PSC K059

Overview

The Product Service Code (PSC) framework is the federal standard for classifying products and services procured by U.S. Government agencies. PSC entries are recorded in contracting systems such as the Federal Procurement Data System (FPDS) and used in award reporting, spend analysis, and portfolio management; guidance and the PSC Manual are referenced by acquisition policy for authoritative names and usage. ¹

PSC K059 is labeled “Modification of Equipment‑ Electrical and Electronic Equipment Components.” It is applied to contract line items where the predominant effort is modification or upgrade of electrical or electronic equipment components — for example hardware retrofits, component replacements that change equipment capability, and firmware or embedded‑software updates performed as part of a physical equipment modification. FPDS award records and agency entries commonly use this PSC to reflect hardware upgrade scope and related component work. ²

What this PSC covers

• Modification of electrical or electronic equipment components
• Electrical control system upgrades and reconfiguration
• Electronic subsystem retrofits and component replacements
• Firmware or embedded‑software updates when integral to a hardware modification
• On‑site modification work and factory retrofit programs
• Integration of replacement electronic components into existing equipment

Related NAICS and PSC codes

Typical contracting contexts

• Agency equipment modernization and recapitalization programs where assemblies are altered, upgraded, or reconfigured often use PSC K059; these actions are frequently paired with engineering or systems‑integration NAICS codes when the scope includes design, testing, or modification engineering. ²

Frequently asked questions

• Q: Where are PSC definitions and official lists published?
  A: The authoritative PSC definitions and the Product and Service Codes Manual are referenced via acquisition policy and contract reporting guidance; contracting officers and data stewards should consult the PSC Manual and FPDS documentation for official code names and usage. ¹

• Q: How does PSC K059 differ from J059 and N059?
  A: K059 denotes modification or upgrade work that changes capability; J059 denotes maintenance, repair, or rebuilding; N059 denotes installation. Choose the PSC reflecting the predominant effort on the contract line item. ¹

• Q: Which NAICS codes commonly appear with PSC K059?
  A: Engineering and technical services NAICS such as 541330 commonly co‑occur with K059 on FPDS records when the modification scope includes engineering design, testing, or systems integration work. ²

• Q: Are firmware or software changes covered by PSC K059?
  A: Firmware or embedded‑software updates are classified under K059 when they are integral to and performed as part of a physical modification to electrical/electronic components; standalone software development or IT services typically require other PSC/NAICS designations. ²
