Customs Standards

The FDA Denver Human and Animal Food Laboratory (DENHAFL) is conducting market research through a Sources Sought Notice due August 7, 2026, to identify suppliers of custom-prepared, multi-component analytical reference standard solutions for regulatory analysis of veterinary drug residues in aquaculture, dairy, and game-meat products. The FDA has not yet committed to a formal solicitation and is assessing market capacity and small business availability to determine set-aside feasibility.

Respondents must be ISO 17034–accredited and certified. Standards must support initial and continuing calibration verification in liquid chromatography-mass spectrometry methods, delivered in 1 mL glass ampules dissolved in LC-MS-grade solvents. The requirement spans approximately 150 ampules across 30 line items, organized into 15 distinct multi-component mixtures by drug class (NSAIDs, macrolides, amphenicols, avermectins, nitroimidazoles, quinolones, fluoroquinolones, sulfonamides). Each mixture requires two separate lots—Lot A (five ampules for ICV) and Lot B (five ampules for CCV). Standards must maintain a minimum 12-month shelf-life from shipment; standards with certified shelf-life less than 12 months require replacement ampules at no additional cost approximately 165 days after first shipment.

Delivery is required on or about December 1, 2026, to FDA Denver Laboratory (6th Avenue & Kipling Street, Building 20, Door W10, Denver, Colorado 80225). Period of performance is one year from contract award. Each standard batch must include a Certificate of Analysis documenting component names, lot numbers, CAS numbers, uncertainty levels, expiration dates, solvents, and certified values.

NAICS 325998 (500-employee size standard); PSC 6810. Responses must include a completed Vendor Response Form in native Microsoft Excel format and a capability statement not exceeding five pages. Mail responses to David.Seid@FDA.HHS.Gov by August 7, 2026, at noon ET.
