Chapter 73 covers articles of iron or steel, including tubes, plates, profiles and other semi-finished and finished products, but excludes machinery, vehicles, ships and other transport equipment of iron or steel (classified in Chapters 84-89). The core of this chapter is general-purpose iron or steel parts and daily metal products, such as structural components, containers, radiators, sanitary ware, etc. Heading 7322 covers iron or steel central heating radiators and parts thereof, as well as iron or steel air heaters and hot air distributors (non-electric). It includes cast iron or steel radiators, whether or not fitted with accessories, but electric radiators are classified in Chapter 85. First 2 digits 73 = Chapter for articles of iron or steel; digits 3-4 = 22 = heading 7322, referring to non-electric iron or steel central heating radiators and parts thereof, air heaters, etc.; digits 5-6 = 11 = subheading 732211, specifically referring to cast iron radiators and parts thereof. Note: 732211 is limited to cast iron only, while steel radiators should be classified under 732219 (other radiators of iron or steel). The 'steel radiator' provided by the user should actually be classified under 732219, but this analysis is conducted according to the user-specified code 732211, which requires special explanation. This commodity is a steel radiator for central heating, non-electric, so it is classified under 7322. However, 732211 specifically refers to cast iron, and steel should be classified under 732219. If electric, it would be classified under 8516. When classifying, it is necessary to first distinguish the material (cast iron/steel) and the heating method (central heating/electric).

Common Mistakes：
Mistakenly classifying steel radiators under 732211 (cast iron), when they should actually be classified under 732219.
Failing to distinguish central heating from electric heating; electric radiators should be classified under 8516.
False declaration of material, such as declaring cast iron as steel, which affects classification.
🎯 Classification Logic
Core basis for classification: 1) Material: cast iron or steel; 2) Use: central heating; 3) Heating method: non-electric. 732211 applies only to cast iron radiators and parts thereof; steel radiators should be classified under 732219. If electric, they are classified under 8516. 732219 Other radiators of iron or steel: Applies to steel radiators that are not cast iron; the material is steel, whereas 732211 specifically refers to cast iron. 851629 Electric radiators: Electric radiators are heated by electrical energy and are classified in Chapter 85, not Chapter 73. 732290 Other air heaters: 732290 includes non-electric air heaters, but radiators specifically refer to those used for central heating. 732181 Cast iron sanitary ware: 732181 refers to cast iron sanitary ware, such as bathtubs, which have a different use from radiators. Is the material cast iron or steel? Is it used for central heating? Is it non-electric? Is it a complete unit or a part? Does it have electric heating elements?

❓ FAQ
Why can't steel radiators be classified under 732211? Subheading 732211 explicitly refers to 'cast iron radiators and parts thereof'. Steel radiators do not match the material and should be classified under 732219 'Other radiators of iron or steel'. Material is the primary distinguishing factor in classification. How to distinguish central heating radiators from electric radiators? Central heating radiators are heated by circulating hot water or steam and have no electric heating elements, so they are classified under 7322; electric radiators have built-in electric heating elements and are classified under 8516. The working principle must be stated during declaration. How are radiator parts classified? If the parts are exclusively for cast iron radiators, they are classified under 732211; if exclusively for steel radiators, under 732219; if they are general-purpose parts, they are classified under other headings according to material. What is the tax rate for HS code 732211? Tax rates vary by country, trade agreement and period. It is recommended to check the latest tariff schedule of the customs administration or use an official query system, such as China Customs HS code query platform. What are the precautions for filling in material during declaration? It must be clearly stated whether it is cast iron or steel, and the grade must be indicated. If it is alloy steel, the composition must be provided. Incorrect declaration may lead to classification errors and customs penalties. Does a radiator with a thermostatic valve affect classification? If the thermostatic valve is manual, it does not affect classification; if it is automatic and electrically controlled, it may give the radiator an electric heating function, and classification needs to be re-evaluated. How to declare imported used radiators? Used radiators need to declare product name, material, use, working principle, etc., and may require inspection and quarantine certificates. The classification principles are the same as for new radiators. How to check the regulatory conditions for radiators? You can check the regulatory conditions corresponding to the HS code through the customs administration official website or the 'Single Window', such as whether a license, inspection and quarantine are required.
