Valuation of job worked goods: transaction value governs when principal sells at removal; otherwise normal value or other rules apply. Where excisable goods are produced by a job worker for a principal manufacturer, if the principal sells the goods at removal to an unrelated buyer for a price that is the sole consideration, value is the transaction value of that sale; if goods are transferred elsewhere and sold from that other place to an unrelated buyer for price as sole consideration, value is the normal transaction value of such sales at or about the same time or nearest thereto; otherwise existing valuation rules apply mutatis mutandis. Transportation cost from the selling premises to place of delivery is excluded from value. 'Job worker' is defined as a person manufacturing goods on behalf of a principal from inputs supplied by the principal or an authorised person.
