C.Isha Arrington

C.Isha Arrington serves as a key procurement lead within the Defense Logistics Agency’s Columbus Division #3, responsible for securing mission-critical strategic materials essential to national defense systems. Focused on high-purity nonferrous metals, specialty chemicals, and engineered industrial inputs, Arrington manages complex acquisitions supporting aerospace, electronics, and weapons platforms. Their work ensures the uninterrupted supply of materials vital to advanced manufacturing and defense readiness, aligning directly with the agency’s mandate to safeguard domestic sources of rare and critical inputs. Arrington handles sole-source and competitive procurements under strict technical and security protocols, often requiring compliance with Defense Federal Acquisition Regulation Supplement (DFARS) clauses for controlled materials. Arrington maintains a primary working relationship with ARES Strategic Mining, Inc., a specialized vendor with proven capability in sourcing and refining strategic metals and advanced industrial feedstocks. The partnership reflects a reliance on a single, highly qualified contractor with niche expertise in material purity, traceability, and defense-compliant supply chain controls. This relationship is characterized by long-term technical alignment, rigorous qualification processes, and consistent performance-based contract execution, with limited reliance on broad market competition due to the highly specialized nature of the requirements. Arrington’s procurement portfolio reflects a 100% non-set-aside approach, indicating a deliberate focus on technical capability over socioeconomic classifications. While small business participation is not formally prioritized through 8(a), HUBZone, or SDVOSB set-asides, the agency’s emphasis remains on mission-critical performance, material integrity, and supply chain resilience, which often necessitates selection of the most technically qualified vendor regardless of size or certification. The primary NAICS classification for Arrington’s acquisitions is 541715, reflecting a heavy emphasis on research and development in physical and engineering sciences. This includes advanced material characterization, process development for high-purity metal refining, and engineering validation of specialty chemical formulations. Arrington’s expertise lies in procuring R&D-driven solutions that bridge laboratory-scale innovation with scalable defense production, requiring deep technical understanding of metallurgy, chemical purity standards, and industrial process controls.
