Customs duty exemptions conditioned on specified certifications and undertakings to secure concessional import treatment for targeted sectors. The notification grants concessional customs duty or exemption subject to specified eligibility, prescribed documentary certifications from designated authorities, adherence to procedural rules, and furnishing of undertakings or bonds restricting use, sale or disposal. It applies sectorally to agriculture, health, pharmaceuticals, defence, telecommunications, power, petroleum, export oriented manufactures and cultural/educational imports. Non compliance generally triggers payment of the difference between duty that would have been payable but for the exemption and the duty paid at importation, and may require post import production of certified accounts or re exportation.
