This free writing prospectus relates only to the initial public offering of common units representing limited partner interests of OCI Resources LP and should be read together with the preliminary prospectus dated September 3, 2013 relating to this offering (the “ Preliminary Prospectus ”), included in Amendment No. 4 to the Registration Statement on Form S-1 (File No. 333-189838) (the “ Registration Statement ”) relating to such securities. On September 10, 2013, we filed Amendment No. 5 to the Registration Statement reflecting substantially the same changes as are included in this free writing prospectus.
