Chapter 72 covers iron and steel and articles thereof, including pig iron, ferroalloys, waste and scrap, primary steel products, and various rolled, drawn, and extruded semi-finished and finished steel products. This chapter is subdivided by smelting, processing form, and alloy composition. Heading 7228 falls under the category of 'Other bars and rods of other alloy steel; angles, shapes and sections, of other alloy steel; hollow drill bars and rods, of alloy or non-alloy steel' and is an important tariff heading for alloy steel long products. Heading 7228 includes: other bars and rods of other alloy steel (forged, hot-rolled, hot-drawn, etc.), angles, shapes and sections of alloy steel (whether or not further worked), and hollow drill bars and rods. Sections refer to alloy steel long products with specific cross-sectional shapes (such as H-shape, I-shape, channel, angle, etc.), distinguished from ordinary steel sections (7216) and stainless steel sections (7222). First 2 digits 72 = Iron and steel chapter; digits 3-4, 28 = Other bars and rods of other alloy steel, angles, shapes and sections, and hollow drill bars and rods; digits 5-6, 20 = angles, shapes and sections of alloy steel. Subheading 722820 specifically refers to angles, shapes and sections of alloy steel, i.e., steel other than stainless steel, containing by weight one or more alloying elements exceeding the specified limits, formed by hot working or cold working (cold drawing, cold rolling) into various cross-sectional profiles. The goods are made of alloy steel and are in the form of sections, so they are classified under 7228 rather than 7216 (ordinary steel sections) or 7222 (stainless steel sections). If they were alloy steel bars and rods (not sections), they would be classified under other subheadings of 7228; if they were hollow drill bars and rods, they would be classified under 7228.80. The cross-sectional shape and alloy composition are the key distinguishing factors.

Product name: The specific name of the declared goods, such as 'alloy steel H-beam,' 'alloy steel angle,' etc., which must be consistent with the actual goods. Material: Fill in the steel grade or chemical composition, indicating alloying elements and their content, such as 'containing 1.5% chromium, 0.5% molybdenum.' Cross-sectional shape: Describe the cross-section of the section, such as H-shape, I-shape, channel, angle, T-shape, Z-shape, etc., and a sketch may be attached. Specifications and dimensions: Fill in the cross-sectional dimensions (height, width, thickness) and length, in millimeters. Processing method: Explain the forming process, such as hot rolling, hot extrusion, cold drawing, welding, etc. Grade: Fill in the standard grade, such as Q345B, 40Cr, etc., or according to foreign standards. Use: Briefly describe the main use, such as building structures, machinery manufacturing, bridges, etc. Product name: Alloy steel H-beam; Material: containing 1.2% chromium, 0.3% molybdenum, remainder iron; Cross-sectional shape: H-shape, height 200mm, width 200mm, web thickness 8mm, flange thickness 12mm; Specifications and dimensions: 200×200×8×12mm, length 12000mm; Processing method: hot rolling; Grade: Q345B; Use: building steel structure. Failure to accurately declare the content of alloying elements, making it impossible to determine whether it is alloy steel. Unclear description of cross-sectional shape, misclassifying sections as bars and rods. Incorrect declaration of processing method, affecting classification.

Core basis for classification: 1) The material is alloy steel (not stainless steel) and must meet the definition of alloy steel in the Notes to Chapter 72; 2) The form is sections, i.e., long products with specific cross-sectional shapes, distinguished from bars and rods (same cross-section throughout the length) and plates and strips; 3) The processing method is not limited, but it must meet the definition of sections. If it is hollow drill bars and rods, it is classified under 7228.80. 7216 Ordinary steel sections: The material is non-alloy steel, whereas 7228 is alloy steel. The content of alloying elements is the key distinguishing factor. 7222 Stainless steel sections: Stainless steel contains ≥10.5% chromium and may contain other elements, whereas 7228 is other alloy steel. 7228.30 Alloy steel bars and rods (hot-rolled): Bars and rods are solid long products with the same cross-section throughout the length, while sections have cross-sectional shapes that are not simple circles or rectangles. 7228.80 Hollow drill bars and rods: Hollow drill bars and rods are hollow rods used for drilling, while sections have solid cross-sections. Is the material alloy steel? Is the cross-section not a simple circle or rectangle? Is the cross-sectional shape consistent throughout the length? Has it undergone further processing? Does it belong to hollow drill bars and rods?

How do I determine whether my alloy steel sections should be classified under 7228 or 7216? The key is the material: if the steel contains one or more alloying elements (such as chromium, nickel, molybdenum, vanadium, etc.) exceeding the limits specified in the Notes to Chapter 72, it is alloy steel and should be classified under 7228; otherwise, it is ordinary steel and is classified under 7216. It is recommended to provide a chemical composition report. What is the difference in classification between alloy steel sections and alloy steel bars and rods? Sections have non-simple cross-sectional shapes (such as H-shape, channel, etc.), while bars and rods usually have simple solid cross-sections such as circular, square, or rectangular. If the cross-section is a simple shape, even alloy steel should be classified as bars and rods (such as 7228.30). How should the 'Cross-sectional shape' field be filled in during declaration? The cross-sectional geometry should be described in detail, such as 'H-shape, height 200mm, width 200mm, web thickness 8mm, flange thickness 12mm,' with a sketch attached. Avoid writing only 'sections' or 'special-shaped sections.' Does the processing method of alloy steel sections affect classification? Yes, it does. Different processing methods such as hot rolling, hot extrusion, and cold drawing may affect subheading determination, but 7228.20 covers alloy steel sections of various processing methods. The processing method must be accurately declared. How are hollow drill bars and rods distinguished from alloy steel sections? Hollow drill bars and rods are hollow rods used for drilling, usually with an inner bore, while sections have solid cross-sections. If they are hollow drill bars and rods, they should be classified under 7228.80, not 7228.20. What documents are required for importing alloy steel sections? Usually, material certification (chemical composition), specifications and dimensions, cross-sectional shape drawings, processing method, grade, and use are required. If necessary, a certificate of origin, quality inspection report, etc., should be provided. Are there further subdivided codes under subheading 7228.20? The first 6 digits of the HS code are internationally standardized. Under 7228.20, individual countries may subdivide digits 7-10 according to their national circumstances. China Customs has specific subheadings, which require consulting the 'Import and Export Tariff of the People's Republic of China.' If alloy steel sections undergo further processing (such as drilling or bending), will the classification change? If only minor processing is performed and the basic characteristics of sections are retained, they are generally still classified under 7228.20; if processed into specific articles (such as steel structural components), they may be classified under Chapter 73. The determination should be based on the degree of processing.
