An LED lamp (853952) is a complete, self-contained light source designed to replace a conventional bulb in a standard socket. An LED module (853951) is a component — a circuit board or assembly of LEDs without an integrated driver or standard base — intended for incorporation into a luminaire. The distinction matters because the two subheadings can carry different duty rates and Section 301 exposure.

Yes. Most LED lamps and modules originating in China fall under Section 301 measures. Importers should verify the specific 10-digit tariff line and current Section 301 list status, as coverage and rates have been revised across multiple rounds of action.

Sealed beam lamp units go under subheading 853910 regardless of wattage or voltage. A lamp that is not a sealed beam unit but is used in automotive applications may fall under the tungsten halogen or other filament subheadings depending on its construction, so the physical design — not the end use — drives classification.
