PSC 3640

Overview

The Product Service Code (PSC) system is the federal standard for classifying the goods and services the government buys so spending can be tracked, analyzed, and reported in FPDS and related acquisition systems. Codes and definitions are maintained in the PSC Manual published by GSA on Acquisition.gov. ¹

PSC 3640 is a product code in Federal Supply Group 36 (Special Industry Machinery) titled “Tobacco Manufacturing Machinery.” The April 2025 PSC Manual lists this class by title only and does not provide includes/excludes text specific to this class. Agencies typically use it when the predominant item purchased on an award is tobacco‑product manufacturing machinery. ¹

Frequently asked questions

• What is the official definition of PSC 3640?

  • The PSC Manual lists 3640 under Group 36 as “Tobacco Manufacturing Machinery” and provides no additional includes/excludes text. Agencies should apply it when the machinery is the predominant item purchased on the award. ¹

• Does the PSC Manual specify what machines are included or excluded under 3640?

  • Not specified by official sources; the April 2025 PSC Manual provides only the class title for 3640. Buyers should select the code based on the predominant product being procured within the Group 36 scope. ¹

• Which PSC should be used for repairing or installing tobacco manufacturing machinery?

  • Use service PSCs in the 03x6 family: J036 for maintenance/repair, N036 for installation, and K036 for modification of special industry machinery. ¹

• How do PSC and NAICS relate on a federal award?

  • PSC identifies what was bought, while NAICS identifies the supplier’s industry classification. Both are reported separately in procurement systems and forms such as DD 2579; the PSC Manual does not provide a crosswalk between PSC and NAICS. ²

• Is vaping/e‑cigarette manufacturing equipment explicitly covered under 3640?

  • Not specified by official sources; the Manual does not list subtypes for 3640. Selection should follow the predominant product purchased and the Group 36 context for special industry machinery. ¹
