issued by your bank, along with relevant documents, to customs at the designated port. Once approved, your company is linked with the port, allowing you to export goods legally and efficiently.
