Chapter 72 covers iron and steel smelting and primary iron and steel products, including pig iron, ferroalloys, scrap, ingots, semi-finished products (such as billets and slabs), flat-rolled products, bars and rods, angles, shapes and sections. This chapter does not include finished iron or steel products (such as pipe fittings and structural components of Chapter 73) or further worked products (such as tools of Chapter 82). The core is that the chemical composition, processing state (hot-rolled, cold-rolled, coated) and cross-sectional shape of iron and steel materials determine classification. Heading 7216 covers angles, shapes and sections of iron or non-alloy steel, but excludes further worked products (such as drilled or coated) or specific cross-sections (such as hollow drill steel). It includes sections that are hot-rolled, hot-drawn, extruded or forged and not further worked, as well as sections that are only lightly straightened, pickled or descaled. Common varieties include H-beams, I-beams, channel steel, angle steel, T-beams, Z-beams, etc. Code 721622 has 6 digits: the first 2 digits '72' represent Chapter 72 iron and steel; digits 3-4 '16' represent heading 7216, namely angles, shapes and sections of iron or non-alloy steel; digits 5-6 '22' are the subheading, specifically referring to H-beams that are hot-rolled, hot-drawn or extruded and not further worked, with a cross-sectional height of less than 80 mm. Among these, '2' indicates hot-rolling and other processing methods, and '2' further limits it to H-beams. Note: H-beams with a cross-sectional height of ≥80 mm are classified under 721633, while alloy steel H-beams are classified under 7228. The product is a hot-rolled H-beam, made of non-alloy steel, processed by hot rolling and not further worked, with a cross-sectional height of less than 80 mm, meeting all conditions of subheading 721622. If the cross-sectional height is ≥80 mm, it is classified under 721633; if it is stainless steel or alloy steel, it is classified under 7222 or 7228; if it has been cold-worked or coated, it is classified under other subheadings of 7216 or 7311, etc.

Product name: hot-rolled H-beam; Material: non-alloy steel, grade Q235B; Processing method: hot-rolled, not further worked; Cross-sectional shape: H-shaped; Cross-sectional height: 60 mm; Specifications: 60 mm × 30 mm × 4 mm × 6 mm × 6 m; Use: building structures. Failure to indicate cross-sectional height, making it impossible to distinguish 721622 from 721633. Mistakenly reporting alloy steel as non-alloy steel, which should be classified under 7228. Incomplete description of processing method, such as failure to state whether pickled or coated.

Core basis for classification: 1) The material is non-alloy steel; 2) The processing method is hot-rolled, hot-drawn or extruded, and not further worked; 3) The cross-sectional shape is H-shaped; 4) The cross-sectional height is less than 80 mm. At the same time, alloy steel, stainless steel and further worked sections (such as cold-rolled, coated or drilled) must be excluded. If the cross-sectional height is ≥80 mm, it is classified under 721633; if it is alloy steel, it is classified under 7228; if it is stainless steel, it is classified under 7222. 721633 Hot-rolled H-beams (cross-sectional height ≥80 mm): Different cross-sectional height: 721622 is for height <80 mm, 721633 is for height ≥80 mm. 722870 Alloy steel H-beams: Different material: 721622 is non-alloy steel, 722870 is alloy steel. 721610 Hot-rolled U-beams, I-beams or H-beams (height <80 mm): 721610 covers U-beams, I-beams and H-beams, but 721622 specifically refers to H-beams; attention must be paid to subheading subdivision. 721699 Other non-alloy steel sections: 721699 covers other sections not elsewhere specified, such as T-beams and Z-beams, and does not include H-beams. Is the material non-alloy steel? Is the processing method hot-rolled and not further worked? Is the cross-sectional shape H-shaped? Is the cross-sectional height less than 80 mm? Are alloy steel, stainless steel and coatings, etc., excluded?

How do I look up the HS code for hot-rolled H-beams? First confirm that the material is non-alloy steel, the processing method is hot-rolled and not further worked, and the cross-section is H-shaped. Then measure the cross-sectional height: if <80 mm, classify under 721622; if ≥80 mm, classify under 721633. If it is alloy steel, classify under 7228. It is recommended to use the Customs Tariff of the General Administration of Customs or an HS code query tool, enter the keyword 'H-beam' and filter. What is the difference in HS codes between hot-rolled H-beams and I-beams? Hot-rolled H-beams have an H-shaped cross-section, while I-beams have an I-shaped cross-section. In the HS code, H-beams have dedicated subheadings (such as 721622 and 721633), while I-beams are usually classified under 721610 (height <80 mm) or 721631 (height ≥80 mm). When declaring, accurately describe the cross-sectional shape to avoid confusion. Which code should an H-beam with a cross-sectional height of exactly 80 mm be classified under? According to HS rules, an H-beam with a cross-sectional height equal to 80 mm should be classified under 721633 (height ≥80 mm), not 721622. This is because subheading 721622 explicitly states 'height less than 80 mm', and 80 mm does not satisfy 'less than'. It is recommended to provide an accurate measurement when declaring. If hot-rolled H-beams are pickled, are they still classified under 721622? Pickling is a surface treatment. If it does not change the cross-sectional shape and material, it is usually still classified under 721622. However, if after pickling they are further coated (such as galvanized), they may be classified under other subheadings of 7216 or 7311. The processing technique must be stated when declaring. What is the HS code for alloy steel H-beams? Alloy steel H-beams are classified under heading 7228, and the specific subheading depends on the processing method and cross-sectional height. For example, hot-rolled alloy steel H-beams (height <80 mm) are classified under 722870. When declaring, the alloy element content must be provided to prove the alloy steel attribute. How should the declaration element 'cross-sectional height' be filled in during customs declaration? Fill in the actual measured value in millimeters (mm), such as '60 mm'. Avoid filling in ranges or approximate values. If it is a special-shaped section, provide a cross-sectional diagram. This element directly affects subheading classification, so it must be accurate. How do I check the tax rate for hot-rolled H-beams? Tax rates are adjusted according to national policies. It is recommended to use the official website of the General Administration of Customs, the electronic port, or a professional tariff query tool, enter HS code 721622 to obtain the latest import tariff, value-added tax and regulatory conditions. Different countries of origin may apply agreement rates. What should be noted when selling hot-rolled H-beams via cross-border e-commerce? It is necessary to confirm whether the product meets the standards of the exporting country and accurately declare the HS code to avoid customs clearance delays. Pay attention to regulatory conditions (such as export licenses and commodity inspection). If it is small-batch retail, it may involve customs clearance as personal items or low-value goods, but the HS code still needs to be correct.
