ANDREW S. MCCREATH & SON, INC.

ANDREW S. MCCREATH & SON, INC. delivers specialized professional services in the field of advanced materials analysis and sampling, with a demonstrated focus on high-purity metallic substances for defense applications. Their core capability centers on the technical execution of bulk electrolytic manganese metal (EMM) sampling protocols, requiring precise handling, analytical characterization, and compliance with stringent military-grade quality standards. This work demands expertise in metallurgical sampling techniques, laboratory chain-of-custody procedures, and the application of electrochemical and spectroscopic methods to ensure material integrity and purity verification. The contractor’s specialization lies in supporting mission-critical material supply chains where trace impurity control and batch consistency are essential to performance in defense systems, positioning them as a niche provider in materials assurance services. The company has performed work for the Department of Defense, specifically in support of defense material logistics and quality control initiatives involving high-performance metallic components. Their engagement reflects a targeted, technical support role rather than broad systems integration, indicating a relationship built on precision service delivery for specialized material testing needs within the defense industrial base. The primary NAICS classification—541990, All Other Professional, Scientific, and Technical Services—reflects a focused operational model centered on non-standardized, highly specialized technical services that fall outside traditional engineering or scientific categories. This contractor operates at the intersection of materials science and defense procurement, serving a narrow but critical vertical within the broader defense supply chain. As a small business structured as a 2L entity based in Harrisburg, Pennsylvania, the company maintains a lean, specialized workforce without formal government certifications. Their geographic presence is regional, yet their technical services are aligned with national defense priorities, allowing them to serve federal requirements through targeted, high-value contracts requiring deep domain expertise rather than large-scale infrastructure.
