Overview
In federal procurement
R425 is the federal PSC for professional engineering and technical services: specialized technical support, assessments, and engineering advisory. Agencies use it for technical-services contracts that are advisory or engineering in nature rather than a software build or hardware buy. It maps to NAICS 541330 and 541690-class work and is filed in ITC’s SAM PSC assertions.

The same capability, commercially
Commercially, R425 is the technical-advisory engagement: bringing engineering and technical expertise to a specific problem. Mid-market and enterprise firms buy this for technical assessments, feasibility work, and specialized engineering support. The capability is the same as the government version, sold on the problem rather than a code.
