Envigo RMS LLC

Envigo RMS LLC, doing business as Harlan Laboratories, supplies laboratory research animals (barrier-raised rodents including rats, mice, hamsters, gerbils, and guinea pigs), specialized animal diets, bedding materials, and veterinary support services to federal research agencies as a prime contractor on a full-and-open, non-set-aside basis. The company is a for-profit manufacturer and subsidiary of Inotiv, Inc., headquartered in Indianapolis, Indiana, with operational facilities in Castleton, Indiana; Research Triangle Park, North Carolina; and Ames, Iowa.

Envigo RMS LLC's federal customer base is concentrated in the research infrastructure agencies. The top five funding organizations by combined potential value account for 96% of the portfolio: the National Institutes of Health's Office of Logistics and Acquisition Operations (7 awards, $67 million combined potential value, dominated by a $35 million Defense Health Agency blanket purchase agreement awarded July 9, 2025 for small laboratory research animals through July 8, 2030); the Defense Health Agency (3 awards, $60 million); the National Institute of Environmental Health Sciences (40 awards, $2.2 million, the most frequent customer by award count); the Veterans Health Administration's Veterans Integrated Service Network 4 (2 awards, $701 thousand); and the National Institute on Aging (4 awards, $509 thousand). The portfolio spans 24 distinct federal customer agencies, including the National Institutes of Health components, the Department of Agriculture (Agricultural Research Service, Animal and Plant Health Inspection Service, Veterinary Services), the Food and Drug Administration, the Centers for Disease Control and Prevention, and the Department of Veterans Affairs. Award concentration by count versus dollar value reveals a two-tier customer pattern: the NIEHS issues frequent small orders (40 awards averaging $55 thousand each), while the Defense Health Agency and NIH's Office of Logistics anchors the largest dollar commitments through multi-million-dollar blanket purchase agreements and single-award IDCs.

Envigo RMS LLC holds four major indefinite delivery vehicles: a $35 million blanket purchase agreement with the Defense Health Agency for small laboratory research animals (awarded July 2025, running through July 2030); an $885.3 thousand single-award indefinite delivery contract with the National Institute on Aging for feed and bedding supplies (awarded January 2024, ultimate completion January 2029); a $650 thousand single-award indefinite delivery contract with the National Institute of Environmental Health Sciences for animal bedding (awarded June 2022, running through June 2027); and a $306.5 thousand single-award indefinite delivery indefinite quantity contract with the USDA Animal and Plant Health Inspection Service for laboratory mice in support of rabies vaccination testing (awarded September 2023, completion September 2028). The NIEHS animal bedding vehicle carries documented task orders worth approximately $243 thousand across 19 orders, with individual delivery orders ranging from $10.7 thousand to $37.8 thousand per shipment. Recent activity shows two award issuances in 2026 (both in August, totaling $162.2 thousand for VISN 21 animal bedding and feed and NICHD rodent feed and bedding) against a portfolio that peaked at 25 awards in 2023 and has moderated to 9 awards in 2025 and 2 in 2026 year to date.

Representative transactional work includes a $244.2 thousand firm-fixed-price purchase order with the National Institute of Dental and Craniofacial Research (awarded March 2025, performance through March 2029) for rodent diet and bedding; a $176.5 thousand delivery order with the National Institute on Aging (awarded January 2024, performance through January 2029) for animal feed and bedding for the agency's Intramural Research Program colony; a $108 thousand standing order with the National Institute of Child Health and Human Development (awarded July 2023, performance through July 2024) for approximately 4,166 kilograms of NIH-31 mouse and rat sterilizable diet plus maple sani chip bedding on a weekly basis; and a $81.9 thousand firm-fixed-price purchase order with the National Institute on Alcohol Abuse and Alcoholism (awarded February 2025, completion February 2026) for rat sterilizable diet and bedding on weekly or bi-weekly delivery schedule. Specialized research animal work includes a $57.7 thousand five-year delivery order with the USDA Animal and Plant Health Inspection Service (awarded October 2024, completion September 2028) for 8,000 CF-1 mice per fiscal year to support NIH rabies testing, and a $46 thousand delivery order with USDA Veterinary Services (awarded September 2023, completion September 2028) for laboratory mice (Swiss Webster and CF-1 strains) delivered to Ames, Iowa.

Awards per year data shows sustained volume from 2022 through 2024 (20 to 25 awards annually) with a sharp reduction in 2025 and 2026 (9 and 2 awards respectively), signaling either a shift in ordering patterns across the large IDCs or a possible decline in transactional purchase orders. Twelve awards carrying combined potential value of $873 thousand face ultimate completion dates within the next twenty-four months, representing the recompete and renewal exposure window. The portfolio reflects a commodity-like business model: 58 of 122 awards are classified under NAICS 424410 (Other Animal Food Manufacturing), 41 under 311611 (All Other Animal Production), and 21 under 321999 (All Other Miscellaneous Wood Product Manufacturing for bedding). Nearly all awards are firm-fixed-price purchase orders or delivery orders issued off single-award or multiple-award indefinite delivery vehicles with no socioeconomic set-aside designations, indicating Envigo RMS LLC competes exclusively on full-and-open basis and has no small-business, minority-owned, or other special-status certification in the federal portfolio.

Envigo RMS LLC operates as a subsidiary of Inotiv, Inc. (a for-profit manufacturer with federal prime contract and grant-award history). A subsidiary entity, Envigo Bioproducts Inc., appears on several delivery order awards as an alternate vendor name or organizational reference. Corporate documentation identifies Envigo RMS Holding Corp. as the parent of Envigo RMS LLC in some contract narratives, though SAM.gov structure records show Inotiv, Inc. as the parent organization. The vendor's federal market position rests on specialized breeding and husbandry capability for regulated laboratory animal strains and the ability to supply consistent, high-quality bedding and diet formulations that meet federal research standards—capabilities that support sole-source or restricted-competition awards when particular animal strains or product certifications are required.
