Chapter 72 covers iron and steel smelting and primary iron and steel products, including pig iron, ferroalloys, direct reduced iron, scrap steel, steel ingots and various semi-finished steel products (such as slabs, billets), as well as hot-rolled or cold-rolled flat products, long products, etc. However, further processed iron and steel products (such as cold-formed sections) are classified under Chapter 73 if they exceed the scope of the chapter notes. This chapter is the basic classification for the steel trade and involves global commodity circulation. Heading 7216 covers angles, shapes and sections of iron or non-alloy steel, but does not include further processed products (such as drilled or punched). Specifically, it includes hot-rolled, hot-drawn, or extruded angle steel, channel steel, I-beams, H-beams, T-beams, etc., as well as cold-formed sections. However, cold-formed sections must be distinguished according to whether they have undergone further processing; if only cold-formed, they are classified under 7216, while if welded, riveted, etc., they are classified under 7301 or 7308, etc. The first 2 digits 72 represent Chapter 72 iron and steel, covering everything from raw materials to semi-finished products and basic sections; digits 3-4, 16, represent heading 7216, namely angles, shapes and sections of iron or non-alloy steel; digits 5-6, 61, are the subheading, specifically referring to cold-formed channel steel, i.e., channel steel produced by a cold-forming process (such as roll forming), as distinct from hot-rolled channel steel (subheading 7216.31, etc.). Cold-formed channel steel usually has thinner walls and high dimensional precision, and is widely used in construction and machinery manufacturing. This product is cold-formed channel steel, belonging to sections of iron or non-alloy steel. Because it has not undergone further processing (such as welding or drilling) and the material is ordinary steel, it is classified under 7216. If it were stainless steel cold-formed channel steel, it would be classified under 7222; if it were hot-rolled channel steel, it would be classified under 7216.31; if it were cold-formed and then welded or otherwise processed, it would be classified under 7301 or 7308.

🎯 Classification Logic
Core classification basis: 1) The material is iron or non-alloy steel; 2) The cross-sectional shape is channel-shaped; 3) The processing method is cold-forming; 4) It has not undergone further processing (such as welding, riveting, drilling, etc.). If the above conditions are met, it is classified under subheading 7216.61. If it is stainless steel, it is classified under 7222; if it is hot-rolled, it is classified under 7216.31; if it is cold-formed and then welded, etc., it is classified under 7301 or 7308. 7216.31 Hot-rolled channel steel: Hot-rolled channel steel is formed by hot rolling, has scale on the surface, and lower dimensional precision; cold-formed channel steel is formed by cold bending, has a smooth surface, and high dimensional precision. 7222.40 Stainless steel cold-formed channel steel: The material is stainless steel, classified under 7222; ordinary non-alloy steel cold-formed channel steel is classified under 7216. 7301.20 Welded angles, shapes and sections: If cold-formed channel steel has been welded (such as welding two channels into a box shape), it is classified under 7301; if only cold-formed, it is classified under 7216. 7308.90 Other iron or steel structural parts: If cold-formed channel steel has undergone further processing (such as drilling or assembly) to become a structural part, it is classified under 7308; if it is only a section, it is classified under 7216. Is the material non-alloy steel? Is the cross-section channel-shaped? Is the processing method cold-forming? Has it undergone further processing such as welding or drilling? Is it used for structural parts?

❓ FAQ
What is the difference between cold-formed channel steel and hot-rolled channel steel in HS codes? Cold-formed channel steel is classified under 7216.61, and hot-rolled channel steel under 7216.31. The main difference lies in the processing technology: cold-forming is by roll forming, while hot rolling is by high-temperature rolling. When declaring, the processing technology must be indicated to avoid confusion. How can one determine whether cold-formed channel steel has undergone further processing? Further processing includes welding, riveting, drilling, punching, bending, etc. If it is only cold-formed with no other processing, it is classified under 7216; if it has been welded, etc., it may be classified under 7301 or 7308. Under which code should stainless steel cold-formed channel steel be classified? Stainless steel cold-formed channel steel is classified under 7222.40, not 7216. This is because 7216 applies only to non-alloy steel, while stainless steel is alloy steel and must be classified under other headings of Chapter 72. When declaring cold-formed channel steel, how should the specifications and dimensions be filled in? The cross-sectional dimensions (height × leg width × web thickness) and length should be filled in, for example 100×50×3mm×6000mm. If expressed by model, the corresponding standard must be indicated. Dimensions should be uniformly in millimeters. How does the grade of cold-formed channel steel affect classification? The grade itself does not affect classification, but the material (non-alloy steel) is a prerequisite for classification under 7216. If the grade indicates alloy steel, it must be classified under other headings. When declaring, the grade should be provided to prove the material. Does the code change after cold-formed channel steel is galvanized? If after galvanizing it is still cold-formed channel steel and has not been further processed, it is usually still classified under 7216, but note that galvanizing may be regarded as surface treatment and does not affect classification. If after galvanizing it becomes another product, the code may change. How can the tariff rate for cold-formed channel steel be checked? The tariff rate must be determined according to the specific trading country and country of origin, and can be checked in the importing country's customs tariff or through official databases. Chinese exporters can refer to the Customs Import and Export Tariff of the People's Republic of China. What are the common errors when classifying cold-formed channel steel? Common errors include: mistakenly declaring cold-formed as hot-rolled, mistakenly declaring non-alloy steel as stainless steel, and failing to indicate further processing, leading to incorrect classification. It is recommended to provide detailed specifications and processing descriptions.
