Duty exemption for cottage match units grants reduced excise rates for first clearances subject to production and membership conditions. Concessional excise duty applies to matches manufactured without the aid of power by cottage and tiny units, limiting duty on first clearances subject to annual and monthly production and clearance caps, eligibility restricted to members of registered co-operative societies or manufacturers recognised by KVIC or State KVIBs, exclusions where higher-duty labels of other manufacturers are used, and specific adjustments for bamboo splints and pack sizes, with prior concessional clearances aggregated for threshold computation.
