Lesley Couch Nissan 1 Nissan Way Franklin, TN 37067 RE: The tariff classification of a crankshaft position sensor from Japan Dear Ms. Couch: In your letter dated July 28, 2026, you requested a tariff classification ruling. The merchandise under consideration is identified as a Crankshaft Position Sensor (CKP sensor), part number 237311KT0A. The subject device is comprised of a ferrite-PPS magnet along with a magneto-resistive integrated circuit (IC) within a housing with a connector at one end. The device is meant to be installed within the engine compartment of a vehicle to provide the position and speed of the engine’s crankshaft. This information is gathered by the Electronic Control Unit (ECU) of the vehicle for interpretation. The device functions as a transducer by creating a magnetic field that, when broken by the presence of a metal object (i.e. the engine part), creates an electrical signal that is then sent to the ECU for interpretation. The applicable subheading for the CKP Sensor, part number 237311KT0A will be 8543.70.4500, Harmonized Tariff Schedule of the United States (HTSUS), which provides for “Electrical machines and apparatus, having individual functions, not specified or included elsewhere in this chapter; parts thereof: Other machines and apparatus: Electric synchros and transducers; flight data recorders; defrosters and demisters with electric resistors for aircraft: Other.” The general rate of duty will be 2.6 percent ad valorem. The duties cited above are current as of this ruling’s issuance. Duty rates are provided for your convenience and are subject to change. The text of the most recent HTSUS and the accompanying duty rates are provided at https://hts.usitc.gov/. This ruling does not address the applicability of any additional duties, taxes, fees, exactions and/or other charges, which may apply to the goods discussed herein. This includes, but is not limited to, tariffs and other duties as provided for in Subchapter III to Chapter 99, HTSUS. Thus, for example, in addition to the

classification stated above, the merchandise covered by this ruling may also need to be reported with either the Chapter 99 provision under which an additional tariff applies or one of the Chapter 99 provisions covering exceptions to such tariffs.
