Last updated: August 2026 dataWrought hafnium articles not elsewhere specified (8112390000) encompass machined components such as control rod segments, sputtering targets for high-k dielectric deposition, and precision parts for aerospace thermal-barrier coatings. Germany and China are the leading US import sources for this heading, with Taiwan also a notable supplier — reflecting the concentration of semiconductor equipment manufacturing and specialty metals fabrication in those markets. The small global production base for hafnium articles means supply disruptions can have outsized effects on nuclear and advanced-chip manufacturing schedules.

Classification follows the predominant metal by weight. If hafnium exceeds zirconium by weight, the article falls under the hafnium heading (811239); if zirconium predominates, it belongs under the zirconium heading (811291 or 811299). Because the two metals are chemically similar and often alloyed, a certified composition analysis is essential to support the correct classification.
Global hafnium production is tightly linked to zirconium output from a handful of major producers, so supply is relatively inelastic. Lead times for machined hafnium components can extend to several months, particularly for nuclear-grade parts requiring extensive quality certification. Buyers in the semiconductor and nuclear sectors typically maintain strategic inventory buffers and qualify multiple suppliers to manage concentration risk.
