PSC L036

Overview

The Product Service Code (PSC) system is a governmentwide taxonomy used in FPDS and SAM to classify the products and services acquired by federal agencies; the PSC Manual (managed on acquisition.gov) maintains and publishes the authorized codes and their descriptors to support consistent spending reporting, analysis, and category management. The PSC L036 appears in the manual as “Technical Representative- Special Industry Machinery.” The manual records that descriptor as the official label for the code but does not publish a line‑by‑line activity list or an exhaustive duties catalog; agencies select L036 when the predominant procurement action is technical representative services related to special‑industry machinery, and the solicitation or statement of work supplies the tasking and limits for a given acquisition.¹

What this PSC covers

• Technical representation services for special‑industry machinery
• Field support and liaison activities between machinery vendors and government users
• On‑site equipment performance verification and acceptance support
• Operator instruction and technical briefings
• Coordination of field service, warranty, and vendor‑provided maintenance
• Installation‑related technical oversight when the predominant service element matches L036
• Detailed task‑level duties and limits — Not specified by official sources¹

Related NAICS and PSC codes

(These neighboring PSCs and installation/maintenance complements appear in the PSC Manual listing for Category L and related N/J categories; specific NAICS crosswalk entries for L036 are published in alignment spreadsheets rather than inline on the descriptor page.)¹

How agencies commonly treat Technical Representative PSCs

• Assignment and authority: Agencies often distinguish a technical representative role from contract administration and contracting officer’s representative duties; DoD guidance on technical representatives at contractor facilities clarifies that a technical representative performs non‑contract‑administration technical duties and is not a contracting officer’s representative.²
• Reporting practice: FPDS requires that the PSC data element 8A be set to the predominant product or service; when on‑site technical representation for special‑industry machinery is the principal service, L036 is the appropriate entry for data element 8A in FPDS records.³

Frequently asked questions

• What exactly does L036 mean on a solicitation or award?
  A: L036 is the PSC label indicating the procurement’s predominant service is technical representative support for special‑industry machinery. The PSC Manual lists the descriptor but does not provide a detailed task list; agencies define specific duties in the solicitation or statement of work.¹

• Is L036 a product code or a service code?
  A: L036 is a service PSC in Category L (Technical Representative), used to record services rather than tangible products in FPDS data element 8A.¹

• Are NAICS codes mapped to L036 in the PSC Manual?
  A: The PSC Manual publishes alignment spreadsheets for crosswalks, but descriptor pages do not always show a single inline NAICS mapping; consult the PSC alignment spreadsheet or the acquiring agency’s solicitation for the NAICS code used with a specific procurement.¹

• Can a technical representative be located at a contractor facility under DoD rules?
  A: Yes. DFARS subpart 242.74 describes procedures for assigning technical representatives at or near contractor facilities and clarifies that such representatives perform non‑contract‑administration technical duties separate from COR responsibilities.²
