Chapter 72 covers iron and steel and articles thereof, including pig iron, ferroalloys, direct reduced iron, ferrous waste and scrap, ingots, semi-finished products, flat-rolled products, bars, wire rods, angles, shapes, sections, tubes, hollow profiles, etc. This chapter is the basic classification of steel products, covering a wide range from raw materials to primary processed goods, but excluding further articles of subsequent chapters (such as Chapter 73 steel articles, Chapter 82 tools, Chapter 83 miscellaneous articles, etc.). Heading 7223 specifically covers stainless steel wire, i.e., wire of stainless steel made by drawing or extrusion processes, with a circular or other cross-section, whether or not further worked (such as coated, polished), but excluding products that have become recognizable articles (such as wire rope, barbed wire, etc., classified under 7312 or 7313). This heading is further subdivided according to composition, size, and processing state. The first 2 digits 72 represent Chapter 72 iron and steel; digits 3-4, 23, represent heading 7223, i.e., stainless steel wire; digits 5-6 are subheadings used to distinguish specific types. For example, 722300 is a 6-digit subheading, but in actual international codes it is often further subdivided into 7223.00.10 (circular cross-section, diameter >= 0.5 mm), 7223.00.90 (other), etc. Countries may further extend to 8-10 digits. Classification requires determining the specific subheading based on material, cross-sectional shape, size, processing state, etc. This commodity is stainless steel wire, which falls within the scope of steel wire rods, and the material is stainless steel, so it is classified under Chapter 72. Because it is a wire product, rather than flat-rolled, bar, or tube, it is classified under heading 7223, not 7222 (stainless steel bars) or 7220 (stainless steel flat-rolled products). If it were an article of stainless steel wire (such as wire rope or wire mesh), it might be classified under Chapter 73.

Product name: The standard name of the declared commodity, such as "stainless steel wire", which must be consistent with the actual goods and avoid colloquial or vague expressions. Material: Specific stainless steel grade, such as 304, 316, etc., which must comply with international or domestic standards and be supported by composition certificates. Cross-sectional shape: Describe the cross-sectional shape of the wire, such as circular, square, rectangular, etc.; for circular, the diameter must be indicated. Size: For circular wire, declare the diameter (mm); for non-circular wire, declare the cross-sectional dimensions (such as side length, width, thickness). Processing state: Such as cold drawn, annealed, quenched, tempered, coated, etc., which affects classification and tariff rates. Use: Briefly explain the main use, such as making springs, welding wire, woven mesh, etc., to assist classification. Grade standard: The applicable standard number, such as GB/T 4240, ASTM A580, etc., to ensure compliance with specifications. Simulated customs declaration: Product name: Stainless steel wire Material: 304 stainless steel Cross-sectional shape: Circular Size: Diameter 2.0 mm Processing state: Cold drawn, bright surface Use: Used for manufacturing springs Grade standard: GB/T 4240-2019 HS code: 722300 Declaration elements: 1. Product name: Stainless steel wire; 2. Material: 304; 3. Shape: Circular; 4. Size: Diameter 2.0 mm; 5. Processing: Cold drawn; 6. Use: Making springs; 7. Standard: GB/T 4240. Mistakenly classifying stainless steel wire under 7222 (bars), because the definitions of wire and bar are not distinguished (wire usually has a smaller diameter and is coiled). Ignoring the cross-sectional shape and declaring special-shaped wire as circular wire, resulting in an incorrect subheading. Failure to provide the stainless steel grade and writing only "stainless steel", which may require supplementation or raise doubts about classification.

Core basis for classification: 1) The material must be stainless steel (meeting the definition of steel containing >= 10.5% chromium); 2) The form is wire, usually coiled, with relatively small cross-sectional dimensions (generally diameter <= 13 mm); 3) The processing method is drawing or extrusion, and it may undergo subsequent treatment but has not become an article. If the wire has been made into an obvious article (such as wire rope or barbed wire), it is classified under Chapter 73. At the same time, reference must be made to the Import and Export Tariff and its notes to ensure the correct subheading division. 722220 Stainless steel bars: Bars are usually straight or coiled, but have a larger diameter (generally >= 13 mm) and are not made by drawing; while wire has a smaller diameter and is made by drawing. 722300 Stainless steel wire: This code is stainless steel wire, but attention must be paid to subheading subdivision: for example, 7223.00.10 is circular cross-section with diameter >= 0.5 mm, and 7223.00.90 is other. 731210 Wire rope: Wire rope is twisted from multiple strands of steel wire and has become an article, classified under 7312; while stainless steel wire is a single-strand wire. 731300 Barbed wire: Barbed wire is steel wire with barbs, used for protection, and is an article classified under 7313; while stainless steel wire is a raw material. 722990 Other alloy steel wire: 722990 covers wire of other alloy steel (non-stainless), such as silicon-manganese steel wire; while stainless steel wire must contain >= 10.5% chromium. Is the material stainless steel (chromium content >= 10.5%)? Is the cross-sectional shape clear? For circular, the diameter must be declared. Is the size within the wire range (generally diameter <= 13 mm)? Is the processing state declared? Such as cold drawn, annealed, etc. Has it already become an article? Such as wire rope, mesh, etc., which should be classified under Chapter 73.

How to query the HS code for stainless steel wire? First confirm that the material is stainless steel, then based on cross-sectional shape, size, processing state, etc., look up heading 7223 of Chapter 72 in the Import and Export Tariff. A customs classification database may be used or a customs broker consulted to ensure accuracy. What is the difference in classification between stainless steel wire and iron wire? Iron wire usually refers to low-carbon steel wire, classified under heading 7217; stainless steel wire is classified under 7223. The main difference is the material: stainless steel contains >= 10.5% chromium, while iron wire is ordinary carbon steel. If stainless steel wire is coated, will it affect classification? Generally it does not affect classification and it remains under 7223, but the coating type must be indicated in the declaration elements. If after coating it becomes an article (such as plastic-coated steel wire mesh), it may be classified under Chapter 73. Does the diameter of stainless steel wire affect the HS code? Yes, some countries further subdivide under the subheading, such as diameter >= 0.5 mm and < 0.5 mm. It must be declared according to the actual size to avoid subheading errors. What is the difference in HS codes between stainless steel wire and wire rope? Stainless steel wire is classified under 7223, and wire rope under 7312. Wire rope is twisted from multiple strands of steel wire and has become an article, so the classification is different. What are the common errors when declaring stainless steel wire? Common errors include: failure to indicate the stainless steel grade, confusing wire with bar, omitting size or shape, and mistakenly declaring an article as wire. It is recommended to provide detailed specifications and material certificates. How to query the tariff rate for stainless steel wire? Tariff rates may change. The latest rates can be obtained through the website of the General Administration of Customs, tariff query platforms, or by consulting a customs broker. Note that different subheadings and countries of origin may apply different rates. How can cross-border e-commerce sellers of stainless steel wire ensure compliance? They must accurately declare the HS code, provide elements such as material and size, and understand the regulatory conditions of the exporting and destination countries. It is recommended to work with a professional customs broker to avoid customs clearance issues.
