Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If primarily designed for ultraviolet output
Ultraviolet mercury lamps shift to 8539.31 due to specific UV wavelength emission, excluding general lighting mercury vapor types.
If classified as a metal halide lamp variant
Presence of metal halides in addition to mercury changes classification to metal halide lamps under 8539.22.
If imported pre-assembled into a complete lighting fixture
Assembled luminaires with mercury vapor lamps fall under Chapter 94 as finished lighting fittings rather than individual lamps.

Import Tips & Compliance
• Verify lamp specifications match mercury vapor classification; provide technical datasheets showing mercury fill and non-UV design to avoid misclassification
• Check for hazardous material declarations due to mercury content; comply with EPA and TSCA regulations for import documentation
• Ensure packaging prevents breakage, as damaged lamps may trigger waste classification issues under environmental laws
