Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If rock core drilling
Hard rock coring for minerals uses the mineral boring subheading.
If with integrated testing
Core samplers with built-in testing apparatus classify as testing machines.
If multi-function geotechnical
Complex machines not principally boring may be n.e.s.i. construction equipment.
