HS Code 8103.99 – Tantalum; articles n.e.c. in heading no. 8103
HS code 8103.99 is the 6-digit subheading for tantalum, articles n.e.c. in heading no. 8103. It is used for tantalum heat exchangers, tantalum medical implants, tantalum chemical processing equipment parts, tantalum sputtering targets and tantalum fasteners.
What HS 8103.99 covers
This "not elsewhere specified or included" (n.e.c.) code for tantalum covers a broad array of manufactured articles that do not fit into the more specific categories of unwrought forms, waste/scrap, or crucibles. These articles leverage tantalum's unique properties, such as extreme corrosion resistance, biocompatibility, and high melting point, for specialized industrial, medical, and electronic applications. Importers are typically high-tech manufacturers in countries like the United States, Germany, Japan, and Switzerland, requiring custom-fabricated tantalum components for demanding environments. Exporters are often nations with advanced metallurgical and precision engineering capabilities, including China, the United States, and various European countries. The trade in these articles is characterized by high value-added products, often custom-engineered, reflecting the specialized nature and critical performance requirements of the end-use applications.

Codes often confused with 8103.99
Common mistake. This code serves as a residual category and can be confused with 810320 (unwrought tantalum) if the article is minimally processed, or with 810391 (tantalum crucibles) if the item is a container but not specifically a crucible.
Top exporters and importers of HS code 810399, 2025
In 2025, the largest exporter of HS code 810399 in UN Comtrade data was China, with 60% of world exports; the largest importer in UN Comtrade data was South Korea, with 34% 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).
