Populated printed circuit board classification narrowed; new entries created altering duty treatment and parts exemption scope. The notification amends Central Excise exemptions by lowering specified duty rates at two serials, excluding populated printed circuit boards from generic 'Parts, components and accessories' exemptions, inserting new entries for populated printed circuit boards with specified classification and duty treatment, and creating a nil rate entry for parts and sub parts used in their manufacture. It also omits certain serials, removes 'and speakers' from another entry, and substitutes the MRO parts exemption with a provision making it subject to conditions specified in the corresponding Customs table entry.
