(35 ILCS 105/3-10)

Sec. 3-10. Rate of tax. Unless otherwise provided in this Section, the tax imposed by this Act is at the rate of 6.25% of either the selling price or the fair market value, if any, of the tangible personal property. In all cases where property functionally used or consumed is the same as the property that was purchased at retail, then the tax is imposed on the selling price of the property. In all cases where property functionally used or consumed is a by-product or waste product that has been refined, manufactured, or produced from property purchased at retail, then the tax is imposed on the lower of the fair market value, if any, of the specific property so used in this State or on the selling price of the property purchased at retail. For purposes of this Section "fair market value" means the price at which property would change hands between a willing buyer and a willing seller, neither being under any compulsion to buy or sell and both having reasonable knowledge of the relevant facts. The fair market value shall be established by Illinois sales by the taxpayer of the same property as that functionally used or consumed, or if there are no such sales by the taxpayer, then comparable sales or purchases of property of like kind and character in Illinois.
