9305.10.20 - Of heading 9302

This HTS category, 9305.10.20, specifically covers parts and accessories that are explicitly designed for revolvers and pistols, as distinguished from other types of firearms. These are components and attachments that, when assembled, form or are intended to form part of a revolver or pistol. This scope is derived from the parent category, which deals broadly with parts and accessories for firearms covered by headings 9301 through 9304.

The sibling category at this level, identified as "Other," would encompass parts and accessories for firearms covered by headings 9301 through 9304 that are *not* specifically revolvers or pistols. This includes components for rifles, shotguns, and other related firearms, thereby delineating the classification based on the type of firearm the part or accessory is intended for.

Within this category, further subdivisions exist to provide more granular classification. The subcategories include "Frames and receivers," which are the central structural components of a firearm, and "Other," which accounts for all remaining parts and accessories not fitting the specific "frames and receivers" designation. This hierarchical structure allows for precise identification and categorization of a wide array of firearm components.
