PSC H291

Overview

The Product Service Code (PSC) system is a government-wide taxonomy used to classify products and services purchased by the U.S. federal government to improve procurement reporting, spend analysis, and category management across systems such as FPDS and SAM; the PSC catalog and management processes are maintained through official guidance and tools. ¹

PSC H291 is the code assigned to equipment- and materials-testing services specific to fuels, lubricants, oils, and waxes. Official PSC resources place this entry within the Equipment-Related Services group and describe it for contract actions where the primary purpose is laboratory testing, inspection, or analytical services related to petroleum products and waxes. ²

• Oil and transformer-fluid testing, including dielectric and contamination testing. ²
• Physical and chemical property testing of waxes and specialty oils. ²
• Equipment- and materials-testing services that support procurement acceptance, quality control, or compliance reporting for fuels and related products. ²

Usage and reporting (optional)

• PSC values are recorded in FPDS data element 8A (“Product or Service Code”); contracting offices should record PSC H291 when the action’s predominant purpose is testing or inspection of fuels, lubricants, oils, or waxes. ¹
• Agencies must select the PSC that best reflects the principal requirement; ancillary supplies or non-testing services should not determine PSC selection when testing/inspection is the primary need. ¹

Frequently asked questions

• Q: When should a contracting officer assign PSC H291 to an action?
  A: Assign PSC H291 when the principal requirement is equipment- or materials-testing services for fuels, lubricants, oils, or waxes (laboratory analysis, acceptance testing, or inspection). Use agency PSC selection guidance and the PSC tool to confirm predominance. ²

• Q: Does PSC H291 cover routine fuel supply purchases?
  A: No. PSC H291 is for testing and inspection services; procurement of fuel products themselves is reported under supply-related PSCs, not the H291 testing classification. ²

• Q: Are medical or diagnostic laboratory services included under H291?
  A: No. PSC H291 covers testing and inspection for fuels, lubricants, oils, and waxes; medical or diagnostic laboratory services are classified under other PSC headings. ²

• Q: Which federal reporting systems use PSC values?
  A: PSC entries are recorded in FPDS and exposed in SAM and other IAE systems to support spend analysis and category management; agencies must follow PSC selection guidance when reporting contract actions. ¹
