PSC 3020

Overview

The Product Service Code system is a governmentwide taxonomy that classifies what the U.S. government buys so awards can be recorded, searched, and analyzed in FPDS/SAM. The codes are maintained through the official PSC Manual and are used in contract reporting to describe the purchased product or service at the line‑item level. Agencies and vendors use PSCs alongside NAICS to support reporting, market research, and spend analysis across federal procurement systems. ¹

PSC 3020 is the product code for “Gears, Pulleys, Sprockets, and Transmission Chain.” The PSC Manual specifies that it includes power transmission chain and matched gear sets, and explicitly excludes reduction gears, which fall under PSC 3010. Agencies apply PSC 3020 when the predominant deliverable is these mechanical power transmission components. ²

Frequently asked questions

• What does PSC 3020 include and exclude?
  The PSC Manual lists power transmission chain and matched gear sets under PSC 3020, and excludes reduction gears, which belong in PSC 3010. ²

• How is PSC 3020 different from PSC 3010?
  PSC 3010 covers torque converters and speed changers (including reduction gears). PSC 3020 covers gears, pulleys, sprockets, and transmission chain, but not reduction gears. ²

• Are there service PSCs for installation or maintenance tied to this equipment?
  Yes. Services are coded with the “30” family service PSCs such as J030 (maintenance/repair), N030 (installation), K030 (modification), L030 (technical representative), and W030 (lease/rental). ²

• Where is the PSC captured in contract data systems?
  The PSC is entered in FPDS data element 8A and used for federal reporting; environmental attributes are tracked in element 8L. These policies and data fields are defined in the PSC Manual. ¹

• Does the Manual specify environmental criteria unique to PSC 3020?
  Not specified by official sources. Environmental reporting guidance in the Manual applies generally across PSCs via FPDS element 8L rather than to specific product codes. ¹
