About GC3 Specialty Chemicals Inc.
GC3 Specialty Chemicals Inc., a minority-owned, woman-owned small business headquartered in Houston, Texas, manufactures and supplies aqueous ammonia and specialty inorganic chemicals to the federal government as a prime contractor (100% of recent awards) operating predominately on indefinite delivery contracts and delivery orders under total small business and competitive (non-set-aside) designations.
GC3's customer footprint is heavily concentrated with the U.S. Army Corps of Engineers. The Engineering District Baltimore and Engineering District Norfolk together account for 40 awards (87% of the total) and $9.9 million in combined potential value (87% of the portfolio). The Washington Aqueduct, a subordinate component within the Baltimore District's area of responsibility, contributes an additional $1.4 million in combined potential value across four awards. The remaining exposure sits with the Department of the Army and the Air Force Materiel Command Air Force Sustainment Center. The vendor operates exclusively through indefinite delivery contracts, with four parent vehicles anchoring the footprint: IDC W912DR18D0020 (14 task orders, $1.6 million), W912DR23D0016 (4 task orders, $1.1 million), W9123612D0020 (19 task orders, $398 thousand), and W912DR25D0015 (2 task orders, $731 thousand).
GC3's primary capability is the manufacture and delivery of aqueous ammonia 19% solution for municipal water treatment pH regulation, classified under NAICS 325180 (Other Basic Inorganic Chemical Manufacturing) and PSC 6810 (Chemicals). Representative work includes a $430 thousand total small business delivery order issued February 27, 2026, for aqua ammonia supply to the Washington Aqueduct with completion targeted July 31, 2026; a $301 thousand non-set-aside delivery order awarded August 1, 2025, supporting the same customer; and a $474.7 thousand delivery order awarded June 23, 2022, to supply the Dalecarlia Water Treatment Plant. GC3 has demonstrated sustained performance as a qualified supplier since at least 2021, with prior individual delivery orders ranging from $157 thousand to $474.7 thousand. The vendor currently operates under a $2.193 million total small business indefinite delivery contract awarded August 1, 2025, running through July 31, 2028, and under a predecessor $1.462 million non-set-aside indefinite delivery contract that expired July 18, 2025.
Award activity has remained relatively flat—two to three awards per year over the past five years—with combined potential value of $11.3 million and $4.5 million in actual obligations (40% of potential). Only two awards totaling $731 thousand face ultimate completion within the next twenty-four months, creating minimal recompete pressure in that window. GC3 competes and performs exclusively as a prime contractor; there are no subcontract relationships in the source data.
