U.S. imports of tantalum crucibles (HS 810391) totaled $1.1M in April 2026, traded with 4 countries.
Tantalum Crucibles imports of $1.1M in April 2026 ran 141% above the year-to-date monthly average of $453K.
Last updated: April 2026 dataMachined or formed from high-purity tantalum, crucibles under 8103910000 serve as containment vessels in crystal-growth furnaces, vacuum metallurgy, and chemical processing where extreme corrosion resistance and high melting point are essential. China is the leading supplier, with Liechtenstein — home to a globally significant specialty-metals fabricator — and Austria also prominent sources. The narrow end-use profile of tantalum crucibles means that importers are typically industrial buyers with specific dimensional and purity requirements, and misclassification risk arises when crucibles are imported as part of a larger furnace assembly.
AI-written summary of the official U.S. Census Bureau trade figures on this page — verify before relying on it.
A tantalum crucible imported separately is classified under 8103910000 as an article of tantalum. However, if it is imported as an integral part of a complete furnace or crystal-growth system, GRI 1 and the relevant section notes may require classification with the complete machine. Importers bringing in crucibles as spare parts for existing equipment should confirm with a licensed customs broker whether the 'parts' provisions of the applicable machinery heading apply.
Commercial tantalum crucibles are typically produced from electron-beam-melted tantalum with purity of 99.9% or higher, machined to customer-specified dimensions. Purity and dimensions do not affect the HTS classification under 8103910000, but they are critical for end-use qualification in semiconductor and sapphire crystal-growth applications. Importers should retain mill certificates and dimensional inspection reports for quality-assurance and potential CBP inquiry purposes.
