Freight Rail Coupler Systems and Certain Components Thereof

The scope of this investigation covers freight rail car coupler systems and certain components thereof. Freight rail car coupler systems are composed of, at minimum, four main components (knuckles, coupler bodies, coupler yokes, and follower blocks, as specified below) but may also include other items (e.g., coupler locks, lock lift assemblies, knuckle pins, knuckle throwers, and rotors). The components covered by the investigation include: (1) E coupler bodies; (2) E/F coupler bodies; (3) F coupler bodies; (4) E yokes; (5) F yokes; (6) E knuckles; (7) F knuckles; (8) E type follower blocks; and (9) F type follower blocks, as set forth by the Association of American Railroads (AAR). The freight rail coupler components are included within the scope of the investigation when imported individually, or in some combination thereof, such as in the form of a coupler fit (a coupler body and knuckle assembled together), independent from a coupler system. Subject freight rail car coupler systems and components are included within the scope whether finished or unfinished, whether imported individually or with other subject or non-subject components, whether assembled or unassembled, whether mounted or unmounted, or if joined with non-subject merchandise, such as other non-subject system parts or a completed rail car. Finishing includes, but is not limited to, arc washing, welding, grinding, shot blasting, heat treatment, machining, and assembly of various components. When a subject coupler system or subject components are mounted on or to other non-subject merchandise, such as a rail car, only the coupler system or subject components are covered by the scope. The finished products covered by the scope of this investigation meet or exceed the AAR specifications of M-211, "Foundry and Product Approval Requirements for the Manufacture of Couplers, Coupler Yokes, Knuckles, Follower Blocks, and Coupler Parts" or AAR M-215 "Coupling Systems," or other equivalent domestic or international standards (including any revisions to the standard(s)). The country of origin for subject coupler systems and components, whether fully assembled, unfinished or finished, or attached to a rail car, is the country where the subject coupler components were cast or forged. Subject merchandise includes coupler components as defined above that have been further processed or further assembled, including those coupler components attached to a rail car in third countries. Further processing includes, but is not limited to, arc washing, welding, grinding, shot blasting, heat treatment, painting, coating, priming, machining, and assembly of various components. The inclusion, attachment, joining, or assembly of non-subject components with subject components or coupler systems either in the country of manufacture of the in-scope product or in a third country does not remove the subject components or coupler systems from the scope.
