The application of the interim measures is limited to a maximum period of four months, as short as possible, or, on the decision of the relevant authorities, to a maximum period of six months, at the request of exporters representing a significant percentage of the trade concerned. If, in the course of an investigation, the authorities consider whether a fee below the dumping margin would be sufficient to eliminate the harm, these periods may be six or nine months. For the purposes of paragraph 2, the amounts relating to administrative costs, sales and profits, as well as profits, are based on actual data relating to the production and sale of the similar product during normal commercial transactions of the similar product by the producer-exporter or producer under investigation. If these amounts cannot be determined on this basis, the amounts can be determined on the basis of: Article 5 sets out the conditions for opening investigations. The AD agreement provides that investigations should normally be initiated on the basis of a written request made «by or on behalf» of a domestic industry. This «permanent» requirement is supported by numerical limits to determine whether domestic producers receive sufficient assistance to conclude that the application is submitted by or on behalf of the domestic industry, which warrants an introduction. The AD agreement establishes, in written requests for anti-dumping measures relating to declarations, prejudice and causation, as well as other information relating to the product, industry, importers, exporters and other issues, in written requests for anti-dumping protection, and provides that, in special circumstances, where the authorities soggy without a written request from a domestic industry, they can only conduct if they have sufficient evidence of dumping. , harm and harm. and causality. In order to ensure that worthless investigations do not continue, which could disrupt legitimate trade, Article 5.8 provides for the immediate closure of investigations in cases where the volume of imports is negligible or if the dumping margin is de minimis, and sets numerical thresholds for these findings.
In order to minimize the commercial effect of investigations, Article 5.10 stipulates that investigations must be closed within one year, under no circumstances after the opening of 18 months. For the purposes of paragraph 2, costs are normally calculated on the basis of the registers of the exporter or producer under investigation, provided that these records are consistent with the generally accepted accounting principles of the exporting country and adequately reflect the costs associated with the production and sale of the product concerned.
