For the purpose of these orders, the products covered are all seamless circular refined copper pipes and tubes, including redraw hollows, greater than or equal to 6 inches (152.4 mm) in length and measuring less than 12.130 inches (308.102 mm) (actual) in outside diameter ("OD"), regardless of wall thickness, bore (e.g., smooth, enhanced with inner grooves or ridges), manufacturing process (e.g., hot finished, cold-drawn, annealed), outer surface (e.g., plain or enhanced with grooves, ridges, fins, or gills), end finish (e.g., plain end, swaged end, flared end, expanded end, crimped end, threaded), coating (e.g., plastic, paint), insulation, attachments (e.g., plain, capped, plugged, with compression or other fitting), or physical configuration (e.g., straight, coiled, bent, wound on spools). The scope of these orders covers, but is not limited to, seamless refined copper pipe and tube produced or comparable to the American Society for Testing and Materials ("ASTM") ASTM-B42, ASTM-B68, ASTM-B75, ASTM-B88, ASTM-B88M, ASTM-B188, ASTM-B251, ASTM-B251M, ASTM-B280, ASTM-B302, ASTM-B306, ASTM-B359, ASTM-B743, ASTM-B819, and ASTM-B903 specifications and meeting the physical parameters described therein. Also included within the scope of these orders are all sets of covered products, including "line sets" of seamless refined copper tubes (with or without fittings or insulation) suitable for connecting an outdoor air conditioner or heat pump to an indoor evaporator unit. The phrase "all sets of covered products" denotes any combination of items put up for sale that is comprised of merchandise subject to the scope. "Refined copper" is defined as: (1) Metal containing at least 99.85 percent by weight of copper; or (2) metal containing at least 97.5 percent by weight of copper, provided that the content by weight of any other element does not exceed specified limits. Excluded from the scope of these orders are all seamless circular hollows of refined copper less than 12 inches in length whose OD (actual) exceeds its length.
