Sole source Justification-redacted.pdf

This is a Non-Competitive Procurement Justification Memorandum for a sole source acquisition under the Simplified Acquisition Threshold (SAT).

The acquisition requires the purchase of a Ross Model DPM-2 Double Planetary Mixer manufactured by Charles Ross & Son Company to replace a current Ross Mixer that requires replacement. The justification for sole source procurement is based on restrictive rights held by Charles Ross & Son Company, which possesses multiple patents pertinent to the functionality of the planetary mixer required by the requesting branch. Specifically, Patent [number redacted] was awarded for an epicyclic mixing system with dual concentric sun shafts. Market research was conducted via internet search to identify comparable Ross Mixer alternatives meeting the exact specifications listed in the quote, and no alternatives were found. The technical certification was signed by a Chemical Engineer on January 26, 2026, and the Contracting Officer approved the sole source solicitation based on the justification provided.
