All references in the Customs Act to Industrial Development Zones (IDZ), will be replaced with Special Economic Zones (SEZ) once the  new Special Economic Zones Act, 2014 (SEZ Act) comes into effect (date unknown). When the SEZ Act comes into operation, existing IDZ operators and Customs Controlled Area (CCA) enterprises registrations will not be effected. However, existing registrants will need to enhance their existing processes, procedures to align themselves with the SEZ Act requirements. The SEZ Act will replace the existing IDZ provisions in the Manufacturing Development Act, 1993. IDZs will in the future be one of the SEZ categories, alongside free ports, free trade zones and sector development zones.
