PSC 3630

Overview

Product Service Codes (PSC) are a governmentwide taxonomy for classifying what the U.S. government buys, supporting consistent reporting, analysis, and transparency across procurement systems such as FPDS and SAM.gov. The PSC structure and definitions are maintained in the PSC Manual issued by GSA. ¹
PSC 3630 denotes Clay and Concrete Products Industries Machinery within Federal Supply Group 36 (Special Industry Machinery). The PSC Manual lists “brickmaking machinery” as included in this class. Agencies use this product code when the predominant line item is machinery used in clay or concrete product industries. ¹

What this PSC covers

• Machinery for clay products industries, per the class title. ¹
• Machinery for concrete products industries, per the class title. ¹
• Brickmaking machinery (explicitly included example). ¹
• Product classification under Group 36 (Special Industry Machinery). ¹
• Purchases are coded based on the predominant product (i.e., “what was bought”) as reported in FPDS. ¹
• Examples beyond brickmaking machinery: Not specified by official sources. ²

Adjacent PSC distinctions

• Construction-site equipment such as concrete mixers, vibrators, and pavers is classified under PSC 3895, not PSC 3630. ¹
• Machinery chiefly for plastics or synthetic rubber processing belongs under PSC 3620, not PSC 3630. ¹
• Glass and optical goods manufacturing machinery is covered by PSC 3635, distinct from PSC 3630. ¹

Service and rental coding for this equipment

• Maintenance/repair for special industry machinery uses PSC J036, not product code PSC 3630. ¹
• New installation of this machinery uses PSC N036. ¹
• Leasing or rental of this machinery uses PSC W036. ¹

FPDS reporting note

• Environmental attributes (e.g., energy efficient, biobased) are reported in FPDS data element 8L when applicable; PSC 3630 remains the “what was bought” product code. Use the predominant product to select the PSC. ¹

Frequently asked questions

• What does PSC 3630 include?
  PSC 3630 covers machinery used by clay and concrete product industries and explicitly includes brickmaking machinery. It resides in Group 36, Special Industry Machinery. ¹

• Are there official examples beyond brickmaking machinery?
  The PSC Manual lists brickmaking machinery as an example but does not enumerate additional examples for this class. Not specified by official sources. ²

• How are services for this equipment coded?
  Use service PSCs tied to Special Industry Machinery: J036 for maintenance/repair, N036 for installation, and W036 for lease/rental, rather than product code 3630. ¹

• How is PSC 3630 different from construction equipment codes?
  PSC 3630 is for special-industry manufacturing machinery. Construction-site equipment like concrete mixers and pavers falls under PSC 3895. ¹

• Is there an official NAICS crosswalk for PSC 3630?
  The PSC Manual is the governing source for PSC definitions and does not publish NAICS mappings for 3630. Not specified by official sources. ²
