1. On 05/07/2024, Commerce published in the Federal Register its affirmative preliminary determination of sales at less than fair value and postponement of the final determination in the antidumping duty investigation of aluminum extrusions from Taiwan (89 FR 38080). 2. The merchandise covered by this investigation has changed. The merchandise subject to this investigation are aluminum extrusions, regardless of form, finishing, or fabrication, whether assembled with other parts or unassembled, whether coated, painted, anodized, or thermally improved. Aluminum extrusions are shapes and forms, produced by an extrusion process, made from aluminum alloys having metallic elements corresponding to the alloy series designations published by the Aluminum Association commencing with the numbers 1, 3, and 6 (or proprietary equivalents or other certifying body equivalents). Specifically, subject aluminum extrusions made from an aluminum alloy with an Aluminum Association series designation commencing with the number 1 contain not less than 99 percent aluminum by weight. Subject aluminum extrusions made from an aluminum alloy with an Aluminum Association series designation commencing with the number 3 contain manganese as the major alloying element, with manganese accounting for not more than 3.0 percent of total materials by weight. Subject aluminum extrusions made from an aluminum alloy with an Aluminum Association series designation commencing with the number 6 contain magnesium and silicon as the major alloying elements, with magnesium accounting for at least 0.1 percent but not more than 2.0 percent of total materials by weight, and silicon accounting for at least 0.1 percent but not more than 3.0 percent of total materials by weight. The scope also includes merchandise made from an aluminum alloy with an Aluminum Association series designation commencing with the number 5 (or proprietary equivalents or other certifying body equivalents) that have a magnesium content accounting for up to but not more than 2.0 percent of total materials by weight. The country of origin of the aluminum extrusion is determined by where the metal is extruded (i.e., pressed through a die). Aluminum extrusions are produced and imported in a wide variety of shapes and forms, including, but not limited to, hollow profiles, other solid profiles, pipes, tubes, bars, and rods. Aluminum extrusions that are drawn subsequent to extrusion (drawn aluminum) are also included in the scope. Subject aluminum extrusions are produced and imported with a variety of coatings and surface treatments, and types of fabrication. The types of coatings and treatments applied to aluminum extrusions include, but are not limited to, extrusions that are mill finished (i.e., without any coating or further finishing), brushed, buffed, polished, anodized (including bright dip), liquid painted, electroplated, chromate converted, powder coated, sublimated, wrapped, and/or bead blasted. Subject aluminum extrusions may also be fabricated, i.e., prepared for assembly, or thermally improved. Such operations would include, but are not limited to, extrusions that are cut-to-length, machined, drilled, punched, notched, bent, stretched, stretch-formed, hydroformed, knurled, swedged, mitered, chamfered, threaded, spun, etched, and engraved. Performing such operations in third countries does not otherwise remove the merchandise from the scope of the investigations. The types of products that meet the definition of subject merchandise include but are not limited to, the aluminum extrusion portions of vehicle roof rails and sun/moon roof framing, solar panel racking rails and framing, tradeshow display fixtures and framing, parts for tents or clear span structures, fence posts, drapery rails or rods, electrical conduits, door thresholds, flooring trim, electric vehicle battery trays, heat sinks, signage or advertising poles, telescoping poles, or cleaning system components. Aluminum extrusions may be heat sinks, which are fabricated aluminum extrusions that dissipate heat away from a heat source and may serve other functions, such as structural functions. Heat sinks come in a variety of sizes and shapes, including but not limited to a flat electronic heat sink, which is a solid aluminum extrusion with at least one flat side used to mount electronic or mechanical devices; a heat sink that is a housing for electronic controls or motors; lighting heat sinks, which dissipate heat away from LED devices; and process and exchange heat sinks, which are tube extrusions with fins or plates used to hold radiator tubing. Heat sinks are included in the scope, regardless of whether the design and production of the heat sinks are organized around meeting specified thermal performance requirements and regardless of whether they have been tested to comply with such requirements. For purposes of the investigations on aluminum extrusions from the People's Republic of China, only heat sinks designed and produced around meeting specified thermal performance requirements and tested to comply with such requirements are included in the scope. Excluded from the scope of the investigations are large, multi-finned extruded aluminum heat sinks designed to dissipate heat, meeting the following criteria: (1) an aspect ratio (defined as the ratio of the area of a void in an extrusion to the size of the smallest gap opening at the entrance of that void and calculated by dividing the void area by the square of the gap opening) greater than 15 to 1; or (2) the circumscribing circle diameter (defined as the diameter of the smallest circle that will entirely enclose the extrusion's cross-sectional profile) rounded up to the next half inch, exceeds 10 inches, and the weight-per-foot (defined as the theoretical weight of the profile as extruded prior to any machining that may remove material and calculated by multiplying the area of the profile in square inches by 1.2) exceeds 3.50 pounds per foot. Merchandise that is comprised solely of aluminum extrusions or aluminum extrusions and fasteners, whether assembled at the time of importation or unassembled, is covered by the scope in its entirety. The scope also includes aluminum extrusions contained in merchandise that is a part or subassembly of a larger whole, whether or not the merchandise also contains a component other than aluminum extrusions that is beyond a fastener. Such merchandise may be either assembled or unassembled at the time of importation. A "part or subassembly" is defined as a unit designed to be attached to, or incorporated with, one or more other units or components into a larger completed product. Only the aluminum extrusion portion of the merchandise described in this paragraph, whether assembled or unassembled, is subject merchandise included in the scope and subject to duties. Examples of merchandise that is a part or subassembly of a larger whole include, but are not limited to, window parts or subassemblies; door unit parts or subassemblies; shower and bath parts or subassemblies; solar panel mounting systems; fenestration system parts or subassemblies, such as curtain wall and window wall units and parts or subassemblies of storefronts; furniture parts or subassemblies; appliance parts or subassemblies, such as fin evaporator coils and systems for refrigerators; railing or deck system parts or subassemblies; fence system parts or subassemblies; motor vehicle parts or subassemblies, such as bumpers for motor vehicles; trailer parts or subassemblies, such as side walls, flooring, and roofings; electric vehicle charging station parts or subassemblies; or signage or advertising system parts or subassemblies. Parts or subassemblies described by this paragraph that are subject to duties in their entirety pursuant to existing antidumping and countervailing duty orders (defined as those antidumping and countervailing duty orders that are in effect as of the date of publication of the order resulting from this investigation) are excluded from the scope of the investigation. Any part or subassembly that otherwise meets the requirements of this scope and that is not covered by other antidumping and/or countervailing duty orders remains subject to the scope of the investigations. The scope excludes aluminum extrusions contained in fully and permanently assembled merchandise, if the assembled merchandise is not a part or subassembly of a larger whole. To be excluded under this paragraph, the assembled merchandise must also contain a component other than aluminum extrusions, beyond fasteners. In addition, to be excluded under this paragraph, the assembled merchandise must be ready for use as imported, without undergoing after importation any processing, fabrication, finishing, or assembly or the addition of parts or material (with the exception of consumable parts or material or interchangeable media or tooling). The scope also excludes aluminum extrusions contained in unassembled merchandise if the unassembled merchandise is not a part or subassembly of a larger whole. To be excluded under this paragraph, the unassembled merchandise must also contain a component other than aluminum extrusions, beyond fasteners. In addition, to be excluded under this paragraph, the unassembled merchandise must be a packaged combination of parts that is ready to be assembled as imported, without undergoing after importation any processing, fabrication, or finishing or the addition of parts or material (with the exception of consumable parts or material or interchangeable media or tooling). To be excluded under this paragraph, the unassembled merchandise must be sold and enter as a discrete kit on one Customs entry form. Examples of such excluded assembled and unassembled merchandise include windows with glass, door units with door panel and glass, motor vehicles, trailers, furniture, appliances, and solar panels and solar modules. The scope also excludes merchandise containing multiple subassemblies of a larger whole with non-extruded aluminum components beyond fasteners. A subassembly that meets the definition of subject merchandise, including any product expressly identified as subject merchandise in this scope, can only be excluded if it is fully and permanently assembled with at least one other different subassembly, and where (1) at least one of the subassemblies, if entered individually, would not itself be subject to the scope; (2) the aluminum extrusions within the merchandise collectively account for 50 percent or less of the actual weight of the combined multiple subassemblies (without including any non-extruded aluminum fasteners in the calculations); and (3) the aluminum extrusions within the merchandise collectively account for 50 percent or less of the number of pieces of the combined multiple subassemblies (without including any non-extruded aluminum fasteners in the calculations). The scope also includes aluminum extrusions that have been further processed in a third country, including, but not limited to, the finishing and fabrication processes described above, assembly, whether with other aluminum extrusion components or with non-aluminum extrusion components, or any other processing that would not otherwise remove the merchandise from the scope if performed in the country of manufacture of the in-scope product. Third country processing; finishing; and/or fabrication, including those processes described in the scope, does not alter the country of origin of the subject aluminum extrusions. The following aluminum extrusion products are excluded: aluminum extrusions made from an aluminum alloy with an Aluminum Association series designations commencing with the number 2 (or proprietary equivalents or other certifying body equivalents) and containing in excess of 1.5 percent copper by weight; aluminum extrusions made from an aluminum alloy with an Aluminum Association series designation commencing with the number 5 (or proprietary equivalents or other certifying body equivalents) and containing in excess of 2.0 percent magnesium by weight; and aluminum extrusions made from an aluminum alloy with an Aluminum Association series designation commencing with the number 7 (or proprietary equivalents or other certifying body equivalents) and containing in excess of 2.0 percent zinc by weight.
