PSC 3680

Overview

The Product Service Code system categorizes what the U.S. government buys so contract actions can be consistently recorded in FPDS and analyzed across agencies. PSCs are maintained through the PSC Manual and are a required data element for reporting and spend analysis. ¹

Within this taxonomy, PSC 3680 is defined as “Foundry Machinery, Related Equipment and Supplies.” The PSC Manual lists representative inclusions—molding machines, tumbling mills, foundry dextrin, and core paste—and specifies exclusions such as crucible furnaces, cupola furnaces, and foundry hand tools. Use 3680 when the predominant purchase is foundry machinery or the noted supplies. ¹

What this PSC covers

• Foundry molding machines used to form molds for casting operations. ¹
• Tumbling mills employed for cleaning and finishing castings. ¹
• Foundry dextrin used as a binder in sand molding. ¹
• Core paste used in core-making for foundry processes. ¹
• Related foundry equipment and supplies encompassed by the class when they support molding and casting operations. ¹

Frequently asked questions

• What does PSC 3680 include?

  • The PSC Manual lists molding machines, tumbling mills, foundry dextrin, and core paste under 3680. This class applies when foundry machinery or closely related supplies are the predominant items in the purchase, helping agencies consistently categorize foundry-focused procurements for reporting and analysis. ¹

• Are furnaces coded under PSC 3680?

  • No. Crucible furnaces and cupola furnaces are explicitly excluded from 3680 in the PSC Manual. Buyers should code furnaces under their appropriate classes rather than 3680, which is limited to foundry machinery and related supplies like molding equipment and media. ¹

• Are foundry hand tools covered by PSC 3680?

  • No. Foundry hand tools are listed as exclusions from 3680. This class is intended for machinery and certain supplies (e.g., dextrin, core paste) used in foundry processes, not for manual tools, which should be coded under the appropriate tool classes. ¹

• Who manages coordinated acquisition for PSC 3680 within DoD?

  • PGI 208.7006 shows 3680 assigned to DSCR for coordinated acquisition purposes. This coordination signals a designated DoD purchasing lead, helping ensure standardized sourcing and potential economies of scale for requirements within this class. ²

• Is there an official PSC-to-NAICS crosswalk for 3680?

  • Not specified by official sources. The PSC Manual and its document library do not provide an official crosswalk to NAICS for 3680. Agencies may reference internal mappings, but any crosswalks are not authoritative unless published by the governing sources. ³
