Section 9

While the Agency will not, as a general rule, claim exemption from excise duties and from taxes on the sale of movable and immovable property which form part of the price to be paid, nevertheless when the Agency is making important purchases for official use of property on which such duties and taxes have been charged or are chargeable, States parties to this Agreement will, whenever possible, make appropriate administrative arrangements for the remission or return of the amount of duty or tax.
