ECCN 6C992
ATOptical sensing fibers not controlled by 6A002.d.3 that are modified structurally to have a ‘ beat length’ of less than 500 mm (high birefringence) or optical sensor materials not described in 6C002.b and having a zinc content of equal to or more than 6% by ‘ mole fraction.’
What This ECCN Covers
ECCN 6C992 controls optical sensing fibers, not controlled by 6A002.d.3, that are modified structurally to have the characteristics in the entry — for example certain distributed-sensing fibers. These specialty sensing fibers are controlled for Anti-Terrorism reasons.
Who needs to check this?
Suppliers of optical sensing fibers for distributed temperature, strain, and acoustic sensing in industrial and infrastructure monitoring.
Compliance tip
Confirm the fiber is not caught by 6A002.d.3, then check the structural characteristics in 6C992. AT-only control limits licensing to a destination list; verify the Country Chart and screen all parties.
Control Reasons
Items controlled for anti-terrorism reasons. Most items on the CCL have AT controls.
