Capitol Carbonic Corp

Capitol Carbonic Corp, operating as the Capitol Carbonic Corporation Division, manufactures and supplies dry ice and cryogenic products to federal agencies as a prime contractor on firm fixed-price delivery orders and indefinite delivery contracts, competing on a full-and-open basis with no set-aside designations. The Catonsville, Maryland-based for-profit Subchapter S corporation is classified under NAICS 327910 (Ice Manufacturing) and PSC 6830 (Gases: Compressed and Liquefied), and has served 23 distinct federal agencies across 356 prime awards over the past five years, with combined potential value of $91.7 million and $17.8 million in obligated dollars.

Capitol Carbonic's customer concentration centers overwhelmingly on the National Institutes of Health. The top three NIH offices account for 77% of recent award volume and 87% of combined potential value: the Office of Logistics and Acquisition Operations leads with 124 awards valued at $25.2 million combined, the Office of the Director holds 89 awards worth $37.8 million, and the main NIH entity carries 27 awards at $14.7 million. Secondary customers include the Department of the Army (22 awards), the Department of the Air Force (4 awards, $1.3 million), and the National Institute on Aging (4 awards, $1.1 million). The dollars-versus-volume split tracks tightly across the top NIH offices, indicating steady, recurring demand rather than a few large anchoring contracts at one bureau level.

Capitol Carbonic holds position on five named indefinite delivery vehicles, all single-award IDIQs issued by NIH or DoD. The primary vehicle is Indefinite Delivery Contract 75N98022D00017, carrying 47 task orders valued at $4.9 million combined and running through May 31, 2027 with a $7.3 million ceiling; this contract anchors Capitol Carbonic's relationship with NIH's Office of Logistics and Acquisition Operations and has generated steady monthly delivery orders for dry ice pellets, blocks, and slabs since June 2022. Three additional older NIH IDIQs (HHSN263200600004I, valued at $35.3 million across 61 task orders; HHSN263201200001I, at $2.4 million across 62 task orders; and HHSN263201700003I, at $3 million across 66 task orders) reflect historical consolidation and demonstrate Capitol Carbonic's multi-decade tenure as NIH's primary dry ice supplier. A Defense Health Agency IDIQ valued at $120,800 supports the U.S. Army Medical Research Institute of Infectious Diseases at Fort Detrick, Maryland.

Recent awards span both recurring operational replenishment and mission-specific biomedical work. Representative contracts include a $792,792 firm fixed-price purchase order from the National Institute on Aging (March 2023, extending through March 2028) for dry ice pellets supporting the NIA Intramural Research Program; a $419,250 Total Small Business purchase order from the Air Force 89th Aerial Port Squadron at Joint Base Andrews (September 2025, extending through September 2030) for weekly 4,000-pound dry ice block deliveries to maintain temperature-sensitive cargo for air transport missions; a $403,416 FDA purchase order (January 2025, extending through January 2030) for weekly dry ice deliveries to the Center for Biologics Evaluation and Research in Silver Spring, Maryland; and a $366,504 delivery order from NIH's Office of Logistics and Acquisition Operations (June 2026, completion October 2026) for ongoing lab and office support.

Activity has declined sharply in recent years. The vendor recorded 49 awards in 2022, then dropped to one award per year in 2023 and 2024, with three awards in both 2025 and 2026. This trajectory suggests maturation of a long-standing supply relationship into stable, low-volume replenishment ordering. Only six awards with ultimate completion dates in the next twenty-four months carry combined potential value of $1.5 million, indicating minimal near-term recompete exposure; most legacy IDIQs have expired or are fully obligated, and the 75N98022D00017 vehicle does not expire until May 2027.

Capitol Carbonic competes exclusively as a prime on full-and-open contracts without set-aside protections, relying on an established federal supplier presence and manufacturing proximity to NIH and other research facilities in the Maryland-Washington region. The vendor holds no subcontracting relationships in the source data and generates no sub-award revenue. The concentrated NIH customer base, stable but declining ordering volume, and single-product-line posture (dry ice in pellet, block, and slab form) reflect a specialized supplier model with deep institutional relationships but limited pathway to growth outside cryogenic logistics for federal research operations.
