Chapter 84 covers nuclear reactors, boilers, machinery, mechanical appliances and their parts, and is the most important mechanical chapter in the HS. This chapter includes power machinery, agricultural machinery, metalworking machine tools, office equipment, automatic data processing equipment, lifting and handling machinery, bearings, seals, etc. Its core feature is that goods must have mechanical power drive or non-electric direct drive functions, and are mostly for industrial or engineering use. The notes to this chapter strictly define the scope, excluding electric tools (Chapter 85), vehicles (Chapter 87), etc. Heading 8474 is specifically for machines for sorting, screening, separating, washing, crushing, grinding, mixing or kneading earth, stone, ores or other solid (including powdered or paste) mineral substances; and machines for agglomerating, molding or shaping solid mineral fuels, ceramic pastes, unhardened cements, plastering materials or other powdered or paste mineral products; and machines for making sand molds. This heading focuses on machinery for processing mineral materials and does not involve metalworking or food processing. Code 847410 is a 6-digit subheading. The first 2 digits 84 represent Chapter 84 (machinery); digits 3-4, 74, represent heading 8474 (machines for sorting, screening, separating, washing, crushing, grinding, mixing or kneading minerals; molding machines); digits 5-6, 10, represent subheading 8474.10, namely sorting machines. This subheading specifically refers to equipment used to sort solid materials such as minerals and ores according to physical characteristics such as particle size, density, and color, such as vibrating screens, air classifiers, magnetic separators, etc. This commodity is a sorting machine, used to sort solid minerals such as ores and sand and gravel by particle size or density, which conforms to the functional description of heading 8474, 'sorting, screening, separating.' Its core function is sorting, not crushing (8474.20), mixing (8474.30), or molding (8474.80). At the same time, it does not belong to the residual machinery of 8479, because 8474 already explicitly covers such mineral processing machinery. Therefore, classification under 8474.10 is the most accurate.

Product name: The specific name of the declared commodity, such as 'vibrating sorting machine,' 'air classifier,' etc., which must be consistent with the actual goods. Use: Explain the industry and scenario in which the sorting machine is used, such as 'for ore sorting in mines,' 'for construction waste sorting,' etc. Working principle: Briefly describe the sorting mechanism, such as 'grading by particle size through a vibrating screen,' 'sorting by density using airflow,' etc. Brand: Fill in the manufacturer or brand name; if there is no brand, fill in 'no brand.' Model: Fill in the model specifications of the equipment, such as 'FX-2000.' Sorted material: Clearly specify the object to be sorted, such as 'iron ore,' 'quartz sand,' 'coal,' etc. Processing capacity: Fill in the equipment's processing capacity per hour, such as '50 tons/hour.' Product name: vibrating sorting machine; Use: used for grading iron ore by particle size in mines; Working principle: driven by an eccentric vibrating motor, the screen mesh causes materials to jump forward on the screen surface; material smaller than the screen openings falls through, while material larger than the screen openings is discharged from the discharge end; Brand: XX; Model: ZD-1230; Sorted material: iron ore; Processing capacity: 100 tons/hour. Mistakenly classifying sorting machines under 8479 (residual machinery), ignoring the explicit coverage of 8474. Incorrectly classifying sorting machines used for food or chemicals under 8474, when they should actually be classified according to material properties. Failure to provide the working principle at declaration, causing customs to be unable to determine whether it falls within the scope of 8474.

The core basis for classification is the notes to HS Chapter 84 and the text of heading 8474. 8474 explicitly includes 'sorting, screening, separating' machines and is directed at solid minerals. If a sorting machine is used for mineral processing, it is classified under 8474.10. If a sorting machine is used for other materials (such as food or plastics), it may be classified under 8438 (food processing) or 8479 (other machinery). At the same time, it is necessary to confirm whether the equipment has an independent function; if it is part of a production line, it should still be classified according to the main machine. 847420 Crushing or grinding machines: 847420 is for crushing and grinding, turning large pieces of material into small pieces or powder; 847410 sorting machines do not change material size, but only separate according to characteristics. 847490 Parts: 847490 is for dedicated parts of 8474 machines, such as screen meshes and liners; complete sorting machines are classified under 847410, and parts under 847490. 847982 Mixing or kneading machines: 847982 is used for mixing and kneading to make materials uniform; 847410 sorting machines are used to separate materials with different characteristics. 847989 Other machinery not elsewhere specified: 847989 is a residual code; if a sorting machine does not meet the definition of 8474 (for example, non-mineral processing), it may be classified here. 843880 Food processing machinery: 843880 is used for food processing, such as sorting fruit; if a sorting machine is used for food, it is classified under 8438 rather than 8474. Is the equipment used for sorting solid minerals? Is the sorting based on physical characteristics (particle size, density, etc.)? Does the equipment have an independent sorting function? Is it clearly distinguished from functions such as crushing and mixing? Have non-mineral uses such as food and chemicals been excluded?

A sorting machine is classified under 847410, but it is used for plastic recycling. Is that appropriate? Not appropriate. 847410 applies only to the sorting of minerals (earth, stone, ores, etc.). Plastic recycling sorting machines are usually classified under 8479 (other machinery not elsewhere specified), because plastics are not minerals. If a plastic sorting machine has a crushing function, it may need to be classified according to its main function. Must a vibrating screen always be classified under 847410? Not necessarily. If the vibrating screen is used for mineral screening, it is classified under 847410; if it is used for food, chemicals, etc., it is classified under 8438 or 8479 according to use. At the same time, if the vibrating screen is auxiliary equipment to a crusher, it may be classified together with the main machine. How are parts of sorting machines classified? Dedicated parts (such as screen meshes and vibration motors), if used for 8474 machines, are classified under 847490. However, if the parts themselves are general-purpose parts (such as bolts and bearings), they are classified according to material (such as 7318, 8482). What should be noted when declaring the import of used sorting machines? Used equipment requires a pre-shipment inspection certificate, and the declaration must indicate 'used' and the condition rate. At the same time, it is necessary to ensure that the equipment complies with national safety and environmental protection standards. Classification remains under 847410, but customs may conduct a valuation review. What is the difference in classification between sorting machines, magnetic separators, and flotation machines? Magnetic separators and flotation machines are both used for mineral sorting and are usually classified under 847410. However, if a magnetic separator is used for non-minerals (such as scrap steel sorting), it may be classified under 8479. If a flotation machine is used for chemicals, it is classified under 8479. How can I check the regulatory conditions for 847410? Regulatory conditions can be checked through the official website of the General Administration of Customs of China or the 'Import and Export Tariff of the People's Republic of China.' Usually, attention should be paid to whether it involves an O certificate (automatic import license) or A/B certificate (inbound/outbound goods customs clearance form). The latest tariff shall prevail. Can a sorting machine exported to ASEAN enjoy the agreement tariff rate? It is necessary to confirm whether the commodity is on the ASEAN agreement tariff list. Usually 847410 can enjoy the agreement tariff rate, but a certificate of origin (Form E) must be provided. The specific rate must be checked against the latest customs data. At declaration, how should the 'working principle' of a sorting machine be described? It should briefly and clearly explain the sorting mechanism, such as 'using a vibrating screen to grade by particle size,' 'using airflow to sort by density,' 'using magnetic force to attract ferromagnetic substances,' etc. Avoid writing simply 'sorting'; it should reflect the physical separation principle.
