Circular Welded Carbon Quality Steel Line Pipe

The merchandise covered by this order is circular welded carbon quality steel pipe of a kind used for oil and gas pipelines (welded line pipe), not more than 406.4 mm (16 inches) in outside diameter, regardless of wall thickness, length, surface finish, end finish or stenciling. The term "carbon quality steel" includes both carbon steel and carbon steel mixed with small amounts of alloying elements that may exceed the individual weight limits for non alloy steels imposed in the Harmonized Tariff Schedule of the United States (HTSUS). Specifically, the term "carbon quality" includes products in which (1) iron predominates by weight over each of the other contained elements, (2) the carbon content is 2 percent or less by weight and (3) none of the elements listed below exceeds the quantity by weight respectively indicated: (i) 2.00 percent of manganese, (ii) 2.25 percent of silicon, (iii) 1.00 percent of copper, (iv) 0.50 percent of aluminum, (v) 1.25 percent of chromium, (vi) 0.30 percent of cobalt, (vii) 0.40 percent of lead, (viii) 1.25 percent of nickel, (ix) 0.30 percent of tungsten, (x) 0.012 percent of boron, (xi) 0.50 percent of molybdenum, (xii) 0.15 percent of niobium, (xiii) 0.41 percent of titanium, (xiv) 0.15 percent of vanadium, or (xv) 0.15 percent of zirconium. Welded line pipe is normally produced to specifications published by the American Petroleum Institute (API) (or comparable foreign specifications) including API A-25, 5LA, 5LB, and X grades from 42 and above, and/or any other proprietary grades or non-graded material. Nevertheless, all pipe meeting the physical description set forth above that is of a kind used in oil and gas pipelines, including all multiple-stenciled pipe with an API welded line pipe stencil is covered by the scope of this order. Excluded from this scope are pipes of a kind used for oil and gas pipelines that are multiple-stenciled to a standard and/or structural specification and have one or more of the following characteristics: is 32 feet in length or less; is less than 2.0 inches (50 mm) in outside diameter; has a galvanized and/or painted surface finish; or has a threaded and/or coupled end finish.
