Chapter 73 covers iron and steel articles, including tubes, profiles, plates, wire rods and other steel materials and their products, but excludes iron and steel waste and scrap (Chapter 72) and specific machinery, vehicles, etc. (Chapters 84-87). This chapter ranges from 7301 to 7326, covering various steel structural parts, containers, household utensils, etc. Welded angle steel, as a typical representative of steel profiles, belongs to the basic material category of products in this chapter. Heading 7301 specifically covers angles, shapes and sections of iron or steel, whether or not drilled, punched or bent, but excludes welded steel tubes (7305) or hollow profiles (7306). This heading covers angles formed by hot rolling, cold rolling, extrusion or welding, among which welded angle steel refers to angles formed by joining steel strip or steel plate through a welding process, as distinguished from products formed by integral hot rolling. Code 730120 is a six-digit subheading: the first two digits 73 represent Chapter 73, iron and steel articles; digits 3-4, 01, represent heading 7301, namely angles, shapes and sections of iron or steel; digits 5-6, 20, represent subheading 730120, specifically welded angle steel. Specifically, heading 7301 is divided into multiple subheadings, such as 730110 for sheet piling, 730120 for welded angle steel, and 730130 for other angles, shapes and sections (not welded). Therefore, this code precisely points to angle steel products produced through a welding process. Welded angle steel is classified under 730120 because its core characteristic is being welded and formed, and it falls within the category of angle steel. If it is an integrally hot-rolled angle, it should be classified under 730130; if it is a hollow profile or steel tube, it should be classified under 7305 or 7306. The key to classifying welded angle steel lies in its manufacturing process (welding) and cross-sectional shape (angle), rather than subsequent processing or use, so 730120 is the only corresponding code.

Product name: The Chinese and English names of the declared commodity must be consistent with the contract and invoice. It should be clearly stated as "welded angle steel" or "Welding angle steel"; avoid using colloquial names. Material: Fill in the steel grade and chemical composition, such as Q235B, SS400, etc., indicating that it is iron or non-alloy steel. It must be consistent with the quality inspection report. Specifications and dimensions: Declare the cross-sectional dimensions of the angle steel, such as side width × side width × thickness (unit: mm), as well as length. For example, "50×50×5mm, length 6m". Processing technology: Clearly state "welded and formed"; whether further processing has been carried out (such as drilling or bending) may be added. Welded angle steel is usually continuously welded from steel strip. Surface treatment: Describe the surface condition, such as black surface, galvanized, painted, etc. If untreated, declare "not surface-treated" or "black surface". Use: Explain the main use, such as building structures, machinery manufacturing, bridges, etc. Use does not affect classification, but it must be declared truthfully. Brand: Fill in the manufacturer or brand; if there is no brand, declare "no brand". It must be consistent with the packaging markings. Model: If there is a specific model, fill it in according to the contract; if there is no model, declare "no model". Customs declaration example: Product name: Welding angle steel Material: Non-alloy steel Q235B Specifications: 50×50×5mm, length 6000mm Processing technology: Welded and formed, not further processed Surface treatment: Black surface Use: For building structures Brand: No brand Model: No model HS code: 7301200000 Failure to indicate the "welding" process, resulting in classification under 730130 (other angles). Incomplete specifications and dimensions, lacking thickness or length, affecting customs documentary review. False declaration of surface treatment, such as declaring black surface when actually galvanized, may involve classification or anti-dumping issues.

The core basis for classification is the Import and Export Tariff and the Explanatory Notes to the Harmonized Commodity Description and Coding System. Subheading 730120 is explicitly "welded angle steel", referring to products formed by joining steel strip or steel plate into an angle shape through a welding process. When determining, attention should be paid to: 1) whether the cross-section is an angle (L-shaped); 2) whether it is formed by welding rather than hot rolling or cold bending; 3) whether it has undergone further processing (such as drilling or bending); if it is only welded and formed, it is still classified under 730120. If it is a hot-rolled angle, it is classified under 730130; if it is a hollow profile, it is classified under 7306. 730130 Other angles, shapes and sections: 730130 covers non-welded angles, such as hot-rolled or cold-formed angles. The key difference lies in the manufacturing process: welded angles are classified under 730120, and non-welded ones under 730130. 730630 Other welded steel tubes: 730630 is welded steel tube with a circular cross-section, while 730120 is angle steel (L-shaped cross-section). Cross-sectional shape is the core difference. 730690 Other welded hollow profiles: 730690 is welded non-circular hollow profiles (such as square tubes and rectangular tubes), while 730120 is solid angle steel. Hollow versus solid is the distinguishing point. 721699 Other angles, shapes and sections of iron or non-alloy steel: 721699 is angles of iron or non-alloy steel, but belongs to Chapter 72 and is usually semi-finished or not further processed, while 730120 is an article of Chapter 73 and may have undergone processing such as welding. Confirm whether the cross-section is an L-shaped angle. Confirm whether it is formed by a welding process. Confirm whether it has undergone further processing (such as drilling or bending). Confirm whether the material is steel (non-alloy or alloy). Confirm whether it is a hollow steel tube or profile.

What is the difference in HS codes between welded angle steel and hot-rolled angle steel? Welded angle steel is classified under 730120, and hot-rolled angle steel under 730130. The difference lies in the manufacturing process: welded angle steel is made by welding steel strip or steel plate, while hot-rolled angle steel is formed by hot rolling in a rolling mill. The process must be clearly declared; otherwise, classification errors may result. How can I check the import tax rate for 730120? Tax rates are adjusted according to national policies. It is recommended to check the latest tax rate through the official website of the General Administration of Customs or China International Trade Single Window. Enter HS code 730120 to view import tariffs, value-added tax and possible anti-dumping duties. You may also consult a professional customs broker. In the declaration elements for welded angle steel, how should specifications and dimensions be written? Specifications and dimensions should include side width, side thickness and length, for example, "50×50×5mm, length 6000mm". If it is an unequal angle, the widths of both sides must be indicated, such as "75×50×5mm". Ensure consistency with the actual goods and avoid vague descriptions. Both 730120 and 730630 involve welding. How are they distinguished? 730120 is welded angle steel with an L-shaped cross-section; 730630 is welded circular steel tube with a circular cross-section. When classifying, look at the cross-sectional shape: angles are classified under 730120, and round tubes under 730630. If it is a square tube or rectangular tube, it is classified under 730690. Will the HS code change after welded angle steel is galvanized? No. Galvanizing is a surface treatment and does not change the basic characteristics or classification. Even if galvanized, welded angle steel is still classified under 730120. However, "galvanized" must be indicated in the declaration elements for customs review. What should be noted when exporting welded angle steel to the EU? Attention should be paid to the EU's anti-dumping measures and quota restrictions on steel products. Check the EU TARIC database to confirm whether anti-dumping duties are involved. At the same time, ensure compliance with requirements such as CE certification. It is recommended to confirm specific regulations with the importer. Is the classification of welded angle steel affected by length? No. Regardless of length, as long as the cross-section is an angle and it is welded and formed, it is classified under 730120. However, if it is cut to a specific length and further processed into structural parts, it may be classified under subsequent headings such as 7308. If the welded angle steel is made of alloy steel, is the code still 730120? No. 730120 applies only to welded angle steel of non-alloy steel. Alloy steel angles should be classified under headings such as 7228 or 7229. Judgment must be based on material composition; for the definition of alloy steel, see the notes to Chapter 72.
