Chapter 72 covers basic materials of iron and steel and articles thereof, including pig iron, ferroalloys, scrap, ingots, semi-finished products, and flat-rolled products, bars, angles, shapes, and sections. This chapter is the core chapter for steel trade, covering a wide range of products from raw materials to primary steel products, but excluding further processed articles (such as Chapter 73). Heading 7216 specifically refers to angles, shapes, and sections of iron or non-alloy steel, including hot-rolled, hot-drawn, extruded, or further processed products. However, it excludes cold-rolled, cold-drawn, or cold-formed products (classified under 7217) and stainless steel sections (7222). Channels are a type of section with a channel-shaped cross-section, and are therefore classified under this heading. First 2 digits 72: represents Chapter 72 'Iron and Steel', covering iron and steel smelting and primary rolled products. Digits 3-4, 16: represents heading 7216 'Angles, shapes and sections of iron or non-alloy steel', distinguished from bars of 7215 and wire of 7217. Digits 5-6, 10: represents subheading 721610, specifically 'Channels, hot-rolled, hot-drawn or extruded', with cross-sectional height < 80mm. This subheading only covers channels of non-alloy steel that have not been further processed (such as coated or plated). This commodity is a hot-rolled channel, made of non-alloy steel, with a channel-shaped cross-section, meeting the definition of sections under heading 7216. It has not undergone cold working or further surface treatment, so it is not classified under 7217. The cross-sectional height is < 80mm, so it is classified under 721610 rather than 721620 (height ≥ 80mm).

Material: Indicate the steel type and chemical composition, such as 'non-alloy steel, carbon content 0.2%', and provide the specific grade such as Q235B. Processing Method: Clearly state hot-rolled, hot-drawn, or extruded; the word 'hot' cannot be omitted, as cold working is classified under different tariff codes. Cross-sectional Shape: Describe as channel-shaped and indicate the cross-sectional height (e.g., 50mm); the height determines the subheading. Cross-sectional Dimensions: Include complete dimensions such as height, leg width, and web thickness in millimeters, used to confirm the subheading. Steel Grade: Fill in the specific steel grade, such as Q235B, SS400, to facilitate customs verification of the material.

🎯 Classification Logic
Core basis for classification: 1) Material is non-alloy steel; 2) Processing method is hot-rolled; 3) Cross-section is channel-shaped, belonging to sections; 4) Cross-sectional height < 80mm. All the above conditions must be met simultaneously to be classified under 721610. If alloy steel, classified under 7228; if stainless steel, under 7222; if cold-worked, under 7217; if further processed (such as coated), under subsequent subheadings of 7216 or Chapter 73. 721620 Hot-rolled channels (cross-sectional height ≥ 80mm): Cross-sectional height ≥ 80mm, other conditions the same, different subheading. 721650 Other hot-rolled sections: Cross-section not channel-shaped, such as T-shaped, Z-shaped, etc., classified under other subheadings. 721699 Other non-alloy steel sections: Covers sections not elsewhere specified, such as those further processed but not changing classification. 722870 Alloy steel channels: Material is alloy steel, different heading. Is the material non-alloy steel? Is the processing method hot-rolled? Is the cross-section channel-shaped? Is the cross-sectional height < 80mm? Has it not undergone cold working or surface treatment?

❓ FAQ
How to look up the HS code for hot-rolled channels? First confirm the material is non-alloy steel, the processing method is hot-rolled, the cross-section is channel-shaped, then measure the cross-sectional height. If height < 80mm, classify under 721610; if ≥ 80mm, under 721620. Refer to the 'Import and Export Tariff' or use the customs classification inquiry system. What is the difference in HS codes between hot-rolled channels and cold-formed channels? Hot-rolled channels are classified under 7216, cold-formed channels under 7217 or 7308. Hot-rolling is rolling at high temperature, cold-forming is bending at room temperature; different processing methods lead to different classifications. Always indicate the processing method when declaring. How is cross-sectional height measured? Cross-sectional height refers to the vertical height of the channel web, i.e., the distance from outer edge to outer edge. Use calipers for measurement, accurate to millimeters. Height is the key to distinguishing 721610 from 721620. If the channel is galvanized, will the HS code change? Yes. If hot-rolled channels undergo surface treatment such as galvanizing, they are still classified under 7216, but the subheading may change, such as 7216.50 or 7216.99. If the coating changes the essential character, it may be classified under Chapter 73. It is recommended to indicate surface treatment when declaring. What are the consequences of omitting cross-sectional height when declaring? It may prevent customs from determining the subheading, delay customs clearance, or even result in penalties for inaccurate declaration. Complete dimensions must be provided, including height, leg width, and web thickness. How to distinguish non-alloy steel from alloy steel? According to the HS definition, non-alloy steel refers to steel with a carbon content ≤ 2.11% by weight and not containing other alloying elements exceeding specified limits. Alloy steel contains one or more alloying elements exceeding the limits. Chemical composition should be provided when declaring. How to check the tax rate for hot-rolled channels? Tax rates may change; consult the latest 'Import and Export Tariff' or Customs Administration announcements. Obtain via the customs classification inquiry system, e-port, or by consulting a customs broker. Note preferential rates under different trade agreements. What documents are required for importing hot-rolled channels? Usually require contract, invoice, packing list, bill of lading, certificate of origin, material certificate, etc. If anti-dumping is involved, relevant certificates are also required. It is recommended to consult customs or a customs broker in advance.
