8207.19 - Other, including parts:

This HTS category, 8207.19, encompasses interchangeable tools designed for drilling, boring, or extracting from rock or earth, along with their constituent parts made of base metal. These tools are distinct from other interchangeable tools classified under 8207, as their primary function is geological exploration, excavation, or construction in challenging subterranean environments.

Unlike sibling category 8207.13, which specifically designates rock drilling or earth boring tools with a working part composed of cermets, category 8207.19 covers all other rock drilling or earth boring tools and their parts. This means that if the tool's working part is not made of cermets, it will likely fall within this broader classification.

Within 8207.19, further distinctions are made based on the material composition of the cutting part. Subcategory 8207.19.30 addresses tools where the cutting part contains significant amounts of chromium, molybdenum, tungsten, or vanadium, indicating specialized applications requiring enhanced durability or cutting performance. All other rock drilling and earth boring tools and parts not meeting the specific material criteria of 8207.19.30 are classified under 8207.19.60, serving as a residual category for items within this group.
