HS Code 79.04 – Zinc; bars, rods, profiles and wire
What HS 79.04 covers
Heading 7904 encompasses zinc in the form of bars, rods, profiles, and wire, representing semi-finished forms of zinc that have undergone initial shaping processes. This classification covers products typically created through extrusion, drawing, or rolling, resulting in uniform cross-sections. Zinc bars are solid, usually rectangular or circular in cross-section; rods are similar but generally smaller in diameter; profiles are shapes with constant cross-sections other than simple rectangles or circles (e.g., L-shapes, T-shapes); and wire refers to elongated strands of zinc, typically of small, uniform cross-section. The scope includes both pure zinc and zinc alloys where zinc predominates by weight. These forms are distinct from unwrought zinc (7901) as they are processed beyond simple casting, but they are not yet finished articles (7907). Accurate classification is crucial for trade compliance as it influences tariff rates, especially in regions with specific duties for semi-finished metals. It also impacts trade statistics and supply chain management for industries relying on these forms. Historically, zinc has been shaped into these forms for construction, electrical, and cathodic protection applications. This heading is fundamental to Chapter 79, providing versatile intermediate products that are further processed into a vast array of final zinc articles, from architectural elements to battery components and sacrificial anodes.

- Examples
A German manufacturer exports zinc profiles, specifically L-shaped and T-shaped sections, for architectural applications like roofing edges and facade elements, to construction projects across Scandinavia via road and ferry. A US company imports zinc wire from South Korea, primarily for use in thermal spray coatings to protect large steel structures and bridges from corrosion, typically via ocean freight in large spools. A Chinese producer ships zinc rods, specifically designed as sacrificial anodes, to shipyards in the Middle East for cathodic protection of marine vessels and offshore platforms, usually in bulk container shipments.

Codes often confused with 79.04
Common mistake. A common mistake is confusing these semi-finished forms (7904) with unwrought zinc (7901) if the bars or rods are very rudimentary or irregular, lacking the consistent cross-section indicative of drawing or extrusion. Another error involves misclassifying very wide and thin profiles as plates or sheets (7905). The key distinction lies in the 'bar, rod, profile, and wire' definition, implying a continuous, uniform cross-section typically produced by extrusion or drawing, as opposed to the broad, flat forms of plates and sheets or the unprocessed nature of unwrought metal.
Top exporters and importers of HS code 7904, 2025
In 2025, the largest exporter of HS code 7904 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).
