HS Code 8305.10 – Stationery; fittings for loose-leaf binders or files, of base metal
HS code 8305.10 is the 6-digit subheading for stationery, fittings for loose-leaf binders or files, of base metal. It is used for ring binder mechanisms, lever arch file fittings, document clips for binders, spring clips for folders and metal file fasteners.
What HS 8305.10 covers
This HS code encompasses the essential base metal components that form the backbone of loose-leaf binders and files, crucial for organizing documents in offices, schools, and homes worldwide. These fittings are not the finished binders themselves, but the internal mechanisms like ring assemblies, lever arch mechanisms, and various clips that allow pages to be added or removed. The international trade in these items is driven by manufacturers of stationery and office supplies, who source these specialized metal parts from global suppliers. Key importers are often large-scale stationery producers or distributors, while exporters are typically specialized metal component manufacturers. Understanding the specific type of fitting and its base metal composition is vital for correct classification, as it differentiates these components from finished stationery products or plastic alternatives.

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).
