Chapter 84 is the chapter on mechanical appliances in the HS classification system, covering an extremely broad scope, including various power machinery, processing machinery, handling machinery, agricultural machinery, office machinery, etc. The core feature of this chapter is machines, mechanical appliances, devices and their parts, but it explicitly excludes certain specific types of machinery (such as electrical equipment of Chapter 85). Within the chapter, it is divided into multiple headings according to function or use, from boilers and engines to various types of special-purpose machinery, reflecting full-chain coverage from power sources to end-use applications. Heading 8474 covers machinery for working earth, stone, ores or other solid mineral substances (including powders or pastes), specifically including: screening, sieving, separating, washing, crushing, grinding, mixing or stirring machinery; and machines for agglomerating or molding these materials into shapes. Machines under this heading are widely used in building materials, chemicals, mining, ceramics and other industries, and the materials handled are solid mineral substances, not liquids or gases. Code 847439 consists of 6 digits. The first 2 digits "84" represent Chapter 84, namely nuclear reactors, boilers, machinery, mechanical appliances and their parts. The 3rd-4th digits "74" represent heading 8474, namely machinery for working earth, stone, ores or other solid mineral substances. The 5th-6th digits "39" represent subheading 8474.39, specifically "other mixing or stirring machines." Under heading 8474, subheadings are further divided by processing method: 8474.10 for screening, sieving, separating or washing machinery; 8474.20 for crushing or grinding machinery; 8474.31 for concrete or mortar mixers; 8474.32 for mixers for mixing mineral substances with bitumen; 8474.39 for other mixing or stirring machines; 8474.80 for other machinery; 8474.90 for parts. Therefore 847439 specifically refers to other mixing or stirring machines not elsewhere specified. This commodity is classified under 847439 because it is a mixing or stirring machine for processing solid mineral substances, but it is neither a concrete or mortar mixer (847431) nor a mixer for mixing mineral substances with bitumen (847432). As a residual subheading, 847439 covers other mixing or stirring equipment besides the above two specialized mixers, such as mixers used for ceramic raw materials, glass batch, chemical mineral powders, etc. If the mixer is used for mixing liquids or gases, it should be classified under 8479 for other machinery not elsewhere specified, rather than 8474.

Product name
The Chinese and foreign-language names of the declared commodity should be specific and clear, such as "double-shaft mixer," "powder mixer," etc., avoiding the vague term "mixer."
⚠️ Writing only "mixer" without distinguishing the specific type and use.
Use
Explain the type of material handled by the mixer and the industry it belongs to, such as "used for mixing ceramic raw materials," "used for stirring mineral powders," etc.
⚠️ The description of use is too broad, such as "industrial use," and does not reflect the characteristics of solid mineral processing.

⚠️ Failure to explain the working principle, making it impossible to determine whether it falls within the scope of 8474.
Brand and model
Fill in the manufacturer's brand and specific model to facilitate customs identification and classification.
⚠️ Missing brand and model or inconsistency with the actual goods.
Power
Main motor power, in kilowatts (kW), reflecting the equipment specifications.
⚠️ Incorrect power unit or failure to fill it in.

🎯 Classification Logic
The core criteria for classification are: 1) whether the machine is used for working earth, stone, ores or other solid mineral substances (including powders or pastes); 2) whether mixing or stirring is the core function of the machine; 3) whether it belongs to a type of mixer already named under heading 8474 (concrete or mortar mixers, mixers for mixing mineral substances with bitumen). If both 1 and 2 are satisfied, and it does not belong to a named type, it is classified under 847439. If the processed object is liquid or gas, or mixing is not the core function, other headings should be considered. 847431 Concrete or mortar mixers: 847431 specifically refers to mixers used for concrete or mortar, and the processed object is construction concrete or mortar; while 847439 covers other solid mineral mixers, such as ceramic raw materials, glass batch, etc. 847432 Mixers for mixing mineral substances with bitumen: 847432 specifically refers to mixing equipment for mixing mineral substances with bitumen, used for road paving; 847439 is used for other solid mineral mixing not involving bitumen. 847982 Other mixing, stirring, crushing, grinding, screening, homogenizing or emulsifying machines: 847982 belongs to heading 8479 and applies to processing liquids, gases or materials not elsewhere specified, while 847439 is limited to solid mineral processing. 847410 Screening, sieving, separating or washing machinery: 847410 is machinery for screening, separating, etc. of solid minerals and does not have a mixing function; 847439 is mixing machinery, with a different function. 847490 Parts: 847490 is parts for machines under heading 8474, while 847439 is a complete mixer; the two have a whole-machine-to-parts relationship. Is the processed object a solid mineral (powder, paste)? Is mixing the core function of the machine? Does it not belong to concrete or mortar mixers? Does it not belong to mixers for mixing mineral substances with bitumen? Is it not equipped with specific functions named under other headings?

❓ FAQ
How can it be determined whether a mixer should be classified under HS code 847439? First confirm whether the material handled by the mixer is earth, stone, ore or other solid mineral substances (including powders or pastes). Second, mixing must be the core function of the machine. Finally, exclude concrete or mortar mixers (847431) and mixers for mixing mineral substances with bitumen (847432). If all are satisfied, classify under 847439. What is the difference between 847439 and 847982? 847439 is specifically for mixers used in solid mineral processing and belongs to heading 8474; while 847982 is for other mixing and stirring machines under heading 8479 and applies to liquids, gases or materials not elsewhere specified. The key difference lies in the physical form of the processed object and the industry use. What declaration elements must be provided when declaring 847439? It is recommended to provide product name, use, working principle, brand and model, power, volume or processing capacity, CNC or not, etc. Among these, use and working principle are the most critical, as they are used to prove that the equipment is a solid mineral mixer. If a mixer can be used for both solid minerals and liquids, how should it be classified? It should be judged according to its main use and design characteristics. If it is mainly designed for solid minerals, classify under 847439; if it is mainly designed for liquids, classify under 847982 or another corresponding heading. If necessary, apply to customs for advance classification. How can the import tariff rate for 847439 be checked? Tariff rates vary by country, trade agreement, and annual adjustments. It is recommended to check the latest rates through the official website of the General Administration of Customs of China, the International Trade Single Window, or by consulting a professional customs broker. Also pay attention to whether additional duties such as anti-dumping or countervailing duties are involved. What regulatory documents are required to export 847439? Generally, exporting 847439 does not require special regulatory documents, but it must comply with the access requirements of the destination country. If dual-use items or technology exports are involved, corresponding licenses must be obtained. It is recommended to confirm with a customs broker in advance. Under which code should parts of 847439 be classified? Parts of machines under heading 8474 should be classified under 847490. However, note that if the part itself is an independent commodity named under another heading (such as motors, bearings), it should be classified under its corresponding heading. Can small mixers exported via cross-border e-commerce be classified under 847439? Yes, but they must meet the use requirement of solid mineral processing. If they are small household mixers (such as food mixers), they should not be classified under 847439, but rather under headings such as 8509 or 8479. Cross-border e-commerce requires accurate classification to avoid customs clearance risks.
