Tangram Chemical LLC

Tangram Chemical LLC, doing business as Tangram Co LLC, manufactures and supplies specialized chemical reagents and materials to the Department of the Navy as a prime contractor under total small business set-asides and full-and-open competitive procurements. The company is a small business based in Holtsville, New York, operating as a limited liability partnership and functioning exclusively as a prime — it holds no subcontract awards in the source data.

Tangram Chemical's customer footprint is heavily concentrated with Naval Supply Systems Command (NAVSUP), which accounts for 662 of 807 documented awards (82% by count) and $68.8 million of the $76 million combined potential value (91% by dollars). The top four customers achieve 94% of award count and 95% of potential value, with the Department of the Navy (27 awards, $1.6 million), Defense Logistics Agency Aviation (21 awards, $1.5 million), and the broader Defense Logistics Agency rounding out the active set. This concentration reflects Tangram's role as a recurring supplier to naval logistics rather than a diversified federal vendor.

The company's capability portfolio centers on high-purity chemical reagents, analytical test kits, and specialized materials supporting naval operations. Representative work includes recurring BPA calls for hydrazine solutions (ranging from $57,500 to $150,000 per call), sodium phosphate products ($215,000 to $387,625 across multiple calls), morpholine technical-grade chemicals ($133,500 to $190,000), silica analysis kits ($18,500 to $22,200), chloride solutions ($35,000 to $46,000), and dozens of smaller calls for potassium iodide, ammonium hydroxide, nitric acid reagent, hydrochloric acid, sodium hydroxide, potassium chloride, and technical zinc. All recent calls are firm fixed-price arrangements with ultimate completion dates spanning from mid-2025 through late 2026. The category concentration is split across two primary NAICS codes: All Other Basic Organic Chemical Manufacturing (325 awards) and All Other Basic Inorganic Chemical Manufacturing (197 awards), with 786 of 807 awards falling under Chemicals (PSC code) procurement.

Tangram Chemical holds three active parent BPA vehicles with NAVSUP: a $27 million multiple-award BPA expiring March 31, 2027 (129 task orders documented), a $13 million multiple-award BPA also expiring March 31, 2027 (69 task orders), and a $2.2 million single-award BPA expiring June 29, 2026. All calls under the two larger vehicles are designated as total small business set-asides; the single-award vehicle carries no set-aside. These three vehicles collectively anchor Tangram's federal work, with the majority of individual calls valued between $4,500 and $227,500. The company registered in SAM in December 2001 and has maintained continuous NAVSUP supplier status for over two decades, with award volume averaging roughly 25 awards per year over the past five years (30 in 2022, 29 in 2023, 21 in 2024, 24 in 2025, and 7 documented in 2026 through April).

Activity has remained relatively flat, with recent annual awards declining slightly from peak levels in 2022–2023 to 21 in 2024 before recovering to 24 in 2025. Five awards (combined potential value $499 thousand) face ultimate completion within the next twenty-four months and therefore trigger recompete exposure, though this represents a small fraction of the $76 million portfolio. The combined dollars obligated across all awards stands at $24.6 million (32% of combined potential value), indicating that invoice drawdown against the portfolio remains below ceiling — typical of Navy BPA structures where ceilings are established but actual orders fluctuate with logistics demand.
