PSC X1KF

Overview

The Product Service Code (PSC) system is the standardized taxonomy the U.S. federal government uses to classify goods and services acquired through procurement. PSC codes support FPDS and SAM reporting, enable spend analysis and category management, and are maintained and published through the PSC Manual on Acquisition.gov.¹

The PSC entry X1KF identifies lease or rental arrangements for dredging facilities and related dredging plant in federal procurement records. Federal guidance that groups dredging activity for size‑standard and reporting purposes lists X1KF as “Lease/Rental of Dredging Facilities” and treats it with other dredging PSCs when extracting FPDS contract data for SBA and agency analysis.²

What this PSC covers

• Equipment-lease arrangements for dredging plant and attendant machinery.
• Short- and long-term rental of cutterhead, trailing-suction, and pipeline dredges.
• Lease of dredging support barges and attendant pumping/transfer systems.
• Provision of fully operated dredging units as a leased service (equipment plus crew).
• Site-specific rental of dredging workspaces, staging areas, or temporary plant facilities.

Related NAICS and PSC codes

Type | Code | Descriptor

• | - | - NAICS | [237990] | Other Heavy and Civil Engineering Construction PSC | [C1KF] | Architect and Engineering Construction — Dredging Facilities PSC | [M1KF] | Operation of Dredging Facilities

Note: the dredging group (including X1KF) is identified together for FPDS/SBA analyses under NAICS [237990].²

Acquisition notes

• Contract classification: Tasks or orders that rent dredging plant (with or without crew) are reported using PSC X1KF in FPDS-based reporting; this distinguishes lease/rental activities from construction, maintenance, or operation PSCs.²
• Common vehicle form: Agencies commonly issue IDIQ or task-order vehicles that include specific task orders to lease dredges for navigation-maintenance or emergency removal; the PSC is applied at the award/task level in FPDS. Not specified by official sources.¹

SBA / size-standard context

SBA’s evaluation of the dredging subindustry within NAICS [237990] used FPDS data that classified dredging contracts with PSCs including X1KF, and the Federal Register discussion lists X1KF among related dredging PSCs. That analysis informs the special size-standard (Dredging) exception under NAICS [237990].²

Frequently asked questions

• Q: What differentiates PSC X1KF from dredging construction PSCs?
  A: X1KF is applied to lease or rental arrangements for dredging plant (equipment with or without crew). Construction PSCs are used for capital construction and contractor-built improvements and are treated separately in FPDS and SBA analyses.²

• Q: Which NAICS is most commonly paired with PSC X1KF?
  A: When the scope is navigation or civil dredging, awards using X1KF are typically reported under NAICS [237990] (Other Heavy and Civil Engineering Construction). Agencies should confirm NAICS at the award level in FPDS records.²

• Q: How does PSC classification affect SBA small-business analysis for dredging?
  A: SBA’s dredging subindustry analysis relied on FPDS records filtered by PSC (including X1KF) to identify dredging contracts and to derive the special size-standard applied within NAICS [237990]. These PSC‑based filters are central to the rulemaking record.²

• Q: Are leased dredges reported differently when provided with operator crews?
  A: The PSC X1KF covers lease/rental of dredging facilities whether equipment is provided with or without attendant plant and personnel; specific reporting of staffing and CLINs in FPDS is governed by agency award details. Not specified by official sources.¹
