Chapter 72 covers iron and steel and articles thereof as basic materials, including pig iron, ferroalloys, scrap, ingots, and various semi-finished and finished steel products. This chapter is the most important chapter on metal materials in international trade, involving the complete industrial chain from raw materials to rolled products. Heading 7215 falls within the scope of "other alloy steel bars" in this chapter, distinguished from ordinary carbon steel and stainless steel, emphasizing alloying element content and cold working processes. Heading 7215 covers bars of other alloy steel, and only includes products that have been cold worked (cold formed, cold finished, cold drawn, etc.) or further worked but not coated, plated, or coated. Bars generally refer to solid cross-sections, with length greater than width, and not in coils. This heading is further subdivided into subheadings based on different alloying element content and processing states. 721550 specifically refers to alloy steel bars that have been cold worked without further surface treatment. First 2 digits 72: indicates Chapter 72 Iron and Steel, covering all iron and steel materials. Digits 3-4, 15: indicates heading 7215, i.e., bars of other alloy steel, excluding stainless steel and high-speed steel. Digits 5-6, 50: indicates subheading 721550, specifically "bars of other alloy steel, cold worked or cold finished," distinguished from products that are hot worked or forged without cold working. This subheading may be further subdivided based on alloying elements, but the core determinant is the cold worked state. The goods are cold worked alloy steel bars, conforming to the description of heading 7215, and due to the cold working process are classified under 721550 rather than hot worked subheadings 721510 or 721520. Cold working refers to plastic deformation below the recrystallization temperature, such as cold drawing and cold rolling, giving the product higher dimensional accuracy and surface finish. If the bars are hot rolled and only straightened or peeled, they should not be classified under this code.

🎯 Classification Logic
The core basis for classification is: 1) Material is alloy steel (not stainless steel, not high-speed steel); 2) Form is bar (solid, not in coils); 3) Processing technique is cold working (cold drawing, cold rolling, etc.); 4) Not coated, plated, or coated. Reference must also be made to the Import and Export Tariff and its notes to confirm whether it falls under heading 7215. 721510 Hot worked alloy steel bars: Different processing method: 721510 is hot rolled, forged, etc., while 721550 is cold worked. 721520 Forged alloy steel bars: 721520 is forged without cold working, while 721550 is cold worked product. 722850 Other alloy steel cold worked bars: 722850 is stainless steel cold worked bars, while 721550 is other alloy steel. 721310 Hot rolled alloy steel wire rods: 721310 is in coils, while 721550 is in straight bars. 721410 Forged alloy steel bars: 721410 is forged without cold working, while 721550 is cold worked. Is it alloy steel? Exclude stainless steel and high-speed steel. Is it a bar? Not in coils, not plate/sheet. Is it cold worked? Cold drawn, cold rolled, etc. Is it unplated or uncoated? Is the alloying element content provided?

❓ FAQ
How to determine whether an alloy steel bar belongs to 721550? First confirm the material is alloy steel (not stainless steel, not high-speed steel), the form is straight bar, and it has been cold worked (such as cold drawn, cold rolled), with no surface plating. If it is hot rolled or forged and only straightened, it is classified under 721510 or 721520. What is the difference between cold drawing and cold rolling? Does it affect classification? Cold drawing is pulling through a die, cold rolling is rolling through rollers. Both belong to cold working and there is no difference under 721550, but the processing method must be truthfully declared. If the alloy steel bar surface is coated with anti-rust oil, does it affect classification? Applying anti-rust oil only serves temporary protection and is not considered a coating, so it does not affect classification. However, if permanent coating such as galvanizing or painting is applied, it may be classified under other headings. Can bars under 721550 be further processed? Yes, but if processing changes the essential character (such as becoming parts), they may be classified under other chapters. If only cutting, straightening, etc., they remain under 721550. How to provide alloying element content during declaration? Specific grade and chemical composition must be provided, such as C, Cr, Mo content of 42CrMo. If the grade is unclear, a composition analysis report must be provided. What is the main difference between 721550 and 722850? 722850 is stainless steel cold worked bars, 721550 is other alloy steel cold worked bars. The key difference is whether the material is stainless steel (containing chromium ≥10.5%). If the bar is coiled cold worked alloy steel, where is it classified? Coiled cold worked alloy steel should be classified under 721710 (other alloy steel cold worked wire rods), not 721550. What are the common customs challenges for 721550 declarations? Common challenges include: whether the processing method is indeed cold working, whether alloying element content meets the standard, whether plating has been applied, etc. It is recommended to retain production process flow and material certificates.
