Envigo RMS LLC

Envigo RMS LLC, operating as Harlan Laboratories, supplies laboratory research animals, animal diets, bedding materials, and specialized animal services to federal research agencies as a prime contractor competing on a full-and-open basis with no set-aside designations. The Indianapolis-headquartered vendor is a for-profit manufacturer and a subsidiary of Inotiv, Inc., with Envigo Bioproducts Inc. as a named operational division. Across 120 prime awards spanning 2011 to April 2026, Envigo has generated $135.6 million in combined potential value, obligating $3.8 million to date; the vendor operates exclusively as a prime contractor with zero subcontract awards in the source data.

Envigo's core federal capability centers on breeding and supplying barrier-raised rodents (rats, mice, hamsters, gerbils, guinea pigs), specialized research animal diets (NIH-31 formula, sterilizable diets), and animal bedding (hardwood sanichip, maple sani-chip), along with veterinary support and custom services such as hybridoma production and genetically modified animal models. Representative recent awards include a $79,469 firm-fixed-price purchase order from the National Institute of Child Health and Human Development (April 2026) for animal bedding and feed at the Castleton, Indiana facility; a $244,218 purchase order from the National Institute of Dental and Craniofacial Research (March 2025) for rodent diet and bedding through March 2029; and a $306,490 indefinite delivery contract from USDA Animal and Plant Health Inspection Service (September 2023) to supply laboratory mice for rabies vaccination testing through September 2028.

Customer concentration skews heavily toward the National Institutes of Health ecosystem and USDA. The National Institute of Environmental Health Sciences leads by award count (39 awards, $2.2 million combined potential value), followed by the USDA Agricultural Research Service Midwest Area (20 awards, $93 thousand). However, the top customers by dollars diverge sharply: the NIH Office of Logistics and Acquisition Operations anchors the portfolio at 7 awards worth $67 million in combined potential value, and the Defense Health Agency contributes 3 awards at $60 million. Together, these two customers account for roughly 93% of total potential value. The top five customer agencies represent 97% of combined potential value, indicating significant concentration risk tied to major IDV renewals.

Envigo holds multiple significant indefinite delivery vehicles anchoring task-order activity. The Defense Health Agency Blanket Purchase Agreement (awarded July 2025) carries a $35 million ceiling through July 2030 for small laboratory research animals. The NIH National Institute on Aging single-award indefinite delivery contract (January 2024) is valued at $885,277 through January 2029 and supplies feed and bedding to support an 18,000-rodent research colony. The NIH National Institute of Environmental Health Sciences holds a $300,000 single-award indefinite delivery contract (June 2024) through June 2029 for barrier-raised rodents and specialized animal services. The USDA APHIS indefinite delivery contract (September 2023) covers $306,490 through September 2028. A $1.5 million Blanket Purchase Agreement with the Uniformed Services University of the Health Sciences (August 2021) provided rodents for medical research through October 2024 and has now expired. Task order activity is concentrated in five parent vehicles: the NIEHS indefinite delivery contract (19 task orders, $243 thousand), the USDA ARS indefinite delivery contract (17 task orders, $33 thousand), and three others generating smaller cumulative volumes.

Award activity trended upward from 2022 (19 awards) through 2023 (25 awards) before moderating to 23 awards in 2024; 2025 saw only 9 awards and 2026 shows 1 award to date. Eight awards with ultimate completion dates in the next twenty-four months carry $599 thousand in combined potential value, creating moderate recompete exposure. The vendor performs across two principal NAICS categories—Other Animal Food Manufacturing (57 awards) and All Other Animal Production (41 awards)—and is correspondingly classified under PSC codes for Forage and Feed (39 awards) and Live Animals Not Raised for Food (36 awards). Major performance locations include Castleton, Indiana (primary breeding and supply facility) and Research Triangle Park, North Carolina, with secondary operations in Ames, Iowa supporting USDA Agricultural Research Service programs.
