1. HS Code Basic Positioning
Aluminum Rod, as the core form of aluminum processed materials, is classified in Chapter 76 (Aluminum and its products) in the Harmonized Commodity Name and Coding System (HS Code). The specific code needs to be subdivided according to the material, processing status and use:
Unwrought aluminum rod (non-alloy/alloy)
7604.10: Non-alloy aluminum rod (containing aluminum ≥ 99%), with a round, square or rectangular cross-section and a maximum cross-sectional size of > 7mm;
7604.21: Aluminum alloy hollow rod (containing aluminum < 99%), with a wall thickness of ≤ 3mm;
7604.29: Other aluminum alloy rods (solid or hollow, including special-shaped materials).
Forged aluminum bars (deep-processed finished products) 7608.20: Aluminum bars that have been drawn, rolled or extruded (diameter ≤7mm, used for wire or welding wire); 7616.99: Surface-treated aluminum bars (such as finished products after anodizing, spraying, etc.).
2. HS code extension rules of various countries Although the first 6 digits of HS are unified globally, there may be differences in the 7th to 10th digits of the codes of various countries:
China (Customs Tariff): 7604.10.9000: Non-alloy solid aluminum bars (non-circular cross-section, used for building structures); 7604.21.0000: Aluminum alloy hollow bars (wall thickness ≤3mm). United States (HTSUS): 7604.29.5090: Aluminum alloy special-shaped bars (length >6m, used for automotive parts); 7608.20.0030: Drawn aluminum wire bars (diameter ≤7mm).
EU (TARIC):
7604 21 00: Aluminum alloy hollow rod (for aerospace frames).
3. Key declaration elements and compliance requirements Composition and specifications
Clearly mark the aluminum content (e.g. 6061-T6 is Al-Mg-Si-Cu alloy), cross-sectional shape (round/rectangular/special shape);
Provide dimensional parameters (diameter/wall thickness/length) and processing status (forged/unforged).
Statement of use
Distinguish between industrial use (e.g. mechanical parts, conductive materials) or civil use (e.g. furniture accessories). Some countries may require additional use description documents.
Testing and certification
Material certification in accordance with ASTM B221 (American standard) or EN 754 (European standard);
FDA or RoHS certification is required when it involves food contact or medical fields.
Accurate classification of aluminum bar HS codes is the core link of international trade compliance. Enterprises need to adjust their declaration strategies based on material characteristics, processing depth and target market policies. It is recommended to work with a professional customs clearance agent or customs lawyer to regularly update the trade compliance database to cope with the complex changes in the global supply chain.
