Daijin Co.,Ltd.

Daijin Co.,Ltd., a Japanese for-profit corporation headquartered in Yokosuka, Kanagawa Prefecture, manufactures and supplies specialized industrial catalyst products to the U.S. Navy as a prime contractor under full-and-open (unrestricted) competition, with 100% of recent awards structured as delivery orders issued against single-award indefinite delivery contracts held with Naval Facilities Engineering Command.

Daijin's federal portfolio is narrowly concentrated on a single customer agency and a single product line. The Department of the Navy's Naval Facilities Engineering Command accounts for 166 of 169 total awards (98% of award count) and $4.5 million of $4.6 million combined potential value (98%). The remaining three awards and $40 thousand derive from the Department of the Navy's Naval Sea Systems Command. Daijin supplies two proprietary catalyst formulations — Catalyst Takuron and Catalyst Takuron PX — used in incineration plants and waste disposal facilities at U.S. Navy installations in the Pacific region, primarily in Japan. All work is performed in Japan, and the company operates exclusively as a prime contractor with no subcontractor relationships in the federal portfolio.

Daijin's vehicle position consists of five active single-award indefinite delivery contracts with NAVFAC, each providing a ceiling and umbrella framework for firm fixed price delivery orders issued as operational requirements arise. The largest vehicles by task-order count are Indefinite Delivery Contract N6264916D0005 (61 task orders, $583 thousand combined potential value) and N6264919D0012 (48 task orders, $613 thousand combined potential value), both now closed or in final delivery phases. The most recent active IDC, awarded March 12, 2026, carries a $268,498 ceiling through May 12, 2028; the previous active contract, awarded May 13, 2025, held $218,862 through May 12, 2026. Delivery orders under these vehicles typically range from $8,000 to $32,760 per order and carry firm fixed price terms with completion dates 30–90 days from issuance.

Activity has remained modest and flat, averaging 11–15 awards per year over the past five years. The source reflects 169 total awards spanning from September 8, 2009 to April 9, 2026, with 44% of combined potential value ($2 million) obligated across all awards. Daijin maintains an exclusive supplier relationship with NAVFAC dating to at least 2007, when the company first registered in SAM.gov. The narrow customer base and single-vendor dependence on specialized catalyst products create recompete exposure as existing IDCs mature; the March 2026 IDC represents Daijin's latest contract award and extends the relationship through mid-2028. NAICS coding reflects the product nature: 92 awards fall under All Other Miscellaneous Chemical Product and Preparation Manufacturing, 62 under Other Chemical and Allied Products Merchant Wholesalers, and 11 under Other Basic Inorganic Chemical Manufacturing.
