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, angles, sections, wire, etc. This chapter mainly addresses ferrous materials but includes certain alloy steels and stainless steel. Note: If iron and steel products are further processed into specific articles (such as screws or tools), they are classified under Chapter 73 or subsequent chapters. This chapter is a key chapter of concern for anti-dumping and tariff-rate quotas in international trade. Heading 7225 covers flat-rolled products of other alloy steel, of a width of 600 mm or more, hot-rolled or cold-rolled (cold-reduced), whether or not in coils, and plates not further worked than hot-rolled or cold-rolled. Note: 7225 does not include stainless steel (classified under 7219-7220) or high-speed steel (confirmation required before classifying under 7225). Under this heading, products are further subdivided by processing state (hot-rolled, cold-rolled), coating (plated, painted), etc. Plated or coated products are classified under the corresponding subheadings of 7225, such as electro-galvanized, aluminum-coated, etc. Code 722592 consists of 6 digits. The first 2 digits "72" represent Chapter 72: Iron and steel. Digits 3-4 "25" represent heading 7225: flat-rolled products of other alloy steel, of a width of 600 mm or more. Digits 5-6 "92" represent subheading 7225.92: flat-rolled products of other alloy steel, of a width of 600 mm or more, not further worked than hot-rolled or cold-rolled, but plated or coated, with a coating of aluminum or aluminum alloy (aluminum-coated). Note: Subheading 7225.92 specifically refers to "aluminum-plated" or "aluminum-coated," including aluminum-silicon alloy coatings, etc. The complete code 722592 refers to "aluminum alloy coated steel sheet," meaning wide sheet made of other alloy steel (not stainless steel, not high-speed steel) with a surface coating of aluminum or aluminum alloy. The product is an alloy steel sheet (not stainless steel), of a width of 600 mm or more, with an aluminum surface coating. For classification, first determine the chapter (Chapter 72: Iron and steel), then determine the heading: since it is a flat-rolled product of alloy steel with a width of 600 mm or more, it is classified under 7225. Then, based on processing state: it has been coated beyond hot-rolling/cold-rolling, and the coating is aluminum, so it is classified under subheading 7225.92. If the coating were zinc, it would be classified under 7225.91; if it were another coating, under 7225.99. If the width were less than 600 mm, it would be classified under 7226. Therefore, 722592 accurately corresponds to aluminum alloy coated steel sheet.

🎯 Classification Logic
Core basis for classification: 1) Material is alloy steel (not stainless steel, not high-speed steel); 2) Flat-rolled product, width 600 mm or more; 3) Coated beyond hot-rolling or cold-rolling, with a coating of aluminum or aluminum alloy. According to the Import and Export Tariff and its notes, subheading 7225.92 explicitly includes aluminum-plated or aluminum-coated alloy steel wide sheet. If the width is less than 600 mm, classify under 7226; if the coating is zinc, classify under 7225.91; if it is another coating (such as tin or chromium), classify under 7225.99. 722591 Electro-galvanized alloy steel sheet: The coating is zinc (electro-galvanized), whereas 722592 has an aluminum coating. They can be distinguished by coating material testing. 722599 Other coated alloy steel sheet: The coating is another metal (such as tin, chromium, or nickel) or a non-metallic coating, excluding aluminum. 722540 Hot-rolled alloy steel sheet (uncoated): Hot-rolled only, not plated or coated, with no aluminum coating on the surface. 722550 Cold-rolled alloy steel sheet (uncoated): Cold-rolled only, not plated or coated, with no aluminum coating on the surface. 721061 Aluminum-zinc alloy coated steel sheet (non-alloy steel): The material is non-alloy steel, and the coating is aluminum-zinc alloy, classified under 7210, not 7225. Confirm whether the material is alloy steel (not stainless steel)? Confirm whether the width is 600 mm or more? Confirm whether it has been coated, and the coating is aluminum or aluminum alloy? Confirm whether there is no processing other than hot-rolling/cold-rolling? Confirm whether it is not high-speed steel?
