Rigaku Americas Holding, Inc.

Rigaku Americas Holding, Inc., a foreign-owned, for-profit scientific equipment manufacturer headquartered in Spring, Texas, sells X-ray analytical instrumentation and specialized maintenance services to federal agencies primarily as a prime contractor (88% of recent awards), competing in full-and-open procurements with no set-aside designations. The vendor operates through its Rigaku Americas Holding Inc. Division and maintains a subsidiary, Rigaku Innovative Technologies, Inc.

Rigaku's concrete capability portfolio centers on X-ray diffraction and X-ray fluorescence spectrometer systems — instruments used for materials analysis, structural characterization, and analytical testing — paired with maintenance, repair, and technical support services. Representative prime work includes a $1,024,026 purchase order from the National Institute of Standards and Technology (awarded September 2023) for a CHIPS X-ray diffractometer system with four years of optional preventative maintenance, a $466,363 definitive contract from the Bureau of Engraving and Printing (September 2024) for a wavelength-dispersive X-ray fluorescence spectrometer at the Eastern Currency Facility, and a $255,120 purchase order from the National Institute of Diabetes and Digestive and Kidney Diseases (April 2024) for a silver service contract covering high-value X-ray diffraction instrumentation including an Eiger 4M detector and Haskris chiller supporting structural biochemistry research. Rigaku also delivers routine annual maintenance contracts — for example, a $33,821 service agreement from the Department of Energy's National Energy Technology Laboratory (May 2025) for two Rigaku instruments, and a $56,210 one-year silver service agreement from the Environmental Protection Agency (January 2025) for a Rigaku Primus II wide-dispersive X-ray fluorescence analyzer in Denver, Colorado. The vendor supplies equipment and parts as well; recent orders include a $448,595 ZSX Primus IV sequential wavelength-dispersive X-ray fluorescence spectrometer from the Department of Energy (April 2026) and a $158,000 HYPIX-6000HE hybrid photon counting detector system from the Air Force Academy (September 2025).

Customer concentration tracks across research and technical agencies rather than a single dominant customer. The top five customers by award count — the Office of Naval Research (6 awards, $74 thousand), the Department of Energy's Office of Fossil Energy (4 awards, $534 thousand), the National Cancer Institute (2 awards), NASA's Shared Services Center (2 awards, $28 thousand), and Naval Sea Systems Command (2 awards, $212 thousand) — account for 48% of awards. By potential value, concentration shifts toward higher-ticket instrument procurements: the National Institute of Standards and Technology anchors $1 million (a single award), the Department of Energy carries $534 thousand across four awards, the Bureau of Engraving and Printing holds $466 thousand, the Department of the Interior's Wyoming Region holds $313 thousand (a multi-year preventative maintenance contract), and the National Eye Institute holds $255 thousand. The two rankings diverge notably — NIST's single large equipment buy versus the Navy's repeated smaller service calls — reflecting Rigaku's dual role as both equipment supplier and incumbent maintenance provider. Rigaku serves 21 distinct customer agencies across recent activity.

Activity has accelerated sharply: one award in 2021, two in 2023, nine in 2024, seventeen in 2025, and three in the first two weeks of 2026. Eight awards (combined potential value $1 million) complete within the next twenty-four months, creating moderate recompete exposure in maintenance-services categories where Rigaku typically holds incumbent status.

Rigaku's parent-vehicle footprint is sparse; the source identifies only two task orders under Multiple Award Schedule contracts and single task orders under an Indefinite Delivery Contract and a Responsive Strategic Sourcing for Services vehicle. The vendor does not appear to sit on major GWACs or government-wide IDIQs, limiting its leverage as a teaming prime.

As a subcontractor, Rigaku provides equipment and maintenance services under primes including Illumina, Inc. (supporting National Cancer Institute operational task orders for FY26–FY27 lab equipment maintenance), Weems Design Studio, Inc. (supporting NCI FY25 operational task order maintenance), Caci Technologies, LLC (contributing hardware components to an October 2024 electro-optic infrared technology research and development sub-award), and Triad National Security, LLC (supplying industrial fixtures and equipment components under the Los Alamos National Laboratory management and operating contract, April 2024). Sub-award volume is modest (four awards, 12% of the footprint), and subcontract work does not substantially diversify Rigaku's capability focus — maintenance and equipment supply remain central.

Award history shows Rigaku has been active in federal contracting since at least 2015. The source notes the vendor was previously registered under a different UEI (MF57ENCBSB57) and transitioned to the current UEI (TN8FW9VP39W1) via modifications to several existing contracts, including the EPA Region 10 maintenance agreement and the Department of Energy's National Energy Technology Laboratory service contract. Combined potential value across the 33 recent awards totals $3.6 million, with $3.5 million obligated (98% realization), indicating these contracts have moved from option or award phases into active execution. The vendor's category concentration reflects its market position: electronic and precision equipment repair and maintenance (12 awards), analytical laboratory instrument manufacturing (9 awards), and research and development support (3 awards) dominate the NAICS and PSC splits.
