Original Post: 03/09/2026 Modification Post 1: 03/09/2026, Corrects the PSC from 8115 to 8145. DESCRIPTION This Sources Sought Notice (SSN) is issued under FAR Part 10 to determine whether any U.S. domestic manufacturers or distributors can supply expanded polystyrene (EPS) seedling‑growing containers that meet the technical and equipment‑compatibility requirements used within U.S. Forest Service (USFS) nurseries. Th...
View moreThis SSN seeks to confirm whether any U.S.‑based manufacturer can produce EPS containers that are dimensionally and functionally compatible with Forest Service extraction equipment to ensure successful seedling production within limited biological and seasonal timeframes.
SALIENT CHARACTERISTICS (Equal products encouraged)
1) Material
• EPS (expanded polystyrene) or equivalent durability suitable for multi‑year reuse
• Minimize root penetration; maintain structural integrity through multiple extraction cycles
2) Dimensions/Configurations (families or equivalents)
• EPS blocks approx. 14" × 24" × 6"
– 91‑cavity (~1.5" diameter; ~7.9 in³ per cavity)
– 112‑cavity (~1.4" diameter; ~6.6 in³ per cavity)
– 45‑cavity (~2.4" diameter; ~20.5 in³ per cavity)
3) Pattern/Drain‑hole Geometry & Equipment Compatibility
• Block pattern and drain‑hole layout must be geometrically compatible with Gleason
• Seedling Popper extraction equipment used at USFS nurseries
• Trays need to have flexibility and root penetration to accommodate seedling growth and root dept
• Vendors shall provide drawings/specifications demonstrating extraction compatibility
4) Trays/Cone-tainers (if offered)
• Cone‑tainers (e.g., Ray Leach‑type or equivalent): approx. 1.5" diameter × 8.25" depth × ~10 in³
• Compatible tray dimensions approx.: 24" × 12" × 6.75"
5) Packaging & Delivery
• FOB Destination: Placerville Nursery, Camino, CA
• One‑week pre‑delivery notification preferred
REQUEST FOR INFORMATION (≤3 pages, PDF preferred)
Vendors are requested to provide a brief capability statement (PDF preferred, ≤3 pages) addressing:
The U.S. Forest Service (USFS), USDA-FS CSA Southwest 2, issued this Sources Sought Notice to identify domestic manufacturers or distributors capable of supplying expanded polystyrene (EPS) seedling-growing containers. These containers are required for the ENF Placerville Nursery in Camino, California, and must be compatible with existing Gleason Seedling Popper extraction equipment. This market research supports the agency’s evaluation of technical compatibility and informs whether a nonavailability waiver under Made in America requirements is necessary for seedling production.
The required products include EPS blocks measuring approximately 14" x 24" x 6" in various cavity configurations, such as 91-cavity, 112-cavity, and 45-cavity designs. These blocks must feature precise geometric patterns and drain-hole layouts to allow for successful seedling extraction without operational failure. The material must be durable enough for multi-year reuse and engineered to minimize root penetration. Additional items of interest include Ray Leach-type Cone-tainers and compatible trays. Vendors are requested to provide capability statements addressing manufacturing locations, delivery lead times, and engineering documentation to prove equipment compatibility.
This procurement is identified by solicitation number 1160592-1 and falls under NAICS code 326140, Polystyrene Foam Product Manufacturing, and PSC 8145, Specialized Shipping and Storage Containers. The notice is associated with a Small Business Administration (SBA) set-aside. Interested parties must submit responses by March 12, 2026, to the point of contact, Klenise Wallace. Performance is centered at the Placerville Nursery in Camino, California, with delivery terms specified as FOB Destination.
