DLA Troop Support Clothing & Textiles is conducting market research via a Sources Sought notice—not a solicitation—to identify U.S.-based potential sources with domestic manufacturing capabilities for Leather, Sheepskin, Hair Type, including production capacity, limitations, and challenges. The effort supports items such as helmet retention systems and seeks input on minimum quantities, monthly/weekly production rates, lead times, raw material availability, supply chain, and country of origin, with additional market research possibly conducted before any solicitation is posted. Domestic sources are required under DFARS 252.225-7002-2(c), and the applicable NAICS is 315990. Interested vendors should email the listed contract specialist and contracting officer with company information and responses to the questionnaire; SAM registration and representations/certifications are required for award eligibility. The Government will not pay for information submitted, participation is voluntary, and this notice does not commit the Government to future business.
