Takeda Kaseihin Co.,Ltd.

Takeda Kaseihin Co., Ltd., a Tokyo-based chemical supplier, provides wastewater treatment chemicals and industrial chemicals as a prime contractor to U.S. military installations in the Pacific region, competing exclusively full-and-open with no socioeconomic set-aside designations across a 389-award federal footprint spanning 1999 to April 2026.

Takeda Kaseihin is a for-profit organization registered as a corporate entity with continuous federal vendor registration since January 2004. The company specializes in chemical wholesaling and manufacturing, with primary NAICS codes 424690 (Other Chemical and Allied Products Merchant Wholesalers, covering 313 awards) and 325998 (All Other Miscellaneous Chemical Product and Preparation Manufacturing, covering 61 awards). PSC coding reflects the chemical focus: 6740 (Chemicals) on 277 awards and 6750 (Miscellaneous Chemical Specialties) on 99 awards. Takeda Kaseihin's product portfolio centers on sodium hypochlorite solution (12 percent), sodium fluoride, poly-aluminum chloride, sulfuric acid (75 percent), and diatomaceous earth — all standard wastewater treatment chemicals — supplemented by occasional industrial equipment such as a CNC manual lathe machine delivered to Naval Air Systems Command in 2022.

Customer concentration is extreme and single-threaded. The Department of the Navy Naval Facilities Engineering Command accounts for 349 of 389 awards (90% of volume) and $1.6 million of $7.6 million combined potential value. The remaining active customers — Department of the Army Installation Management Command Pacific Region (4 awards, $349 thousand), Department of the Navy Naval Air Systems Command (2 awards, $149 thousand), Department of the Navy Installations Command (24 awards), Department of the Air Force Pacific Air Forces (3 awards), Department of the Navy United States Pacific Fleet Forces (1 award), and Department of the Navy Naval Supply Systems Command (2 awards) — collectively represent 10% of award count but only 28% of combined potential value coverage. Nearly all Naval Facilities Engineering Command awards flow to support wastewater treatment operations at Naval Air Facility Atsugi, Japan.

Takeda Kaseihin holds two active parent vehicles: a single-award indefinite-delivery requirements contract with Naval Facilities Engineering Command (N6824623D0007) valued at $182,483.22 through September 30, 2026, which covers bulk chemicals for the NAF Atsugi sewage treatment facility, and a single-award blanket purchase agreement with Army Installation Management Command Pacific Region valued at $250,000 through September 30, 2028. Historical IDV activity concentrated on four older Naval Facilities Engineering Command requirements contracts (N6264905D0020 with 171 task orders at $188 thousand combined value, N6264913D0018 with 72 task orders at $157 thousand, N6264910D0024 with 54 task orders at $121 thousand, and N6264918D0048 with 43 task orders at $205 thousand) representing the vendor's legacy footprint. Recent activity shows a sharp year-over-year decline: eight awards in 2022, seven in 2023, six in 2024, five in 2025, and only three in the first quarter of 2026. Representative recent work includes a $17,075.81 delivery order for wastewater treatment chemicals awarded August 5, 2025; a $13,970.73 order for sewage plant chemicals awarded August 21, 2025; and a $7,705.85 order for sodium hypochlorite solution awarded August 28, 2025 — all under the active NAF Atsugi IDV. All federal awards are firm fixed-price with no set-aside designation, issued through full and open competition. The combined potential value of $7.6 million against obligated dollars of $1.2 million reflects the volatility of small delivery-order contracting; the 16% obligation rate indicates substantial unexercised ceiling capacity across the active IDVs.
