Chapter 84 covers nuclear reactors, boilers, machinery, mechanical appliances and their parts, and is one of the broadest chapters in the HS classification, covering power machinery, pumps, fans, machine tools, office equipment, automatic data processing equipment, etc. This chapter emphasizes the processing and working functions of mechanical appliances rather than mere material properties. Heading 8465 belongs to the machine tool category, specifically machine tools for working wood, cork, bone, hard rubber, hard plastics or similar hard materials, and is distinguished from metalworking machine tools (8456-8462) and cold-working machine tools for stone, ceramics, etc. (8464). Heading 8465 covers machine tools for working wood, cork, bone, hard rubber, hard plastics or similar hard materials by cutting, grinding, planing, milling, sawing, drilling, punching, mortising, profiling, turning, etc. This heading includes various types of woodworking machine tools, such as sawing machines, planing machines, milling machines, grinding machines, sanding machines, mortising machines, etc., whether or not numerically controlled. However, note that 8465 does not include hand-held pneumatic or electric tools (classified under 8467) or grinding machines for working metal (classified under 8460). First 2 digits 84: indicates Chapter 84, covering machinery, mechanical appliances and their parts. Digits 3-4, 65: indicates heading 8465, i.e., machine tools for working wood, cork, bone, hard rubber, hard plastics or similar hard materials. Digits 5-6, 93: indicates subheading 8465.93, specifically grinding machines, sanding machines or polishing machines. This subheading may be further subdivided (such as 8465.93.10, etc.), but this code is the 6-digit internationally standardized code. Overall meaning: CNC woodworking grinding machine, i.e., a machine tool that uses CNC technology to grind, sand or polish wood and other materials. This product is a CNC woodworking grinding machine, whose function is grinding and processing wood, conforming to the description of heading 8465 as "machine tools for working wood," and grinding machines are explicitly listed in subheading 8465.93. It does not belong to 8460 (metal grinding machines) because the material being worked is not metal; it also does not belong to 8467 (hand-held tools) because it is a stationary machine tool; and it certainly does not belong to 8479 (other machinery not elsewhere specified) because 8465 specifically names it. Therefore, classification under 8465.93 is the most accurate.

Product Name: Fill in the standard name of the goods, which should be consistent with the actual goods. It is recommended to use "CNC Woodworking Grinding Machine" or a specific model name. Use: Explain the processing object and scenario, such as "used for surface grinding and polishing of wood, for furniture manufacturing." Material Being Worked: Specify the processing object, such as "wood, engineered wood, cork," etc. Working Principle: Briefly describe the grinding method, such as "belt grinding, wheel grinding, CNC-controlled feed." Brand: Fill in the manufacturer or brand name; if no brand, write "no brand." Model: Fill in the specific model, such as "CNC-2000." Power: Fill in the main motor power, such as "7.5kW." CNC Unit Type: Specify the CNC system brand or number of controlled axes, such as "FANUC system, 3-axis simultaneous control." Product Name: CNC Woodworking Grinding Machine; Use: For surface grinding and polishing of solid wood furniture; Material Being Worked: Wood; Working Principle: Belt grinding, CNC-controlled feed; Brand: XXX; Model: CNC-2000; Power: 7.5kW; CNC Unit Type: FANUC system, 3-axis simultaneous control; Origin: China. Failure to indicate "CNC" may result in classification under a non-CNC grinding machine subheading. Vague filling of the material being worked, such as "hard materials," easily leads to misclassification under 8464. Misreporting a "sanding machine" as a "polishing machine," which, although under the same subheading, affects statistics.

Core basis for classification: First, determine whether the processing object is wood, cork, bone, hard rubber, hard plastics or similar hard materials; if so, consider 8465. Second, determine whether the processing method is grinding, sanding or polishing; if so, classify under 8465.93. Finally, confirm whether it is CNC; CNC and non-CNC may be further subdivided under the 6-digit subheading. If the processing object is metal, classify under 8460; if it is stone, ceramics, etc., classify under 8464; if it is a hand-held tool, classify under 8467. 8460.90 Other metal grinding machines: 8460 is for metalworking grinding machines; 8465 is for grinding machines for working wood and other non-metallic hard materials. The processing object is the core difference. 8464.20 Stone, ceramic grinding machines: 8464 is for working stone, ceramics, concrete and other mineral materials; 8465 is for working wood, cork and other organic hard materials. 8467.29 Hand-held electric grinding tools: 8467 is for hand-held pneumatic or electric tools; 8465 is for stationary machine tools. Whether it is hand-held is the key distinction. 8479.89 Other machinery not elsewhere specified: 8479 is a residual heading; if 8465 specifically names it, classification under 8465 takes precedence. 8465.91 Woodworking sawing machines: 8465.91 is for sawing machines; 8465.93 is for grinding machines. The processing method is different. Is the processing object wood or other non-metallic hard materials? Is the processing method grinding, sanding or polishing? Is it a stationary machine tool rather than a hand-held tool? Is it equipped with a CNC unit? Is it confused with headings 8460, 8464, 8467, etc.?

Which HS code should be looked up for a CNC woodworking grinding machine? Look up 8465.93. First determine Chapter 84, then find heading 8465 (machine tools for working wood, etc.), and then determine based on subheading 8465.93 (grinding machines, sanding machines or polishing machines). If it is CNC, it may be further subdivided under this subheading, but the 6-digit international code is 846593. Is there a difference in classification between a CNC woodworking grinding machine and an ordinary woodworking grinding machine? At the 6-digit HS code level, both are classified under 8465.93, because subheading 8465.93 does not distinguish whether it is CNC. However, in the 8-digit or 10-digit codes of some countries, CNC and non-CNC may be distinguished, and the customs tariff of the importing country should be consulted. If a woodworking grinding machine is also used for sanding plastics, can it still be classified under 8465? Yes, but it must be confirmed whether the plastic is hard plastic. 8465 covers the working of hard rubber, hard plastics or similar hard materials. If it is soft plastic, it may be classified under another heading. It is recommended to provide proof of material hardness. How should the "Working Principle" be filled in among the declaration elements for a CNC woodworking grinding machine? Briefly describe the grinding method, such as "belt grinding, with workpiece feed controlled by a CNC system, achieving curved surface grinding." Avoid writing only "grinding"; the CNC characteristics must be reflected. Does 8465.93 include polishing machines? Yes, subheading 8465.93 explicitly includes grinding machines, sanding machines or polishing machines. Polishing machines have functions similar to grinding machines and are both classified under this subheading. However, note that if a polishing machine is used for metal, it is classified under 8460. How can the import tariff rate for a CNC woodworking grinding machine be looked up? The tariff rate must be looked up according to the customs tariff of the importing country. It is recommended to use the importing country's official tariff database, enter HS code 846593, and check the most-favored-nation rate, preferential rates, etc. Also note whether anti-dumping or countervailing duties are involved. If a CNC woodworking grinding machine has a sawing function, how should it be classified? If grinding is the main function and sawing is an auxiliary function, it is still classified under 8465.93; if sawing is the main function, it may be classified under 8465.91 (sawing machines). Multi-function machine tools should be classified according to their main function, and a functional description is recommended. What should be noted for export declaration of a CNC woodworking grinding machine? It is necessary to accurately declare the product name, model, CNC unit, power and other elements, and provide a packing list, invoice and contract. If an export license or certificate of origin is involved, it must be handled in advance. It is recommended to confirm regulatory conditions with the customs broker.
