What This ECCN Covers

ECCN 1C998 covers non-fluorinated polymeric substances not controlled by 1C008, as specified in the entry — the Anti-Terrorism companion for certain high-performance polymers below the 1C008 thresholds. As an AT-only entry, it applies to a limited set of destinations.

Who needs to check this?

Producers and exporters of specialty engineering polymers that fall below the 1C008 controls.

Compliance tip

Confirm the polymer is not caught by 1C008 first. AT controls require a license only to a limited destination list; verify the Country Chart and screen all parties against the Entity and SDN lists.
