Product classification
HS code for Tantalum powder: 8103.20
Tantalum, unwrought, including bars and rods obtained simply by sintering, powders.
Classification of tantalum powder under HS 8103.20
Tantalum powder is classified under HS code 8103.20, which falls within Chapter 81 of the Harmonized System, covering other base metals, cermets, and articles thereof. This specific subheading is designated for unwrought tantalum, including bars and rods obtained simply by sintering, as well as powders. The classification is determined by the physical state of the metal; because the powder has not yet been fabricated into a finished article or a semi-finished shape beyond the initial sintering or reduction process, it remains in the unwrought category. Tantalum is highly valued for its corrosion resistance and its use in electronic components, and the powder form is the primary raw material for manufacturing electrolytic capacitors and high-strength alloys.

Codes often confused with 8103.20
Common mistake. Tantalum powder is frequently confused with HS code 2615.90, which covers tantalum ores and concentrates. The distinction lies in the level of processing: 2615.90 applies to the raw mineral extracted from the earth, while 8103.20 applies to the refined metal in powder form. Additionally, it may be misclassified under 8103.90, which is the residual category for finished articles of tantalum. If the powder has been mixed with other metal powders to form a specific cermet, it might instead fall under 8113.00.
Top exporters and importers of HS 810320 (the code used for tantalum powder), 2025
In 2025, the largest exporter of HS 810320 (the code used for tantalum powder) in UN Comtrade data was the United States, with 29% of world exports; the largest importer in UN Comtrade data was the United States, with 36% 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).
