CSMS # 64529547 - Initiation of Antidumping and Countervailing Duty Investigations: Certain Chassis and Subassemblies Thereof from Mexico, Thailand, and the Socialist Republic of Vietnam (Vietnam) U.S. Customs and Border Protection sent this bulletin at 03/25/2025 12:22 PM EDT   Cargo Systems Messaging Service CSMS # 64529547 - Initiation of Antidumping and Countervailing Duty Investigations: Certain Chassis and Subassemblies Thereof from Mexico, Thailand, and the Socialist Republic of Vietnam (Vietnam) On March 18, 2025, the Department of Commerce (Commerce) initiated its less-than-fair-value and countervailing duty investigations on “Certain Chassis and Subassemblies Thereof from Mexico, Thailand, and Vietnam” (Initiation Notices). These investigations have been assigned the following case numbers: A-201-865 and C-201-866 (Mexico), A-549-854 and C-549-855 (Thailand), and A-522-849 (Vietnam). The Scope of Merchandise covered by these investigations reads as follows : The merchandise covered by these investigations consists of chassis and subassemblies thereof, whether finished or unfinished, whether assembled or unassembled, whether coated or uncoated, regardless of the number of axles, for carriage of containers, or other payloads (including self-supporting payloads) for road, marine roll-on/roll-off (RORO) and/or rail transport.  Chassis are typically, but are not limited to, rectangular framed trailers with a suspension and axle system, wheels and tires, brakes, a lighting and electrical system, a coupling for towing behind a truck tractor, and a locking system or systems to secure the shipping container or containers to the chassis using twist-locks, slide pins or similar attachment devices to engage the corner fittings on the container or other payload. Subject merchandise includes, but is not limited to, the following subassemblies: Chassis frames, or sections of chassis frames, including kingpin assemblies, bolsters consisting of transverse beams with locking or support mechanisms, goosenecks, drop assemblies, extension mechanisms and/or rear impact guards; Running gear assemblies or axle assemblies for connection to the chassis frame, whether fixed in nature or capable of sliding fore and aft or lifting up and lowering down, which may or may not include suspension(s) (mechanical or pneumatic), wheel end components, slack adjusters, dressed axles, brake chambers, locking pins, and tires and wheels; and Assemblies that connect to the chassis frame or a section of the chassis frame, such as but not limited to, pintle hooks or B-trains (which include a fifth wheel), which are capable of connecting a chassis to a converter dolly or another chassis. Importation of any of these subassemblies, whether assembled or unassembled, constitutes an unfinished chassis for purposes of these investigations.  Subject merchandise also includes chassis, whether finished or unfinished, entered with components such as, but not limited to hub and drum assemblies, brake assemblies (either drum or disc), bare axles, brake chambers, suspensions and suspension components, wheel end components, landing gear legs, spoke or disc wheels, tires, brake control systems, electrical harnesses and lighting systems. Processing of finished and unfinished chassis and components such as trimming, cutting, grinding, notching, punching, drilling, painting, coating, staining, finishing, assembly, or any other processing either in the country of manufacture of the in-scope product or in a third country does not remove the product from the scope. Inclusion of other components not identified as comprising the finished or unfinished chassis does not remove the product from the scope. Individual components entered and sold by themselves are not subject to the investigations, but components entered with a finished or unfinished chassis are subject merchandise. A finished chassis is ultimately comprised of several different types of subassemblies. Within each subassembly there are numerous components that comprise a given subassembly. This scope excludes dry van trailers, refrigerated van trailers and flatbed trailers. Dry van trailers are trailers with a wholly enclosed cargo space comprised of fixed sides, nose, floor and roof, with articulated panels (doors) across the rear and occasionally at selected places on the sides, with the cargo space being permanently incorporated in the trailer itself. Refrigerated van trailers are trailers with a wholly enclosed cargo space comprised of fixed sides, nose, floor and roof, with articulated panels (doors) across the rear and occasionally at selected places on the sides, with the cargo space being permanently incorporated in the trailer and being insulated, possessing specific thermal properties intended for use with self-contained refrigeration systems.  Flatbed (or platform) trailers consist of load carrying main frames and a solid, flat or stepped loading deck or floor permanently incorporated with and supported by frame rails and cross members. The finished and unfinished chassis subject to these investigations are typically classified in the Harmonized Tariff Schedule of the United States (HTSUS) at subheadings: 8716.39.0090 and 8716.90.5060. Imports of finished and unfinished chassis may also enter under HTSUS subheading 8716.90.5010. While the HTSUS subheadings are provided for convenience and customs purposes, the written description of the merchandise under investigation is dispositive. Parties may submit comments on the scope of the investigations. Please be sure to comply with all requirements pertaining submitting comments as described in the forthcoming Initiation Notices. Upon their publication in the Federal Register, the Initiation Notices may be found at www.federalregister.gov via the search bar using the case numbers assigned to these investigations. Importers should be aware that entries of subject merchandise made after the initiation of an investigation may retroactively be subject to antidumping and/or countervailing duties.
