Chapter 84 is the major category of "nuclear reactors, boilers, machinery and mechanical appliances and parts thereof" in the HS classification system, covering power machinery, metalworking machine tools, industrial robots, office equipment, air-conditioning and refrigeration equipment, etc. This chapter emphasizes the power drive and mechanical functions of machinery and equipment, and is the core chapter for the classification of mechanical and electrical products in international trade. Heading 8462 covers "machine tools (including presses) for forging, die forging, stamping, rolling, drawing, extruding, roll forming, etc. of metal, and hammer forging machines." This heading focuses on machine tools that cause plastic deformation of metal by pressure or impact, excluding metal-cutting machine tools (8456-8461) and metal rolling mills (8455). The first 2 digits 84 = machinery and mechanical appliances; digits 3-4 62 = forging or stamping machine tools (including presses) and hammer forging machines; digits 5-6 10 = numerically controlled forging machines. "Numerically controlled" means the machining process is controlled by a digital program, as distinct from non-numerically controlled (846219) and other forging machines (846219). This subheading includes only numerically controlled forging machines and does not include numerically controlled stamping machines (846210? Note: 846210 is numerically controlled forging machines, while 846210 in some versions may cover numerically controlled stamping, but according to WCO notes, 8462.10 is forging or stamping machine tools (including presses) and hammer forging machines, numerically controlled. This code 846210 specifically refers to numerically controlled forging machines, i.e., numerically controlled equipment used for metal forging. This commodity is a numerically controlled forging machine, which uses numerical control to achieve plastic forming of metal blanks, conforms to the description of heading 8462 "forging machine tools," and has numerically controlled characteristics, so it is classified under subheading 846210. If it is a numerically controlled stamping machine, although it also belongs to 8462, the subheading may differ (such as 846210? Actually 846210 is forging or stamping machine tools, numerically controlled, but further subdivision depends on the specific function). Adjacent to 8462.10, 8462.21 is numerically controlled plate bending machines, etc., and the difference lies in the processing method.

Product name: The specific name of the declared commodity, such as "numerically controlled forging machine" or "numerically controlled die forging machine," which must be consistent with the contract and invoice. Brand type: Fill in foreign brand (OEM production), domestic brand, or no brand, which affects customs statistics and valuation. Model: Specific model specifications, such as "D53-2000," used to confirm equipment parameters and classification. Control method: Clearly state whether it is numerically controlled (CNC), and indicate the control system brand and number of axes. Processing method: Explain whether it is forging, die forging, or stamping, and whether hammer forging is included. Maximum forging pressure: In kilonewtons (kN) or tons, indicate the nominal pressure, which is key to determining equipment capability. Use: Specific processing object, such as "used for forging automotive connecting rods," avoiding vague expressions such as "general purpose." Power: Main motor power (kW), which affects energy consumption and valuation, and must be consistent with technical parameters. Customs declaration example: Product name: Numerically controlled forging machine Brand type: Foreign brand (Germany) Model: D53-2000 Control method: Numerically controlled, Siemens 840D, 5-axis Processing method: Die forging Maximum forging pressure: 20000 kN Use: Used for precision forging of automotive engine connecting rods Power: 75 kW Remarks: Imported as a complete machine, including control system. Failure to indicate "numerically controlled" leads to classification under 846219 (non-numerically controlled forging machine), and the tax rate and regulatory conditions may differ. Confusing "stamping" with "forging." Although 846210 covers stamping, if it is numerically controlled stamping, it is necessary to confirm whether the subheading is the same. Incorrect declaration of brand type, such as declaring OEM production as no brand, may trigger customs questioning.

Core basis for classification: 1) The commodity function is metal forging or stamping, belonging to heading 8462; 2) It has numerically controlled (CNC) characteristics, i.e., controlled by a digital program; 3) It is not a metal-cutting machine tool (8456-8461) or a metal rolling mill (8455). Reference should be made to the Explanatory Notes to heading 8462 and the national subheading notes on the definition of "numerically controlled." 846219 Non-numerically controlled forging machines: Non-numerically controlled forging machines are 846219, and the difference from 846210 lies in whether a numerical control system is equipped. A numerical control system must be capable of multi-axis linkage or program control. 846221 Numerically controlled bending, folding or straightening machine tools: 846221 is used for plate bending and folding, while 846210 is used for forging or stamping, with different processing methods. 846291 Numerically controlled hydraulic presses: 846291 is a hydraulic press, but if used for forging and numerically controlled, it should be classified under 846210; if used for stamping but not forging, it may be classified under 846291, depending on the processing object. 846299 Other numerically controlled machine tools: 846299 is for other numerically controlled machine tools not elsewhere specified, while 846210 specifically refers to forging or stamping machine tools, with a more specific function. 8462.10 Forging or stamping machine tools (including presses) and hammer forging machines, numerically controlled: 8462.10 itself is this code, but note that subheading subdivisions in some countries may differ, such as the U.S. HTSUS subdividing 8462.10 into multiple statistical codes. Is "numerically controlled" and the control system brand clearly indicated? Is the processing method forging or stamping? Have metal cutting and rolling functions been excluded? Are the maximum forging pressure and power consistent with the actual item? Is the brand type accurately declared?

What is the difference in HS codes between numerically controlled forging machines and numerically controlled stamping machines? Both may be classified under 8462, but the subheadings differ. 846210 is for numerically controlled forging machines (including die forging), while numerically controlled stamping machines, if for plate stamping, may be classified under 8462.21 or 8462.29, depending on the processing method and equipment structure. It is recommended to judge based on actual function and refer to the tariff notes. How can it be determined whether a forging machine is "numerically controlled"? Numerical control means the machining process is controlled by a digital program, usually with a CNC control system capable of multi-axis linkage and parameter programming. If it is only equipped with a digital display device or manual control, it is not numerically controlled and should be classified under 846219. For imported used numerically controlled forging machines, is the HS code the same? The HS code is the same, but used mechanical and electrical products must comply with customs regulatory conditions, which may involve pre-shipment inspection, licenses, etc. When declaring, it is necessary to indicate "used" and the years of use; the code remains 846210. In the declaration elements for numerically controlled forging machines, how should "processing method" be filled in? It should specifically state "forging" or "die forging." If it also has a stamping function, the main function should be indicated. Avoid vague expressions such as "metal forming" to prevent classification disputes. What is the export tax rebate rate for 846210? The export tax rebate rate changes with national policy adjustments and is not fixed. It is recommended to query the latest rebate rate by commodity code through the "China Customs Enterprise Import and Export Credit Information Publicity Platform" or the "Export Tax Rebate Query System." If a numerically controlled forging machine is equipped with a robotic loading and unloading device, does the classification change? If the robot is imported together with the main machine as an accessory device, it is usually classified according to the main machine, i.e., 846210. However, if the robot is packaged separately and has an independent function, it may need to be classified separately. It is recommended to provide an overall function description. What regulatory documents are required for importing numerically controlled forging machines? This may involve an automatic import license (O certificate), pre-shipment inspection certificate for used mechanical and electrical products, etc. The specifics depend on whether the equipment is new or used, the country of origin, and the trade mode. It is recommended to consult customs or a customs broker in advance. How can the most-favored-nation tax rate for 846210 be queried? You can log on to the website of the General Administration of Customs of China, enter the "Import and Export Tariff Query" system, enter code 846210, and check the most-favored-nation tax rate, general tax rate, and value-added tax rate. Note that tax rates may be adjusted annually, and the latest announcement shall prevail.
