|The products subject to this investigation are certain welded stainess steel butt-weld pipe fittings ("pipe fittings"), whether finished or unfinished, under 14 inches inside diameter.|
Pipe fittings are used to connect pipe sections in piping systems where conditions require welded connections. The subject merchandise can be used where one or more of the following conditions is a factor in designing the piping system: (1) Corrosion of the piping system will occur if material other than stainless steel is used; (2) contamination of the material in the system by the system itself must be prevented; (3) high temperatures are present; (4) extreme low temperatures are present; (5) high pressures are contained within the system.
Pipe fittings come in a variety of shapes, and the following five are the most basic: "elbows", "tees", "reducers", "stub ends", and "caps". The edges of finished fittings are beveled. Threaded, grooved, and bolted fittings are excluded from this investigation. The pipe fittings subject to this investigation are classifiable under subheading 7307.23.00 of the Harmonized Tariff Schedule of the United States (HTSUS).
Although the HTSUS subheading is provided for convenience and customs purposes, our written description of the scope of this proceeding is dispositive.
