Chapter 84 covers nuclear reactors, boilers, machinery, mechanical appliances and parts thereof, and is the largest industrial product category chapter in the HS classification. This chapter includes power machinery, agricultural machinery, machine tools, office equipment, automatic data processing equipment, semiconductor and flat panel display manufacturing equipment, etc. The core characteristic is that these goods usually have power-driven, mechanical motion or electronic control functions, and are used for production, processing or energy conversion. Heading 8486 is one of the most technology-intensive areas in this chapter, specifically referring to equipment for processing materials by a change in temperature and equipment for manufacturing semiconductor devices and flat panel displays. Heading 8486 covers machines and apparatus specially designed for or mainly used in the manufacture of semiconductor devices, integrated circuits, flat panel displays, LEDs, solar cells and other electronic components. This heading includes equipment for processing materials by a change in temperature (such as diffusion furnaces and oxidation furnaces), physical vapor deposition equipment, chemical vapor deposition equipment, etching equipment, ion implanters, lithography equipment, packaging equipment, and related auxiliary equipment not specified or included in other headings of this chapter. The core criterion for determination is the specificity of the equipment - it must be specially designed for the manufacture of the above-mentioned electronic components, rather than general-purpose industrial equipment. Code 848630 is a six-digit subheading. The first 2 digits "84" represent Chapter 84, i.e., nuclear reactors, boilers, machinery, mechanical appliances and parts thereof, indicating that the goods belong to the machinery category. The 3rd-4th digits "86" represent heading 8486, i.e., machines and apparatus specially designed for or mainly used in the manufacture of semiconductor devices, integrated circuits, flat panel displays, LEDs, solar cells, etc. This heading is one of the most technologically advanced headings in Chapter 84. The 5th-6th digits "30" represent subheading 848630, which is further subdivided under heading 8486 and specifically refers to flat panel display manufacturing equipment. Under heading 8486, there are also subheadings such as 848610 (semiconductor device manufacturing equipment), 848620 (integrated circuit manufacturing equipment), 848640 (LED manufacturing equipment), and 848650 (solar cell manufacturing equipment). Therefore, 848630 precisely identifies equipment specially used in the production process of flat panel displays (such as LCD, OLED, and plasma displays). The goods are classified under 848630 rather than adjacent codes, primarily because of their attribute of being "specially designed for flat panel display manufacturing." 848610 and 848620 target semiconductor devices and integrated circuits respectively, 848640 targets LEDs, and 848650 targets solar cells. Flat panel display manufacturing equipment (such as liquid crystal dropping and injection machines, OLED evaporation machines, and glass substrate transfer robots) has unique process requirements and is not applicable to the manufacture of other electronic components. If the equipment is of a general-purpose type (such as a general-purpose cleaning machine), it should be classified under other headings (such as 8479). Therefore, being specially designed for flat panel display manufacturing is the key to classification under 848630.

Product Name: The standard name of the declared goods, which should accurately reflect the equipment's function, such as "vacuum evaporation machine for flat panel display manufacturing." Use: Clearly state which process step of flat panel display manufacturing the equipment is used for, such as array, cell assembly, module, etc. Working Principle: Briefly describe how the equipment achieves its function, such as "depositing organic materials onto a substrate by vacuum evaporation." Brand: Fill in the equipment brand (such as Canon, Applied Materials). If there is no brand, fill in "no brand." Model: Fill in the equipment model or specification, such as "AKT-5500." Power: Fill in the rated power of the equipment (such as "10kW"), which helps determine the equipment type. Whether specially designed for flat panel display manufacturing: Clearly answer "yes" or "no." This is the key to classification under 848630. Product Name: Vacuum evaporation machine for flat panel display manufacturing; Use: For organic layer evaporation of OLED panels; Working Principle: Heating organic materials in a vacuum environment to sublime and deposit them on a glass substrate; Brand: Canon Tokki; Model: ELV-8; Power: 50kW; Whether specially designed for flat panel display manufacturing: Yes. Declaring general-purpose cleaning equipment as 848630, when it should actually be classified under 8479 or 8424. Failing to specify that the equipment is specially designed for flat panel displays, resulting in classification under 848610 or 848620. The working principle description is vague and cannot prove that the equipment is used for flat panel display manufacturing.

The core criterion for classification is the specificity of the equipment. According to the chapter notes to Chapter 84 and the text of heading 8486, only equipment specially designed for or mainly used in the manufacture of flat panel displays is classified under 848630. In determination, the following should be considered: 1) whether the equipment is used in a specific process of flat panel display production (such as liquid crystal dropping, OLED evaporation, substrate transfer, etc.); 2) whether the equipment cannot be used for manufacturing other products; 3) whether the equipment belongs to a type named in heading 8486 (such as equipment for processing materials by a change in temperature). If the equipment is of a general-purpose type, even if used in flat panel display manufacturing, it should be classified under other headings. 848610 Semiconductor device manufacturing equipment: 848610 targets the manufacture of semiconductor devices (such as diodes and transistors), while 848630 targets flat panel display manufacturing. The processes are different, and the equipment is not interchangeable. 848620 Integrated circuit manufacturing equipment: 848620 is specially used for integrated circuit manufacturing, such as lithography machines and etching machines. Although flat panel display manufacturing equipment is similar, it targets large-size glass substrates, so it is classified under 848630. 848640 LED manufacturing equipment: 848640 is used for LED chip manufacturing, such as MOCVD equipment. Flat panel display manufacturing equipment is used for LCD/OLED panels, and the processes and substrate sizes are different. 848650 Solar cell manufacturing equipment: 848650 is used for solar cell production, such as PECVD equipment. Flat panel display manufacturing equipment is used for display panels, and the substrate and process requirements are different. 8479 Machines not specified or included in other headings of this chapter: 8479 is a residual heading. If the equipment is not specially designed for flat panel display manufacturing, or cannot be classified under 8486, it may be classified under 8479. Is the equipment specially designed for flat panel display manufacturing? Does the equipment belong to a type named in heading 8486? Is the equipment used for semiconductor or integrated circuit manufacturing? Is the equipment general-purpose and usable in other industries? Does the equipment process materials by a change in temperature?

How can it be determined whether a piece of equipment belongs to 848630? First confirm whether the equipment is specially designed for flat panel display manufacturing, such as for a specific process in LCD or OLED panel production. Second, the equipment should belong to a type named in heading 8486, such as equipment for processing materials by a change in temperature, physical vapor deposition equipment, etc. If the equipment is of a general-purpose type, even if used in flat panel display manufacturing, it should be classified under other headings. What is the difference between 848630 and 848620? 848630 specifically refers to flat panel display manufacturing equipment, such as OLED evaporation machines and liquid crystal dropping and injection machines. 848620 specifically refers to integrated circuit manufacturing equipment, such as lithography machines and etching machines. Although both belong to 8486, they target different products, and the equipment is not interchangeable. Under which code should a cleaning machine used for flat panel display manufacturing be classified? If the cleaning machine is specially designed for flat panel display manufacturing and belongs to a type named in heading 8486 (such as equipment for processing materials by a change in temperature), it should be classified under 848630. If it is a general-purpose cleaning machine, it should be classified under 8479 or 8424. The determination should be based on the equipment's specific function and specificity. What key information is required when declaring 848630? Product name, use, working principle, brand, model, power, whether specially designed for flat panel display manufacturing, etc. are required. Among these, "whether specially designed for flat panel display manufacturing" is the key to classification and must be clearly answered. If equipment can be used for both flat panel display manufacturing and semiconductor manufacturing, how should it be classified? According to the General Rules for the Interpretation of the Harmonized System, if equipment has multiple uses, it should be classified according to its principal use. If the principal use cannot be determined, it may be classified under 8479. It is recommended to provide technical documentation for the equipment to prove its principal use. How can the tariff rate for 848630 be checked? Tariff rates vary by country, trade agreement, and annual adjustments. The latest rates can be obtained through the official website of the customs administration, HS code query platforms, or by consulting a customs broker. Note that rates may differ depending on the country of origin. What certifications are required to export flat panel display manufacturing equipment to the United States? This depends on the equipment type and may involve FDA, UL, CE and other certifications. In addition, it is necessary to confirm whether it is subject to export controls (such as EAR) and to prepare the corresponding customs declaration documents. It is recommended to consult a professional customs broker. What are the key points of customs inspection when importing equipment under 848630? Customs focuses on checking whether the equipment's specificity, working principle, and model are consistent with the declaration, and whether it falls within the scope of heading 8486. Technical manuals, photographs and other supporting documents may be required.
