HS code for Machine tool parts: 8466.93
Parts & accessories suited for use solely/principally with machines of headings 8456-8465, n.e.c. in heading no. 8466.
Classification of machine tool parts under HS 8466.93
Parts and accessories for machine tools are classified under HS code 8466.93. Chapter 84 covers nuclear reactors, boilers, machinery, and mechanical appliances. Heading 8466 is dedicated to parts and accessories suited for use solely or principally with the machines of headings 8456 to 8465. These headings cover various machine tools for working metal, wood, stone, and other hard materials. Subheading 8466.93 specifically covers parts for machines classified under headings 8456 to 8461, which include machines for removing material by laser, ultrasonic, or electrochemical processes, as well as machining centers, lathes, and milling machines. To qualify for this code, the part must be identifiable as being intended for these specific types of metalworking machinery and must not be a tool already covered by Chapter 82 or a general-purpose part like a bearing or bolt.

Codes often confused with 8466.93
Common mistake. A common misclassification is using 8483.40 for gears or 8482.10 for ball bearings used within the machine. These are considered "parts of general use" and must be classified in their own specific headings regardless of the machine they are used in. Additionally, electronic controllers are often misclassified here but should usually be under 8537.10 if they are programmable logic controllers (PLCs).

How these figures are built
109 countries reported 2025 trade to UN Comtrade in HS 2022, and their own totals are used. Countries that did not report are estimated from what other countries recorded trading with them. Those estimates miss trade with other non-reporting countries, so they can be low, and a non-reporting country can rank higher than shown or be missing from the list. World totals add both and leave out trade between two non-reporting countries. Figures are in current US dollars; reported imports are mostly valued CIF and exports FOB, and exports include re-exports. The UN Comtrade links show the underlying records; they can also list a few reporters left out here (regional groups and older HS editions).
