PSC 3010

Overview

The Product Service Code (PSC) system is the U.S. federal government’s standardized taxonomy for classifying goods and services procured across agencies. It enables consistent reporting, analytics, and category management, and is governed by the PSC Manual maintained on Acquisition.gov. The manual provides official definitions, inclusions, and exclusions for each PSC and is updated periodically. ¹

PSC 3010 covers mechanical power transmission devices categorized as “Torque Converters and Speed Changers.” Its scope includes fluid couplings, nonvehicular clutches and couplings, and horizontal right‑angle drive gear units. It excludes automotive torque converters and other vehicular power transmission components (see PSC 2520) and rotary aircraft transmission gear units (see PSC 1615). These boundaries help distinguish 3010 from adjacent classes such as PSC 3020 (gears/chain) and PSC 3030 (belting). ²

What this PSC covers

• Fluid couplings used for mechanical power transmission in nonvehicular applications. ²
• Nonvehicular clutches and couplings integral to torque/speed conversion assemblies. ²
• Horizontal right‑angle drive gear units used to change power direction and output speed. ²
• Reduction gear units and assemblies not designed specifically for motor vehicles or rotary aircraft. ⁴
• Power transmission subassemblies packaged with the above items when principally performing torque conversion or speed change functions. ⁴
• Related hardware necessary for operation of covered converters/speed changers when not more specifically classified elsewhere. ²

Coding notes and boundaries

• Select PSC 3010 when the predominant item is a torque converter, speed changer, or reduction gear unit not designed for vehicles or rotary aircraft. ²
• Use PSC 2520 for automotive torque converters and vehicular power transmission components; do not report those under 3010. ²
• Use PSC 1615 for rotary aircraft transmission gear units; aerospace‑specific designs are excluded from 3010. ²
• Components more precisely described by adjacent power transmission classes—e.g., PSC 3020 (gears/chain) or PSC 3030 (belting)—should be coded to those classes rather than 3010. ⁴

Frequently asked questions

• What does PSC 3010 include?
  It includes fluid couplings, nonvehicular clutches and couplings, horizontal right‑angle drive gear units, and reduction gear units not otherwise specifically classified. These items focus on torque conversion and speed change in nonvehicular applications and exclude vehicle and rotary aircraft transmission components. ²

• When should PSC 2520 be used instead of PSC 3010?
  Use PSC 2520 for automotive torque converters and other vehicular power transmission components. Items designed primarily for vehicles belong under 2520 and should not be reported under PSC 3010. ²

• Are aircraft transmission gear units part of PSC 3010?
  No. Rotary aircraft transmission gear units fall under PSC 1615. Aerospace‑specific drive mechanisms and components are excluded from PSC 3010 to prevent overlap with aviation classes. ²

• Does an official NAICS crosswalk exist for PSC 3010?
  Not specified by official sources. ¹

• Has the official definition for PSC 3010 changed recently?
  As of April 2025, the scope remains fluid couplings, nonvehicular clutches/couplings, and specified gear units, with vehicular and rotary aircraft exclusions as documented in the PSC Manual. See Acquisition.gov archives for prior editions and historical context. ²
