Article 25
Where compliance with the provisions of Article 17(3) leads to: (i) re-export towards a third country against which the exporting party maintains, for the product concerned, quantitative export restrictions, export duties, or measures having equivalent effect, or (ii) a serious shortage, or threat thereof, of a product essential to the exporting party; and where the situations referred to above give rise, or are likely to give rise, to major difficulties for the exporting Party, that Party may take appropriate measures under the conditions and in accordance with the procedures laid down in Article 26. The measures shall be non-discriminatory and shall be abolished when conditions no longer justify their maintenance.
