Part 7: Implementation of international obligations Section 90: Treaty state suppliers: non-discrimination
Subsection (1) prohibits a contracting authority from discriminating against a treaty state supplier when it carries out a procurement.
	Subsection (2) explains the meaning of discrimination against a treaty state supplier. It is discrimination if the contracting authority treats a treaty state supplier less favourably than it would a UK supplier, due to the supplier’s association with its treaty state or lack of association with the UK or another treaty state.
	Subsection (3) clarifies that the test of discrimination is whether there is a material difference in treatment between a UK supplier and treaty state supplier.
	Subsection (4) clarifies that a supplier has an association with a state (being the concept used in subsection (2)) where that state is the place of origin of the goods, services or works being supplied by that supplier.
	Subsection (5) defines a "treaty state". It is a state, territory or group of states or territories that is party to an international agreement specified in Schedule 9 (treaty state suppliers (specified international agreements)).
	Subsection (6) clarifies that in respect of subsection (2)(a) a treaty state is a supplier’s treaty state if the supplier is entitled to the benefits of such an international agreement by virtue of that treaty state being a party to the agreement.
	Subsection (7) defines "United Kingdom supplier", which includes suppliers from the British Overseas Territories and the Crown Dependencies.
