Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If designed for other Chapter 90 instruments like gauges
Parts for instruments other than 9017.20.70 micrometers/calipers go to the general parts heading 9017.80.
If imported as unfinished steel rods without caliper-specific machining
Unmachined or general-purpose metal rods classify as other steel articles rather than finished instrument parts.
If for use in automated measuring machines
Parts principally for industrial machinery fall under machines/apparatus parts in heading 8479.

Import Tips & Compliance
• Provide engineering drawings showing attachment mechanism to prove classification as caliper-specific parts
• Ensure material composition declaration (e.g
• 420 stainless steel) for accurate duty assessment
• Avoid bulk packaging that suggests general tool status; import in caliper accessory sets
