Last updated: August 2026 dataAromatic and non-aromatic imide derivatives excluding saccharin serve as intermediates across pharmaceuticals, flame retardants, and specialty polymer applications — distinctions that drive the US schedule's split into five separate 10-digit lines. Ethylenebistetrabromphthalimide (2925191000) is a brominated flame retardant subject to scrutiny under EPA chemical review programs, while aromatic imides (2925194200) and non-aromatic imides (2925199100) carry different duty treatment. The United Kingdom leads supply, with China, Japan, and India also significant sources. Aromatic lines produced by US manufacturers may be subject to additional domestic-industry note provisions.

Classification hinges on whether the imide functional group is attached to an aromatic ring system. Compounds with a benzene or naphthalene ring directly bonded to the imide nitrogen fall under the aromatic lines (e.g., 2925194200), while aliphatic-chain imides fall under the non-aromatic line (2925199100). When the structure is ambiguous, a binding ruling from CBP is advisable.
Ethylenebistetrabromphthalimide and other brominated flame retardants may be subject to TSCA Section 5 or Section 8 reporting obligations depending on their production volume and use. Importers should verify current TSCA inventory status and any applicable Significant New Use Rules before entry.
