Customs Standards

The FDA Denver Human and Animal Food Laboratory is seeking custom-prepared, multi-component analytical reference standard solutions to support the regulatory analysis of veterinary drug residues in aquaculture, dairy, and game-meat products. These standards are critical for initial and continuing calibration verification in liquid chromatography–mass spectrometry methods used for screening and confirmatory testing. The requirements specify that the standards must be precisely formulated to meet the lab’s analytical protocols, ensuring accuracy and reliability in detecting and quantifying drug residues at low concentrations. The solutions will be used in compliance with federal food safety regulations to safeguard public health and ensure the integrity of the food supply chain. Solicitation number HPF-2026-135452 was posted on August 4, 2026, with responses due by August 7, 2026, at 4:00 p.m. Eastern Time. This is a sources-sought notice under NAICS code 325998, with no set-aside provisions applied. The contract is managed by the FDA Office of Acquisition and Grant Services under the Department of Health and Human Services, located in Rockville, Maryland, but the performance location is the Denver laboratory in Colorado. The primary point of contact for inquiries is David Seid, reachable via email or phone, and additional details can be found through the provided SAM.gov link. All proposals must demonstrate technical capability to deliver high-purity, stable, and certified reference standards meeting strict regulatory standards for analytical use.
