8207.90.30 - Cutting tools with cutting part containing by weight over 0.2 percent of chromium, molybdenum, or tungsten or over 0.1 percent of vanadium

HTS Code 8207.90.30 encompasses a specific group of cutting tools designed for interchangeable use. This category primarily includes tools where the cutting part, by weight, contains over 0.2 percent of chromium, molybdenum, or tungsten, or over 0.1 percent of vanadium. These alloying elements are crucial for enhancing the hardness, strength, and wear resistance of the cutting edge, making them suitable for demanding machining operations.

Within the broader classification of "Other interchangeable tools, and parts thereof," HTS 8207.90.30 distinguishes itself by its precise material composition requirements. While other "other" interchangeable tools might exist, this subcategory is defined by the presence of specific alloy metals in its cutting elements. This focus on the metallurgical composition is a key determinant for proper classification.

This HTS code further divides into more specific subcategories to account for variations in application and tool type. These include "Hobs and other gear cutting tools" (8207.90.30.30), which are specialized for creating gear teeth, and a general "Other" category (8207.90.30.85) that captures the remaining tools fitting the described material specifications but not falling into the more specific gear-cutting designation. There is also a distinct subdivision for "For woodworking."
