NOAA intends to award a firm-fixed-price purchase order for brand-name CHCNAV RTK GNSS hydrologic survey equipment and accessories, to be purchased through a U.S.-based reseller. The requirement is a total small business set-aside under NAICS 334220. This justification posting is not a request for competitive proposals or an invitation for price quotes. The CHCNAV equipment is exempt from the Buy American Act under the RFO, and the purchase must comply with RFO FAR 40.204-2 and Section 889 restrictions on covered telecommunications and video surveillance equipment from Huawei, ZTE, and their subsidiaries or affiliates. This acquisition is for the Department of Commerce, not the Department of Defense, so the DoD 1260H “Chinese Military Companies” banned list does not apply.
