Excise exemption reform: input-linked eligibility and special-rate refunds based on actual value addition for manufacturers. Amendment revises excise exemption for goods manufactured in specified North East states by linking exemption to inputs specified in the Table, substituting a new Table of chapter-wise goods, and permitting manufacturers to apply for a special rate based on actual value addition (minimum 115% of the notified rate) with auditor certification, specified filing timelines, exclusions for certain goods, shortened fixation period, retrospective refund treatment, start-up refund entitlement from commencement of production, and a mechanism to refund any differential where refunds paid are less than duty paid (excluding CENVAT), with administrative timelines for payment.
