HS Code 7213.91 – Iron or non-alloy steel; bars and rods, hot-rolled, in irregularly wound coils, n.e.c. in heading no. 7213, of circular cross-section measuring less than 14mm in diameter
HS code 7213.91 is the 6-digit subheading for iron or non-alloy steel, bars and rods, hot-rolled, in irregularly wound coils, n.e.c. in heading no. 7213, of circular cross-section measuring less than 14mm in diameter. It is used for low carbon wire rod, high carbon wire rod (small diameter), welding wire rod, mesh wire rod and fastener wire rod.
What HS 7213.91 covers
This code pertains to hot-rolled bars and rods of iron or non-alloy steel, in irregularly wound coils, of a circular cross-section measuring less than 14mm in diameter, and not falling under other specific categories within heading 7213. Essentially, this covers smaller diameter plain wire rod. It serves as a fundamental raw material for a vast array of downstream products, including drawing into various types of wire (e.g., welding wire, spring wire, mesh wire), fasteners, and small components. Importers are typically wire drawing plants, fastener manufacturers, and agricultural equipment producers. Trade is high-volume and globally distributed, reflecting its essential role in manufacturing and construction supply chains worldwide.

Codes often confused with 7213.91
Common mistake. Often confused with 721399 (larger diameter wire rod) due to the 14mm diameter threshold, or 721310 (deformed wire rod) if the 'plain' aspect is overlooked.
Top exporters and importers of HS code 721391, 2025
In 2025, the largest exporter of HS code 721391 in UN Comtrade data was China, with 35% of world exports; the largest importer in UN Comtrade data was the United States, with 7.5% of world imports.

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).
