Pure agent exclusion: costs paid as a pure agent are excluded from taxable service value when prescribed conditions are met. Rule 8 provides two valuation rules: a pure agent exclusion where costs incurred by a service provider acting as pure agent are excluded from taxable service value if eight conditions and the four part definition of pure agent are satisfied; and a money changer valuation rule where value for currency exchange involving Indian Rupees is the difference between transaction rate and RBI reference rate multiplied by units exchanged, with specified fallback percentage measures when RBI rates are unavailable or neither currency is rupee.
