Is hafnium export-controlled?

Hafnium metal and certain compounds are listed under nuclear-related dual-use controls in most jurisdictions. We verify end-use and licence requirements before quoting; shipments carry end-user statements where required.

What zirconium content can you supply?

Standard hafnium sponge is Zr ≤ 1–3%. Low-Zr crystal bar (Zr ≤ 0.5%) and nuclear-grade (Zr < 0.2%) are quoted case by case.

Sponge and oxide: 3–6 weeks ex-works after confirmation. Crystal bar and custom compounds: 6–10 weeks.

Hafnium from China — Sponge, Crystal Bar, Oxide

Q: Typical lead time?

Sponge and oxide: 3–6 weeks ex-works after confirmation. Crystal bar and custom compounds: 6–10 weeks.

Hafnium is a strategic metal produced as a co-product of nuclear-grade zirconium refining. We source hafnium sponge, crystal bar, hafnium oxide (HfO₂) and hafnium tetrachloride (HfCl₄) from Chinese producers for superalloy, plasma-cutting, nuclear and semiconductor buyers.

Low-zirconium grades (Zr < 0.5% / < 1%) and semiconductor-grade HfO₂ (4N+) are available on request with full impurity certificates.

Compliance & quality

Every enquiry is screened before quotation: strategic-items self-classification (Korea YESTRADE) and buyer screening against the U.S. Consolidated Screening List and UN/EU sanctions lists. We do not quote sanctioned parties, military end-users or embargoed destinations.
Materials ship with mill/producer certificates of analysis (ICP-MS/GDMS as applicable). Samples are available for independent third-party assay before volume orders.
Semiconductor finished goods are sourced on a demand basis from authorised Chinese producers and distributors only — no EOL brokerage, no unverified stock. Sample lots are verified before shipment.
