8207.19.30.90 - Other

This HTS classification, 8207.19.30.90, encompasses "Other" rock drilling or earth boring tools, and their parts thereof, which do not meet the specific alloying element criteria of the preceding subcategory. Specifically, this category applies to tools where the cutting part contains by weight *not more than* 0.2 percent of chromium, molybdenum, or tungsten, or *not more than* 0.1 percent of vanadium. These tools are designed for excavation, extraction, or exploration within geological formations and can be utilized with hand tools, power-operated tools, or machine tools.

The distinction between this category and its sibling, 8207.19.30.60 (Rotary rock drill bits, core bits and reamers), lies in the material composition of the cutting elements. While 8207.19.30.60 specifically refers to rotary bits and reamers regardless of their specific alloy content (as long as they are rock drilling or earth boring tools), this category 8207.19.30.90 is for any other rock drilling or earth boring tool and its parts that *do not* contain the higher concentrations of specified alloying metals. This implies tools made from less specialized steel alloys or other materials that may still perform rock drilling or earth boring functions.

As this is a leaf node, there are no further subcategories for this classification. Classification at this level is determined by the absence of the higher percentage thresholds for chromium, molybdenum, tungsten, or vanadium in the cutting part of the rock drilling or earth boring tool. Therefore, careful examination of the material composition of the cutting elements is crucial for accurate classification. Examples might include certain types of spades, augers, or specialized chisels used in earth boring or rock breaking operations that are not classified under the more specific categories.
