Permission for domestic procurement of restricted items enables SEZ developers to source sand and soil domestically subject to compliance. Supply of sand and soil from the Domestic Tariff Area to SEZ developers or units is treated as export but classified as restricted. BoA historically required prior approval, imposing conditions that items be actually used and environmental and statutory obligations be met. Temporary delegation allowed Development Commissioners to permit such procurement subject to actual use, environmental compliance and post-facto BoA ratification. BoA has now delegated its power to DC to allow DTA supply of sand and soil for construction or infrastructure in SEZs, conditional on actual use and compliance with environmental and statutory obligations.
