Chapter 84 is the chapter in the HS classification system covering nuclear reactors, boilers, machinery, mechanical appliances and their parts, and is one of the most core chapters for electromechanical products. This chapter includes power machinery, pumps, fans, machine tools, construction machinery, office equipment, automatic data processing equipment, etc., covering a very wide scope. Within the chapter, headings are divided by function or use, such as 8462 for metalworking machine tools and 8463 for other metalworking machine tools. Understanding this chapter requires grasping the distinction between 'machinery' and 'appliances', as well as the principles for classifying parts. Heading 8462 covers metalworking machine tools (including presses, bending machines, shearing machines, punching machines, forging machines, etc.) used for plastic deformation processing of metal, such as bending, folding, straightening, shearing, punching, stamping, etc. This heading includes both CNC machine tools and non-CNC machine tools; both hydraulic and mechanical types. However, 8462 does not include metal cutting machine tools (classified under 8456-8461) or metal rolling mills (classified under 8455). Code 846221 has 6 digits. The first 2 digits '84' represent Chapter 84, i.e., machinery, mechanical appliances and their parts. The 3rd-4th digits '62' represent heading 8462, i.e., metalworking machine tools (including presses, bending machines, shearing machines, etc.). The 5th-6th digits '21' represent subheading 846221, specifically CNC bending machines. In HS classification, the 5th digit indicates the subheading level, and the 6th digit indicates a more detailed statistical subheading. 846221 specifically refers to bending machines using a CNC system, distinguished from non-CNC bending machines (846229). This commodity is a CNC bending machine, belonging to metal sheet plastic deformation processing equipment, controlling bending angle and position through a CNC system, so it is classified under 8462. It is not classified under 8462.29 (non-CNC bending machines) because it has CNC functionality; not under 8456 (laser cutting machines) because the processing principle is bending rather than cutting; not under 8463 (other metalworking machine tools) because bending machines are already explicitly named under 8462.

Product Name: The Chinese and foreign language names of the declared commodity should accurately reflect the equipment type, such as 'CNC bending machine' or 'CNC bending machine'. Brand: Fill in the equipment brand, such as 'AMADA', 'TRUMPF', etc.; if no brand, fill in 'no brand'. Model: Fill in the specific model, such as 'HG-1003', 'PB-135', etc., used to distinguish specifications. Control Method: Indicate 'CNC' or 'non-CNC'; for CNC, further specify the control system brand and model. Metal Type Processed: Explain the processing object, such as 'steel plate', 'aluminum plate', 'stainless steel plate', etc. Maximum Bending Thickness: Fill in the maximum sheet thickness the equipment can bend, in millimeters. Maximum Bending Length: Fill in the maximum sheet width the equipment can bend, in millimeters. Power: Fill in the main motor power, in kilowatts, used to confirm equipment specifications. Product Name: CNC bending machine; Brand: AMADA; Model: HG-1003; Control Method: CNC, control system brand DELEM, model DA-66T; Metal Type Processed: steel plate; Maximum Bending Thickness: 6mm; Maximum Bending Length: 3000mm; Power: 11kW; Use: used for metal sheet bending and forming; Origin: Japan. Mistakenly reporting a non-CNC bending machine as CNC, leading to classification errors. Omitting the declaration of the control system brand and model, affecting customs valuation. Not indicating the metal type processed, which may raise doubts about classification. Model inconsistent with the actual item, triggering inspection risks.

The core basis for classification is the 'Import and Export Tariff' and the 'HS Explanatory Notes'. Heading 8462 explicitly includes 'metalworking machine tools (including presses, bending machines, shearing machines, punching machines, forging machines, etc.)'. CNC bending machines are classified under subheading 846221 because they have a CNC system. If the equipment is a bending machine but not CNC, it is classified under 846229. If the equipment has both bending and shearing functions, it should be classified according to the main function. If it is a laser cutting and bending integrated machine, it should be determined according to the main processing method. 846229 Non-CNC bending machines: This code refers to non-CNC bending machines, and the core difference from 846221 is whether a CNC system is equipped. A CNC system can automatically control the bending angle and position, while non-CNC requires manual adjustment. 846239 Other non-CNC metalworking machine tools: 846239 covers non-CNC shearing machines, punching machines, etc., while 846221 specifically refers to CNC bending machines. If the equipment is a CNC shearing machine, it should be classified under 846231. 845690 Other metalworking machine tools: 845690 includes electrochemical, laser, ultrasonic and other non-traditional metalworking machine tools, while 846221 is traditional mechanical bending. If it is laser bending, it should be classified according to laser processing. 846299 Other CNC metalworking machine tools: 846299 covers other CNC metalworking machine tools, such as CNC punching machines, CNC shearing machines, etc., while 846221 is limited to CNC bending machines. Is the equipment equipped with a CNC system? Is the processing object metal sheet? Is the main function bending? Does it have other processing functions? Is the model consistent with the declaration?

What is the difference in HS codes between CNC bending machines and ordinary bending machines? CNC bending machines are classified under 846221, and ordinary bending machines (non-CNC) are classified under 846229. The key difference is whether a CNC system is equipped. A CNC system can automatically control the bending angle and position, while non-CNC requires manual adjustment. When declaring, the control system brand and model must be provided. How to determine whether a bending machine is CNC? CNC bending machines are usually equipped with a CNC controller that can programmatically control the bending angle, back gauge position, ram stroke, etc. If only equipped with a digital display device or manual adjustment, it is not CNC. Customs may require the controller model and photos of the operation interface. What key elements need to be declared for CNC bending machines classified under 846221? Key elements include: product name, brand, model, control method (CNC), control system brand and model, metal type processed, maximum bending thickness, maximum bending length, power, etc. These elements help customs confirm classification, valuation, and statistics. If a bending machine also has a shearing function, how should it be classified? According to the 'HS Explanatory Notes', multi-function machine tools should be classified according to the main function. If the main function is bending, classify under 846221; if the main function is shearing, classify under 846231 (CNC shearing machines). If the main function cannot be determined, refer to the equipment design, use, and sales materials. For imported used CNC bending machines, is the HS code the same? Yes, the HS code does not change due to new or used condition and remains 846221. However, importing used equipment requires a pre-shipment inspection certificate and may involve prohibited or restricted import regulations. It is necessary to check the 'Catalog of Goods Prohibited from Import' and the 'Catalog for Import License Administration' in advance. How to inquire about the tariff rate for CNC bending machines? The tariff rate must be inquired based on the country of origin, trade agreements, and the latest tariff. It can be obtained through the official website of the General Administration of Customs of China, the International Trade Single Window, or by consulting a customs broker. Note that rates may change; it is recommended to refer to the tariff at the time of declaration. When exporting CNC bending machines to the EU, is the HS code consistent? The first 6 digits of the EU HS code are consistent with the international code, and 846221 is the same. However, the EU may have subdivisions in the 7th-8th digits, which need to be checked in the EU TARIC database. When exporting, documents such as a declaration of conformity and CE certification must be provided. When classifying CNC bending machines, which codes are easily confused? Easily confused with 846229 (non-CNC bending machines), 846239 (other non-CNC metalworking machine tools), 846299 (other CNC metalworking machine tools), and 845690 (other metalworking machine tools). The main differences lie in whether it is CNC, the processing method, and the function.
