9301.90 - Other:

This HTS category, 9301.90, encompasses "Other" military weapons that are not artillery weapons (covered by 9301.10) or rocket launchers, flame-throwers, grenade launchers, torpedo tubes, and similar projectors (covered by 9301.20). It serves as a residual category for military firearms designed for combat use that fall outside the more specific classifications within heading 9301.

The key distinction of 9301.90 lies in its exclusion of the broader artillery pieces and specialized projectile launching devices detailed in its sibling categories. While 9301.10 covers large-caliber weapons typically operated by a crew, and 9301.20 addresses dedicated launching systems for various ordnance, this category focuses on personal or crew-served firearms with other specific military applications.

To provide further granularity, this category is subdivided into more specific types of military firearms. Subcategory 9301.90.30 specifically addresses rifles, typically shoulder-fired firearms designed for long-range precision. Subcategory 9301.90.60.00 covers shotguns, which are often employed for close-quarters combat or specialized roles. Finally, 9301.90.90 acts as a further residual category for any remaining military weapons not otherwise specified within heading 9301, ensuring comprehensive coverage of military armaments.
