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), and primary forms of bars, rods, profiles, plates, strips, and wire obtained by hot rolling, forging, or extrusion. This chapter does not include finished iron and steel products (such as pipe fittings and fasteners) or products that have undergone further cold working or coating (classified under Chapter 73 or subsequent headings of Chapter 72). The core is the basic material forms of iron and steel. Heading 7214 covers iron or non-alloy steel bars and rods that have been hot-rolled, hot-drawn, or hot-extruded and only further descaled or rough-processed, as well as bars twisted after hot rolling. It includes straight or coiled products obtained directly after forging, rolling, or extrusion, but excludes products that are cold-worked, cold-finished, coated, or further processed (classified under 7215, etc.). The first 2 digits 72 indicate Chapter 72 'Iron and steel', covering the entire chain from ore smelting to primary steel products. Digits 3-4, 14, indicate heading 7214, specifically 'Other bars and rods of iron or non-alloy steel, not further worked than forged, hot-rolled, hot-drawn or hot-extruded, but including those twisted after rolling'. Digits 5-6, 20, indicate subheading 721420, which under 7214 is further limited to 'Bars and rods, not further worked than forged, hot-rolled, hot-drawn or hot-extruded, but including those twisted after rolling, containing by weight less than 0.25% of carbon'. Note: subheading division is based on carbon content, processing state, and cross-sectional shape. The commodity is hot-rolled carbon steel bars, processed by hot rolling, made of non-alloy steel, and not cold-worked or coated, which conforms to the description of heading 7214. If the carbon content is >= 0.25%, it would be classified under 721410 or 721430, etc.; if cold-worked, under 7215; if alloy steel, under 7228. Therefore, based on processing state and material, classification under 721420 is the most accurate.

Product name: The Chinese and English names of the declared commodity should accurately reflect the material and processing state, such as 'hot-rolled carbon steel bars'. Material: Indicate non-alloy steel and declare the specific grade (such as Q235B) and chemical composition, especially carbon content. Processing state: Describe as hot-rolled, hot-drawn, or hot-extruded, and whether only descaled or rough-processed. Cross-sectional shape and dimensions: Declare cross-sectional shape such as round, square, rectangular, and dimensions such as diameter or side length, thickness. Carbon content: Express carbon content as a percentage, accurate to two decimal places, used to determine the subheading. Length: Declare fixed length or random length, and whether in coils. Use: Briefly explain the main use, such as construction, machining, etc. Product name: hot-rolled carbon steel bars; Material: non-alloy steel, grade Q235B, carbon content 0.18%; Processing state: hot-rolled, only descaled; Cross-sectional shape: round; Diameter: 20mm; Length: 6m; Use: for building structures. Mistakenly classifying hot-rolled bars that have been cold-drawn under 721420, when they should actually be classified under 7215. Failure to declare carbon content, making it impossible to distinguish 721420 from 721410 (carbon >= 0.25%). Mistakenly classifying alloy steel bars under 721420; alloy steel should be classified under 7228. Incorrect declaration of cross-sectional shape, such as reporting square steel as round steel, affecting classification.

The core basis for classification is: 1) material is non-alloy steel; 2) processing method is hot rolling, hot drawing, or hot extrusion; 3) only descaled or rough-processed, without cold working, coating, etc.; 4) carbon content less than 0.25%; 5) cross-section is solid bars such as round or square. Reference should also be made to the Import and Export Tariff and national subheading notes. 721410 Forged non-alloy steel bars: The processing method is forging, not hot rolling. If forged and then hot-rolled, it may still be classified under 7214, but judgment should be based on the primary processing method. 721430 Hot-rolled non-alloy steel bars, carbon content >= 0.25%: Different carbon content; 721430 requires carbon content >= 0.25%, while 721420 requires < 0.25%. 721510 Cold-worked non-alloy steel bars: The processing method is cold drawing, cold rolling, or other cold working, while 721420 is hot-rolled. 722820 Alloy steel bars: The material is alloy steel, while 721420 is non-alloy steel. 721310 Hot-rolled coiled bars: 721310 is in coils, while 721420 is usually straight bars, but can coiled hot-rolled bars with carbon content < 0.25% also be classified under 721420? Note: 7213 is coils, 7214 is straight bars, and distinction should be based on shape. Is the material non-alloy steel? Is the processing method hot rolling? Is the carbon content less than 0.25%? Has it not been cold-worked or coated? Is the cross-section a solid bar?

How can I check the import tariff rate for 721420? You can check the MFN rate, general rate, etc. through the official website of the General Administration of Customs of China or the Import and Export Tariff of the People's Republic of China. You can also use the customs commodity code query system and enter 721420 to obtain the latest tariff rate. Note that rates may vary due to trade agreements. What is the difference between 721420 and 721410? The main difference lies in the processing method: 721410 is forged non-alloy steel bars, and 721420 is hot-rolled non-alloy steel bars. If forged and then hot-rolled, classification is usually based on hot rolling. In the declaration elements for hot-rolled carbon steel bars, is carbon content mandatory? Yes, carbon content is key to distinguishing 721420 from 721430 and must be provided as a specific value. If it cannot be provided, it may lead to classification disputes or delays in customs clearance. If hot-rolled bars have been cold-drawn, which code should they be classified under? After cold drawing or other cold working, they should be classified under 7215 (cold-worked non-alloy steel bars), not 721420. Cold drawing changes the processing state, and classification changes accordingly. Does 721420 include hot-rolled bars in coils? No. Hot-rolled bars in coils are usually classified under 7213, while 7214 is for straight bars. However, if coiled bars meet the description of 7214, judgment should be based on cross-sectional dimensions and use. How can I determine whether bars are alloy steel? According to the HS definition, alloy steel must contain a certain proportion of alloying elements (such as manganese, silicon, chromium, etc.) exceeding specified thresholds. If it is only carbon steel, it is considered non-alloy steel. Chemical composition analysis can be referenced. What is the export tax rebate for 721420? The export tax rebate rate changes with policy adjustments. You can check the export tax rebate rate library published by the State Taxation Administration. Generally, the rebate rate for primary steel products is relatively low, and the latest documents should prevail. When declaring, how do cross-sectional shape and dimensions affect classification? Cross-sectional shape and dimensions affect subheading division; for example, round, square, etc. may correspond to different subheadings. However, 721420 does not further subdivide by shape and only requires bars. Nevertheless, dimensions may affect other headings, such as wire rods.
