The Indian Health Service's Kayenta Service Unit is conducting market research to identify sources capable of supplying an ultrasound unit compatible with its IT software (RPMS, EHR, and PACS). Indian-owned economic enterprises (IEE/ISBEE) will be considered first under the Buy Indian Act, but other capable firms are also invited to respond. The applicable NAICS code is 334510 with a 1,250-employee size standard, and respondents must be registered in SAM.gov at the time of award. This is not a solicitation; participation is voluntary, and the government assumes no cost responsibility. Interested parties should submit a company profile, capability statement, past performance information, and for Indian-owned firms, an IEE Representation Form.
