Bid securing declaration is supposed to be used for all procurement whose value does not exceed the thresholds for exclusive preference and where local firms have been invited. For example, for all procurement for works with values less or equal to Tshs 10 billion; goods with values less or equal to TShs 2 billion and non-consultancy services with values less or equal to Tshs 2 billion. When the value of procurement is above the threshold for exclusive preference or when the national and international competition involves foreign bidders, tender security shall be required.
