Cenvat credit eligibility clarified: credit allowed unless inputs or services are used exclusively for exempted goods, services, or trading. Clarification affirms that CENVAT credit is allowable for inputs and input services used in manufacture or in relation to taxable services except where expressly denied, notably when used exclusively for exempted goods or services (including items exempt under the cited notification) or exclusively for trading; capital goods used exclusively for exempted activity are likewise ineligible. Repair and renovation services for factory/offices and Business Auxiliary Services tied to sale (including commission) remain admissible. Special allocation and reversal rules for banking, financial and life insurance services apply per registration. Pre-amendment completed services retain credit eligibility.
