HS code for Zinc rods: 7904.00
Zinc, bars, rods, profiles and wire.
Classification of zinc rods under HS 7904.00
Zinc rods are classified under HS code 7904.00 according to the General Rules for the Interpretation (GRI) of the Harmonized System. This classification is determined by the material composition and the physical form of the product. Chapter 79 of the Harmonized Tariff Schedule covers zinc and articles thereof. Specifically, heading 7904 applies to zinc bars, rods, profiles, and wire. According to the Chapter 79 notes, bars and rods are defined as products that have been rolled, extruded, drawn, or forged, and possess a uniform solid cross-section along their entire length. These shapes can include circles, ovals, rectangles, squares, or equilateral triangles. The classification requires that the product has not been further worked than simple surface treatment or shaping into these specific geometric forms. If the zinc is in an unrefined or cast state without specific shaping, it would fall under a different heading. The 7904.00 code is essential for customs authorities to track the trade of semi-manufactured zinc products used in construction, manufacturing, and chemical applications.

Codes often confused with 7904.00
Common mistake. Zinc rods are frequently misclassified under HS code 7901.11 or 7901.12. These codes refer to unwrought zinc, which includes ingots, blocks, and slabs that have been cast but not further worked. The distinction lies in the manufacturing process; once an ingot is extruded or rolled into a specific rod shape, it must move from 7901 to 7904. Another common error is using HS code 7907.00, which is a residual category for other articles of zinc. 7907.00 should only be used if the rod has been further manufactured into a finished product, such as a threaded bolt or a specific machine part.

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).
