PSC Y1KC

Overview

The Product Service Code (PSC) system is the federal taxonomy used to classify products and services in government procurement reporting. PSC values populate FPDS reporting fields (for example, FPDS data element 8A) and are maintained through the PSC Manual on Acquisition.gov, which is the definitive source for PSC definitions, grouping, and usage guidance. ¹

PSC Y1KC — Construction of Mine Fire Control Facilities — is a Group Y construction-category PSC used to mark procurement actions where the predominant work is construction of mine fire-control structures and associated civil works. The PSC Manual lists Y1KC alongside related construction and facilities PSCs and differentiates it from maintenance and repair PSCs that cover similar assets. ¹

Reporting & FPDS notes

PSC values are entered in FPDS as the “Product or Service Code” (data element 8A); related environmental or characteristic attributes are reported in data element 8L. Agencies should select the PSC that reflects the predominant product or service for the action, consistent with the PSC Manual’s selection guidance. ¹

Frequently asked questions

• Q: What specifically does PSC Y1KC indicate on an FPDS record?
  A: PSC Y1KC indicates the predominant bought item is construction of mine fire control facilities. It flags actions where construction work for mine fire-control facilities is the primary scope rather than maintenance or repair. ¹

• Q: How does Y1KC differ from Z1KC and Z2KC?
  A: Y-series PSCs (for example, Y1KC) identify construction procurements. Z1-series denotes maintenance (for example, Z1KC); Z2-series denotes repair or alteration services (for example, Z2KC). Choose the PSC that best matches the primary work type. ¹

• Q: Which NAICS codes should be used with Y1KC?
  A: The PSC Manual does not publish a single definitive NAICS mapping for Y1KC; NAICS selection depends on the specific construction activities and industry classification of the work performed. Not specified by official sources ¹

• Q: Where do I record the PSC when preparing a solicitation or recording an award?
  A: Record the Product or Service Code in FPDS data element 8A. Use the PSC Manual for code selection rules and consult FPDS help for the technical steps to enter or update PSC values. ²
