What This ECCN Covers

ECCN 1A003 controls manufactures of non-"fusible" aromatic polyimides in film, sheet, tape, or ribbon form that are coated or laminated with carbon, graphite, metals, or magnetic substances. These engineered polyimide products are used in flexible electronics and aerospace, and are controlled for National Security and Anti-Terrorism reasons.

Who needs to check this?

Suppliers of polyimide films and laminates (e.g., metallized or carbon-coated) for electronics, aerospace, and specialty insulation applications.

Compliance tip

Control is limited to the non-fusible aromatic polyimide manufactures meeting the coating/lamination conditions in the entry — many ordinary polyimide films fall outside. Confirm against the entry and check the NS and AT Country Chart columns.
