Use this as a comparison hint, then confirm the final decision with legal notes and country-specific rules.
HS-6 · Subheading
846022
Machine-tools; grinding machines (excluding flat-surface), centreless, numerically controlled
Heading 8460 — Machine-tools; for deburring, sharpening, grinding, honing, lapping, polishing or otherwise finishing metal, sintered metal carbides or cermets by means of grinding stones, abrasives or polishing products
Chapter 84: Nuclear reactors, boilers, machinery
Plain-language overview
Use HS-6 846022 when importing or exporting centreless grinding machines that are numerically controlled. These machines are essential for precision grinding of cylindrical parts, such as shafts and tubes, where the workpiece is supported by a regulating wheel and a grinding wheel.
This code specifically covers machines that do not grind flat surfaces, distinguishing them from other grinding machines like surface grinders classified under different HS codes. If you're dealing with flat-surface grinding, you would look at other subheadings under HS-4 8460.
Centreless grinding machines are typically used in manufacturing processes where high precision and efficiency are required. For instance, they can be found in automotive or aerospace industries, where they help produce components with tight tolerances.
If you're considering importing a centreless grinding machine, check if it includes features like automatic feed, programmable controls, or specific attachments for different grinding operations. These details can affect classification and duty rates.
