The NANO 4 RFP was issued on March 4, 2024, and the original solicitation (as revised) remains open throughout the ordering period through the use of innovative provisions as prescribed in Section 2, Clause 2.9, IDIQ CLIN Pool Opt-in, and Clause 2.9.2, IDIQ CLIN Pool Opt-in After Award. The NANO 4 contract’s ordering period remains valid through June 30, 2029. The RFP resulted in the award of six indefinite delivery (ID) fixed price with Economic Price Adjustment (FPEPA) requirements contracts with fixed price delivery orders for the supply of liquid nitrogen and liquid oxygen in support of operations at agency centers and facilities across the United States. NASA made award to the following companies: Air Products and Chemicals, Inc., Airgas USA LLC (Central), Airgas USA LLC (South), Linde, Inc., Nippon Sanso Matheson, Inc.
