Chapter 84 is a major category in the HS classification covering machinery, mechanical appliances, and their parts and accessories, including power machinery, agricultural machinery, machine tools, office equipment, automatic data processing equipment, bearings, transmissions, etc. Goods in this chapter generally have power drive, moving parts, or energy conversion functions, distinguishing them from electrical equipment in Chapter 85. Customs classification requires focusing on whether the goods have mechanical functions or are dedicated parts of machinery. Heading 8466 covers parts and accessories suitable for use solely or principally with the machines of headings 8456 to 8465, including work holders, dividing heads, special attachments, tool holders, lead screws, gear boxes, etc. However, note that this heading does not include goods specifically named in heading 8466 itself (such as tool holders), nor does it include general-purpose parts (such as bolts, springs) or separately presented tools (classified in Chapter 82). Code 846692 consists of 6 digits: the first 2 digits "84" represent Chapter 84 (machinery, mechanical appliances, and their parts); digits 3-4 "66" represent heading 8466 (parts and accessories suitable for use solely or principally with the machines of headings 8456 to 8465); digits 5-6 "92" represent subheading 8466.92, specifically "parts and accessories suitable for use solely or principally with machines of headings 8456, 8457, 8458, 8459, 8460 or 8461". The subheading level further distinguishes parts for different machine tool types; 8466.92 specifically refers to parts and accessories for machine tools for cutting metal or other materials (such as laser cutting machines, machining centers, lathes, grinding machines, etc.). The goods are machine tool accessories and are dedicated for use with machines of headings 8456 to 8461 (such as laser processing machines, machining centers, lathes, etc.), and are therefore classified under 8466.92. If the accessory is a general-purpose part (such as bolts, gears), it should be classified under the corresponding heading; if the accessory is a dedicated part of a machine tool but is for use with machines of heading 8462 or 8463 (such as forging or stamping machines), it should be classified under 8466.94 rather than 8466.92.

🎯 Classification Logic
Core basis for classification: 1. Whether the goods are dedicated for use solely or principally with machines of headings 8456 to 8465; 2. Whether the goods are parts or accessories of machine tools; 3. Whether the goods are more specifically named in other headings (such as tools in Chapter 82, general-purpose parts in other headings of Chapter 84). If the above conditions are met and the goods are for machines of headings 8456-8461, they are classified under 8466.92. 8466.94 Parts and accessories for machines of heading 8462 or 8463: 8466.94 applies to parts for forging machines, stamping machines, etc. (headings 8462/8463), while 8466.92 applies to parts for cutting machine tools (headings 8456-8461). 8207.xx Interchangeable tools for hand tools or machine tools: 8207 includes interchangeable tools such as drill bits, milling cutters, etc. These are independent tools, while 8466 covers parts and accessories of machine tools and does not include tools. 8483.xx Transmission shafts, gears, bearings, etc.: 8483 covers general-purpose transmission elements. If the accessory is a general-purpose gear box, it should be classified under 8483, not 8466. 8465.xx Machine tools for working wood, cork, bone, etc.: 8465 is a complete machine tool. If its parts are dedicated for 8465 machine tools, they should be classified under 8466.92 (because 8465 falls within the 8456-8461 range? Actually 8465 is a separate heading, but does 8466.92 cover 8465? According to the notes, 8466.92 covers 8456-8461, not 8465. Parts of 8465 should be classified under 8466.93? Need to verify. According to HS, 8466.92: for machines of 8456-8461; 8466.93: for 8462-8463; 8466.94: for 8464-8465. So parts of 8465 go to 8466.94? Actually 8466.94 is for 8462 or 8463, 8466.93 is for 8464, 8466.92 is for 8456-8461. Parts of 8465 have no clear provision? According to HS 2017, 8466.92: for 8456-8461; 8466.93: for 8462-8463; 8466.94: for 8464-8465. So parts of 8465 go to 8466.94. Therefore, complete machines of 8465 and parts of 8466.94 are different. Is it dedicated for machines of headings 8456-8461? Is it a part or accessory of a machine tool? Is it more specifically named in Chapter 82 or other headings of Chapter 84? Is it a general-purpose part rather than a dedicated accessory? Is it a separately presented tool or implement?
