Chapter 76 covers aluminum and articles thereof, and is an important part of the broad category of base metals and articles thereof in the HS classification (Chapters 72-83). This chapter includes unwrought aluminum, aluminum powder, aluminum bars, rods and profiles, aluminum wire, aluminum plates, sheets and strip, aluminum foil, aluminum tubes and tube fittings, aluminum structures, aluminum containers, etc. Within the chapter, items are arranged from light to deep processing: raw materials → semi-finished products → finished products → miscellaneous articles. 7608 is located at the semi-finished tube stage, adjacent to 7609 tube fittings. Heading 7608 covers aluminum tubes and tube fittings, including seamless aluminum tubes, welded aluminum tubes, riveted aluminum tubes, and aluminum pipe fittings, elbows, flanges, and other fittings. However, according to HS notes, this heading does not include aluminum tubes made into specific articles (such as tube fittings already equipped with valves), nor does it include aluminum structures (classified under 7610). 7608 is subdivided by material into two subheadings: pure aluminum tubes and aluminum alloy tubes. Code 760820 has 6 digits: the first 2 digits 76 = Chapter 76 (aluminum and articles thereof), indicating that the commodity category belongs to aluminum materials; digits 3-4 08 = heading 7608 (aluminum tubes and tube fittings), indicating that the specific commodity type is tubular products; digits 5-6 20 = subheading 760820 (aluminum alloy tubes), indicating that the material is aluminum alloy rather than pure aluminum. If it were a pure aluminum tube, it would be classified under 760810. Digits 5-6 are the key level for distinguishing materials, because aluminum alloy and pure aluminum differ significantly in industrial use and mechanical properties, and customs statistics and trade controls need to distinguish them. This commodity is an aluminum alloy tube, made of aluminum alloy, in tubular form, not made into a specific article, and therefore classified under 760820. If it were a pure aluminum tube, it should be classified under 760810; if it were an aluminum tube fitting (such as a connector or elbow), it should be classified under 760900; if it had been processed into an aluminum structure (such as scaffolding tube), it should be classified under 761090. The core of classification lies in material (aluminum alloy) + form (tube) + degree of processing (not made into a specific article).

Product name: The standard name of the declared commodity should include material and form, such as "aluminum alloy tube". Material: Specific aluminum alloy grade or composition, such as 6061, 6063, 3003, etc., and must comply with GB/T or ASTM standards. Specification and model: Outer diameter × wall thickness × length, or marked according to use, such as "Φ50×3×6000mm". Processing method: Seamless, welded, extruded, drawn, etc., affecting classification and customs valuation. Use: Specific application scenario, such as "used for automobile radiators" or "building curtain wall support". Brand: Manufacturer or brand name; if there is no brand, indicate "no brand". Quantity and unit: Declare the first legal unit (kilogram) and the second legal unit (meter), and accurate conversion is required. Product name: aluminum alloy tube; Material: 6061 aluminum alloy; Specification: outer diameter 50mm, wall thickness 3mm, length 6000mm; Processing method: extruded seamless; Use: used for hydraulic systems of mechanical equipment; Brand: no brand; Quantity: 5000 kg/1000 m; Origin: China. Mistakenly classifying aluminum alloy tubes as pure aluminum tubes under 760810, resulting in an incorrect subheading. Ignoring the processing method and declaring welded tubes as seamless tubes, triggering customs questioning. The description of use is too general to prove that it has not been made into a specific article.

Core basis for classification: 1) the material is aluminum alloy (not pure aluminum); 2) the form is tubular (not rod, profile, or plate); 3) it has not been made into a specific article (such as not equipped with fittings or further processed into a structural component). According to HS notes, 7608 includes aluminum tubes and tube fittings, but excludes assembled finished products. Aluminum alloy tubes are usually made by extrusion or drawing; if subsequently processed into specific parts, they may be classified under other headings. 760810 Pure aluminum tubes: The material is pure aluminum (aluminum content ≥99%), whereas 760820 is aluminum alloy tubes. The difference lies in alloying element content; pure aluminum tubes have lower strength and are mostly used for electrical conduction and heat dissipation. 760900 Aluminum tube fittings: Refers to connecting parts such as pipe connectors, elbows, and flanges, rather than the tube body itself. If an aluminum alloy tube is already equipped with connectors, it may be classified under 760900 or as a finished product. 761090 Other aluminum structures: Refers to aluminum components used in structures such as buildings and bridges, such as scaffolding and door and window frames. If an aluminum alloy tube has been processed into a specific structural component, it should be classified under 761090. 760429 Other aluminum alloy bars, rods and profiles: Refers to solid bars, rods, or profiles, not hollow tubular products. If an aluminum alloy tube is flattened or processed into a profile, it should be classified under 760429. Is the material aluminum alloy? Is it hollow and tubular? Has it not been made into a specific article? Is the processing method clear? Are the specifications complete?

How do I look up the HS code for aluminum alloy tubes? First confirm that the material is aluminum alloy, the form is tubular, and it has not been made into a specific article. Then follow the HS chapter order: Chapter 76 → 7608 → 760820. You may refer to the Import and Export Tariff or customs classification decisions and search using the keyword "aluminum alloy tube". What is the difference in classification between aluminum alloy tubes and pure aluminum tubes? Pure aluminum tubes are classified under 760810, and aluminum alloy tubes under 760820. The difference lies in aluminum content: pure aluminum means aluminum content ≥99%, while aluminum alloy has added elements such as magnesium, silicon, and copper. When classifying, material certification or grade must be provided. Do welded aluminum alloy tubes and seamless aluminum alloy tubes have the same code? Yes, both are classified under 760820, because the HS does not distinguish by processing method at the subheading level. However, the processing method must be truthfully filled in at declaration, and customs may use it for valuation or statistics. If an aluminum alloy tube is cut into short sections, is it still classified under 760820? If it is only cut and not further processed, it is still classified under 760820. If after cutting it is used for specific machine parts, it may be classified as a finished product. The key is whether it has the essential character of a finished product. What are the regulatory conditions for aluminum alloy tubes classified under 760820? Generally there are no special regulatory conditions, but attention should be paid to whether anti-dumping or countervailing measures are involved. For details, consult General Administration of Customs announcements or a customs broker. When declaring aluminum alloy tubes, must the brand and model be provided? The brand must be declared; if there is no brand, indicate "no brand". The model is not mandatory, but specifications are recommended to assist classification. If the brand involves intellectual property, authorization must be provided. How are aluminum alloy tubes distinguished from aluminum tube fittings? Aluminum alloy tubes are the tube body itself and are classified under 760820; tube fittings are connecting parts such as connectors and elbows and are classified under 760900. If the tube body is already equipped with fittings, it is classified as a finished product. What is the export tax rebate rate for HS code 760820? The rebate rate may change, so the latest export tax rebate rate database must be consulted. Generally, aluminum alloy tubes have a rebate, but the specific rate is subject to publication by the tax authorities. It is recommended to use a "tax rebate rate inquiry" tool.
