Generalized System of Preferences
preferential tariff system
The Generalized System of Preferences, or GSP, is a preferential tariff system which provides tariff reduction on various products. The concept of GSP is distinct from the concept of "most favored nation" (MFN). MFN status ensures equal treatment in the imposition of a tariff where GSP allows for a differential tariff to be imposed on depending upon factors such as a country's development status. Both the rules comes under the purview of the World Trade Organisation (WTO).
GSP provides tariff reductions for the least developed countries.
History
The idea of tariff preferences for developing countries was the subject of considerable discussion within the United Nations Conference on Trade and Development (UNCTAD) in the 1960s. Among other concerns, developing countries claimed that MFN was creating a disincentive for richer countries to reduce and eliminate tariffs and other trade restrictions with enough speed to benefit developing countries.
In 1971, the GATT followed the lead of UNCTAD and enacted two waivers to the MFN that permitted tariff preferences to be granted to developing country goods. Both these waivers were limited in time to ten years. In 1979, the GATT established a permanent exemption to the MFN obligation by way of the enabling clause.
