SIN: 00CORP-500 Order-Level Materials (OLMs) - OLMs are supplies and/or services acquired in direct support of an individual task or delivery order placed against a Federal Supply Schedule (FSS) contract or FSS blanket purchase agreement (BPA). OLMs are not defined, priced, or awarded at the FSS contract level. They are unknown before a task or delivery order is placed against the FSS contract or FSS BPA. OLMs include direct materials, subcontracts for supplies and incidental services for which there is not a labor category specified in the FSS contract, other direct costs (separate from those under ODC SINs), and indirect costs. OLMs are purchased under the authority of the FSS Program and are not "open market items."


  • OLMs are only authorized for inclusion at the order level under a Time-and-Materials (T&M) or Labor-Hour (LH) Contract Line Item Number (CLIN) and are subject to a Not To Exceed (NTE) ceiling price.
  • The OLM SIN is only authorized for use in direct support of another awarded SIN.
  • Prices for items provided under the OLM SIN must be inclusive of the Industrial Funding Fee (IFF).
  • The value of OLMs in a task or delivery order, or the cumulative value of OLMs in orders against a BPA awarded under an FSS contract, cannot exceed 33.33%.
