Concern about the use if technical barriers as restrictions to trade has increased since the World Trade Organization Agreement on Agriculture. In this analysis, we quantify the phytosanitary barriers to U.S. apple exports to Japan by calculating tariff-rate equivalents. We examine the trade and welfare impacts of removing phytosanitary barriers and tariffs under two assumptions regarding transmission of the bacterial disease fire blight: first, that transmission via commercial fruit is not possible, and second, that it can occur. The disease losses required to eliminate the grains to trade are estimated to be much larger than those experienced in other countries.
