Zeiss Microtome Knife Holder
This precision knife holder is designed specifically for Zeiss microtomes used in histological sample preparation. It securely positions disposable or reusable blades for ultra-thin sectioning of tissue samples under optical microscopes. Classified under HTS 9027.90.68.00 as an optical instrument accessory for microtomes due to its integration with microscope-based pathology workflows.

Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If for electron microscopes rather than optical/light microscopes
Electron microscope microtome parts fall under dedicated subheading for EM instruments, separate from optical apparatus.
If classified as general laboratory machinery part not tied to optical analysis
Parts not principally for Chapter 90 instruments default to machines/apparatus heading per Section XVI notes.
If generic parts suitable for multiple instrument types beyond Chapter 90
Chapter 90 note 2(c) routes non-specific parts/accessories to 9033 as catch-all for working parts.

Import Tips & Compliance
• Verify compatibility certification with specific microtome models to avoid reclassification as general labware
• Include detailed technical specs showing optical integration in import documentation to justify Chapter 90 classification
