8208.10.00.30 - Over 30.5 cm in length, for metal shearing machines or over 15.2 cm in diameter for metal shearing/slitting machines

This HTS category, 8208.10.00.30, specifically covers cutting blades and knives designed for use in metalworking machinery, with particular emphasis on their dimensions. It encompasses blades exceeding 30.5 cm in length when intended for metal shearing machines. Furthermore, it includes blades with a diameter greater than 15.2 cm that are utilized in metal shearing or slitting machines. The material of these blades is base metal, consistent with the broader Chapter 82 heading.

This classification is distinct from its sibling category, 8208.10.00.60, which covers "Other" blades for metalworking and their parts. While both fall under metalworking blades, 8208.10.00.30 relies on precise dimensional criteria (length or diameter) to define its scope, whereas the sibling category serves as a residual for blades that do not meet these specific size requirements or for parts thereof. The critical differentiating factor is the explicit mention of length and diameter thresholds within this category.

As this is a leaf node, there are no further subcategories. Therefore, classification within this code depends solely on the adherence of the metalworking blade to the stipulated length or diameter specifications for its intended application in shearing or slitting machines. Examples would include the large circular blades used in industrial slitting operations or the long, straight blades found in heavy-duty metal shears that exceed the specified dimensions.
