Intent to avail exemption: manufacturers must notify excise authorities and supply specified particulars before claiming concession. Manufacturers intending to avail an exemption notification must notify the Deputy or Assistant Commissioner of Central Excise of their intent and provide the manufacturer's name and address, the excisable goods produced, and the nature and description of imported goods used in manufacture; unregistered manufacturers must first obtain registration under the Central Excise rules before furnishing these particulars.
