The primary aspect of the boycott prohibits the importation of Israeli-origin goods and services into
boycotting countries. The secondary and tertiary aspects of the boycott discriminate against U.S. and
other foreign firms that do business with both Israel and boycotting countries and directly affect U.S.
exports to the region. The secondary boycott prohibits any entity in Arab League members from
engaging in business with U.S. or other foreign firms that contribute to Israel’s military or economic
development. The tertiary boycott prohibits business dealings with U.S. and other firms that do business
with blacklisted companies. Such firms are placed on a blacklist maintained by the Damascus-based
Central Boycott Office (CBO), a specialized bureau of the Arab League.
