Firearms, parts and accessories, of revolvers or pistols.
Classification of revolver cylinder under HS 9305.10
The classification of a revolver cylinder falls under HS code 9305.10, which is designated for parts and accessories of revolvers or pistols. According to the General Rules of Interpretation (GRI), specifically GRI 1, classification is determined by the terms of the headings and any relative section or chapter notes. Chapter 93 covers arms and ammunition, and heading 9305 is specifically reserved for parts and accessories of the articles described in headings 9301 to 9304. Since a revolver cylinder is an essential component of a firearm classified under heading 9302, it is logically categorized within the parts subheading 9305.10. The cylinder is the rotating component of a revolver that contains multiple chambers, each holding a single cartridge. Its primary function is to align each chamber with the barrel for firing. Because it is a specialized component designed solely for use with a revolver, it meets the criteria for "parts" under the Harmonized System. This classification applies regardless of the material of construction, whether it be stainless steel, carbon steel, or specialized alloys, provided it is identifiable as a part of a firearm.

Codes often confused with 9305.10
Common mistake. A frequent error is classifying these parts under 9301, which is reserved for military weapons like machine guns or rocket launchers. While a revolver might be used by military personnel, it is generally classified under 9302, and its parts must follow under 9305.10. Another error is using 7326 for "other articles of iron or steel." While the cylinder is made of steel, the specific provision for firearm parts in Chapter 93 takes precedence over the general provision for steel articles in Chapter 73, according to the principle of specificity in GRI 3(a).

How these figures are built
109 countries reported 2025 trade to UN Comtrade in HS 2022, and their own totals are used. Countries that did not report are estimated from what other countries recorded trading with them. Those estimates miss trade with other non-reporting countries, so they can be low, and a non-reporting country can rank higher than shown or be missing from the list. World totals add both and leave out trade between two non-reporting countries. Figures are in current US dollars; reported imports are mostly valued CIF and exports FOB, and exports include re-exports. The UN Comtrade links show the underlying records; they can also list a few reporters left out here (regional groups and older HS editions).
