PSC 3436

Overview

The Product Service Code (PSC) system categorizes the products and services the U.S. government buys so contract actions can be tracked, analyzed, and reported in FPDS/SAM. Codes and definitions are maintained in the PSC Manual and are used on each award to indicate what was purchased. ¹
PSC 3436 identifies “Welding Positioners and Manipulators,” a product class within Federal Supply Group (FSG) 34 (Metalworking Machinery). The class title is the official descriptor used for coding purchases of equipment designed to position or manipulate workpieces or welding heads during welding operations. ²

What this PSC covers

• Welding positioners used to hold and orient workpieces for welding operations. ²
• Welding manipulators used to position or move welding heads or torches relative to the workpiece. ²
• Equipment purchased as end items whose primary purpose is workpiece/torch positioning for welding. ²
• Industrial machinery in FSG 34 coded under this class when the predominant purpose is positioning or manipulation for welding. ²
• Reporting under this PSC follows FPDS rules to select the code matching the predominant item being procured. ²
• Detailed inclusions or exclusions beyond the class title: Not specified by official sources. ²

FPDS/SAM reporting notes

• The PSC is entered in FPDS as data element 8A to indicate “what” was bought; select the code based on the predominant product on the action. ²
• Environmental attribute reporting (if applicable) is captured separately in FPDS data element 8L and is independent of PSC selection. ²

Frequently asked questions

• What does PSC 3436 cover?
  It covers welding positioners and manipulators—equipment used to hold, orient, or otherwise manipulate the workpiece or welding head for welding processes. This is the official class title within FSG 34 and is used for coding procurements of such equipment. ²

• How is PSC 3436 different from PSC 3431, PSC 3432, and PSC 3433?
  Those adjacent classes cover welding power/process equipment (arc, resistance, gas). PSC 3436 is for positioning/manipulation equipment used with welding, not the welding power source or process equipment itself. ²

• Are consumables or accessories coded under PSC 3436?
  Consumables and many accessories are categorized under PSC 3439 (Miscellaneous Welding, Soldering and Brazing Supplies and Accessories) or other applicable classes, rather than 3436. Use the code that best matches the predominant item. ²

• Who manages DoD coordinated acquisition for PSC 3436?
  Assignments are maintained in DFARS PGI 208.70. A specific coordinated acquisition assignment for PSC 3436 is not identified in the public listing; if none is specified, no unique lead activity applies for this class. Verify current assignments before coding. ³

• Does an official NAICS-to-PSC crosswalk specify NAICS for PSC 3436?
  Not specified by official sources. Agencies should select NAICS based on the scope of work and industry of the principal purpose, and PSC based on “what” is bought. Crosswalks may exist informally, but they are not authoritative. ¹
