PSC K013

Overview

The Product Service Code (PSC) system is a four-character taxonomy used across federal procurement to classify the tangible products and services purchased by the U.S. government. PSC entries are reported in the Federal Procurement Data System (FPDS) and referenced in SAM reporting to enable consistent tracking, analysis, and reporting of government spending. The PSC Manual on Acquisition.gov is the authoritative source for code assignments, descriptions, and policy guidance for managing PSCs and reporting them in federal systems.¹

PSC K013 is the PSC assignment titled “Modification of Equipment — Ammunition and Explosives.” Official PSC resources list K-series codes as modification categories but do not provide a task-level scope or expanded examples for K013 beyond its title; the publicly available PSC Manual and FPDS resources do not elaborate further.¹

What this PSC covers

• Ammunition modification activities, including alterations to existing rounds and ordnance components.
• Explosive ordnance component modification and retrofit work affecting assemblies or subassemblies.
• Retrofit, alteration, or upgrade of explosive-handling, storage, or handling systems.
• Design changes to explosive assemblies where the primary outcome is modification rather than full development.

Specific, line-by-line scope and task examples for K013 are not detailed in the PSC Manual or FPDS guidance; contracting officers must apply the PSC title and reporting rules to select the code that best represents the predominant work for an award.¹

Related NAICS and PSC codes

Authoritative, item-level NAICS crosswalks for individual PSC entries are not published in the PSC Manual or FPDS reference documents and are determined by agencies when reporting award-level NAICS and PSC combinations. For example, related PSCs may include maintenance or repair codes such as PSC J013 (Maintenance/Repair/Rebuild of Ammunition and Explosives) when the work is restorative rather than a modification. Not all PSC entries include an official NAICS crosswalk in public PSC documentation.¹

Reporting & contracting context

Agencies reporting contract actions in FPDS must select the PSC that most closely represents the predominant product or service procured on an award. PSCs are entered in FPDS element 8A and are used for statistical reporting, category management, acquisition planning, and spend analysis. The FPDS glossary and PSC Manual describe reporting rules and the central role of the PSC, but they do not expand the K013 entry beyond its title and standard code listing.²

Frequently asked questions

• Q: How should an agency report a contract that modifies explosive ordnance?

  • A: Record the PSC that best represents the predominant work in FPDS element 8A. If modification of ammunition or explosives predominates the contract’s value, report the award under PSC K013. Consult FPDS reporting guidance for award- and line-item-level reporting rules.²

• Q: Does the PSC Manual provide task-level examples for K013?

  • A: No. The PSC Manual lists and defines PSC groups and individual codes, but it does not provide task-level examples or expanded scope for K013 in the publicly available documentation; agencies apply the title and reporting rules to selection decisions.¹

• Q: Can a contract include both maintenance and modification PSCs?

  • A: Yes. A single contract can include line items reported with different PSCs. FPDS captures the predominant PSC for the overall award (element 8A), while individual CLINs or line items may be reported with their own PSCs when required by reporting rules.²

• Q: Where can I find the official PSC definitions and guidance?

  • A: The authoritative PSC listings and policy guidance are published on Acquisition.gov under the Business Zone (Product and Service Codes Manual); FPDS provides related reporting instructions and a glossary for award reporting.¹
