PSC 6099

Overview

The Product Service Code (PSC) is a government-wide taxonomy used to classify the products, services, and research and development the U.S. federal government buys. PSCs support procurement reporting and analytics in systems such as FPDS and are governed by the official PSC Manual published on Acquisition.gov. ¹

PSC 6099 — Miscellaneous Fiber Optic Components — is a residual product code within Federal Supply Group (FSG) 60 for fiber‑optic items that cannot be placed in a more specific FSG 60 class (for example, 6015, 6020, 6030, 6060). The PSC Manual indicates that items with well‑defined functions belong in their specific FSG 60 classes, reserving 6099 for residual, otherwise‑unclassified fiber‑optic components. ¹

What this PSC covers

• Catch‑all fiber‑optic items not classifiable in a more specific FSG 60 class (e.g., 6015, 6020, 6030, 6060). ¹
• Unspecified or legacy fiber‑optic components and parts whose functions are not described elsewhere in Group 60. ¹
• Residual fiber‑optic hardware associated with, but not integral to, defined devices, interconnects, or cable assemblies. ¹
• Not included: fiber‑optic kits/sets classifiable under 6080, test instruments categorized in the Instruments and Laboratory Equipment group, or end items classified in their own equipment FSCs. ¹
• Not included: fiber‑optic cable assemblies (classifiable under 6020) rather than communication cable assemblies in 5995. ¹
• Items used solely for illumination or image transfer are typically classed under 6035 (not 6020); 6099 is not a substitute for those defined classes. ¹

Type | Code | Descriptor

• | - | - PSC | 6015 | Fiber Optic Cables PSC | 6020 | Fiber Optic Cable Assemblies and Harnesses PSC | 6030 | Fiber Optic Devices PSC | 6060 | Fiber Optic Interconnectors

Coding boundaries and common exclusions

• Fiber‑optic communication cable assemblies belong in 6020; communication cable assemblies class 5995 specifically excludes fiber‑optic cable assemblies. ¹
• Illumination or image‑transfer devices are in 6035; communication/data transmission items are mapped to other FSG 60 classes, not 6099. ¹
• Certain medical fiber‑optic endoscopes fall in Group 65 (e.g., class 6515) and are therefore outside FSG 60. ¹
• The PSC Manual documents current fiber‑optic classes, including 6099, in the April 2025 edition; any prior reinstatement timing is not specified by official sources. ¹

FPDS coding considerations

In FPDS, PSC is recorded in data element 8A to indicate “what” was purchased. When multiple items are bought, the PSC should reflect the predominant product. Environmental attributes, where applicable, are reported separately in element 8L and are independent of the PSC selection. ¹

Frequently asked questions

• What is PSC 6099 used for?
  • It is reserved for fiber‑optic components that do not fit a more specific FSG 60 class. If the item’s function clearly matches another class (e.g., 6030 devices or 6060 interconnectors), use that specific code instead to ensure accurate reporting and comparability. ¹
• How does 6099 differ from 6020 Fiber Optic Cable Assemblies?
  • 6020 covers finished assemblies and harnesses with processed ends or fittings for communications/data transmission. 6099 should not be used for items that meet the 6020 definition; use 6099 only when no specific class applies. ¹
• Should fiber‑optic test instruments be coded under 6099?
  • No. Test sets and instruments are classified in the Instruments and Laboratory Equipment group (outside FSG 60). If you are buying a test set or instrument, use the appropriate instruments PSC rather than 6099. ¹
• Are illumination or image‑transfer fiber‑optic items coded in 6099?
  • Typically no. Illumination and image‑transfer items fall under 6035. Communications and data‑oriented items map to other FSG 60 classes. Use 6099 only when the item cannot be properly placed elsewhere in Group 60. ¹
