HS code for Zinc bars: 7904.00
Zinc, bars, rods, profiles and wire.
Classification of zinc bars under HS 7904.00
Zinc bars, rods, profiles, and wire are classified under HS code 790400. This classification is determined by the definitions provided in the Chapter 79 notes of the Harmonized System, which covers zinc and articles thereof. According to these notes, bars and rods are products that have not been worked further than being rolled, extruded, drawn, or forged. They must have a uniform solid cross-section along their entire length in the shape of circles, ovals, rectangles, squares, equilateral triangles, or regular convex polygons. The classification 790400 is applied to these semi-manufactured forms that serve as raw materials for further industrial production. The material must be solid; hollow sections would generally be classified as tubes or pipes under 7906. The manufacturing process is the key determinant here; while the metal is in a recognizable shape, it is not yet a finished article, but it has moved beyond the 'unwrought' stage of simple ingots or slabs.

Codes often confused with 7904.00
Common mistake. A common misclassification occurs with HS code 7901, which covers unwrought zinc. Importers often confuse cast bars (which are primary forms) with worked bars (which are semi-manufactured). If a bar is simply cast into a shape for the purpose of being remelted, it belongs in 7901. However, if it has been rolled or extruded to specific dimensions, it must be moved to 790400. Additionally, zinc wire is sometimes confused with zinc filament or very thin strips; if the product is in coils and has a cross-section exceeding 6mm, it may still be classified as a bar/rod depending on the specific regional tariff rules, though 790400 generally captures most solid profiles.

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).
