HS Code 8104.90 – Magnesium; articles n.e.c. in heading no. 8104
HS code 8104.90 is the 6-digit subheading for magnesium, articles n.e.c. in heading no. 8104. It is used for magnesium alloy castings, magnesium extrusions, magnesium sheets, magnesium plates and magnesium anodes (sacrificial).
What HS 8104.90 covers
This "not elsewhere specified or included" (NESOI) code for magnesium covers a diverse range of manufactured articles that are primarily made of magnesium but don't fit into other specific headings within Chapter 81. It's a catch-all for finished or semi-finished magnesium products, excluding waste, scrap, or basic unwrought forms. International trade under this code involves specialized components and products where magnesium's lightweight, strength, and other unique properties are critical. Importers are typically industries requiring high-performance materials, such as automotive, aerospace, electronics, and sports equipment manufacturers. Exporters are often countries with advanced manufacturing capabilities in magnesium fabrication. Key considerations in this trade include the specific alloy composition, manufacturing precision, surface treatments, and the intended application of the articles. The value chain for these products often involves complex engineering and design, making them higher-value goods compared to raw materials.

Codes often confused with 8104.90
Common mistake. This code can be confused with specific articles classified elsewhere by function (e.g., 8708 for automotive parts) if the magnesium component is part of a larger assembly, or with 810411/810419 (Unwrought magnesium) if the article is very basic and not clearly "manufactured."
Top exporters and importers of HS code 810490, 2025
In 2025, the largest exporter of HS code 810490 in UN Comtrade data was Austria, with 24% of world exports; the largest importer in UN Comtrade data was Saudi Arabia, with 18% 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).
