What This ECCN Covers

ECCN 1C226 controls tungsten, tungsten carbide, and alloys containing more than 90% tungsten by weight, meeting the form and quantity criteria in the entry. High-density tungsten has legitimate industrial uses but is also proliferation-relevant, so it is controlled for Nuclear Nonproliferation and Anti-Terrorism reasons.

Who needs to check this?

Producers and exporters of tungsten metal, tungsten carbide, and high-density tungsten alloys for tooling, radiation shielding, and industrial applications.

Compliance tip

Control turns on the tungsten content, form, and quantity thresholds in the entry — confirm your material qualifies, since many tungsten products fall outside. With NP among the reasons, apply nuclear end-use diligence and verify the Country Chart.
