Chapter 84 is the core chapter in the HS classification system for machinery and mechanical appliances and parts thereof, covering an extremely broad range, from power machinery, pumps, fans, and refrigeration equipment to various processing machines, office equipment, and automatic data processing equipment. The basic characteristic of this chapter is that goods must be driven by mechanical power or independently perform some physical processing function, and usually do not involve the core of electrical control (classified under Chapter 85). As equipment that uses mechanical pressure to press wood particles, fibers, or veneers into shape, the wood pressing machine has a core function belonging to the category of mechanical processing, and is therefore classified under this chapter. Heading 8479 is a residual heading in Chapter 84, with the full title "Machines and mechanical appliances having individual functions, not specified or included elsewhere in this chapter." This heading covers a very broad range, including but not limited to: public works machinery, wood treatment machinery, pulp-making machinery, cable-making machinery, etc. Because the wood pressing machine is not specified in a more specific heading (such as 8465 woodworking machine tools) and its function is to form wood particles through pressure, it meets the definition of a "machine having an individual function" and is therefore classified under 8479. Code 847930 is a six-digit subheading, broken down digit by digit: the first 2 digits "84" represent Chapter 84, namely nuclear reactors, boilers, machinery, mechanical appliances, and parts thereof; the 3rd-4th digits "79" represent heading 8479, namely machines and mechanical appliances having individual functions, not specified or included elsewhere in this chapter; the 5th-6th digits "30" represent subheading 847930, specifically referring to wood pressing machines. In the HS classification, this subheading is further refined as "presses for the manufacture of particle board or fibre board of wood or other ligneous materials, and other machinery for treating wood or cork," but according to the Chinese name "木材压制机" and the English "Wood pressing machine," its core reference is to pressing equipment in the field of wood processing. This commodity is classified under 847930 rather than adjacent codes because: although heading 8465 covers woodworking machine tools, it mainly refers to machine tools that process wood by cutting, sawing, planing, etc., whereas a pressing machine forms wood particles through pressure, which is non-cutting processing; heading 8479, as a residual heading, explicitly includes "wood treatment machinery," and subheading 847930 specifically lists wood pressing machines. Therefore, according to General Rules 1 and 6 for the interpretation of the HS, this commodity should be classified under 847930.

Product name: The Chinese and English names of the declared commodity should accurately reflect the equipment's function, such as "木材压制机" or "Wood pressing machine." Use: Explain the specific application scenario of the equipment, such as being used to press wood particles, fibers, or veneers into boards, profiles, etc. Working principle: Briefly describe the pressing method, such as hot pressing, cold pressing, continuous pressing, or intermittent pressing, as well as the pressure source (hydraulic, pneumatic, mechanical). Brand: Fill in the equipment brand (if there is no brand, fill in "no brand"); brand does not affect classification but is a required declaration item. Model: Fill in the equipment model or specifications, such as pressure tonnage, platen size, etc., to distinguish different equipment. Power: Fill in the main motor power of the equipment (kW), reflecting the equipment's energy consumption and scale. Processing object: Clarify the material form before pressing, such as wood chips, wood fibers, veneers, shavings, etc. Whether numerically controlled: Explain whether the equipment is equipped with a numerical control system, which affects classification and regulatory conditions. Example of customs declaration elements: Product name: Wood pressing machine (木材压制机) Use: Used to hot-press a mixture of wood particles and adhesive into artificial boards Working principle: Hydraulically driven, hot-press forming, maximum pressure 2000 tons Brand: XX Model: XX-2000 Power: 75 kW Processing object: Wood shavings, wood fibers Whether numerically controlled: Not numerically controlled (Note: The above is a simulated entry; actual declaration must be adjusted according to the specific equipment conditions and customs requirements.) Incorrectly classifying wood pressing machines under 8465 (woodworking machine tools), ignoring their non-cutting processing characteristics. Failure to indicate "hot pressing" or "cold pressing" at declaration, which may affect subheading determination. Ignoring whether the equipment has an individual function; if it is a component of a production line, classification must be done cautiously.

The core basis for classification is General Rules 1 and 6 for the interpretation of the HS. First, the wood pressing machine belongs to Chapter 84 machinery and, because it is not specified in a more specific heading such as 8465, is classified under residual heading 8479. Second, subheading 847930 explicitly lists "wood pressing machines," so the six-digit subheading is directly locked in. Key determination points include: whether the equipment uses pressure as the main processing method, whether it is dedicated to wood, and whether it has an individual function. If the equipment is an auxiliary device in a wood processing production line, it is necessary to determine based on its main function whether it is still classified under 847930. 8465 Woodworking machine tools: 8465 covers machine tools that process wood by cutting, sawing, planing, etc., whereas the pressing machine under 847930 forms wood particles through pressure and does not involve cutting. 8477 Plastics processing machinery: 8477 is used for machinery for processing plastics or rubber. If a pressing machine can process both wood and plastics, classification must be determined according to its main use; if dedicated to wood, it is classified under 847930. 8480 Molding boxes and molds for metal casting: 8480 includes molds for metal casting, whereas a wood pressing machine is a machine for processing wood. If the mold itself is declared separately, it should be classified under 8480, but the complete machine is classified under 847930. 8479 Other machines having individual functions: 8479 is a residual heading. If a wood pressing machine does not meet the specific subheading 847930, it may be classified under another 8479 subheading, but 847930 already explicitly lists it. Does the equipment use pressure as the main processing method? Is the processing object wood or wood-based materials? Does it have an individual function rather than being an accessory device of a production line? Is it not specified in a more specific heading such as 8465? Is it dedicated to pressing rather than cutting or grinding?

The wood pressing machine is classified under 847930, but my equipment is a hot press. Is it still classified under this code? Yes. Subheading 847930 covers wood pressing machines, whether hot pressing or cold pressing, as long as pressure is used to form wood particles, it is classified under this code. However, at declaration, it is necessary to indicate hot pressing or cold pressing for customs review. How do you distinguish a wood pressing machine from a plastic pressing machine? Mainly by the processing object. If the equipment is dedicated to wood or wood-based materials, it is classified under 847930; if dedicated to plastics or rubber, it is classified under 8477. If it can be used universally, it must be determined according to its main use or design principle, and it is recommended to provide technical documentation. If a wood pressing machine is equipped with a numerical control system, will this affect classification? It will not affect six-digit subheading classification; it is still classified under 847930. However, numerically controlled equipment may involve export controls or regulatory conditions, and at declaration it is necessary to truthfully fill in "whether numerically controlled" and pay attention to relevant regulations. What declaration elements are required for importing a wood pressing machine? Product name, use, working principle, brand, model, power, processing object, whether numerically controlled, etc. are required. The specific requirements are subject to customs requirements; it is recommended to consult the "Customs Import and Export Commodity Specification Declaration Catalog of the People's Republic of China" in advance. How can the tax rate for wood pressing machines be checked? Tax rates may change. The latest tax rate can be checked through the official website of the General Administration of Customs, China International Trade Single Window, or the "Import and Export Tariff of the People's Republic of China." It is recommended to rely on the tariff in effect at the time of actual declaration. If the wood pressing machine is second-hand equipment, is the classification different? The classification remains unchanged; it is still classified under 847930. However, import of second-hand equipment may involve additional requirements such as pre-shipment inspection and licenses, and customs or professional institutions should be consulted in advance. What is the difference between a wood pressing machine and a woodworking thickness planer? A woodworking thickness planer belongs to 8465 and processes the wood surface by cutting; a wood pressing machine forms particles through pressure and does not involve cutting. The processing principles and objects are different, and the classifications are different. Can exporting wood pressing machines to ASEAN enjoy agreement tax rates? It is necessary to confirm whether the equipment is included in the ASEAN agreement tax rate list and meets the rules of origin. You can check the China-ASEAN Free Trade Agreement tariff schedule or consult the local customs.
