The tariff classification of a fan controller assembly from South Korea
Issued January 11, 2016 by U.S. Customs and Border Protection.
Tariff classification
HTS codes: 8504.40.4000
Headings: 8504
Product description
The merchandise subject to this ruling is identified as a fan controller assembly, item code 253843M280. The fan controller assembly consists of a printed circuit board assembly (PCBA) populated with five transistors, a diode, capacitor, resistor and an input and output connector, encased between a plastic cover and a heat sink. The purpose of the fan controller assembly is to modulate the speed of the electric cooling fan motor (which in turn controls fan speed) used to cool the radiator of the engine cooling system. It does this in response to the overload/overheat signals it receives from the engine management system (EMS). Using the engine coolant temperature as an input, the EMS monitors and determines the output control signal to be sent to the fan controller assembly. If the engine temperature is too high, the EMS sends a signal to the fan controller assembly directing the fan motor to increase fan speed in order to lower the operating temperature. If the engine temperature is below the optimal range, the EMS sends a signal to the fan controller assembly directing the fan motor to decrease fan speed or to stop it in order to reduce the cooling effect. This action maintains optimal engine operating temperature.
CBP rationale
The applicable subheading for the fan controller assembly, item code 253843M280, will be 8504.40.4000, Harmonized Tariff Schedule of the United States (HTSUS), which provides for “Static converters: Speed drive controllers for electric motors.
