Chapter 84 is the core chapter in HS classification covering machinery and mechanical appliances, including power machinery, agricultural machinery, 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, rather than mere materials or uses. As for crushers, they crush materials through mechanical force and are typical processing machinery, thus classified under this chapter. Heading 8474 covers machines for sorting, screening, separating, washing, crushing, grinding, mixing or kneading earth, stone, ores or other solid (including powder or paste) mineral substances; and machines for forming foundry molds of sand. Crushers, as equipment for crushing large materials into small pieces, fully conform to the description of this heading, thus classified under 8474. The first 2 digits 84 represent Chapter 84, i.e., machinery and mechanical appliances and parts thereof. The 3rd-4th digits 74 constitute heading 8474, specifically referring to machines for processing solid mineral substances such as earth, stone, ores, including crushing, grinding, screening, mixing, etc. The 5th-6th digits 20 are the subheading; under 8474, 8474.20 specifically refers to crushing or grinding machines. Therefore, 847420 fully represents "crushing or grinding machines," of which crushers are a typical representative. Crushers are used to crush solid mineral materials, and their core function is crushing, not screening, separating or mixing. Subheading 8474.20 explicitly includes crushing or grinding machines, thus classified under this code. Adjacent codes such as 8474.10 for screening and separating machines, and 8474.31 for concrete or mortar mixing machines, have different functions and therefore do not apply.

Product Name: The specific name of the declared commodity, such as "jaw crusher," "cone crusher," etc., which must be consistent with the actual product. Use: Explain the industry or scenario where the crusher is applied, such as mining crushing, construction waste processing, etc. Working Principle: Briefly describe the crushing method, such as extrusion, impact, grinding, etc., to distinguish different types. Brand: Fill in the manufacturer or brand name; if no brand, write "no brand." Model: Fill in the model assigned by the manufacturer for unique identification of the equipment. Power: Main motor power, in kilowatts (kW), reflecting equipment specifications. Processing Capacity: Amount of material processed per unit time, such as tons/hour, reflecting equipment performance. Product Name: Jaw Crusher; Use: For primary crushing of ore in mines; Working Principle: Periodically squeezing material through movable jaw plate; Brand: Sandvik; Model: JM1208; Power: 110kW; Processing Capacity: 200 tons/hour. Failure to distinguish crushing from grinding, leading to subheading errors. Classifying crushers under 8479 other machinery, ignoring the specific listing under 8474. Incomplete declaration elements, such as missing working principle or processing capacity.

The core basis for classification is the function of the machine: whether it is used for crushing solid mineral substances. 8474.20 explicitly covers crushing or grinding machines, so as long as the equipment's main function is crushing, it is classified under this subheading. Note that if the equipment has both crushing and screening functions, it should be classified according to the main function; if it is a part of a crusher, it is classified under 8474.90. 847410 Sorting, screening, separating or washing machines: 847410 is used for sorting and separating materials, such as vibrating screens, while 847420 is used for crushing, with different functions. 847431 Concrete or mortar mixers: 847431 is used for mixing, such as concrete mixers, while 847420 is used for crushing, with completely different functions. 847490 Parts of machines of heading 8474: 847490 covers dedicated parts of machines such as crushers, e.g., crushing walls, jaw plates, while complete machines are classified under 847420. 847982 Mixing, kneading machines: 847982 is used for mixing and stirring chemical materials, while 847420 is used for mineral crushing, with different materials and functions. Is the equipment's main function crushing? Is it used for solid mineral substances? Does it include screening or mixing functions? Is it a complete machine rather than a part? Does it belong to other subheadings under 8474?

Why are crushers classified under 847420 instead of 8479? 8479 is a residual heading for machinery not elsewhere specified, while 8474 explicitly lists crushing machines, and subheading 847420 specifically targets crushing or grinding machines, so 847420 is preferred. How are mobile crushing stations classified? If a mobile crushing station has crushing as its main function, it is still classified under 847420 even if mounted on a chassis or tracks; however, if it has other functions, classification should be based on the main function. Which code should crusher parts be classified under? Dedicated parts of crushers, such as jaw plates, crushing walls, hammers, etc., should be classified under 847490, not the complete machine code 847420. How to distinguish between crushers and grinding mills? Crushers typically crush materials to a few millimeters to tens of millimeters, while grinding mills grind materials to micron level. However, HS code 847420 covers both, so no distinction is needed. What are common errors in declaration? Common errors include: general product names, failure to provide working principle, incorrect power units, and misclassifying crushers under 8479 or other subheadings of 8474. What certifications are required for crusher exports? Exports may require certifications such as CE, EPA, etc., depending on the destination country's requirements, but the HS code itself does not determine certification; specific regulations must be considered. How to check the tariff rate for 847420? Tariff rates must be checked based on the destination country and trade agreements. It is recommended to use customs tariff schedules or official databases, and note that rates may change. Are there special rules for classifying used crushers? Used crushers are still classified under 847420 based on function, but the declaration must indicate "used" and the condition rate; customs may conduct valuation.
