Chapter 84 is the core chapter in the HS classification covering mechanical machinery and their parts, including power machinery, metalworking machine tools, industrial robots, office equipment, etc. This chapter emphasizes the function and working principle of machines, rather than materials or uses. The chapter notes explicitly exclude certain specific equipment (such as hand-held tools, textile machinery, etc.) and stipulate the principles for classifying parts. For metalworking machinery, the key to distinguishing Chapter 84 from Chapter 85 (electrical equipment) lies in whether mechanical function is predominant. Heading 8463 covers other metalworking machine tools (including wire drawing machines, thread rolling machines, wire processing machines, etc.), but excludes cutting machine tools (8456-8461) and forging and stamping machine tools (8462). This heading specifically refers to machine tools that form, process, or finish metal wire, tube, or profiles by non-cutting methods, such as wire drawing, extrusion, thread rolling, bending, straightening, etc. Under 8463, they are further subdivided by workpiece and process. First 2 digits 84: belongs to Chapter 84, representing mechanical machinery and parts. Digits 3-4, 63: heading 8463, representing other metalworking machine tools (non-cutting type). Digits 5-6, 30: subheading 846330, specifically referring to numerically controlled metal wire processing machines. Here, "numerically controlled" means controlled by a digital program, and "metal wire processing" means drawing, straightening, cutting, bending, forming, etc., of metal wire. This subheading is the dedicated classification under 8463 for wire processing equipment. This commodity is a numerically controlled metal wire processing machine, whose core function is to perform non-cutting processing (such as wire drawing, straightening, bending, forming) on metal wire under the control of a numerical control system. It is not a cutting machine tool of 8456-8461, nor a forging or stamping machine tool of 8462. Heading 8463 explicitly covers wire processing machine tools, and subheading 846330 is specifically for numerically controlled models, so classification under this code is the most accurate.

Product name: The specific name of the declared commodity should include key information such as "numerically controlled" and "metal wire processing machine", and avoid generally writing "machine". Use: Explain what kind of metal wire the machine is used to process, such as steel wire, copper wire, aluminum wire, etc., as well as the final product type. Working principle: Briefly describe the processing method, such as drawing, straightening, bending, cutting, forming, etc., and explain how the numerical control system controls it. Brand: Fill in the machine brand (such as Siemens, Bühler, etc.); if there is no brand, write "no brand". Model: Fill in the specific model, which should be consistent with the machine nameplate, to distinguish different specifications. Processing wire diameter range: In millimeters, indicate the minimum and maximum diameters that can be processed, reflecting the machine's capability. CNC system brand and model: Fill in the brand and model of the numerical control system, such as FANUC 0i-TF, to prove its numerically controlled attribute. Power: Fill in the total power of the machine (kW), including the main motor and numerical control system, etc. Product name: numerically controlled metal wire processing machine; Use: used to process copper wire with a diameter of 0.5-3mm to produce electronic connecting wires; Working principle: the numerical control system controls servo motors to achieve straightening, cutting, and bending forming of wire; Brand: Bühler; Model: WPM-300; Processing wire diameter range: 0.5-3mm; CNC system brand and model: Siemens 828D; Power: 15kW. Failure to indicate "numerically controlled", which may lead to incorrect classification under other subheadings of 8463. The use description is too general and does not specify the specific material and diameter of the processed wire. The working principle does not reflect the control of the processing by the numerical control system, making it easy to question whether it is numerically controlled.

The core basis for classification is: 1) whether the machine is used for processing metal wire; 2) whether the processing method is non-cutting (such as drawing, straightening, bending, etc.); 3) whether it is equipped with a numerical control system to achieve digital program control. Also refer to the chapter notes to Chapter 84 and the text of heading 8463. If the machine also has cutting functions, it must be judged according to the principal function. 8462 Metal forging and stamping machine tools: 8462 covers machine tools that process metal by forging, stamping, bending, etc., but usually for sheets and profiles rather than wire; and 8462 does not emphasize numerically controlled wire processing. 8461 Metal cutting machine tools: 8461 covers machine tools that remove material by cutting, such as lathes and milling machines; while the machines of 846330 do not cut, but perform forming processing. 8479 Other machines with individual functions: 8479 is a residual heading; if a machine does not meet the specific description of 8463, it may be classified under 8479; however, numerically controlled wire processing machines are explicitly listed in 846330, so classification there takes priority. 8515 Welding machines: 8515 covers welding equipment. If a wire processing machine has an attached welding function, it must be judged according to the principal function; pure wire processing is not classified under 8515. Is the machine specifically used for metal wire processing? Is the processing method non-cutting (drawing, straightening, bending, etc.)? Is it equipped with a numerical control system to achieve digital program control? Does it not belong to the forging and stamping machine tools of 8462 or the cutting machine tools of 8461? Has it not been combined with machines of other functions in a way that changes the principal function?

How can one determine whether a metal wire processing machine is numerically controlled? Numerical control means controlling the processing through a digital program, usually equipped with a numerical control system (such as FANUC, Siemens, etc.), which can programmatically control servo motors to achieve multi-axis linkage. If it is adjusted only by mechanical cams or manually, it is not numerically controlled. When declaring, the brand and model of the numerical control system must be provided. What is the difference in classification between a numerically controlled metal wire processing machine and an ordinary wire processing machine? If an ordinary wire processing machine is non-numerically controlled, it may be classified under other subheadings of 8463 (such as 846390); while numerically controlled models are specifically classified under 846330. Therefore, whether it is numerically controlled is the key distinction. If a machine can process both wire and tube, how should it be classified? According to the General Rules for the Interpretation of the Harmonized System, it should be classified according to its principal function. If the principal function is wire processing, it is classified under 846330; if the principal function is tube processing, it may be classified under other subheadings of 8463 or 8462. Evidence such as processing proportions and designed use must be provided. When declaring, is the processing wire diameter range mandatory? Yes, this is an important declaration element used to prove the machine's processing capability and applicability. It is recommended to provide a specific numerical range and avoid vague descriptions. How are parts of numerically controlled metal wire processing machines classified? According to the chapter notes to Chapter 84, the classification of parts depends on whether they are dedicated to that machine. If they are dedicated to machines of 846330, they are classified under the parts subheading of 8463 (such as 846390); if they are general-purpose parts, they are classified according to material. If a small numerically controlled wire processing machine is purchased from a cross-border e-commerce platform for personal use, how should it be declared? Items for personal use also need to be declared according to the HS code, but may be subject to personal postal articles tax. It is recommended to provide purchase receipts, machine specifications, etc., and declare according to customs requirements. If the quantity is reasonable, it can be classified under 846330. How can one inquire about the tariff rate for 846330? Tariff rates vary by country and trade agreement, and may change. The latest rates can be obtained through customs official websites, tariff query platforms, or by consulting a customs broker. Note the differences between most-favored-nation rates, general rates, and free trade agreement rates. Does a numerically controlled metal wire processing machine require an export license when exported? It depends on the exporting country's control list. Generally, numerically controlled machine tools may involve export controls, especially high-precision models. It is recommended to check the export control regulations of the home country and apply for a license if necessary.
