HS Code for Micrometers

Micrometers are classified under HS code 9017.30. This classification is governed by Chapter 90, which covers optical, photographic, cinematographic, measuring, checking, precision, medical or surgical instruments and apparatus. Heading 9017 specifically includes drawing, marking-out, or mathematical calculating instruments and instruments for measuring length, for use in the hand. Subheading 9017.30 is the specific provision for micrometers, calipers, and gauges. The classification applies regardless of whether the micrometer is a traditional mechanical analog device or a modern digital version with an LCD screen, as the primary function remains the manual measurement of linear dimensions.

Products Included

• External and internal micrometers
• Digital electronic micrometers
• Depth micrometers
• Micrometer heads for integration into machinery

Common Misclassification

Micrometers are sometimes incorrectly classified under HS code 9031.80, which is a residual category for "other" measuring or checking instruments. However, because 9017.30 specifically names micrometers, it takes precedence according to GRI 3(a). Another error is classifying them under 8205 as general hand tools; while they are used by hand, their high-precision measuring nature requires classification in Chapter 90.

FAQ

What is the HS code for micrometers?

The HS code for micrometers is 9017.30, which also includes calipers and various types of gauges.

Does the HS code change for digital micrometers?

No, both digital and analog micrometers are classified under 9017.30 as they perform the same fundamental measuring function.
