Chapter 72 covers iron and steel and articles thereof, including pig iron, ferroalloys, direct reduced iron, scrap, ingots, semi-finished products, flat-rolled products, bars, wire rods, angles, sections, tubes, etc. This chapter is classified hierarchically by smelting state, composition, shape, rolling process, etc., and is the foundational classification chapter for global steel trade. Heading 7225 covers flat-rolled products of other alloy steel, of a width of 600 mm or more, whether hot-rolled or cold-rolled, but excluding further worked or specific-use steel. Under this heading, it is further subdivided by rolling method, thickness, surface treatment, etc. 722550 specifically refers to alloy steel coils, cold-rolled, not further worked, of a thickness of 0.5 mm or more but not exceeding 1 mm. First 2 digits 72 = Chapter 72 Iron and steel; digits 3-4: 25 = heading 7225, indicating flat-rolled products of other alloy steel, of a width of 600 mm or more; digits 5-6: 50 = subheading 722550, referring to alloy steel coils, cold-rolled (cold-reduced), not clad, plated or coated, of a thickness of 0.5 mm or more but not exceeding 1 mm. If the thickness is less than 0.5 mm, is it classified under 722550? In practice, 722550 covers thickness of 0.5 mm or more and up to 1 mm; thinner or thicker products must be classified under other subheadings. This product is a cold-rolled alloy steel coil, of a width of 600 mm or more, not further worked after cold rolling, with a thickness between 0.5 and 1 mm, conforming to the description of 722550. If the width is less than 600 mm, it should be classified under 7226; if hot-rolled, it should be classified under other subheadings of 7225; if already coated or plated, it should be classified under other subheadings of 7225 or 7226. Therefore, 722550 is the precise classification.

Product name: The declared product name should be specific as "cold-rolled alloy steel coil", avoiding the generic term "steel". Material: Fill in the specific grade and chemical composition of the alloy steel, such as "alloy steel, containing 1.5% chromium". Specifications: Include thickness, width, coil weight, etc., such as "thickness 0.8 mm, width 1250 mm". Degree of processing: Indicate cold-rolled, whether annealed, skin-passed, etc., such as "cold-rolled, annealed". Surface treatment: Describe whether plated, coated, oiled, etc., such as "not plated, coated with anti-rust oil". Use: Fill in the actual use, such as "used for automotive structural parts". Brand: Fill in the manufacturer or brand; if no brand, write "none". Origin: Fill in the country or region of production, such as "China". Product name: cold-rolled alloy steel coil; Material: alloy steel, containing 1.2% chromium, 0.5% molybdenum; Specifications: thickness 0.8 mm, width 1250 mm, coil weight 10 tons; Degree of processing: cold-rolled, annealed, skin-passed; Surface treatment: not plated, coated with anti-rust oil; Use: used for manufacturing automotive structural parts; Brand: Baosteel; Origin: China. Using inches for thickness units, leading to classification errors Misreporting alloy steel as non-alloy steel, affecting tax rates Confusing cold-rolled with hot-rolled, failing to provide rolling process certification Misreporting surface oiling as coating, which may lead to classification under other codes

Core basis for classification: 1. The material is alloy steel (not stainless steel), conforming to the notes to Chapter 72; 2. Flat-rolled product, of a width of 600 mm or more; 3. Cold-rolled (cold-reduced), not further worked; 4. Thickness between 0.5 mm and 1 mm; 5. Not clad, plated or coated. It is also necessary to check whether it meets the exclusion conditions of other subheadings of 7225. 722540 Other alloy steel cold-rolled sheet: 722540 is cold-rolled flat-rolled alloy steel of a thickness >1 mm, while 722550 is of a thickness ≤1 mm and ≥0.5 mm. 722550 Cold-rolled alloy steel coil: This code, thickness 0.5-1 mm, cold-rolled, uncoated. 722692 Cold-rolled alloy steel narrow strip: 722692 is of a width <600 mm, while 722550 is of a width ≥600 mm. 722530 Hot-rolled alloy steel coil: 722530 is hot-rolled, while 722550 is cold-rolled. 722599 Other alloy steel cold-rolled sheet: 722599 is cold-rolled alloy steel of a thickness <0.5 mm or >1 mm, or otherwise worked. Is the width ≥600 mm? Is it cold-rolled rather than hot-rolled? Is the thickness between 0.5-1 mm? Is it not plated or coated? Does the alloying element content meet the definition of alloy steel?

How can I check the import tax rate for 722550? You can check through the official website of the General Administration of Customs, China International Trade Single Window, or the CCPIT. Tax rates vary depending on trade agreements and country of origin. It is recommended to use official tariff query tools, entering the code and country of origin to obtain real-time tax rates. What is the difference between 722550 and 722540? The main difference is thickness: 722550 has a thickness of 0.5 mm to 1 mm, while 722540 has a thickness greater than 1 mm. When classifying, thickness must be accurately measured in millimeters to avoid confusion. What documents are required when declaring cold-rolled alloy steel coils? Typically, a contract, invoice, packing list, bill of lading, certificate of origin, quality certificate (including chemical composition and mechanical properties), and thickness and width inspection reports are required. If claiming preferential tariff rates, the corresponding certificate of origin must be provided. If the alloy steel coil has been oiled, does it affect classification? Anti-rust oiling is a surface treatment but does not change the essential characteristics, so it is still classified under 722550. If oiling is misreported as coating, it may be classified under 722599 or other codes, resulting in classification errors. Under which code should cold-rolled alloy steel coils with a width less than 600 mm be classified? They should be classified under heading 7226, with the specific subheading determined by thickness and processing state, such as 722692 (cold-rolled narrow strip). When classifying, the width must be verified to avoid confusion with 722550. Are exports of products under 722550 subject to export duties? China imposes export duties on certain steel products, but the rates and scope are subject to adjustment. It is recommended to check the latest export tariff schedule or consult the local customs. Currently, 722550 may be subject to export duties, subject to official announcements. How can alloy steel be distinguished from non-alloy steel? According to the notes to HS Chapter 72, alloy steel must contain a certain proportion of alloying elements (such as aluminum, chromium, copper, nickel, etc.) exceeding specified thresholds. Non-alloy steel does not contain them or contains them below the thresholds. When declaring, a chemical composition analysis report should be provided. When importing 722550, what does customs focus on during price verification? Customs will focus on whether the transaction price is genuine, including adjustments for freight, insurance, etc. If the declared price is significantly lower than similar products in the same period, a price challenge may be initiated. It is recommended to keep complete transaction documents and payment records.
