Chapter 84 is the core chapter in the HS classification covering machinery, mechanical appliances and their parts, including power machinery, agricultural machinery, metalworking machine tools, office equipment, automatic data processing equipment, lifting and handling machinery, etc. Goods in this chapter usually have power drive, moving parts or functional units, which distinguishes them from the electrical equipment of Chapter 85. As specialized equipment for pouring molten metal into molds, metal casting machines fall within the metalworking machinery category of this chapter. Heading 8479 covers machines and mechanical appliances having individual functions, not specified or included elsewhere in this chapter. This heading is a residual heading used to classify machines that cannot be classified under more specific headings of Chapter 84. If a metal casting machine is not specifically named under 8454 (converters, ladles, ingot moulds and casting machines, of a kind used in metallurgy or in metal foundries), it may be classified under 8479. However, it should be noted that subheading 847981 under 8479 explicitly covers metal casting machines, so actual classification should give priority to this subheading. Code 847981 consists of 6 digits: the first 2 digits 84 represent Chapter 84 (machinery, mechanical appliances and their parts); digits 3-4, 79, represent heading 8479 (machines and mechanical appliances having individual functions, not specified or included elsewhere in this chapter); digits 5-6, 81, represent subheading 847981, specifically metal casting machines. This subheading is a dedicated entry under 8479 for metal casting equipment, distinguishing it from other machines not elsewhere specified. The 5th digit 8 indicates a specific functional machine category under this heading, and the 6th digit 1 further specifies metal casting machines. Metal casting machines are classified under 847981 rather than the casting machines of 8454 because 8454 specifically refers to converters, ladles, ingot moulds and casting machines of a kind used in metallurgy or in metal foundries, mainly involving specific equipment for smelting and pouring. The metal casting machines of 847981 may refer to other casting equipment not elsewhere specified, such as continuous casting machines, centrifugal casting machines, etc. If the equipment has both smelting and casting functions, classification should be determined based on the principal function. When classifying, it is necessary to check the heading notes to ensure there is no overlap with 8454.

Use: Explain the application field of the equipment, such as for casting automotive parts, hardware components, etc. Working Principle: Briefly describe how the equipment achieves casting, such as gravity casting, low-pressure casting, centrifugal casting, etc. Brand: Fill in the equipment brand; if there is no brand, indicate 'no brand'. Model: Fill in the specific model of the equipment to identify specifications. Power: Fill in the rated power of the equipment (such as kilowatts), reflecting equipment energy consumption. Brand Type: Select 'foreign brand (OEM production)', 'foreign brand (other)' or 'domestic brand', etc. Export Preference Status: If for export, explain whether it enjoys export tax rebate or other preferences. Product Name: Metal Casting Machine; Use: For casting aluminum alloy automotive engine cylinder blocks; Working Principle: Low-pressure casting; Brand: ABC; Model: LCM-2000; Power: 75kW; Brand Type: Foreign brand (other); Export Preference Status: Not applicable. Mistakenly classifying die casting machines under 847981; die casting machines should be classified under 8454 or other subheadings of 8479. Failing to distinguish casting machines from pouring machines; pouring machines may be classified under 8454. Incomplete declaration elements, such as missing working principle or power, leading to classification disputes.

The core basis for classification is the notes to Chapter 84 of the Harmonized Commodity Description and Coding System and the notes to heading 8479. A metal casting machine must meet the following: 1) used for metal casting; 2) having an individual function; 3) not named under a more specific heading such as 8454. If the equipment is a die casting machine, it is usually classified under 8454; if it is a continuous casting machine or centrifugal casting machine, it may be classified under 847981. At the same time, reference should be made to the Explanatory Notes to the Import and Export Tariff for the interpretation of 8479 to ensure the equipment meets the 'not elsewhere specified' condition. 8454 Converters, ladles, ingot moulds and casting machines, of a kind used in metallurgy or in metal foundries: 8454 specifically refers to converters, ladles, ingot moulds and casting machines used in metallurgy and casting, mainly involving specific equipment for smelting and pouring; the metal casting machines of 847981 may refer to other casting equipment not elsewhere specified, such as continuous casting machines. 8479.82 Mixing, kneading, crushing, grinding, screening, sifting, homogenising, emulsifying or stirring machines: 847982 is used for mixing, stirring and similar machines, which have different functions from casting machines. If a casting machine is equipped with a sand mixing function, classification should be based on the principal function. 8479.89 Other machines and mechanical appliances: 847989 is another subheading under 8479; if a metal casting machine does not meet the specific description of 847981, it may be classified under this subheading. However, 847981 is explicitly named and should take priority. 8462 Machine tools for working metal: 8462 covers machine tools for forging, stamping, shearing, etc., which are different from casting machines. Casting is liquid forming, while 8462 is solid processing. 8514 Industrial or laboratory furnaces and ovens: 8514 includes metal heat treatment furnaces, etc. If a casting machine is equipped with a melting furnace, they should be classified separately: the melting furnace under 8514 and the casting machine under 847981. Is the equipment used for metal casting? Is it not specifically named under 8454? Does it have an individual function? Does it belong to other machines not elsewhere specified under 8479? Are the declaration elements complete and accurate?

How are metal casting machines and die casting machines distinguished in HS codes? Metal casting machines usually refer to gravity casting, low-pressure casting and similar equipment, classified under 847981; die casting machines belong to pressure casting and are generally classified under 8454 (die casting machines used in metal casting) or other subheadings of 8479. The key difference lies in the casting method: die casting injects molten metal into a mold under high pressure, while ordinary casting relies on gravity or low pressure. A working principle description must be provided during customs declaration. If a metal casting machine has a melting furnace, how should it be classified? If the melting furnace and casting machine are combined into one unit, classification should be based on the principal function. If melting is the principal function, it may be classified under 8514; if casting is the principal function, it should be classified under 847981. If they are separate equipment, they should be classified separately. It is recommended to refer to the classification rules for composite machines in the Tariff Explanatory Notes. In the declaration elements of 847981, is power mandatory? Power is an important declaration element used for customs statistics and classification reference. If the equipment has no power parameter, 'none' or 'not applicable' may be filled in, but it is recommended to provide rated power. Omitting it may lead to incomplete declaration and affect customs clearance. Can imported used metal casting machines be classified under 847981? Yes, but it should be noted that the import of used mechanical and electrical products must comply with national regulations and may involve pre-shipment inspection. The classification itself remains unchanged, but documents such as import licenses for used mechanical and electrical products must be provided. When declaring, indicate 'used' and explain in the remarks. How can I check the import tax rate for 847981? Tax rates change; it is recommended to check the latest Import and Export Tariff through the official website of the General Administration of Customs of China or the 'Single Window'. Customs classification advance ruling services may also be used to confirm the code. Note that different origins may apply agreement tax rates. After a metal casting machine is classified under 847981, what is the export tax rebate rate? The export tax rebate rate is periodically adjusted by the State Taxation Administration; the latest export tax rebate rate database should be checked. Generally, mechanical and electrical products have higher rebate rates, but the specific rate is subject to official publication. It is recommended to consult the local tax authority or customs broker. If the metal casting machine is second-hand equipment, what should be noted during declaration? Second-hand equipment requires a condition statement, years of use, residual value, etc. Customs may require inspection and quarantine. When declaring, indicate 'second-hand' after the product name and truthfully fill in power, model, etc. Avoid penalties caused by inaccurate declaration. How should one choose between 847981 and 847989 for classification? 847981 is the specific subheading for metal casting machines; if the equipment meets the definition of a metal casting machine, it should be classified under 847981 first. 847989 is for other machines not elsewhere specified and is only used when the equipment does not belong to any specific subheading. Therefore, clarifying the equipment function is key.
