Products classified under HTS 8419.12.00.00
Flat Plate Solar Water Heater Panel System
A flat plate collector system with copper absorber plates and selective coating captures solar radiation to heat water circulated through an insulated tank. Classified under HTS 8419.12.00.00 for nonelectric solar-powered storage water heaters used in domestic hot water applications.
Commercial Solar Water Heating Station
Large-scale system with multiple collectors, heat exchangers, and stratification tanks for hotels or apartment buildings. HTS 8419.12.00.00 covers this nonelectric solar storage heater for commercial hot water temperature treatment.
Drainback Solar Water Heater System
Drainback design automatically drains collectors when pump stops, using distilled water to prevent freezing damage. Qualifies under HTS 8419.12.00.00 as nonelectric solar water heater despite minimal pump (classified as solar thermal equipment).
Pool Solar Water Heater Panels
Unglazed polymer panels optimized for low-temperature pool heating, circulated through existing filtration systems. Borderline HTS 8419.12.00.00 classification as solar water heater for temperature increase, though often contested.
High-Temperature Solar Water Heater for Process Heat
Concentrating solar collector producing 80-120°C water for industrial washing or preheating. HTS 8419.12.00.00 applies to solar water heaters regardless of end temperature or use.
Portable Solar Water Heater Bag
Foldable insulated bag with solar absorber for camping showers, heating 5-10 gallons. HTS 8419.12.00.00 covers solar water heaters of any size if involving temperature change process.
Evacuated Tube Solar Water Heater
This solar water heater uses vacuum-sealed glass tubes to absorb solar energy and transfer heat to water via a glycol-based heat transfer fluid. It falls under HTS 8419.12.00.00 as a nonelectric storage water heater powered by solar thermal energy for residential or commercial hot water production.
Roof-Mounted Active Solar Water Heating System
This active system features roof-mounted collectors, a circulating pump (manual or thermosiphon), and insulated storage tank for efficient hot water production. It qualifies for HTS 8419.12.00.00 as a nonelectric solar water heater involving temperature change via solar heating process.
Thermosiphon Passive Solar Water Heater
Passive thermosiphon design relies on natural convection for water circulation between roof collectors and ground-level storage tank, eliminating pumps. Falls under HTS 8419.12.00.00 for nonelectric solar storage water heaters treating water by solar heating.
Integral Collector Storage Solar Water Heater
One-piece design where water storage tank doubles as solar collector, absorbing heat directly for simple batch heating. Classified in HTS 8419.12.00.00 as nonelectric solar water heater for changing water temperature via solar process.
