SSI exemption and CENVAT credit may be claimed concurrently, subject to separate accounting and refund or adjustment mechanisms. Units availing SSI exemption for home consumption may nevertheless claim Modvat/CENVAT credit for inputs used in export production (clearances under bond or on payment of duty). Such credit can be utilised to pay duty on similar goods cleared for home consumption once the exemption threshold is exceeded, or refunded where adjustment is not possible, subject to maintenance of separate accounts tracing inputs and production for export and home consumption and compliance with Modvat/CENVAT refund procedures.
