Chapter 72 covers iron and steel and articles thereof, including pig iron, ferroalloys, direct reduced iron, ferrous waste and scrap, ingots and other primary forms, semi-finished products (such as billets and slabs), flat-rolled products, bars, wire rods, angles, shapes, profiles, tubes, etc. This chapter is the most important chapter on metal materials in international trade, involving the complete steel industry chain from raw materials to finished products. The classification of commodity codes is based on composition, shape, processing state, and use. Heading 7213 covers hot-rolled bars and rods of iron or non-alloy steel, in irregularly wound coils. It specifically includes bars and rods that are hot-rolled, hot-drawn, or hot-extruded and then coiled, as well as bars and rods that have undergone further processing after rolling (such as straightening or cutting) but still retain the characteristics of coils. Products under this heading are typically used in construction, machinery manufacturing, fastener production, etc., and are basic materials for infrastructure and manufacturing. Code 721310 has 6 digits: the first 2 digits '72' represent Chapter 72 (Iron and Steel); digits 3-4 '13' represent heading 7213 (hot-rolled bars and rods in coils); digits 5-6 '10' represent subheading 721310, specifically referring to hot-rolled, hot-drawn, or hot-extruded coiled bars and rods with indentations, ribs, grooves, or other deformations produced during the rolling process (i.e., rebar). This subheading is specifically for construction rebar, distinguished from other ordinary coiled bars and rods (such as 721320, 721391, etc.). This commodity is hot-rolled rebar, in coiled form, made of non-alloy steel, meeting the description of heading 7213. Subheading 721310 explicitly includes coiled bars and rods with deformations (such as threads or indentations), so it is classified under this code. If it were straight or cut-to-length rebar, it would be classified under 7214; if it were alloy steel rebar, it would be classified under 7228; if it were cold-worked, it would be classified under 7215 or other codes.

Incorrectly declaring coiled rebar as straight, which should be classified under 7214 rather than 7213. Ignoring alloy element content in the material; if it exceeds the limit, it may be classified under 7228. Failure to indicate 'coiled' status, leading to customs questioning the classification.
Product Name
The specific name of the declared commodity, such as 'hot-rolled rebar', and the coiled state should be indicated.
⚠️ Writing only 'rebar' without indicating hot-rolled and coiled, leading to classification errors.
Material
Explain the chemical composition of the steel, such as non-alloy steel, and indicate the content of main elements.
⚠️ Failure to provide carbon, manganese, and other contents, making it impossible to determine whether it is non-alloy steel.
Shape
Describe it as coiled, and indicate surface deformation features such as threads or indentations.
⚠️ Incorrectly declaring it as straight or cut-to-length, affecting classification.
Processing Method
Indicate processes such as hot rolling, hot drawing, or hot extrusion.
⚠️ Confusing hot rolling with cold rolling, leading to subheading errors.
Specifications and Dimensions
Declare diameter and length (coils are usually measured by weight), such as diameter 12mm.
⚠️ Failure to provide diameter, making it impossible to determine whether it is rebar.
Grade
Such as HRB400, HRB500, etc., indicating strength grade.
⚠️ Incorrect grade entry or inconsistency with material.
Use
Such as for construction, for reinforced concrete, etc.
⚠️ Use description too broad and lacking specificity.
Incorrectly declaring coiled rebar as straight, which should be classified under 7214 rather than 7213.

🎯 Classification Logic
Core basis for classification: 1) Material is non-alloy steel; 2) Processing method is hot rolling; 3) Shape is coiled; 4) Surface has deformations such as threads. Only when all the above conditions are met is it classified under 721310. If it is alloy steel, cold-worked, straight, or non-deformed, it is classified under other codes. 721320 Hot-rolled coiled bars and rods of free-cutting steel: 721320 is free-cutting steel, usually containing sulfur, lead, and other elements, while 721310 is non-alloy steel with deformations. 721391 Other hot-rolled coiled bars and rods, circular cross-section, diameter <14mm: 721391 has a circular cross-section without deformation, while 721310 has deformations (threads, etc.). 721410 Hot-rolled straight rebar: 721410 is straight or cut-to-length, not coiled; 721310 is coiled. 722820 Hot-rolled coiled bars and rods of alloy steel: 722820 is alloy steel, while 721310 is non-alloy steel. Is the material non-alloy steel? Is it hot-rolled? Is it coiled? Does the surface have deformations such as threads? Is it used for construction or similar purposes?

❓ FAQ
How can I check the import tariff rate for 721310? You can check the latest tariff rates through the official website of the General Administration of Customs of China or the International Trade Single Window, or use HS code query tools. Note that tariff rates vary by country and trade agreement. What is the difference in HS codes between coiled rebar and straight rebar? Coiled rebar is classified under 721310, while straight or cut-to-length rebar is classified under 721410. The main difference lies in the shape and state; coils are suitable for further processing, while straight bars are used directly. If the rebar is alloy steel, which code should it be classified under? Alloy steel rebar should be classified under the 7228 series. The specific subheading is determined by alloy composition and processing state, such as 722820 for hot-rolled coiled bars and rods of alloy steel. How should the 'deformation' feature be described during declaration? The type of deformation should be specified, such as threads, indentations, ribs, etc., and whether it complies with standards (such as GB/T 1499.2) should be indicated. Does 721310 include cold-rolled rebar? No. 721310 is limited to hot-rolled; cold-rolled rebar should be classified under 7215 or other corresponding codes. What should be noted when exporting rebar to the EU? Attention should be paid to EU steel quotas, anti-dumping duties, and CE certification requirements, while also confirming the corresponding tariff number of the HS code in the EU. How to distinguish between 721310 and 721391? 721310 requires surface deformations (such as threads), while 721391 has a circular cross-section without deformation and a diameter of less than 14mm. Is the 'grade' in the declaration elements mandatory? Yes, the grade helps customs confirm the commodity attributes. For example, HRB400 indicates a yield strength of 400MPa, which is an important reference for classification.
