Mercury-Containing Thermostat Switch Scrap
Electronic assemblies from old heating systems with embedded mercury-tilt switches for temperature control. Covered by HTS 8549.31.00.00 due to 'mercury-switches' in the legal description for hazardous electronic waste. These are non-functional units collected for mercury reclamation.

Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If functional mercury switches imported separately
Operational switches classify as complete electrical apparatus under 8536, not waste
If part of larger non-hazardous electrical scrap without mercury
Electrical scrap without listed hazardous components falls under general 8548.90 waste
