Silicone rubber heater HS code is 8516.79.90 – Parts of electric heating resistors or heating apparatus. Actually, silicone rubber heater is essentially a flexible electric heating element, made by embedding resistance wires between layers of silicone rubber insulation. Its core function is resistive heating — converting electrical energy into heat.
These heaters are not typically sold as standalone electrical appliances, but rather as components or subassemblies integrated into various devices that require heating, such as:
