U.S. imports of articles of tantalum (nesoi) (HS 810399) totaled $11.3M in April 2026, traded with 15 countries.
Importers of Articles of Tantalum (NESOI) paid $460K in duties in April 2026 — an effective duty rate of 4.4% on $10.4M in dutiable value, based on actual customs collections rather than the published tariff schedule. Articles of Tantalum (NESOI) imports of $11.3M in April 2026 ran 47% above the year-to-date monthly average of $7.7M.
Last updated: April 2026 dataFinished tantalum articles not covered by more specific provisions — including chemical process equipment linings, medical implant components, and precision-machined parts — enter under 8103990000, the residual catch-all for tantalum manufactures. China leads supply, with Canada and Austria also significant; Kazakhstan's presence reflects upstream tantalum processing capacity that extends into fabricated articles. As with other NESOI provisions, the classification is valid only when no more specific heading applies, making a thorough GRI analysis essential for complex or multi-material tantalum assemblies.
AI-written summary of the official U.S. Census Bureau trade figures on this page — verify before relying on it.
Common imports include tantalum-lined chemical reactor components and heat exchangers (valued for corrosion resistance in acid environments), tantalum wire mesh and sheet fabrications, and precision-machined parts for semiconductor equipment. Medical-grade tantalum implant components also appear under this heading when not more specifically classified elsewhere.
The NESOI designation means 8103990000 applies only when no other heading more specifically describes the article. Tantalum parts identifiable as components of a specific machine, instrument, or apparatus are generally classified with that equipment under the relevant chapter. Importers should conduct a GRI analysis — and consult a licensed customs broker for complex assemblies — to determine whether the tantalum article or the host equipment heading takes precedence.
