Iran has recently moved toward more trade liberalization in order to comply its trade regulations by international ones. Removing non-tariff barriers (NTBs) and replacing by tariff equivalents (so called tariffication) is clearly emphasized in articles 115 and 33 of the third and fourth five years cultural, economic and social development plans respectively. In this paper different procedures on NTBs quantification are fairly compared and applied for agriculture sector. The main findings show that tariff equivalents of non-tariff measures applied for meat products, grains, some vegetables and pulses had positive sign in whole period under studying(1997-2003). Meanwhile the respected values for some horticultural products, dairy, egg and honey were negative.
