Chapter 72 covers raw materials for iron and steel smelting, primary products, and certain semi-finished products, including pig iron, ferroalloys, scrap, steel ingots, semi-finished products (such as billets and slabs), as well as certain rolled or extruded bars, rods, angles, shapes, and sections. However, it should be noted that further processed products (such as cold-drawn or coated) or steel products of specific shapes may be classified under Chapter 73. This chapter is the core chapter for the classification of iron and steel products. Heading 7228 covers bars and rods of other alloy steel (other than hot-rolled coils of 7227), angles, shapes and sections, and hollow drill steel. Specifically, it includes: alloy steel bars (not in coils), alloy steel angles, alloy steel shapes and sections, alloy steel profiles, and alloy steel hollow drill steel. However, it does not include alloy steel wire rod (7227), alloy steel plates and sheets (7225/7226), or further processed products (such as cold-drawn or polished, which may be classified under 7228 or Chapter 73). The first 2 digits, 72, represent the chapter on iron and steel, covering all iron and steel materials. Digits 3-4, 28, represent heading 7228, i.e., bars and rods, angles, shapes and sections of other alloy steel. Digits 5-6, 30, represent subheading 722830, specifically alloy steel angles, i.e., alloy steel angles with an L-shaped, V-shaped, or similar angular cross-section, not further worked than hot-rolled, hot-drawn, or extruded. Note: if the angles have been cold-worked, coated, or further processed, they may be classified under other subheadings or Chapter 73. The product is an alloy steel angle with an angular cross-section, made of alloy steel (not stainless steel), and in hot-rolled or extruded condition. Therefore, it is classified under 7228.30, rather than 7228.70 (alloy steel shapes and sections) or 7228.40 (alloy steel profiles). If it were a stainless steel angle, it would be classified under 7222; if it were an ordinary steel angle, it would be classified under 7216.

Ignoring alloying element content; if the alloying elements are below the specified values, the product may be classified as ordinary steel angles under 7216.

🎯 Classification Logic
Core basis for classification: First confirm that the material is alloy steel (not stainless steel), meeting the definition of alloy steel in the notes to Chapter 72 (containing a certain amount of alloying elements). Second, confirm that the shape is an angle (cross-section L-shaped, V-shaped, etc.) and that it is in hot-rolled or extruded condition. If further processed (such as cold-drawn, polished, or coated), it may be classified under other subheadings of 7228 or Chapter 73. At the same time, stainless steel angles (7222) and ordinary steel angles (7216) must be excluded. 722870 Other alloy steel shapes and sections: 722870 covers alloy steel shapes and sections (such as H-shaped, I-shaped, etc.), while 722830 specifically covers angles (L-shaped, V-shaped). Cross-sectional shape is the key distinction. 722840 Other alloy steel profiles: 722840 covers profiles (non-standard cross-sections), while angles are a specific standard shape and should be classified under 722830. 722220 Stainless steel angles: 722220 covers stainless steel angles, made of stainless steel (containing chromium ≥10.5%), while 722830 covers angles of other alloy steel. 721610 Ordinary steel angles: 721610 covers angles of ordinary steel (non-alloy steel), while 722830 covers alloy steel angles. Material composition is the key distinction. 722880 Alloy steel hollow drill steel: 722880 covers hollow drill steel used for mining drilling, with a hollow cross-section, completely different from angles. Is the material alloy steel? Does the alloying element content comply with the notes to Chapter 72? Is the cross-sectional shape an angle (L-shaped, V-shaped, etc.)? Is the processing method hot-rolled, hot-extruded, or hot-drawn? Has it been cold-worked or coated? Are stainless steel angles (7222) and ordinary steel angles (7216) excluded? Are alloy steel wire rod (7227) and alloy steel plates and sheets (7225/7226) excluded?

❓ FAQ
How do I determine whether my angle steel is alloy steel? According to the notes to Chapter 72, alloy steel must contain a certain amount of alloying elements (such as chromium, nickel, molybdenum, vanadium, etc.) exceeding specified thresholds. For details, refer to GB/T 13304 or the grade specified in the contract. If uncertain, send samples to a laboratory for alloy composition testing. How are alloy steel angles and alloy steel shapes and sections distinguished during declaration? Angles have L-shaped, V-shaped, or similar angular cross-sections, while shapes and sections are usually H-shaped, I-shaped, U-shaped, etc. During declaration, provide a cross-sectional diagram or detailed description for accurate customs classification. If the cross-section is angular, it should be classified under 722830. If alloy steel angles have been cold-drawn, can they still be classified under 722830? No. 722830 only applies to angles in hot-rolled, hot-extruded, or hot-drawn condition. If further processed by cold-drawing, cold-rolling, etc., they should be classified under other subheadings of 7228 (such as 722860) or Chapter 73. The specific classification depends on the processing technique. Why is it necessary to provide alloying element content in the declaration elements for alloy steel angles? Because the definition of alloy steel depends on the content of alloying elements. Customs needs to verify whether it meets the alloy steel standard to determine whether it is classified under 7228 or 7216. Providing specific content can speed up customs clearance and avoid classification disputes. How can I check the applicable tariff rate when importing alloy steel angles? You can visit the website of the General Administration of Customs of China or use the "Customs Classification Pre-ruling" system, enter HS code 722830 to query the latest rate. Rates may vary due to trade agreements, country of origin, and other factors; it is recommended to refer to official publications. What is the export tax rebate rate for alloy steel angles? The export tax rebate rate should be determined according to the latest documents from the State Taxation Administration. It can usually be queried through the "China Export Tax Rebate Consulting Network" or the electronic tax bureau. Note that rebate rates may be adjusted; it is recommended to refer to the policy at the time of declaration. If alloy steel angles are used for building structures, what should be noted during declaration? Indicate the use as "for building structures" and provide relevant standards (such as GB/T 706). If used in special fields (such as bridges or ships), other regulatory conditions may apply and should be confirmed in advance. Could the HS code for alloy steel angles be classified under Chapter 73? If the angles have been further processed (such as drilled, galvanized, or plastic-coated), they may be classified under Chapter 73 (such as 7308 steel structures). However, if they are only hot-rolled angles, they remain classified under 722830. The specific classification depends on the degree of processing.
