Most nations have adopted the nation`s most preferred principle when setting tariffs, which has largely replaced quotas. Tariffs (preferably quotas, but still an obstacle to trade) have in turn been constantly reduced in successive rounds of negotiations. Typically, AE surveys calculate different dumping margins, even for different companies in the same country. When applying AD duties, these different companies will apply separate tariffs for their products. Therefore, the measure is highly discriminatory and would normally be contrary to the treatment of the MFN. The increase in tariffs would also increase it above the tariff rate imposed by the country in the last round of negotiations. However, Section 6 of the original GATT authorizes this exemption. Notwithstanding Article I of the general agreement, the parties can give developing countries more differentiated and favourable treatment without giving such treatment to other parties. Governments give a degree of control to an international agreement from scratch in these provisions affecting the rights of the contracting parties under the general agreement. A member informed the General Council that the import restrictive measures adopted for balance-of-payments purposes had been amended or amended, as well as any changes to the time frames for the lifting of the measures announced in paragraph 1. Substantial changes are communicated to the General Council before or no later than 30 days after they are announced.
Each member makes a consolidated notification to the secretariat each year, including any changes to legislation, regulations, declarations of principle or public notices, for consideration by members. Communications include, where possible, comprehensive information at the tariff lines on the nature of the measures applied, the criteria used for their management, product coverage and trade flows. In determining which members have the primary interest of a supplier (whether in paragraph 1 or Article XXVIII, paragraph 1) or in a substantial interest, only the trade of the product concerned, which took place on the basis of the MFN, is taken into account.
