Customs exemption amendments expand eligible manufacturing machinery and inputs, modifying the tariff schedule under statutory powers. Amendment to notification No. 25/2002-Customs under section 25(1) revises the exemption table by substituting the S. No. 25 entry to specify CD/CD-R/DVD replication/manufacturing lines and equipment; adding components (switches, tape deck mechanisms, DC micromotors, loudspeakers) to S. Nos. 30, 33 and 38; substituting S. No. 34 to list CNC wire cut machines and electronic components; and inserting new serials 61-67 identifying specific machinery (testers, magnetisers, ultrasonic welding, fuse assembly and testing machines, masking and PCB equipment, insert moulding and 3D measuring systems) together with the consumables and assemblies eligible for exemption.
