PSC 3693

Overview

The Product Service Code (PSC) is a governmentwide taxonomy used to classify the products and services the U.S. federal government buys. PSCs are recorded in FPDS and SAM.gov reporting and maintained through the PSC Manual, enabling consistent categorization, analysis, and visibility into spending trends across agencies. ¹

PSC 3693 covers industrial assembly machines—equipment designed to assemble prefabricated components without further machining. It specifically includes industrial production–type power screwdriving machines and circuit card assembly machines, and excludes machines that combine machining with assembly (material removal), specialized ammunition/ordnance assembly machines, wrapping and packaging machinery, metalworking machinery, and hand tools. ²

What this PSC covers

• Assembly equipment whose primary function is to join prefabricated components without material removal. ⁴
• Industrial production–type power screwdriving machines used in assembly operations. ⁴
• Circuit card/printed wiring board assembly machines. ⁴
• Automated or semi‑automated assembly systems when no machining is performed on the components. ⁴
• Assembly machines not otherwise assigned to a more specific PSC and not performing machining. ⁴

Scope notes, inclusions, and exclusions

• Notes: Includes equipment for assembling prefabricated components; excludes machinery that combines machining and assembly resulting in material removal. ²
• Includes: Industrial production power screwdriving machines; circuit card assembly machines. ²
• Excludes: Specialized ammunition/ordnance assembly machines (see 3690); wrapping and packaging machinery (see 3540); metalworking machinery; hand tools. ²

DoD coordinated acquisition assignment

Under DFARS PGI 208.7006, PSC 3693 is assigned to Defense Supply Center Richmond (DSCR) as a coordinated acquisition item (code “P9”), identifying DLA as the integrated materiel manager for this class of equipment. ³

Service and lease coding for assembly machines

Maintenance, repair, and rebuilding services for special industry machinery are coded under J036; lease or rental of special industry machinery is coded under W036. These service categories are distinct from product code 3693. ⁴

Frequently asked questions

• What does PSC 3693 encompass?
  PSC 3693 is for industrial assembly machines that join prefabricated components without additional machining. It includes industrial production–type power screwdriving machines and circuit card assembly machines and excludes combined machining/assembly equipment and other specifically classified machinery. ²

• When should PSC 3670 be used instead of PSC 3693?
  Use 3670 when the equipment is specifically designed for manufacturing semiconductors, microcircuits, or printed circuit boards; 3670 explicitly excludes assembly machines for mounting discrete components on printed wiring boards, which fall under 3693. ²

• Are packaging and wrapping systems part of PSC 3693?
  No. Wrapping and packaging machinery (e.g., filling, capping, labeling, sealing, strapping) is categorized under 3540, not 3693. ²

• How should maintenance or leasing of assembly machines be coded?
  Maintenance, repair, and rebuilding are coded under J036. Lease or rental is coded under W036. These service PSCs are separate from the product classification in 3693. ⁴

• Which NAICS codes correspond to PSC 3693?
  Not specified by official sources ¹.
