The merchandise under consideration, which you describe as a Cliplock 1000 Roof Curb, is a raised metal frame with a factory installed wood nailer strip. The frame is manufactured of galvanized steel, but could also be constructed of stainless steel or aluminum. The frame is 3 ½ inches wide by 3 ½ inches long. It is 1 ¾ inches thick. It has a bottom projecting flat rim that is 1 ¾ inches wide. The frame comes in custom or optional 14, 18 or 24 inch heights. There is a wood nailer strip along the outside top edge of all 4 sides that is 2 inches wide by 3 inches long. You state the purpose of the frame is to mount mechanical units to a roof. We disagree with your proposed classification of 7326.90.8688, Harmonized Tariff Schedule of the United States (HTSUS), which provides for Other articles of iron or steel, Other, Other, Other, Other, Other. The Explanatory Notes to heading 73.26 state that “This heading covers all iron or steel articles… other than articles included in Chapter 82 or 83 or more specifically covered elsewhere in the Nomenclature.” The roof curb under consideration is not classifiable in heading 7326, HTSUS, because it is more specifically provided for in Chapter 83, HTSUS. The applicable subheading for the roof curb will be 8302.41.6080, HTSUS, which provides for Base metal mountings, fittings and similar articles suitable for furniture, doors, staircases, windows, blinds coachwork….Suitable for buildings; Other; Of iron or steel, of aluminum or of zinc; Other. The rate of duty will be 3.9% ad valorem. Duty rates are provided for your convenience and are subject to change.
