Origin determination: non-originating inputs limited to a fixed FOB value threshold and final manufacture within exporting party required. Origin under the MERCOSUR-India preferential rules requires that the CIF value of non-originating and undetermined-origin materials from outside the Signatory Parties does not exceed 40% of the FOB value of the final product and that the final manufacturing process occur within the exporting Signatory Party; valuation is by CIF at importation where provable or by the earliest ascertained price in the processing territory, with a special port-of-destination rule for landlocked countries.
