On August 16, 2017, the Coalition of American Flange Producers, composed of Core Pipe Products, Inc. and Maass Flange Corporation, filed a petition for the imposition of antidumping duties and countervailing duties on imports of Stainless Steel Flanges from the People’s Republic of China and India.


The products covered by this investigation are certain forged stainless steel flanges, whether unfinished, semi-finished, or finished, generally manufactured to the material specification of ASTM/ASME A/SA182, and made in alloys such as, but not limited to, 304, 304L, 316, and 316L (or combinations thereof). The scope includes six general types of flanges. They are: (1) weld neck, used in butt-weld line connection; (2) threaded, used for threaded line connections; (3) slip-on, used to slide over pipe; (4) lap joint, used with stub-ends/butt-weld line connections; (5) socket weld, used to fit pipe into a machine recession; and (6) blind, used to seal off a line. The sizes and descriptions of the flanges within the scope include all pressure classes of ASME B16.5 and range from one-half inch to twenty-four inches nominal pipe size. Specifically excluded from the scope of these orders are cast stainless steel flanges. Cast stainless steel flanges generally are manufactured to specification ASTM A3 51.

Unfinished stainless steel flanges possess the approximate shape of finished stainless steel flanges and have not yet been machined to final specification after the initial casting, forging, or like operations. These machining processes may include boring, facing, spot facing, drilling, tapering, threading, beveling, heating, or compressing.

The country of origin for certain forged stainless steel flanges, whether unfinished, semi-finished, or finished is the country where the flange was forged. Subject merchandise includes stainless steel flanges as defined above that have been further processed in a third country, including but not limited to processing such as boring, facing, spot facing, drilling, tapering, threading, beveling, heating, or compressing, or any other processing that would not otherwise remove the merchandise from the scope of the investigations if performed in the country of manufacture of the stainless steel flanges.

Merchandise subject to the investigation is typically imported under headings 7307.21.1000 and 7307.21.5000 of the Harmonized Tariff Schedule of the United States (HTS). While HTS subheadings are provided for convenience and customs purposes, the written description of the scope is dispositive.
