Rules and Usages for Trade
ISF has issued rules and usages for international trade in seed for sowing purposes to clarify and standardize contractual relations between buyers and sellers. These rules are reviewed at
regular intervals. The last amendments were adopted by ISF’s General Assembly in June 2012 and the
new version comes into force on 1 Jan 2013.
This version takes into account important changes that have occurred in international trade as a
result of evolution in technology.
Only the latest version of the rules is posted online. Those in force prior to this date are available
on request from the ISF Secretariat.
