Yes. Lamps containing mercury — including fluorescent tubes and high-intensity discharge types — may be subject to EPA TSCA import certification requirements. Additionally, the Minamata Convention on Mercury has influenced international trade flows and domestic regulatory posture toward mercury-added products. Importers should confirm current EPA notification and certification obligations before shipment.

Germicidal, UV-curing, and other discharge lamps whose primary output is in the ultraviolet spectrum are excluded from this heading and classified under the UV/infrared lamp category. The determining factor is the lamp's designed spectral output, not its physical construction — a discharge lamp physically similar to a fluorescent tube but optimized for UV emission belongs in the separate UV heading.
