About the company
Lee Engineering Supply Company, Inc., doing business as Amerimex USA, is a small business prime contractor based in Harahan, Louisiana, supplying maritime and industrial parts and services to the Department of the Navy, the Military Sealift Command, and related federal agencies. The vendor operates predominantly as a prime contractor (99% of recent awards) competing full-and-open, with approximately half of recent awards using total small business set-asides. The company specializes in air compressor parts, overhaul kits, mooring lines, corrosion inhibitors, and related vessel maintenance equipment for naval and sealift vessels.
Customer concentration is extreme: the Department of the Navy Military Sealift Command accounts for 197 of 256 total awards (77% of the portfolio) and $3.7 million of the combined $4.5 million potential value (82% of dollars). The Department of Homeland Security US Coast Guard places a distant second at 21 awards valued at $128 thousand combined, followed by the Department of the Navy (not MSC) with 10 awards ($212 thousand), the National Oceanic and Atmospheric Administration with 5 awards ($101 thousand), and Defense Logistics Agency Aviation with 5 awards ($99 thousand). The source portfolio spans 11 distinct customer agencies but is operationally driven by MSC demand.
Representative prime work includes a $274,994 firm fixed-price purchase order from Military Sealift Command (January 2023) for Sperre air compressor parts supporting the USNS John L. Canley (T-ESB 6); a $65,055 order from the Department of the Navy (July 2024) for air compressor parts on a T-ESB vessel; a $55,350 total small business set-aside from Military Sealift Command (September 2025) for Sperre Air Power air compressor parts; a $54,040 total small business set-aside from NOAA (August 2026) for mooring lines supporting the NOAA Ships Oscar Elton Sette and Nancy Foster; and recurring $15,000–$45,000 orders for air compressor parts, overhaul kits, and mufflers across T-AKE and T-ESB vessel classes. The vendor does not sit on any government-wide vehicles, BPAs, or IDIQs; all work flows through individual firm-fixed-price purchase orders issued directly by customer agencies.
Activity has been episodic. The vendor recorded two awards in 2022, a peak of 17 in 2023, 12 in 2024, and has declined to 7 in 2025 and 3 in 2026 (as of late August). Combined dollars obligated have slightly exceeded combined potential value across the portfolio (103%), indicating actual invoiced volume on prior-year awards has exceeded initial ceilings. No recompete cliff signal is present in the source material.
The vendor subcontracts minimally: two sub-awards in the source data, one with Vigor Marine LLC (December 2023, ship service work on the USNS John Lewis) and one with The Dutra Group (October 2023, OWS filters for process equipment). The source describes Amerimex USA as a "long-standing vendor" to MSC with "prior contract experience ranging from $10,000 to $275,000" and notes the company has maintained SAM.gov registration since 2004. Primary NAICS codes reflect the portfolio: Commercial and Industrial Machinery and Equipment Repair and Maintenance (119 awards), Air and Gas Compressor Manufacturing (44 awards), and Ship Building and Repairing (26 awards). Top PSC codes are Miscellaneous Ship and Marine Equipment (134 awards) and Maintenance/Repair/Rebuild of Equipment–Ship and Marine Equipment (34 awards).
