Anti-dumping duty extension on soda ash to continue pending sunset review or until an earlier specified date. Extension of anti-dumping duty on imports of Soda Ash from Russia and Turkey is effected by inserting a paragraph into the principal notification providing that the duty shall remain in force until conclusion of the sunset review initiated by the Designated Authority or until an earlier specified date, thereby preserving the existing anti-dumping measure during the review period without changing the substantive rate or scope.
