HS Code 7904.00 – Zinc; bars, rods, profiles and wire
HS code 7904.00 is the 6-digit subheading for zinc, bars, rods, profiles and wire. It is used for zinc wire for thermal spraying, zinc rods for anodes, zinc bars for machining, zinc profiles for construction and zinc welding wire.
What HS 7904.00 covers
This HS code encompasses semi-finished zinc products in various elongated forms, including solid bars, rods, profiles (shaped sections), and wire. These products serve as essential intermediate materials for further manufacturing processes such as drawing, machining, or forming into finished components. They are widely utilized in the construction industry for applications like roofing and flashing, in electrical systems, and as components in various industrial machinery and consumer goods. Importers are typically fabricators, manufacturers, and construction companies that require these specific forms for their production lines. Exporters are often primary zinc producers or specialized metal processing companies with capabilities in extrusion and drawing. Key trade considerations include the specific alloy composition (if applicable), precise dimensions, surface finish, and compliance with relevant industry standards for mechanical properties and tolerances, ensuring suitability for diverse industrial applications.

Codes often confused with 7904.00
Common mistake. Can be confused with 790500 (zinc plates, sheets, strip, foil) if the form is flat rather than elongated, or with 790120 (unwrought zinc alloys) if the bars/rods are considered raw material rather than semi-finished products.
Top exporters and importers of HS code 790400, 2025
In 2025, the largest exporter of HS code 790400 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).
