This is a total small-business set-aside Navy procurement for special-emphasis, Level I/SUBSAFE carbon steel bars for a critical shipboard system, manufactured to ASTM-A696 Grade C, hot-wrought, descaled, round, 4-inch size, and 8–12 ft lengths (plus/minus 10%). The contractor must maintain ISO-9001 or acceptable equivalent quality and calibration systems, provide full material traceability and certification, and comply with strict marking, handling, inspection, and certificate-of-compliance requirements. Final material delivery is scheduled at 365 days, with PNSY review/acceptance of certification CDRLs 45 working days after receipt; early and incremental delivery is acceptable at no additional cost. A 365-day warranty after acceptance applies, constructive acceptance under prompt payment is 45 days after delivery, past performance will be evaluated, and the procurement is issued under Emergency Acquisition Flexibilities. There is no Government source inspection; inspection and acceptance occur at destination/destination.
