PSC 3660

Overview

The Product Service Code (PSC) system standardizes how the U.S. federal government classifies what is being purchased so spending can be tracked, analyzed, and reported in systems such as FPDS and SAM. PSCs are maintained in the PSC Manual on Acquisition.gov and are the authoritative reference used across federal procurement. ¹
PSC 3660 covers Industrial Size Reduction Machinery within Federal Supply Group 36 (Special Industry Machinery). The PSC Manual states that 3660 includes general-use machinery related to two or more manufacturing industries and excludes chemical-products machinery, construction/mining crushing and screening equipment, and maintenance-shop mixers. ²

• G2X — PSC 3680 (Foundry machinery, related equipment and supplies)

What this PSC covers

• General‑purpose industrial machines used to reduce the size of materials across multiple manufacturing industries, as opposed to equipment tailored to a single industry. ²
• Size‑reduction equipment intended for broad, multi‑industry applications rather than chemical‑specific or construction/mining‑specific processes. ²
• Machinery performing reduction functions aligned with manufacturing operations where no more specific PSC applies within Group 36. ²
• Equipment classified here when its primary use spans at least two manufacturing sectors per the PSC Manual’s scope note. ²
• Not within scope: chemical products crushing/pulverizing machinery; construction/mining crushing, pulverizing, screening, and mixing machinery; maintenance/repair shop mixers. ²

Boundaries and exclusions

PSC 3660 is expressly limited to general‑use size‑reduction machinery that serves two or more manufacturing industries. It excludes chemical‑products machinery, and construction/mining type crushing, pulverizing, screening, and mixing machinery, as well as maintenance and repair shop mixers. ²

Services versus products (related service PSCs)

When the need is for services related to special‑industry machinery—not the purchase of the machinery itself—use the service PSCs for maintenance/repair (J036), installation (N036), modification (K036), or leasing (W036), rather than product PSC 3660. ²

Reporting considerations (FPDS environmental attributes)

FPDS captures the PSC in data element 8A and environmental attributes (e.g., energy efficient, biobased) in data element 8L. Agencies should select attributes that match the predominant product on the action; the PSC Manual provides the definitions and cautions on correct selection. ²

Frequently asked questions

• What does PSC 3660 include?
  PSC 3660 encompasses general‑use industrial size‑reduction machinery used across at least two manufacturing industries. It is intended for equipment that is not more appropriately classified under a specialized PSC within Group 36. ²

• How is PSC 3660 different from PSC 3650 or construction/mining equipment codes?
  Use PSC 3650 for chemical or pharmaceutical manufacturing machinery. Construction/mining type crushing, pulverizing, screening, and mixing equipment is excluded from 3660 and belongs under construction/mining classes, not Group 36 general use. ²

• Are specific equipment examples (e.g., named machine types) listed for 3660?
  The PSC Manual provides scope notes and exclusions for 3660 but does not enumerate specific example machines for this class. Not specified by official sources ¹.

• Should maintenance, installation, or leasing of size‑reduction machinery use 3660?
  No. Services are coded under service PSCs for special‑industry machinery such as J036 (maintenance/repair), N036 (installation), K036 (modification), or W036 (lease/rental), not under the product PSC 3660. ²

• Does the PSC Manual specify brand, performance thresholds, or domestic preference rules for 3660?
  The PSC Manual does not define brand, performance thresholds, or domestic preference rules specific to 3660. Not specified by official sources ¹.
