12.805—Definitions.
Components, as used in this subpart, means those articles, materials, and supplies incorporated directly into construction materials.
Construction, as used in this subpart, means construction, alteration, or repair of any public building or public work in the United States.
Construction materials, as used in this subpart, means an article, material, and supply brought to the construction site for incorporation into the building or work.
Construction material also includes an item brought to the site pre-assembled from articles, materials, and supplies. However, emergency life safety systems, such as emergency lighting, fire alarm, and audio evacuation systems, which are discrete systems incorporated into a public building or work and which are produced as a complete system, shall be evaluated as a single and distinct construction material regardless of when or how the individual parts or components of such systems are delivered to the construction site.
Domestic construction material, as used in this section, means: (a) An unmanufactured construction material mined or produced in the United States, or (b) a construction material manufactured in the United States, if the cost of its components mined, produced, or manufactured in the United States exceeds 50 percent of the cost of all its components. (In determining whether a construction material is domestic, only the construction material and its components shall be considered.) The cost of each component includes transportation costs to the place of incorporation into the construction material and any applicable duty (whether or not a duty-free entry certificate is issued). Components of foreign origin of the same class or kind for which determinations have been made in accordance with § 12.810(a)(3) are treated as domestic.
Foreign construction material, as used in this section, means as construction material other than a domestic construction material.
