PSC 4020

Overview

The Product Service Code system categorizes what the U.S. government buys so contract actions can be consistently coded, searched, and analyzed across federal procurement systems such as FPDS and SAM.gov; the PSC Manual maintained by GSA provides the authoritative definitions and usage rules. ¹

4020 designates fiber rope, cordage, and twine as product purchases within Federal Supply Group 40 (Rope, Cable, Chain, and Fittings). Official notes define fiber rope as flexible twisted strands of manila, nylon, or other fibers; cordage as ropes or cords used in rigging (per item‑name parameters); and twine as two or more strands twisted together. Items furnished with attachments or terminations remain in 4020 unless a more specific item name applies. ¹

What this PSC covers

• Bulk, general‑use fiber rope made from natural or synthetic fibers (e.g., manila, nylon, other fibers). ¹
• Cordage used in rigging applications when classified by applicable item‑name parameters. ¹
• Twine composed of two or more twisted strands. ¹
• Fibrous rope and fibrous cord products without specialized, application‑specific designations. ¹
• Fibrous cord assemblies and related fibrous twine items. ¹
• Items furnished with attachments/terminations, unless a more specific item name governs classification. ¹
