Sigma Products & MFG

Sigma Products & MFG, a woman-owned small business manufacturer based in Fort Mill, South Carolina, supplies self-indicating thermometers and wet bulb-globe temperature indicators to the Defense Logistics Agency as a prime contractor operating entirely on full-and-open procurements without set-aside designations, though some of its underlying IDV vehicles carry total small business set-aside framing. The company manufactures precision temperature measurement devices under NAICS 334519 (Other Measuring and Controlling Device Manufacturing) and PSC code 6685 (Pressure, Temperature, and Humidity Measuring Instruments), with 198 prime awards totaling $6.6 million in combined potential value since 2002 and no subcontract footprint.

Customer concentration is extreme and narrow. DLA Aviation alone accounts for 129 of 191 awards (96% coverage) and $3.8 million in combined potential value, with DLA Troop Support Medical (30 awards, $1.4 million) and DLA Land and Maritime (27 awards, $1.3 million) forming a secondary tier. The remaining 3 awards to DLA corporate and 2 to the Army round out the portfolio. Both the award-count and potential-value rankings converge on DLA Aviation dominance — the vendor has essentially built a single-customer business around fulfilling delivery orders and purchase orders for thermometers against multiple DLA Aviation IDVs. Place of performance is concentrated in Tega Cay and Fort Mill, South Carolina.

Vehicle position reflects three named IDV relationships with DLA Aviation. A newly awarded single-award Indefinite Delivery Contract (November 17, 2025, ceiling $522,571.14, ultimate completion November 16, 2030) complements two earlier IDVs: a $433,699.63 total small business set-aside running through December 2025 and a $250,000 contract running through May 2028. The top five parent vehicles in the source data are lower-ceiling IDVs (SPE4A615D5140 through SPE4A621DC016 and SP020005D8014), each carrying six to fourteen task orders and combined potentials ranging from $19 thousand to $331 thousand, reflecting typical DLA Aviation delivery-order usage patterns — many small, frequent transactions rather than large consolidations.

Activity has been steady but unspectacular. The vendor received 8 awards in 2022, 8 in 2023, 7 in 2024, 11 in 2025, and 2 in the first four months of 2026, suggesting moderate annual ordering rhythm with slight acceleration in 2025. Only 2 awards (combined potential value $48 thousand) face ultimate completion inside the next twenty-four months, indicating minimal recompete exposure in that window — most of the vendor's work runs under long-standing IDV relationships with DLA that renew by recompete or sole-source extension rather than through frequent full-and-open repricing. The vendor's combined dollars obligated across all awards stand at $4.2 million, or 64% of combined potential value, reflecting partial drawdown of ceiling authorities.

The vendor's federal work comprises routine, repetitive procurement of specialized instruments: individual delivery orders and purchase orders for self-indicating thermometers and wet bulb-globe temperature indicators in dollar ranges of $1,400 to $85,000, with modal order values in the $5,000 to $25,000 band. Representative recent awards include a $23,916.60 delivery order from DLA Aviation on April 8, 2026, a $34,861.85 purchase order from DLA Land and Maritime on November 18, 2025, for 157 wet bulb-globe temperature devices, a $67,397.25 purchase order from DLA Aviation on August 19, 2025, for overheat protection thermostats (NSN 6685006332506), and a $78,910.47 purchase order from DLA Land and Maritime on April 2, 2024, for 393 wet bulb-globe temperature indicators. The vendor has been registered in SAM.gov since 2002 and maintains an active manufacturing footprint for these specialized devices.
