PSC 5510

Overview

The Product Service Code (PSC) system is the federal government’s standard taxonomy for classifying the products and services bought on contract. Agencies record PSCs in systems such as the Federal Procurement Data System (FPDS) and SAM.gov to enable consistent reporting, spend analysis, and category management; the General Services Administration maintains the official PSC Manual with code definitions and usage guidance. ¹
PSC 5510 identifies “Lumber and Related Basic Wood Materials.” Per the PSC Manual, it covers base wood commodities such as dimensional lumber, flooring, timbers, poles, ties, siding, molding, and stakes. Contract actions predominantly for these items should be coded to 5510; the Manual also instructs recording environmental attributes in FPDS when applicable. ²

What this PSC covers

• Dimensional lumber for construction and general supply. ²
• Wood flooring products. ²
• Mine timbers and heavy support timbers. ²

FPDS reporting notes for PSC 5510

In FPDS, agencies enter the PSC in data element 8A and select any applicable environmental attributes (e.g., biobased, recovered content) in element 8L. When a purchase contains mixed items, the Manual directs coding to the predominant product or service value, which for a lumber‑dominant buy would be 5510. ²

DoD coordinated acquisition assignment

Under DFARS PGI 208.7006, PSC 5510 is assigned to the Defense Logistics Agency Troop Support (DSCP) for coordinated acquisition responsibilities, indicating centralized DoD purchasing management for this commodity class. ³

FAR note: “Manufactured end product” exclusion

FAR 52.225-18 specifies that “manufactured end product” excludes PSC 5510 items, which affects how offerors complete place‑of‑manufacture representations for solicitations that include these materials. ⁴

Frequently asked questions

• What products fall under PSC 5510?
  PSC 5510 covers base wood commodities: dimensional lumber, wood flooring, mine timbers, poles, railroad ties, wood siding, molding, and stakes. It does not include millwork or plywood/veneer, which have separate PSCs (5520 and 5530). ²

• How is PSC 5510 different from PSC 5520 and 5530?
  Use 5510 for lumber/basic wood stock. Use 5520 for millwork (e.g., doors, frames, sashes) and 5530 for plywood and veneered panels. These boundaries are specified in the PSC Manual’s includes/excludes notes. ²
