8467.11.50.40 - Wrenches, other than nut runners

This classification, HTS 8467.11.50.40, specifically covers pneumatic wrenches, excluding those with an integrated motor or those functioning as nut runners. These tools are designed for applying torque to fasteners, primarily bolts and nuts, and operate using compressed air as their power source. The key defining characteristic is their pneumatic operation and their function as wrenches, which implies a mechanism for gripping and rotating a fastener head.

This category is distinguished from its siblings by its precise exclusion of nut runners and rock drills. While 8467.11.50.20 includes drills, screwdrivers, and nut runners, this subcategory focuses solely on pneumatic wrenches. Similarly, rock drills, classified under 8467.11.50.10, are a distinct type of percussion tool not covered here. HTS 8467.11.50.90 serves as a residual category for other pneumatic tools of the rotary type not otherwise specified.

As a leaf node, HTS 8467.11.50.40 does not have further subcategories. Therefore, classification within this heading relies on accurately identifying the tool as a pneumatic, rotary-type tool, other than a nut runner, primarily used for applying or removing nuts and bolts through rotational force. The absence of an internal electric motor or reliance on external compressed air is also a critical determining factor for inclusion.
