The merchandise covered by this order is welded carbon-quality steel pipes and tube, of circular cross-section, with an outside diameter (O.D.) not more than nominal 16 inches (406.4 mm), regardless of wall thickness, surface finish (e.g., black, galvanized, or painted), end finish (plain end, beveled end, grooved, threaded, or threaded and coupled), or industry specification (e.g., American Society for Testing and Materials International (ASTM), proprietary, or other), generally known as standard pipe, fence pipe and tube, sprinkler pipe, and structural pipe (although subject product may also be referred to as mechanical tubing).
Specifically, the term "carbon quality" includes products in which:
(a) iron predominates, by weight, over each of the other contained elements;
(b) the carbon content is 2 percent or less, by weight; and
(c) none of the elements listed below exceeds the quantity, by weight, as indicated:
(i) 1.80 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) 0.15 percent of molybdenum;
(xi) 0.10 percent of niobium;
(xii) 0.41 percent of titanium;
(xiii) 0.15 percent of vanadium; or
(xiv) 0.15 percent of zirconium.
Covered products are generally made to standard O.D. and wall thickness combinations. Pipe multi-stenciled to a standard and/or structural specification and to other specifications, such as American Petroleum Institute (API) API-5L specification, may also be covered by the scope of these investigations. In particular, such multi-stenciled merchandise is covered when it meets the physical description set forth above, and also has 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 (e.g., polyester coated)
surface finish; or has a threaded and/or coupled end finish.
Standard pipe is ordinarily made to ASTM specifications A53, A135, and A795, but can also be made to other specifications. Structural pipe is made primarily to ASTM specifications A252 and A500. Standard and structural pipe may also be produced to proprietary specifications rather than to industry specifications.
Sprinkler pipe is designed for sprinkler fire suppression systems and may be made to industry specifications such as ASTM A53 or to proprietary specifications.
Fence tubing is included in the scope regardless of certification to a specification listed in the exclusions below, and can also be made to the ASTM A513 specification. Products that meet the physical description set forth above but are made to the following nominal outside diameter and wall thickness combinations, which are recognized by the industry as typical for fence tubing, are included despite being certified to ASTM mechanical tubing specifications:

The scope of this order does not include:
(a) pipe suitable for use in boilers, superheaters, heat exchangers, refining furnaces and feedwater heaters, whether or not cold drawn, which are defined by standards such as ASTM A178 or ASTM A192;
(b) finished electrical conduit, i.e., Electrical Rigid Steel Conduit (also known as Electrical Rigid Metal Conduit and Electrical Rigid Metal Steel Conduit), Finished Electrical Metallic Tubing, and Electrical Intermediate Metal Conduit, which are defined by specifications such as American National Standard (ANSI) C80.1-2005, ANSI C80.3-2005, or ANSI C80.6-2005, and Underwriters Laboratories Inc.
