Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If for food or material slicing machines
Chapter 90 excludes non-medical technical uses; tissue-specific directs to 9027.
If includes integrated photographic exposure measurement
Measuring light instruments in 9027.50; pure microtomes remain 9027.90.
If precision measuring instruments for industrial QA
Lab analysis apparatus stays in 9027; Chapter 90 note 5 prioritizes 9031 for certain optical measuring.
