PSC 3432

Overview

The Product Service Code (PSC) system is the federal government’s standard taxonomy for classifying what is bought, enabling consistent entry in FPDS/SAM and supporting spend analysis and reporting. PSCs are defined and maintained through the PSC Manual issued on Acquisition.gov. ¹

PSC 3432 covers Electric Resistance Welding Equipment. The PSC Manual specifies that this class includes electric resistance brazing machines, band saw brazers, and stored-energy resistance welding machines, and it excludes electric induction brazing and soldering machines. Agencies use this PSC when the predominant deliverable is resistance welding equipment. ¹

What this PSC covers

• Electric resistance brazing machines designed for joining metals by resistance heating. ¹
• Band saw brazers and related equipment used to braze saw bands via resistance methods. ¹
• Stored-energy resistance welding machines (e.g., capacitor discharge systems). ¹
• Spot, seam, and projection resistance welding systems when acquired as equipment end items. ¹
• Integrated resistance welding units including controls, power supplies, and fixtures delivered as equipment. ¹
• Replacement power units and controllers when procured as integral components of resistance welding machines. ¹

DoD coordinated acquisition assignment (context)

DFARS PGI coordinated acquisition listings identify Defense Supply Center Richmond (DSCR) as the acquiring activity for a range of metalworking and welding Federal Supply Classes, including 3432. Requiring activities route covered requirements via the coordinated acquisition process outlined in DFARS/PGI 208.70. ²

FPDS reporting considerations

• PSC is captured in FPDS data element 8A; select the PSC that reflects the predominant item purchased on the action. ¹
• Environmental attributes (element 8L) are reported when applicable; however, selection must reflect the specific contract requirement. ¹
• Use PSC product classes (Section D of the Manual) for end items of equipment rather than service codes when the buy is equipment-centric. ¹

Frequently asked questions

• What equipment falls under PSC 3432?

  • The PSC Manual states it covers electric resistance brazing machines, band saw brazers, and stored-energy resistance welding machines, while excluding electric induction brazing and soldering machines. Use this class when the end item is resistance welding equipment rather than services or other welding processes. ¹

• How does PSC 3432 differ from PSC 3431?

  • 3432 is for electric resistance welding equipment. 3431 is for electric arc welding equipment such as gas-shielded arc welders and automatic arc welding machines. Select the class that matches the welding process of the predominant equipment. ¹

• Is there an official NAICS crosswalk for PSC 3432?

  • Not specified by official sources. ³

• Who manages Department of Defense buys for PSC 3432) items under coordinated acquisition?

  • DFARS PGI lists DSCR as the acquiring activity for applicable metalworking and welding FSCs, including 3432. Programs follow DFARS/PGI 208.70 procedures (e.g., MIPR routing) unless an exception applies. ²

• How should a mixed buy be coded when it includes multiple welding equipment types?

  • Code to the predominant item on the action. If resistance welding equipment constitutes the main dollar value or quantity, use 3432; otherwise select the applicable PSC for the predominant item acquired. Ensure the action’s description supports the selected code. ¹
