PSC B529

Overview

The Product Service Code (PSC) system classifies the supplies, services, and research and development the U.S. federal government buys so agencies can track, analyze, and report spending across procurement systems. PSCs appear in contract reporting and are maintained through the official PSC Manual to ensure consistent coding across awards. ¹

Within Service Category B5 (Special Studies/Analysis), B529 is defined as “Special Studies/Analysis – Scientific Data.” It is used when the predominant requirement is analytical work focused on scientific data and is explicitly categorized as a service (not R&D) under the PSC Manual’s Section C. ²

What this PSC covers

• Non-R&D special studies and analyses performed as services. ²
• Analytical work where scientific data are the principal subject of the effort. ²
• Standalone studies, reviews, or evaluations centered on scientific datasets. ²
• Projects coded within Service Category B5 (Special Studies/Analysis). ²
• Efforts where the predominant deliverable is analysis of scientific data rather than development or engineering. ²
• Situations where “scientific data” is the defining attribute versus “data (other than scientific)” coded under B506. ²

Scope boundaries and adjacent PSCs

• Use B506 when the analysis concerns data that are not scientific in nature. ²
• Use B524 when the primary emphasis is mathematical or statistical methodology. ²
• Use B510 for environmental assessments rather than general scientific data analysis. ²
• Use B533 when the scope is specific to water quality studies. ²
• Select the PSC that reflects the predominant service being purchased, per PSC Manual coding guidance. ²

Frequently asked questions

• What does PSC B529 mean?

  • It is a Service Category B5 code titled “Special Studies/Analysis – Scientific Data,” used for non-R&D analytical services where scientific data are the focus. It sits in Section C (Service Codes) of the PSC Manual. ²

• How is B529 different from B506 or B524?

  • B506 covers studies of data other than scientific; B524 covers mathematical/statistical studies. B529 is reserved for studies focused on scientific data specifically. ²

• Is B529 considered research and development?

  • No. Category B is labeled “Special Studies/Analysis, Not R&D,” and B529 resides in that category under Service Codes. ²

• Are PSC codes used in FPDS reporting?

  • Yes. The PSC Manual states PSCs indicate “what” was bought for each contract action reported in the Federal Procurement Data System (FPDS). ²

• Does SAM.gov use PSC codes in opportunity search or posting workflows?

  • Yes. SAM.gov supports searching contract opportunities by PSC, reflecting their use in public-facing procurement workflows. ³
