8204 - Hand-operated spanners and wrenches (including torque meter wrenches but not including tap wrenches); socket wrenches, with or without handles, drives or extensions; base metal parts thereof:

This HTS category, 8204, specifically enumerates hand-operated spanners and wrenches. This includes a broad array of tools designed for turning fasteners such as nuts and bolts. Notably, it encompasses torque meter wrenches, which are specialized for applying a precise amount of rotational force. However, it excludes tap wrenches, which are distinct tools used for threading operations. The classification also extends to socket wrenches, regardless of whether they are equipped with handles, drives, or extensions, as well as any parts made of base metal that are intended for these tools.

Distinguishing HTS 8204 from its sibling categories requires an understanding of its focus on hand-operated turning tools. While other categories within Section XV and Chapter 82 might cover different types of tools or base metal articles, 8204 is precise in its definition of spanners, wrenches, and their immediate accessories. For instance, it does not encompass pliers (HTS 8203), which are primarily for gripping, or screwdrivers (HTS 8205), which are for driving screws.

Within HTS 8204, further subdivisions clarify the scope. The category 8204.20.00.00 specifically isolates socket wrenches and their components. This distinction is important because socket wrenches, with their interchangeable sockets and ratcheting mechanisms, represent a significant sub-type of wrenches with unique operational characteristics compared to traditional open-end or box-end spanners. Understanding these subcategories is crucial for accurate import and export declarations, ensuring compliance with customs regulations.
