Customs exemption for metro equipment requires certificate confirming procurement for the metro project and final ownership. The amendment inserts an exemption entry for all equipment, machinery and rolling stock procured by or on behalf of the Delhi Metro Rail Corporation Ltd. for use in the Delhi MRTS Project, exempting such goods from customs duty; it also adds Condition 92 requiring, at importation, a certificate from the Chairman or Managing Director of the Corporation certifying procurement for the project, inclusion in the Corporation's inventory, and final ownership by the Corporation.
