Stationery, fittings for loose-leaf binders or files, of base metal.
Classification of loose-leaf rings under HS 8305.10
Loose-leaf rings are classified under HS code 8305.10 because they are considered fittings for loose-leaf binders or files made of base metal. This classification falls under Chapter 83, which encompasses miscellaneous articles of base metal. The Harmonized System groups these items based on their specific function as office or stationery supplies. These rings are designed to hold punched papers together and are typically made of steel, nickel-plated iron, or other base metals. The code 8305.10 is specific to the mechanisms and fittings themselves, rather than the entire binder. Whether the rings are simple circular split rings or part of a more complex multi-ring mechanism, they remain under this heading as long as they are intended for filing and stationery use.

Codes often confused with 8305.10
Common mistake. A common misclassification occurs when these items are placed under 7326.90, which is a general category for other articles of iron or steel. However, because 8305.10 is more specific to stationery fittings, it takes precedence. Another error involves plastic loose-leaf rings, which must be classified under 3926.10 as office or school supplies of plastics. Additionally, if the rings are imported as part of a complete binder, the entire product is usually classified under 4820.30 (if the binder is paper-based) or 3926.10 (if the binder is plastic), following the rule of the essential character of the composite article.

How these figures are built
109 countries reported 2025 trade to UN Comtrade in HS 2022, and their own totals are used. Countries marked * did not, so their figures add up what other countries recorded trading with them, and their exports are valued at buyers' CIF prices. 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).
