Product information was submitted with your request. The item under consideration is a linear acting hydraulic cylinder (Part Number 499241-101) which will be used to control ailerons on the wing of a commercial aircraft. Specifically, it converts fluid pressure into linear force to extend or retract its piston rod. This bidirectional motion of the piston rod controls the action of the aileron. As described, the cylinder utilizes integrated lugs which mount directly to the hydraulic manifold block. In addition, it features a specialized rod-end configured to link to the structural load path of the aircraft’s airframe. The cylinder consists of corrosion resistant steel to withstand high-altitude conditions. It has an approximate outer diameter of 4 in., an approximate internal bore size of 2.75 in., and an approximate overall length of 10.75 in. You propose classification in subheading 8412.21.0075, Harmonized Tariff Schedule of the United States (HTSUS). We agree. The applicable subheading for the linear acting hydraulic cylinder (Part Number 499241-101) will be 8412.21.0075, HTSUS, which provides for “Other engines and motors, and parts thereof: Hydraulic power engines and motors: Linear acting (cylinders): Other: Other.” The general rate of duty will be Free. 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.
