Product classification
HS code for Screw eyes: 7318.13
Iron or steel, threaded screw hooks and screw rings.
Classification of screw eyes under HS 7318.13
Screw eyes are classified under HS code 731813, which covers threaded screw hooks and screw rings made of iron or steel. The classification is based on the physical design of the fastener: a threaded shank intended to be screwed into wood or other materials, topped with a closed loop (eye) or an open hook. Under the General Rules for the Interpretation of the Harmonized System, products are classified according to the material they are made of and their specific function. Since screw eyes are essentially a variation of a screw but with a specialized head for hanging or securing items, they are grouped with other threaded fasteners in Chapter 73. The distinction between a screw hook and a screw eye is negligible for this specific HS code, as both are contained within the same subheading. The material must be iron or steel; if the item is made of another metal, such as brass, it would be classified elsewhere.

Codes often confused with 7318.13
Common mistake. Screw eyes are frequently misclassified under 731812 (other wood screws) or 731815 (other screws and bolts). While they are threaded, the presence of the eye or hook head specifically directs them to 731813. Another error is using this code for copper or brass screw eyes, which should be classified under 741533.

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).
