The Naval Warfare Center Corona Division is conducting market research to identify potential suppliers capable of providing LGC Standards (or equivalent) VHG-PCMTD-5-500 Particle Count Verification Fluid, as described in a draft Purchase Description/Statement of Work. Interested parties are invited to submit a Capability Statement that includes company details, business size under NAICS 325199, estimated unit price and lead time, and comments on the draft requirements. The government will use the responses to determine the appropriate acquisition method, including possible small business set-asides or competitive versus non-competitive approaches. This is a sources sought notice only—not a solicitation—and does not obligate the government to award a contract or cover response preparation costs.
