What This ECCN Covers

ECCN 1C210 controls "fibrous or filamentary materials" or prepregs, other than those controlled by 1C010, meeting the criteria in the entry — for example certain carbon, glass, or aramid reinforcements. These composite reinforcements have proliferation-relevant uses and are controlled for Nuclear Nonproliferation and Anti-Terrorism reasons.

Who needs to check this?

Producers and exporters of reinforcement fibers and prepregs for composite structures and pressure vessels.

Compliance tip

Rule out 1C010 first (and check 1C990 for the AT-only tier), then confirm your material against 1C210's specific-modulus and specific-strength thresholds. With NP among the reasons, apply Part 744 nuclear end-use diligence.
