Alternative Classifications

This product could be classified differently depending on its characteristics or intended use.

9013.80Lower: 14.5% vs 35%

If primarily for photomask/reticle inspection rather than wafers

Heading specifies wafer inspection; photomask tools use adjacent 9031.41 subheading.

9031.90Lower: 10% vs 35%

If imported as replacement parts rather than complete instruments

Parts/accessories follow classification rules but may fall into 9031.90 if not wafer-specific.

8479.89Lower: 12.5% vs 35%

If for industrial automated inspection machines not exclusively optical

Multifunction machines lose optical instrument status under Chapter 90 notes.
