PSC 6695

Overview

The Product Service Code (PSC) system standardizes how the U.S. government classifies the products and services it buys so awards can be tracked, analyzed, and reported across federal systems. PSCs are used on contract actions in FPDS and on public notices in SAM.gov, and the taxonomy is maintained through the Product and Service Code Manual. ⁵

PSC 6695 (Combination and Miscellaneous Instruments) covers combination instruments and certain instrument types not elsewhere classified within the instruments classes. The PSC Manual specifies that 6695 includes flow–pressure instruments, taximeters, and dynamometers, and excludes dental, medical, surgical, and veterinary instruments. Buyers use 6695 when the predominant item is a combination instrument rather than a single-function device captured by another PSC. ¹

What this PSC covers

• Flow–pressure instruments used to measure fluid parameters in combination. ¹
• Taximeters and related fare-metering instruments. ¹
• Dynamometers for measuring force, torque, or power. ¹
• Combination instruments that integrate multiple measurement functions into a single device, when classified as combination instruments. ¹
• Other miscellaneous instruments assigned to this class when no more specific PSC applies. Not specified by official sources ⁵

Coding guidance and boundaries

Select a single PSC based on the predominant product purchased; use 6695 when the requirement centers on a multi-function or combination instrument rather than discrete single-function devices coded elsewhere (for example, 6680 or 6685). PSC 6695 expressly excludes dental, medical, surgical, and veterinary instruments, which fall under medical PSCs. ¹

Where 6695 appears in federal systems

• FPDS: PSC is data element 8A (Product or Service Code), required on most awards; it draws values from the PSC Manual, which includes 6695. ³
• SAM.gov: In Contract Opportunities, the field classificationCode represents the PSC designated on a notice (e.g., 6695). ²

Frequently asked questions

• What items are included under PSC 6695?
  The PSC Manual lists flow–pressure instruments, taximeters, and dynamometers under 6695. Items specifically medical, dental, surgical, or veterinary are excluded and should not be coded here. ¹

• How should a buyer distinguish between PSC 6680 and PSC 6695?
  Use 6680 when procuring single-function flow, level, or mechanical motion instruments. Use 6695 when the predominant item is a combination instrument (e.g., integrated flow–pressure measurement) rather than separate devices. ¹

• Are medical or dental instruments ever appropriate for PSC 6695?
  No. The exclusion explicitly states that dental, medical, surgical, and veterinary instruments are not covered by 6695 and should be coded under the appropriate medical PSCs. ¹

• How is PSC used in FPDS reporting?
  FPDS requires agencies to populate element 8A (Product or Service Code) with a valid PSC from the manual. This enables standardized reporting of “what was bought” across contract actions, including when the code is 6695. ³

• Does SAM.gov require a PSC on opportunity notices?
  Yes. In the SAM.gov Contract Opportunities payload, classificationCode is the PSC. Notices typically include both PSC and NAICS to describe the requirement; classificationCode may be set to 6695 when applicable. ²
