HS Code for Machine tool accessories

Machine tool accessories are classified under HS code 8466.93. This heading is part of Chapter 84, which deals with nuclear reactors, boilers, machinery, and mechanical appliances. Specifically, 8466 covers parts and accessories suited for use solely or principally with the machines of headings 8456 to 8465. Subheading 8466.93 is designated for accessories used with machines for working metal (headings 8456 to 8461). Classification is determined by the 'sole or principal use' rule found in Section XVI Note 2(b). If an accessory is designed specifically to enhance or enable the function of a metal-working machine tool, such as a milling machine or lathe, it falls here. This excludes general-purpose tools or parts that are classified elsewhere by their own merit. The technical nature of these accessories—ranging from indexing heads to specialized attachments—requires they be distinguished from the machines themselves, which are classified in their respective headings (e.g., 8458 for lathes).

Products Included

• Dividing heads for milling machines
• Indexing tables for machine tools
• Specialized grinding attachments
• Carriage stops for lathes
• Copying attachments for metal-working machines
• Auxiliary spindles

Common Misclassification

The most common misclassification occurs with HS code 8466.10 (tool holders) and 8466.20 (work holders). While these are also accessories, they have their own specific subheadings. 8466.93 is a residual category for accessories that do not qualify as tool or work holders. Another error is classifying these items under 8207 (interchangeable tools), which is for the actual cutting bits or drills. Accessories in 8466.93 support the machine's operation but are not the consumable cutting edge itself. Finally, parts of general use like bearings or belts should be classified in their own headings (e.g., 8482 or 4010) rather than 8466.93.
