This classification is distinct from other "Other" categories within 9305.91.30 as it is narrowly defined by its applicability to artillery weapons of heading 9301.10. For instance, it would not encompass parts for other types of military firearms, such as rifles or machine guns, which would fall under different subdivisions. The specificity here ensures accurate tariff treatment based on the precise type of weapon system the part or accessory is intended for.

As this is a leaf node within the HTS structure, there are no further subcategories under 9305.91.30.10. Therefore, classification at this level is definitive for parts and accessories of artillery weapons falling under 9301.10. Importers and exporters should ensure that the intended use and compatibility of the part or accessory with specific artillery weapon systems are clearly documented to support this classification.
