PSC W066

Overview

The Product Service Code (PSC) taxonomy standardizes how federal agencies categorize products, services, and R&D procured across the government. PSCs appear in FPDS (the Federal Procurement Data System) and are maintained through the PSC Manual; consistent PSC coding enables reliable spend analysis, category management, and cross‑agency reporting. The PSC system is organized by alphanumeric codes grouped into categories (for example, Category W covers lease/rental of equipment), and contracting officers assign PSCs to reflect the predominant product or service delivered under a contract.

The PSC entry W066 — Lease or Rental of Equipment: Instruments and Laboratory Equipment — identifies lease or rental actions where instruments or laboratory equipment are the predominant deliverable and title is not transferred to the government. Agencies use W066 to flag lease/rental actions for laboratory and measurement instruments in FPDS reporting, which supports program managers and analysts tracking leased equipment across federal portfolios. ¹

What this PSC covers

• Lease or rental of laboratory analyzers and bench instruments
• Short‑ or long‑term rental of diagnostic and measurement instruments
• Rental of specialized research and testing equipment
• Equipment provided under lease agreements with operating/support services bundled
• Rental arrangements where title is not transferred and equipment is the predominant deliverable

How agencies commonly record W066 in federal data

• Contract coding guidance: Contracting officers select the PSC that best reflects the predominant product or service. Selection of W066 is appropriate when lease or rental of instruments and laboratory equipment is the primary deliverable. ¹
• FPDS reporting: PSC values are recorded in FPDS data elements; FPDS is the system of record for federal contract reporting and supports public search and reporting by PSC value. ²

Adjacencies and frequently paired PSCs

• W065 — Lease or Rental of Equipment: Medical, Dental, and Veterinary Equipment — adjacent Category W leasing code often used for medical/dental equipment leases. ¹
• J066 — Maintenance, Repair, and Rebuilding of Equipment: Instruments and Laboratory Equipment — commonly paired when sustainment or contractor maintenance is the primary post‑award effort. ¹

Frequently asked questions

• Q: When should a contracting officer use PSC W066 instead of a purchase PSC?
  A: Use W066 when the predominant contract action is a lease or rental and title remains with the lessor; if the predominant result is acquisition of title or a purchase, the appropriate purchase PSC should be used instead. ¹

• Q: Does W066 apply to rentals that include operator or laboratory staff?
  A: W066 covers the lease/rental of equipment itself. If the contract’s primary deliverable is labor (e.g., operator services), code to the service PSC that best represents the labor‑dominant scope. ¹

• Q: Are there FPDS examples showing W066 usage?
  A: Yes. FPDS contains public award records coded with W066 where agencies reported lease/rental arrangements for laboratory and diagnostic instruments; FPDS search and download tools let analysts filter by PSC. ²
