Safeguard measure review: Director General may recommend continuation, withdrawal or modification based on injury and industry adjustment. The Director General must periodically review the continued imposition of a safeguard measure and recommend to the Central Government either continuation-if necessary to prevent or remedy serious injury with evidence of industry adjustment-or withdrawal where unjustified. For measures imposed beyond three years a mid term review must consider withdrawal or liberalisation. The Director General may review tariff rate quota usage for modification. Reviews must conclude within eight months from initiation, subject to possible extension, and specified procedural rules apply mutatis mutandis.
