1. On 09/14/2026, Commerce published in the Federal Register its initiation of the countervailing duty investigation of certain linear hydraulic cylinders and parts thereof from the People's Republic of China, India, and Mexico (91 FR 58067). 2. The scope of these investigations covers certain linear acting hydraulic cylinders (also known as hydraulic power engines) and certain components thereof. Covered linear acting hydraulic cylinders have barrels made of steel, a bore size (inner diameter) of 25.4 mm (one inch) or more and a return (retracted) length of 101.6 mm (four inches) or more (hydraulic cylinders). For purposes of this scope, the return (retracted) length is the overall end-to-end measurement of the hydraulic cylinder unit when in the retracted position. The scope covers all hydraulic cylinders meeting the physical description above, including but not limited to the following hydraulic cylinder designs: tie-rod, welded body, telescopic, plunger, rodless, differential, position sensing, single acting, double acting, displacement, ram type, piggy-back, double rod, rod-fed and spring return hydraulic cylinders. All hydraulic cylinders are hydraulically activated. The incorporation of a spring into the design of a hydraulic cylinder otherwise meeting the description above does not exclude a product from the scope. The scope also covers the following components of hydraulic cylinders: (1) steel barrels, (2) steel piston rods, and (3) any part or component of a hydraulic cylinder that is attached to, assembled with or shipped with a covered steel barrel or a covered piston rod. Covered steel barrels include processed welded or seamless steel tubes four inches (101.6 mm) or more in length with an inner diameter of one inch (25.4 mm) or more, that have had their inner diameter precision machined (such as through honing or skiving and burnishing), and have otherwise been processed to the point of having as their sole or predominant use a barrel for an in-scope hydraulic cylinder. Such processing may include but is not limited to cutting-to-length, end finishing (e.g., machine-threading, chamfering, etc.), port drilling, and the addition of any weldments, ports, valves, sensors, end caps, gaskets, seals, rings, or any other part, component or attachment for a hydraulic cylinder, or any combination thereof. The addition of any part of a hydraulic cylinder to a barrel has thereby been processed to the point of having as its sole or predominant use as a barrel for an in-scope hydraulic cylinder. Covered piston rods are solid or hollow steel bars or steel tubes at least four inches (101.6 mm) in length that have been hard chrome plated or chrome coated, cut to length, and machined to be a piston rod. Included in the scope are any other attachments, parts, or components that are imported with, attached to, or invoiced with a hydraulic cylinder or covered barrel or rod, including but not limited to cylinder mounting parts (e.g., flanges, trunnions, clevises, lugs, etc.), connectors attached to pistons or piston rods, pistons, rings, gaskets, seals, valves, sensors or hydraulic tubing or hydraulic lines (regardless of material) such as for connections to a hydraulic pump. The scope does not cover such attachments, parts, or components when imported or invoiced separately from a hydraulic cylinder. Also included in the scope are any hydraulic cylinders and parts meeting the physical description above attached to or imported with any equipment or parts of equipment classified in Chapter 84 of the Harmonized Tariff Schedule of the United States (HTSUS). When a hydraulic cylinder is attached to or imported with any equipment or parts of equipment classified in Chapter 84 of the HTSUS, only the hydraulic cylinder is covered by the scope. The covered hydraulic cylinder in that regard includes everything in between and including the mounting pins (e.g., cylinder pin and rod pin) on either end of the cylinder. Subject merchandise also includes covered hydraulic cylinders, barrels and rods that undergo assembly or minor processing in a third country in any manner that would not otherwise remove the merchandise from the scope of these investigations if performed in the country of manufacture of the in-scope hydraulic cylinder. Subject merchandise also includes covered hydraulic cylinders, barrels and rods that are attached to any imported equipment or parts of equipment classified in Chapter 84, as discussed in the immediately preceding paragraph, if such attachment occurs in a third country. The products subject to these investigations are currently classified in the HTSUS under statistical reporting numbers 8412.21.0015, 8412.21.0030, 8412.21.0045, 8412.21.0060, 8412.21.0075, and 8412.90.9005. The HTSUS subheadings above are provided for convenience and Customs purposes only. The written description of the scope of these investigations is dispositive. 3. These proceedings have been assigned case numbers C-570-241, C-533-953, and C-201-871. 4.
