About this opportunity
The Defense Logistics Agency (DLA) Aviation - Bearings Division issued Limited/Sole Source Justification Notice SPE4A6-25-R-XG55 for the acquisition of 65 units of GAGE differential parts (NSN 6685-01-573-0355) from Thuemlin Industrial Products Inc. under a 5-year base period contract. The sole source justification was approved under 10 U.S.C. 3204(a)(1) based on the determination that technical data is not economically available and this represents a second or subsequent direct purchase from the manufacturer, preventing full and open competition despite the material being classified as commercial off-the-shelf (COTS). A sources sought notice posted in August 2025 yielded no responses from alternative vendors, and market research confirmed that additional manufacturing sources could not be identified. The contract SPE4A6-26-D-C057 was awarded to Thuemlin Industrial Products Inc. on March 25, 2026, with an approval authority ceiling of $750,000 and no optional periods included in the award.
