The process itself can be long drawn, tedious, complex and demanding on the resources and capacity of LDCs. These commitments also tend to exceed those required of LDCs and other developing countries that joined the organisation in its early years (Table 7.4). Similar differences between original LDC members and recently acceded LDCs exist in the level of binding coverage, i.e. the percentage of tariff lines that members agree to bind at a certain level upon joining the organisation. While the WTO Agreement on Agriculture requires all members to bind all agricultural tariff lines, the level of binding coverage in industrial goods varies considerably among the LDCs.
