Chapter 84 is the core chapter in the HS classification system covering mechanical appliances and parts, including power machinery, agricultural machinery, machine tools, office equipment, automatic data processing equipment, bearings, transmission devices, etc. Goods in this chapter usually have a mechanical function or serve as dedicated parts of machinery, but exclusion provisions must be noted, such as certain electrical equipment classified under Chapter 85. Heading 8467 covers hand-held pneumatic tools, hand-held power tools (including electromechanical) and non-electrical parts of these tools. Specifically includes: pneumatic hand-held tools (such as pneumatic wrenches, pneumatic grinders), electric hand-held tools (such as electric drills, electric saws, electric grinders) and their dedicated parts (such as drill chucks, saw blades, grinding wheels, etc.). First 2 digits 84 = machinery, mechanical appliances, electrical equipment and parts thereof; digits 3-4: 67 = hand-held pneumatic or power tools; digits 5-6: 99 = other tool parts, i.e., subheading 8467.99, specifically for classifying parts of hand-held pneumatic or power tools, but excluding electrical parts (such as motors, switches) and certain specific parts (such as drill bits, saw blades, etc. that are separately named). The goods are dedicated parts of hand-held pneumatic or power tools, and are not specifically named in other subheadings (such as drill bits under 8207, saw blades under 8202), nor are they electrical parts (under Chapter 85), therefore classified under 8467.99. If the parts are general-purpose parts (such as bolts, springs), they are classified according to material.

Product Name: The Chinese and English names of the declared goods, which should be specific and clear, such as "impact block for electric wrench". Brand: Fill in the brand of the tool or part, such as "Bosch", "Makita"; if no brand, fill in "no brand". Model: Fill in the model of the part or the model of the applicable tool, such as "suitable for GBH 2-26". Material: Main material, such as "alloy steel", "carbon steel", "plastic", which affects classification. Use: Clearly state for which hand-held pneumatic or power tool the part is used, such as "for electric angle grinder". Working Principle: If it is an electrical part, explain whether it depends on electrical energy to work, such as "non-electrical part". Whether Dedicated Part: Declare whether the part is dedicated to tools under heading 8467 or is a general-purpose part. Product Name: Carbon brush holder for electric angle grinder; Brand: Makita; Model: suitable for GA9020; Material: plastic + copper; Use: for electric angle grinder, conducting current; Working Principle: non-electrical part (the carbon brush holder itself does not generate electrical energy, but is it an electrical connector? Note: the carbon brush holder is an electrical part and should be classified under Chapter 85; this is only an example format and should be avoided in practice); Whether Dedicated Part: Yes. Mistakenly classifying electrical parts (such as switches, motors) under 8467.99, when they should actually be classified under Chapter 85. Mistakenly classifying general-purpose parts (such as bolts, bearings) under this code, when they should be classified according to material. Mistakenly classifying separately named parts (such as drill bits under 8207, saw blades under 8202) under this code.

Core basis for classification: 1) Whether the goods are parts of hand-held pneumatic or power tools; 2) Whether they are dedicated to such tools; 3) Whether they are electrical parts (excluded); 4) Whether they are specifically named in other headings (such as 8202, 8207). Only when all three conditions of non-electrical, non-named, and dedicated part are met can they be classified under 8467.99. 8467.91 Parts for hand-held pneumatic tools: 8467.91 is dedicated to parts for pneumatic tools, while 8467.99 covers power tool parts and other non-named parts. If the part is clearly used for pneumatic tools, it should preferentially be classified under 8467.91. 8467.92 Parts for hand-held power tools: 8467.92 is dedicated to parts for power tools, but only includes parts of electromechanical tools, not electrical parts. If the part is an electrical part, it is still classified under Chapter 85. 8207.90 Other tool parts: 8207.90 covers parts of interchangeable tools for hand tools or machine tools (such as drill bits, milling cutters), while 8467.99 is dedicated to parts of hand-held pneumatic/power tools. 8501.10 Electric motors: Electric motors are electrical parts; even if dedicated to hand-held power tools, they should be classified under 8501, not 8467.99. 8483.90 Transmission device parts: Transmission device parts (such as gears, bearings), if general-purpose parts, are classified under 8483; if dedicated to hand-held tools and not named in other headings, they may be classified under 8467.99, but careful distinction is required. Are the parts dedicated to hand-held pneumatic or power tools? Are the parts electrical parts (such as motors, switches)? Are the parts specifically named in other headings (such as drill bits, saw blades)? Are the parts general-purpose parts (such as bolts, springs)? Are the parts used for pneumatic tools (if clear, preferentially classify under 8467.91)?

What goods are specifically included in "other tool parts" under HS code 846799? Includes non-electrical dedicated parts of hand-held pneumatic or power tools, such as impact blocks, chucks, housings, handles, etc., but excludes electrical parts (such as motors, switches) and named parts (such as drill bits, saw blades). How to determine whether a part is an electrical part or a non-electrical part? Electrical parts usually involve electrical energy conversion, control or transmission, such as motors, switches, transformers, circuit boards. Non-electrical parts only serve a mechanical function, such as housings, gears, chucks. If a part has an electrical function, it should be classified under Chapter 85. Should battery packs for power tools be classified under 846799? Battery packs are usually classified under 8507 (storage batteries); even if dedicated to power tools, they are not classified under 846799 because they are electrical parts and are already named. What is the difference in classification between parts for pneumatic tools and power tools? Parts for pneumatic tools are preferentially classified under 8467.91, parts for power tools under 8467.92, and other non-named parts under 8467.99. However, electrical parts are all classified under Chapter 85. How should a part be classified if it can be used for both power tools and other machines? If the part is a general-purpose part, classify according to material (such as steel bolts under 7318); if it is a dedicated part but can be used for multiple tools, it should be determined according to the principal use; if it cannot be determined, it may be classified under 8467.99. How should "whether dedicated part" be filled in among the declaration elements for 846799? It should be truthfully filled in as "Yes" or "No". If it is a dedicated part, the applicable tool model must be provided; if it is a general-purpose part, it is recommended to classify according to material to avoid misreporting. What are the common issues in customs inspection when importing 846799 parts? Common issues include: parts mistakenly classified as electrical parts, general-purpose parts misreported as dedicated parts, inaccurate declaration of brand and model, unclear material description. It is recommended to retain technical documents for inspection. How to check the tariff rate for 846799? Through the official website of the General Administration of Customs, China International Trade Single Window, or third-party query platforms, enter the HS code and country of origin to obtain the MFN rate, general rate, and agreement rate. Rates may change, and the latest published rates shall prevail.
