Zinc, bars, rods, profiles and wire.
Classification of zinc wire under HS 7904.00
Zinc wire is classified under HS code 7904.00. This classification is shared with zinc bars, rods, and profiles. According to the Harmonized System's Chapter 79 notes, wire is defined as a cold-drawn product in coils, regardless of its cross-sectional shape, provided that its maximum cross-sectional dimension does not exceed a specific limit (typically 6 mm in many jurisdictions, though the HS definition focuses on the drawn nature and the coiled state). The classification is based on the material (zinc) and the manufacturing process (cold-drawing). Zinc wire is primarily used in thermal spray applications, where it is melted and sprayed onto steel surfaces to provide cathodic protection against rust. It is also used in certain electrical applications and for manufacturing small zinc components. The classification follows GRI 1, as the heading 7904 explicitly mentions wire. Because it is a semi-finished product, it is grouped with other basic shapes of zinc rather than finished articles.

Codes often confused with 7904.00
Common mistake. Zinc wire is often misclassified under HS code 8311.20 or 8311.30. These codes refer to cored wire or coated wire used for soldering, brazing, or welding with flux material. If the zinc wire is solid and does not contain a flux core or coating, it must remain in 7904.00. Another misclassification occurs with 7901.11, which is for unwrought zinc. While wire is made from unwrought zinc, the act of drawing it into a coiled wire format necessitates the move to the 7904.00 classification.
Top exporters and importers of HS 790400 (the code used for zinc wire), 2025
In 2025, the largest exporter of HS 790400 (the code used for zinc wire) in UN Comtrade data was Belgium, with 25% of world exports; the largest importer in UN Comtrade data was Austria, 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 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).
