Chapter 76 covers all aluminum and articles thereof, from raw materials (such as aluminum ingots and aluminum materials) to various finished products (such as aluminum containers, aluminum tableware, aluminum structures, etc.). This chapter does not include aluminum compounds (classified under Chapter 28), aluminum machine parts (classified under Chapters 84/85), or aluminum furniture (classified under Chapter 94). The core is articles made primarily of aluminum that are not specifically named in other chapters. Heading 7610 specifically refers to aluminum structures and parts thereof, such as aluminum frames for construction, doors and windows, curtain walls, bridges, towers, roofs, railings, etc., as well as aluminum plates, profiles, tubes, and other parts dedicated to these structures. However, note that these parts must be processed (such as drilled, bent, assembled) and dedicated to structures; basic aluminum materials without further processing (such as bare profiles) should be classified under 7601-7609. First 2 digits 76: represents Chapter 76, i.e., aluminum and articles thereof. Digits 3-4, 10: represents heading 7610, i.e., aluminum structures and parts thereof. Digits 5-6, 00: since there are no further subheadings under this heading, the fifth and sixth digits are 00, indicating that all goods under this heading are uniformly classified under this code. The overall code 761090 refers to aluminum structures and parts thereof, with no finer classification. This product is classified under 7610 rather than 7601-7609 because it already constitutes a structure or a part dedicated to a structure, going beyond the scope of basic aluminum materials. At the same time, it is not classified under Chapter 94 as furniture, because structures are usually fixedly installed in buildings or civil engineering works and do not have the mobility and independent use functions of furniture. Therefore, 7610 is the most appropriate classification.

Product Name: The specific name of the declared commodity, such as aluminum curtain wall, aluminum door and window frame, etc., which should accurately reflect the purpose and material of the commodity. Material: State the aluminum grade or alloy composition, such as 6063 aluminum alloy, pure aluminum, etc., and whether other materials are included (such as glass, sealing strips). Purpose: Clearly specify the use scenario of the commodity, such as building curtain walls, bridge structures, roof frames, etc., and it must be specific to the type of project. Specifications and Dimensions: Provide main dimensions, such as length, width, thickness, cross-sectional shape, etc.; for profiles, cross-sectional dimensions should be indicated. Processing Method: State whether drilling, bending, welding, assembly, or other processing has been performed, and the degree of processing. Brand: If there is a brand, the brand name must be declared; if there is no brand, declare as "no brand." Model: Declare the model or series number of the product to facilitate identification of the specific commodity. Whether in Sets: If it is a complete set of structural components, state whether it is imported as a set and provide a list of components. Product Name: Aluminum alloy curtain wall frame; Material: 6063-T5 aluminum alloy; Purpose: Used for supporting exterior building curtain walls; Specifications: Length 6000mm, cross-sectional dimensions 100mm×50mm; Processing Method: Cut, drilled, assembled; Brand: XX; Model: MQ-100; Whether in Sets: Yes, including columns, beams, and connectors. Incorrectly classifying unprocessed aluminum profiles (such as those merely extruded) under 7610, when they should actually be classified under 7604. Ignoring the processing method; if only simply cut but not constituting a structural part, it may still be classified under 7604. Purpose description not specific, such as only writing "for construction," without clarifying whether it is a structure or a decorative piece, which easily leads to classification disputes.

The core criterion for classification is whether the commodity already constitutes a "structure" or a "part dedicated to a structure." A structure usually refers to load-bearing or enclosure components used in buildings, bridges, towers, and other engineering works, and has been processed (such as drilled, bent, assembled) to be dedicated to that structure. If it is only basic aluminum material (such as profiles, tubes) without further processing, it is classified under 7601-7609. In addition, if the structure is combined with machinery or equipment, it may be classified under Chapters 84/85. 7604 Aluminum bars, rods, profiles, and shaped sections: 7604 is basic aluminum material without further processing, such as extruded profiles; while 7610 is processed into structures or parts dedicated to structures, such as frames after drilling and bending. 7611 Aluminum tanks, vats, drums, and similar containers: 7611 is containers for holding materials, while 7610 is structures used for building or engineering support; their functions are different. 7612 Aluminum drums, cans, boxes, and similar containers: 7612 is small containers, such as beverage cans, while 7610 is large structures; their uses and dimensions are significantly different. 7615 Aluminum tableware, kitchenware, etc.: 7615 is household utensils, while 7610 is industrial or construction structures; their uses are completely different. 9406 Prefabricated buildings: 9406 is movable prefabricated buildings, while 7610 is fixedly installed structural parts; whether it is movable is the key difference. Does the commodity already constitute a structure or a part dedicated to a structure? Has it undergone further processing such as drilling, bending, or assembly? Is it used for fixed engineering works such as buildings or bridges? Is it combined with machinery or equipment? Is it movable or capable of independent use?

Should aluminum door and window frames be classified under 7610 or 7604? If the door and window frames have been processed and formed, are dedicated to building doors and windows, and have undergone cutting, drilling, assembly, etc., they should be classified under 7610. If they are only unprocessed aluminum profiles, they are classified under 7604. The key is whether they have become parts dedicated to structures. How should aluminum curtain wall components be declared? Curtain wall components usually consist of aluminum profiles, glass, sealing parts, etc. If the aluminum part already constitutes a structural component, it should be classified under 7610. When declaring, the material, purpose, and processing method must be indicated, and whether it is in sets must be stated. What is the difference between 7610 and 7611? 7611 is aluminum containers used for holding materials, such as tanks, vats, and drums; 7610 is structures used for building or engineering support. Their functions are different, and classification should be determined based on purpose. Which code should aluminum bridge components be classified under? If aluminum bridge components have been processed into structural parts dedicated to bridges, they should be classified under 7610. If they are basic aluminum materials, they are classified under 7604. Processing proof and purpose description must be provided. How can I check the import tariff rate for goods under 7610? The import tariff rate must be determined based on the country of origin, trade agreements, etc. You may consult the "Import and Export Tariff" published by the General Administration of Customs or use a customs classification advance ruling. It is recommended to consult a professional customs broker or customs authority. How are aluminum structural parts distinguished from machine parts? If structural parts are combined with machinery and become an inseparable part of the machine, they should be classified under Chapters 84/85. If they are used independently as structures, they are classified under 7610. The key is whether they have an independent function. What are common errors when declaring 7610? Common errors include: incorrectly classifying unprocessed aluminum materials under 7610, vague purpose descriptions, failure to state the processing method, failure to provide specifications and dimensions, etc. Detailed declaration is recommended to avoid classification disputes. Are goods under 7610 subject to anti-dumping duties? Some aluminum structures may be subject to anti-dumping measures; specifics should be checked in announcements from the General Administration of Customs. It is recommended to verify before import whether the country of origin and the commodity are on the anti-dumping list to avoid risks.
