Should the Community consider that a textile product covered by this Agreement is being imported into the Community from Bulgaria at a price abnormally lower than the normal competitive level and is for this reason causing or threatening to cause serious injury to Community producers of like or directly competing products, it may request consultations with Bulgaria, and in that event the following specific provisions shall be applicable. 2. Consultations shall be held at the request of the Community in order to ascertain whether the situation described in paragraph 1 exists. If agreement is reached as to the existence of such a situation, Bulgaria shall take the necessary steps to remedy it. 3. If the consultations referred to above fail to produce agreement within 30 days of the Community's request forsuch consultations, and should consignments of the product in question continue to be sent at prices which are lower than the range of prices charged under normal conditions of competition, and for this reason cause or threaten to cause serious injury to the Community producers referred toin paragraph 1, the Community, while continuing consultations with a view to reaching a mutually acceptable solution, may refuse to import the said consignments. Such action may be continued only for as long as is strictly necessary to prevent or remedy the situation. 4. In critical circumstances, where imports of specific textile products at prices below the range of prices charged under normal conditions of competition could cause injury which it would be difficult to repair, the Community may temporarily refuse to import the said products pending agreement on a solution in the course of consultations. Such consultations shall be opened without delay, and in any case within five days of the request by the Community, with a view to reaching a mutually acceptable solution. The two Parties shall do their utmost to reach a mutually acceptable solution within five days of the opening of such consultations. 5. For the purposes of applying the provisions of this Article, in order to determine whether the price of a textile product is 'below the range of prices charged under normal conditions of competition', it may be compared with: - the prices of like products at a comparable marketing stage on the market of the importing country, and- the prices generally charged for such products sold under normal market conditions by other exporting countries on the market of the importing country, and- the lowest prices charged for such products sold under normal market conditions by any other exporting country in the three months preceding the request for consultations, and not having led to the adoption of any measure by the Community. 6. Bulgaria may request consultations at any time with a view to examining such difficulties as may arise from the application of the provisions of this Article.
