Issued July 29, 2008 by U.S. Customs and Border Protection.
Tariff classification
HTS codes: 8547.20.0000
Headings: 8547
Product description
The item concerned is an insulating washer (Part # 23633). This circular shaped insulator has an inner diameter of 0.520 inches and an outer diameter of 1.200 inches. It is yellow in color and comprised of glass polyester. The insulator will be used in 37MT and 42MT starter motor assemblies. These starter motors incorporate a copper stud that is connected to the electrical circuitry inside the motor. The copper stud passes through a hole in the starter motor frame and is connected to a solenoid lead wire. This copper stud must be insulated from the starter frame; a series of insulating bushings is used to accomplish that task. The copper stud is fixed to the starter frame by means of a hex nut. Due to the fact that the hex nut is in intimate contact with the copper stud, it is also an electrically live component which needs to be insulated from the starter frame. In order to insulate the hex nut from metal starter frame, this insulating washer is placed between the hex nut and the starter frame. The purpose of this insulating washer is to insulate the live stud/hex nut from the grounded frame. You proposed classification under subheading 8546.10.00.00, Harmonized Tariff Schedule of the United States (HTSUS) which provides for “Electrical insulators of any material: Of glass.” However, it is the opinion of this office that the insulator (Part # 23633) is more specifically provided for in subheading 8547, which provides for “Insulating fittings for electrical machines…:”
CBP rationale
The applicable subheading for the insulator (Part # 23633) will be 8547.20.0000, Harmonized Tariff Schedule of the United States (HTSUS), which provides for “Insulating fittings for electrical machines, appliances or equipment, being fittings wholly of insulating material…: Insulated fittings of plastics.
