Within the specifications Section “Solicitation Provisions” pages B‐9/B‐10, the Government references FAR 52.225‐9 and FAR 52.225‐11. These are significantly different FAR’s in that “‐9” only allows for the supply of US materials and “‐11” allows for the supply of US and other countries we have fair trade agreements with.
