Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If imported as standalone specimen holders or columns
Parts principally used with TEMs classify in 9022 per chapter note 2(b), not as complete microscopes.
If equipped with compound microscope functions
Hybrid optical-electron systems may classify under 9011 if optical components predominate.
If for fully automated industrial models
Machines with automatic control features not solely microscopy may shift to Chapter 84.
