ECCN 1C990
ATFibrous and filamentary materials, not controlled by 1C010 or 1C210, for use in composite structures and with a specific modulus of 3.18 × 106 m or greater and a specific tensile strength of 7.62 × 104 m or greater.
What This ECCN Covers
ECCN 1C990 covers fibrous and filamentary materials, not controlled by 1C010 or 1C210, intended for use in composite structures — the Anti-Terrorism companion entry for reinforcement fibers below the higher control thresholds. As an AT-only entry, it reaches a limited set of destinations.
Who needs to check this?
Suppliers of glass, carbon, and aramid reinforcement fibers and prepregs that fall below the 1C010/1C210 thresholds.
Compliance tip
Rule out 1C010 and 1C210 first, since those carry broader controls. AT-only control means most destinations need no license, but screen the end user and end use against the Entity and SDN lists.
Control Reasons
Items controlled for anti-terrorism reasons. Most items on the CCL have AT controls.
