SITCSection 7
U.S. imports of ballasts for discharge lamps or tubes (SITC 77123) totaled $4.8M in April 2026, traded with 36 countries.
Importers of Ballasts for Discharge Lamps or Tubes paid $381K in duties in April 2026 — an effective duty rate of 15% on $2.5M in dutiable value, based on actual customs collections rather than the published tariff schedule. Ballasts for Discharge Lamps or Tubes imports of $4.8M in April 2026 ran 16% below the year-to-date monthly average of $5.7M.
Last updated: April 2026 dataElectromagnetic and electronic ballasts regulate current flow in fluorescent, high-intensity discharge (HID), and other gas-discharge lighting systems, serving as a distinct product category from the lamps themselves. Electronic ballasts — which use solid-state circuitry to operate lamps at high frequency — have largely displaced magnetic ballasts in commercial and industrial lighting, and this technology shift affects both the applicable HTS subheading and Section 301 exposure for China-origin goods. Importers supplying lighting OEMs or the retrofit market should confirm whether a ballast is designed for fluorescent tubes, HID lamps, or LED drivers, as these distinctions can affect classification.

LED drivers are generally classified as static converters or power supplies rather than as ballasts for discharge lamps, because LEDs are not gas-discharge devices. Importers should not assume that a device marketed as a 'driver' or 'ballast' for LED lighting falls under the discharge lamp ballast heading — the underlying technology and circuit function govern classification. A CBP binding ruling is advisable for products that combine LED driver and ballast functions in a single unit.
Not necessarily — the HTS schedule may distinguish between magnetic (electromagnetic) and electronic ballasts, and the applicable subheading can differ by lamp type and ballast technology. Since duty rates and Section 301 applicability can vary by subheading, importers should identify the ballast's operating principle and target lamp type from manufacturer specifications before filing entry.
