Chapter 84 is one of the broadest chapters in the HS classification, covering various machines, mechanical appliances, machine parts, and equipment. Its core feature involves energy conversion, motion transmission, or material processing, including power machinery, agricultural machinery, metalworking machine tools, office equipment, automatic data processing equipment, transmission devices, etc. This chapter does not include electrical machinery (Chapter 85), optical instruments (Chapter 90), or vehicles (Chapter 87). For machine parts, if they are dedicated parts of a machine of a heading in this chapter, they are classified under that heading rather than under the general parts heading. Heading 8475 covers machines specialized for manufacturing bulbs, electronic tubes, television picture tubes, cathode ray tubes, and similar electric light sources, as well as machines for manufacturing glass or glassware (such as blowing, drawing, and forming equipment). Its scope includes: bulb sealing machines, exhausting machines, filament assembly machines, glass tube forming machines, glass bulb manufacturing machines, etc. However, this heading does not include: molds for glass manufacturing (classified under 8480), general machinery (such as pumps, fans), or the bulbs themselves (classified under 8539). Parts dedicated to the above machines are also classified under this heading. The first 2 digits, 84, indicate Chapter 84, covering machines, mechanical appliances, and their parts. The 3rd-4th digits, 75, indicate heading 8475, specifically machines for manufacturing bulbs, electronic tubes, television picture tubes, cathode ray tubes, and similar electric light sources, as well as machines for manufacturing glass or glassware. The 5th-6th digits, 90, indicate subheading 847590, i.e., parts of the above machines. Therefore, the complete meaning of 847590 is: parts dedicated to machines for manufacturing bulbs, electronic tubes, television picture tubes, and other electric light sources or glass manufacturing machines. Note: if the part is a general part (such as bolts, springs), it should not be classified under this code but under the corresponding heading according to its material (e.g., iron or steel bolts under 7318). The goods are parts of a bulb manufacturing machine. Since the bulb manufacturing machine is classified under heading 8475, its dedicated parts, according to HS General Rules of Interpretation 1 and 6, should be classified under subheading 847590 of the same heading. If the part is a general part (such as bearings, gears), it may be classified under 8483, etc.; if it is an electrical part (such as a sensor), it may be classified under Chapter 85. Therefore, the core determination is: whether the part is dedicated to the machines listed in 8475 and does not constitute goods more specifically covered by other headings.

Product Name: Fill in the Chinese and English names of the part, which should be specific and clear, such as "bulb sealing machine gripper". Avoid writing "machine part" in general terms. Use: Explain the machine to which the part is dedicated, such as "used for filament assembly of a bulb manufacturing machine (HS 8475)". It must correspond to the host machine. Material: Fill in the main material of the part, such as stainless steel, aluminum alloy, ceramics, glass, etc. Material affects classification, but dedication takes priority. Brand: Fill in the brand name (if no brand, write "no brand"), which helps customs identify the goods. Model: Fill in the part model or drawing number to facilitate matching with the host machine. If no model, write "no model". Applicable Host Machine Model: Fill in the model of the bulb manufacturing machine to which the part is adapted, strengthening the proof of dedication. Working Principle: Briefly explain the function of the part in the host machine, such as "used for clamping bulb glass shells". Is It a General Part: Declare whether the part is a general part (such as bolts, springs). If it is dedicated, fill in "No". Customs declaration example: Product Name: Bulb sealing machine gripper Use: Dedicated to bulb sealing machine (HS 8475) for clamping glass shells Material: Stainless steel Brand: No brand Model: FG-2024 Applicable Host Machine Model: LB-500 Working Principle: Pneumatically driven to clamp bulb glass shells for sealing Is It a General Part: No This part is a dedicated part of a bulb manufacturing machine and complies with HS 847590 classification. Mistakenly classifying general parts (such as bolts) under 847590; they should be classified under 7318, etc., according to material. Failure to provide host machine information, making it impossible for customs to determine dedication, possibly leading to classification under a general parts heading. Classifying electrical parts (such as sensors) under 847590; they should actually be classified under Chapter 85.

The core determination basis for classification is: whether the part is dedicated to the machines listed in heading 8475 (bulb manufacturing machines, etc.) and does not constitute goods more specifically covered by other headings. According to HS General Rules of Interpretation 1 and 6, dedicated parts should be classified under the same heading as the host machine. If the part is a general part (such as bearings, gears, bolts), it is classified under the corresponding heading according to material (such as 8483, 7318). If the part is an electrical part (such as a motor, sensor), it is classified under Chapter 85. Therefore, the dedication, function, and material of the part need to be examined. 848590 Parts of other machines: 848590 covers parts of machines of other headings, while 847590 only covers parts of machines of heading 8475. If the part is dedicated to a bulb manufacturing machine, it should be classified under 847590. 853990 Parts of electric light sources: 853990 is for parts of bulbs, tubes, and other electric light sources, while 847590 is for parts of machines that manufacture these electric light sources. The former is product parts, the latter is production equipment parts. 848310 Transmission shafts and cranks: If the part is a general transmission shaft, it should be classified under 848310; if it is a transmission shaft dedicated to a bulb manufacturing machine, it is classified under 847590. 847990 Parts of other dedicated machines: 847990 is for parts of machines of heading 8479, while 847590 is for parts of machines of heading 8475. They should be distinguished based on the host machine heading. 701190 Glass bulb parts: 701190 is for glass bulb shells, etc., which are glass products; while 847590 is for parts of machines that manufacture bulbs, regardless of material. Is the part dedicated to the machines listed in 8475? Is the part a general part (such as bolts, gears)? Does the part have an electrical function (such as a motor, sensor)? Is the host machine classified under 8475? Have more specific classifications under other headings been ruled out?

How to determine whether a part is dedicated to a bulb manufacturing machine? It is mainly based on its design, structure, and use. If the part can only be used in a bulb manufacturing machine and cannot be used in other machines, it is considered dedicated. For example, a specially shaped gripper is only suitable for a bulb sealing machine. If the part is a general part (such as a standard bolt), it is not dedicated. How should parts of a bulb manufacturing machine be classified if they are also electrical parts? If the part has an independent electrical function (such as a motor, sensor) and is among the goods listed in Chapter 85, it should be classified under Chapter 85. For example, a motor used in a bulb manufacturing machine should be classified under 8501. However, if it is only a mechanical structural part, even if used in electrical equipment, it is still classified under 847590. What is the difference between 847590 and 848590? 847590 specifically refers to parts of machines of heading 8475, i.e., parts of equipment such as bulb manufacturing machines; 848590 is for parts of machines of other headings (such as 8479). The host machines are different, and the host machine heading must be determined first for classification. When importing parts of a bulb manufacturing machine, is it mandatory to provide the host machine model in the declaration elements? It is recommended to provide it. The host machine model helps customs confirm the dedication of the part and avoid misclassification as a general part. If it cannot be provided, the use should be described in detail as dedicated to a bulb manufacturing machine, with technical documents attached. If a part of a bulb manufacturing machine is made of glass, should it be classified under 847590 or 701190? If the glass part is part of the machine (such as a glass guide rail) and is dedicated to a bulb manufacturing machine, it is classified under 847590. If it is a product part such as a glass bulb shell, it is classified under 701190. The key is whether it is a machine part or a product part. What is the export tax rebate rate for 847590? The export tax rebate rate is adjusted with national policies and is not fixed. It is recommended to check the latest rebate rate through the official website of the General Administration of Customs or the State Taxation Administration, or use professional tariff query tools. Generally, the rebate rate for mechanical and electrical products is relatively high, but the actual rate shall prevail. How to query the MFN tariff rate for 847590? You can log in to the website of the General Administration of Customs of China, enter "Import and Export Tariff" to query, or use the "China Customs Import and Export Tariff" APP. You can also entrust a customs broker to query. Tariff rates may be adjusted annually, and the latest version shall prevail. Can old parts of bulb manufacturing machines be imported? The import of used mechanical and electrical products must comply with national regulations, and some old parts are prohibited from import. It is recommended to first check the "Catalogue of Prohibited Imports of Used Mechanical and Electrical Products" and handle relevant inspection and quarantine procedures. If import is allowed, classification is still declared under 847590.
