Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If sold as general pathology/histology knives
Knives/blades not dedicated to microtomes classify as tools.
If blades for different microtome types or subheadings
Internal 9027.90 structure differentiates by instrument category.
If disposable medical scalpels
Surgical blades fall under Chapter 82 medical instruments.
