Chapter 84 is the core chapter in the HS classification covering machinery, mechanical appliances and their parts, including power machinery, agricultural machinery, processing machine tools, office equipment, automatic data processing equipment, lifting and handling machinery, etc. This chapter emphasizes the mechanical function and power-driven characteristics of goods, and the classification of parts must follow the principle of being used in conjunction with complete machines. As heavy industrial equipment, mineral processing machinery and its parts are also classified in this chapter. Heading 8474 covers machinery for working earth, stone, ores or other solid mineral substances (including powders or pastes), such as crushing, grinding, screening, sorting, mixing, molding and other equipment. Machines under this heading are mainly used in building materials, ore dressing, chemical raw material processing and other fields. Their parts, if not more specifically named in other headings, are classified under the subheading of 8474. Code 847490 consists of 6 digits. The first 2 digits 84 indicate Chapter 84 (machinery, mechanical appliances and parts); digits 3-4, 74, indicate heading 8474 (mineral processing machinery); digits 5-6, 90, indicate subheading 8474.90, i.e., parts specially or principally used for machines under 8474. Note: subheading 90 is a parts-specific subheading, distinct from the complete machine subheadings 8474.10 to 8474.80. If the part itself is an independent good named in another heading (such as bearings, motors), it is not classified under this code. This commodity is a part of a mineral processing machine. Since the complete machine is classified under 8474 and the part is not more specifically named in other headings of Chapter 84 or Chapters 82, 73, etc., it is classified as a dedicated part under 8474.90. If the part is a general-purpose part (such as bolts, gears), it may be classified under Chapter 73 or other headings of Chapter 84; if the part is an electrical component, it may be classified under Chapter 85. Therefore, only parts exclusively used for 8474 machines are classified under this code.

🎯 Classification Logic
The core basis for classification is whether the part is exclusively used for machines under 8474. According to Note 2 to Chapter 84, if a part is a good named in another heading, it should be classified under that heading; otherwise, parts exclusively used for machines of a certain heading are classified under that machine heading. Therefore, if a mineral processing machine part is not named in another heading and is exclusively used for 8474 machines, it is classified under 8474.90. At the same time, it is necessary to consider whether the part constitutes the essential character of a complete machine; if it already constitutes a complete machine, it should be classified under the complete machine subheading. 847410 Sorting, screening, separating or washing machines: 847410 is a complete machine subheading, while 847490 is a parts subheading. If a complete machine is imported, it should be classified under 847410; if it is only a part of that machine, it is classified under 847490. 847420 Crushing or grinding machines: 847420 is a complete crushing or grinding machine, and its dedicated parts are classified under 847490. Note: Parts such as jaw plates and hammers of crushers are classified under 847490, while the complete machine is classified under 847420. 847480 Other mineral processing machines: 847480 covers complete mineral processing machines not elsewhere specified, such as mixing and molding machines. Their dedicated parts are also classified under 847490, but it is necessary to confirm whether the complete machine is classified under 847480. 848790 Other machinery parts: 848790 is for general-purpose parts of other headings of Chapter 84. If the part is not exclusively used for 8474 machines, or can be classified under other headings, it may be classified under 848790. However, 847490 takes precedence over 848790. 732690 Other articles of iron or steel: If the part is a general-purpose iron or steel article, such as a simple bracket or gasket, and is not exclusively used for 8474 machines, it may be classified under 732690. However, if it is exclusively used for 8474 machines, it is still classified under 847490. Is the part exclusively used for machines under 8474? Is the part more specifically named in another heading? Does the part already constitute the essential character of a complete machine? Is sufficient proof of specificity provided? Are the material and use declared accurately?

❓ FAQ
How to determine whether a part is exclusively used for 8474 machines? Parts exclusively used for 8474 machines are usually designed so that they can only be used for machines under that heading and cannot be used universally for other machinery. This can be proven through technical drawings, applicable machine model descriptions, industry standards, etc. If the part is universal, it may be classified under other headings. Under which code should general-purpose parts of mineral processing machines, such as bolts and bearings, be classified? General-purpose parts such as bolts are classified under 7318, and bearings under 8482, not under 847490. This is because Note 2 to Chapter 84 stipulates that if a part is a good named in another heading, it should be classified under that heading. How are parts supplied with a complete machine classified when the complete machine is imported? If the parts are imported together with the complete machine and form the complete function of the machine, they are usually classified together with the complete machine. If the parts are separately packaged and used for after-sales repair, they should be classified separately. The specific case needs to be judged according to the actual situation. If a part under 847490 is composed of multiple components, how should it be declared? If multiple components are combined into one dedicated part, it is classified as a whole according to that part. If each component can be used independently, they should be classified separately. When declaring, the combination state and function need to be described in detail. How to check the import tax rate for 847490? Tax rates may change. It is recommended to check the latest tax rate through the official website of the General Administration of Customs, China International Trade Single Window, or professional databases. At the same time, attention should be paid to additional taxes such as free trade agreement rates and anti-dumping duties. What should be noted when exporting parts under 847490? When exporting, it is necessary to confirm whether the parts involve export controls, such as dual-use items. At the same time, accurate declaration elements must be provided for customs statistics and supervision. Some countries may require a certificate of origin. If a part can be used for both 8474 machines and other machines, how should it be classified? If a part can be used universally for multiple machines, it cannot be regarded as a dedicated part and should be classified according to its own properties. For example, if it is an iron or steel article, it is classified under Chapter 73; if it is a machinery part, it is classified under other headings of Chapter 84. What is the difference between 847490 and 84749000? 847490 is a 6-digit subheading, and 84749000 is an 8-digit tariff number, with the latter being a subdivision of the former. In Chinese customs declaration, a 10-digit code is usually used, but the core classification basis is the 6-digit subheading. The specific declaration needs to be determined according to the national code.
