HS Code 7217.30 – Iron or non-alloy steel; wire, plated or coated with base metals (other than zinc)
HS code 7217.30 is the 6-digit subheading for iron or non-alloy steel, wire, plated or coated with base metals (other than zinc). It is used for copper-coated steel wire, tin-plated steel wire, aluminum-coated steel wire, nickel-plated steel wire and bronze-coated steel wire.
What HS 7217.30 covers
This HS code encompasses iron or non-alloy steel wire that has been plated or coated with base metals other than zinc. This includes coatings like copper, tin, aluminum, or nickel, each imparting specific properties such as enhanced conductivity, solderability, corrosion resistance, or aesthetic appeal. These specialized wires are crucial for a range of advanced applications, including electrical conductors, welding electrodes, automotive components, and decorative items. Importers are typically manufacturers in the electronics, automotive, and specialized fabrication industries that require specific material properties. Exporters are highly specialized wire producers with advanced coating capabilities. Trade considerations include the type and thickness of the coating, wire diameter, and the specific performance requirements for the end-use, making it a niche but high-value segment of the wire market.

Codes often confused with 7217.30
Common mistake. This code is distinct from 721720 (zinc-coated) and 721710 (uncoated). The key is identifying the specific base metal used for plating or coating, ensuring it's not zinc, to avoid misclassification.
Top exporters and importers of HS code 721730, 2025
In 2025, the largest exporter of HS code 721730 in UN Comtrade data was China, with 38% of world exports; the largest importer in UN Comtrade data was Thailand, with 11% of world imports. Countries that did not report 2025 data are estimated from partner records, which can understate them.

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).
