Products classified under HTS 8549.31.00.00
Lead-Acid Battery Scrap from UPS Systems
Scrap consisting of used lead-acid electric accumulators recovered from uninterruptible power supply units, containing lead plates and electrolyte. Classified under HTS 8549.31.00.00 due to the presence of lead-acid accumulators, explicitly listed in the subheading for electrical and electronic waste. These are non-functional units destined for recycling.
CRT Monitor E-Waste with Activated Glass
Discarded cathode-ray tube computer monitors containing phosphor-coated activated glass from the picture tube. Falls under HTS 8549.31.00.00 because of the 'glass from cathode-ray tubes or other activated glass' explicitly mentioned. These are complete end-of-life electronic assemblies for recycling.
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.
Cadmium-Contaminated PCB Assemblies
Printed circuit boards from industrial electronics with cadmium-plated connectors and components. HTS 8549.31.00.00 applies due to 'electrical or electronic components containing cadmium' in hazardous e-waste assemblies. These boards are obsolete and suitable only for metal recovery.
NiCad Rechargeable Battery Scrap
Scrap nickel-cadmium electric accumulators from cordless power tools, containing cadmium electrodes. Classified under HTS 8549.31.00.00 for electronic waste with cadmium-containing accumulators. Fully discharged and non-rechargeable units for hazardous recycling.
PCB-Contaminated Transformer Assemblies
End-of-life electrical transformers from industrial equipment leaking polychlorinated biphenyls (PCBs) in dielectric fluid. HTS 8549.31.00.00 covers 'electrical or electronic components containing PCBs' in waste assemblies. Units exceed 50 ppm PCB threshold for hazardous classification.
Mixed E-Waste with Mercury LCD Backlights
Discarded flat-screen monitors containing CCFL backlights with mercury vapor. Falls under HTS 8549.31.00.00 as electronic assemblies with mercury-containing components. These are complete devices for lamp recycling and material recovery.
Lead-Solder Printed Circuit Boards
Obsolete PCBs from consumer electronics with lead-tin solder joints exceeding RoHS limits. HTS 8549.31.00.00 includes 'electrical or electronic components containing lead' in scrap assemblies. Boards are delisted for reuse and intended for smelting.
Spent Alkaline Primary Battery Scrap
Used household AA/AAA alkaline batteries neither usable nor rechargeable, containing heavy metals. While primarily manganese, classified under HTS 8549.31.00.00 when in electronic assemblies with listed hazards or as hazardous waste. Collected from consumer returns for recycling.
Cadmium Switchgear Electronic Scrap
Industrial electrical panels with cadmium oxide contacts from circuit breakers. HTS 8549.31.00.00 due to cadmium-containing electrical components in waste assemblies. High-voltage gear decommissioned for hazardous disposal.
PCB Fluorescent Light Ballast Assemblies
Old magnetic fluorescent lamp ballasts containing PCBs in capacitors. Classified under HTS 8549.31.00.00 for electrical components with polychlorinated biphenyls. Removed from commercial buildings for recycling.
Mercury Relay Circuit Boards
Telecom equipment PCBs with mercury-wetted reed relays for signal switching. HTS 8549.31.00.00 applies to electronic assemblies containing mercury-switches. Legacy systems replaced by solid-state alternatives.
Lead-Free but Cadmium Capacitor Scrap
Electronic scrap with silver-cadmium alloy button capacitors from power supplies. Contains cadmium explicitly listed in HTS 8549.31.00.00 for hazardous components. Vintage equipment not compliant with modern RoHS standards.
Mixed CRT Phosphor Powder Waste
Powdered activated glass phosphor scraped from dismantled CRT tubes, containing heavy metals. HTS 8549.31.00.00 covers 'other activated glass' from cathode-ray tubes in electronic waste. Generated during TV recycling processes.
Hazardous Mixed Electronics Shred
Shredded bulk e-waste from processing plants containing trace mercury switches, lead, and cadmium components. HTS 8549.31.00.00 for mixed assemblies with listed hazardous materials. Particle size <2 inches for downstream separation.
