�Domestic end product� means� (1) An unmanufactured end product mined or produced in the United States; (2) An end product manufactured in the United States, if� (i) The cost of its components mined, produced, or manufactured in the United States exceeds 55 percent of the cost of all its components. Components of foreign origin of the same class or kind as those that the agency determines are not mined, produced, or manufactured in sufficient and reasonably available commercial quantities of a satisfactory quality are treated as domestic. Scrap generated, collected, and prepared for processing in the United States is considered domestic; or (ii) The end product is a COTS item. Note: "Assembly" may be considered "manufacturing", provided the assembly operations undertaken in the US make the item suitable for its intended use by NTESS and establish its identity. Operations performed after the item has been completed (e.g., packaging, testing) or to add a single component (e.g., one circuit) would not qualify as manufacturing.
Certification (a) The offeror certifies that each end product with an anticipated value exceeding $10,000, except those listed in paragraph (b) of this provision, is a domestic end product and that for other than COTS items, the offeror has considered components of unknown origin to have been mined, produced, or manufactured outside the United States. The offeror shall list as foreign end products those end products manufactured in the United States that do not qualify as domestic end products, i.e., an end product that is not a COTS item and does not meet the component test in paragraph (2) of the definition of �domestic end product.� The terms �commercially available off-the-shelf (COTS) item,� �component,� �domestic end product,� �end product,� �foreign end product,� and �United States� are defined in FAR 52.225-1 Buy American�Supplies. Note: For purposes of valuation against the $10,000 threshold, NTESS considers the purchase of multiples of a single item (e.g., twenty N95 masks) and bulk purchases (e.g., 1000-pc reel of capacitors) an individual item.
(b) Foreign End Products (enter N/A below, if no foreign end products will be provided):
