ECCN 1C231
NPATHafnium metal, hafnium alloys and compounds containing more than 60% hafnium by weight, manufactures thereof, and waste or scrap of any of the foregoing.
What This ECCN Covers
ECCN 1C231 controls hafnium metal, hafnium alloys, and compounds containing more than 60% hafnium by weight, as defined in the entry. Hafnium's neutron-absorbing properties make it relevant to reactor control elements, so it is controlled for Nuclear Nonproliferation and Anti-Terrorism reasons.
Who needs to check this?
Producers and exporters of hafnium metal and alloys for reactor, superalloy, and specialty-electronics applications.
Compliance tip
Control turns on the hafnium content threshold in the entry; distinguish hafnium from low-hafnium zirconium (1C234), which is controlled separately. With NP among the reasons, apply Part 744 nuclear end-use diligence and verify the Country Chart.
Control Reasons
Items controlled for nuclear nonproliferation reasons.
Items controlled for anti-terrorism reasons. Most items on the CCL have AT controls.
